Ørsted, Simply Blue, Subsea7 Submit Application For 100 MW Scottish Floating Wind Farm
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
Ørsted, Simply Blue Group and Subsea7, through their joint venture partnership in Scotland, have submitted an offshore consent application for the proposed 100 MW Salamander floating offshore wind farm, one of the 13 projects selected in Scotland’s Innovation and Targeted Oil and Gas (INTOG) leasing round.
The article starts with a map that shows the location of the Salamander floating offshore wind farm and it shows how the sea is getting very crowded 35 kilometres off Peterhead.
This map shows the various ScotWind leases, around the North of Scotland.
The numbers are Scotwind’s lease number in their documents.
These are the Scotwind wind farms to the North-East of Scotland.
- 1 – BP Alternative Energy Investments – 859 km² – 2.9 GW – Fixed
- 2 – SSE Renewables – 859 km² – 2.6 GW – Floating
- 3 – Falck Renewables Wind – 280 km² – 1.2 GW – Floating
- 4 – Shell – 860 km² – 2.0 GW – Floating
- 5 – Vattenfall – 200 km² – 0.8 GW – Floating
- 6 – DEME – 187 km² – 1.0 GW – Fixed
- 9 – Ocean Winds – 429 km² – 1.0 GW – Fixed
- 10 – Falck Renewables Wind – 134 km² – 0.5 GW – Floating
- 11 – Scottish Power Renewables – 684 km² – 3.0 GW – Floating
- 12 – BayWa r.e. UK – 330 km² – 1.0 GW – Floating
Note.
- Salamander is located to the South of wind farms 10, 11 and 12 and to the North-West of wind farm 5.
- These windfarms total up to 16 GW.
- 4.9 GW are fixed foundation wind farms.
- 11.1 GW are floating wind farms.
These are my thoughts.
The Salamander Project
In the big scheme of things, the 100 MW Salamander wind farm, is rather a tiddler of a wind farm.
On the Salamander wind farm web site, a section gives the Project Goals.
- Our innovative pre-commercial stepping-stone concept will use novel floating foundations to (i) maximise Scottish content, (ii) enable the Scottish supply chain to gear up for the future floating offshore wind commercial opportunities in ScotWind and (iii) reduce the financial, environmental and technology risks of floating offshore wind.
- The Salamander project will contribute to the Scottish Government and UK Government net-zero targets. The project can contribute to the Scottish government’s target of 11 GW of installed offshore wind by 2030, as well as the UK government’s target of 5 GW of operational floating offshore wind by the same date.
- We are dedicated to developing a sustainable and transformative project, working with the oceans, and enabling communities to benefit from Project Salamander. Therefore, we commit to having a continuous and strong stakeholder and community engagement.
It appears to me, that the Salamander project will be a pathfinder for the 11.1 GW of floating wind farms to be built off Peterhead.
Bringing The Electricity South
National Grid are building four interconnectors between Eastern Scotland and Eastern England.
- Eastern Green Link 1 – Torness and Hawthorn Pit
- Eastern Green Link 2 – Peterhead and Drax
- Eastern Green Link 3 – Westfield and Lincolnshire
- Eastern Green Link 4 – Peterhead and Lincolnshire
Note.
- All interconnectors are 2 GW.
- All interconnectors are offshore for a long part of their route.
- It also appears that National Grid are burying much of the onshore sections.
But the 4 GW of interconnectors will only be able to bring a quarter of the offshore electricity generated in the Peterhead area to the South.
What Will Happen To The Excess Electricity?
Consider.
- There could be 16 GW of planned offshore wind power around Peterhead and North-East Scotland.
- There is only 4 GW of interconnector capacity between Peterhead and Eastern England.
- There is another 6.8 GW of electricity around North-West Scotland.
- There is 2.8 GW of electricity being developed to the East of Shetland.
- The Crown Estate is thinking of increasing the size of some offshore wind farms.
It is likely, that other wind farms will be built in the seas around the North of Scotland.
It appears that the North of Scotland could have at least 20 GW of excess electricity.
Possible solutions would include.
- Developing energy intensive industries like metal refining.
- More interconnectors to Denmark, England, Ireland and Norway.
- Storage of the electricity in giant pumped storage hydroelectric power stations.
- Creation of green hydrogen for export.
Note.
- Aluminium refining has been developed in the North of Scotland before.
- More interconnectors are a possibility, especially as Scotland is developing cable manufacturing capacity.
- Some maps show extra interconnectors between West Scotland and Merseyside.
- At least 70 GWh of pumped storage hydroelectric power stations are being developed along the Great Glen.
- I suspect that the pumped storage hydroelectric power stations could be connected to the wind farms, by cables under the waters of Loch Ness.
But surely, production of green hydrogen for export would be a very good way to go.
- Extra electrolysers could be added as required.
- Because of the interconnectors down both East and West Coasts, electrolysers could be built in England, where there is a large need for hydrogen.
- Hydrogen would be exported initially by tanker ships.
- At some point in the future, it might be viable to build a hydrogen pipeline to connect to the growing European hydrogen network.
The giant pumped storage hydroelectric power stations and the hydrogen electrolysers would be sized to make sure, that no wind power is never wasted.
Conclusion
The 100 MW Salamander floating wind farm may only be small, but it will prove the technology, the manufacturing and the supply chains, so that Scotland can have a second energy boom from the North Sea.
But this boom will certainly last longer than a hundred years.
How Germany Is Dominating Hydrogen Market
The title of this post, is the same as that of this article on Hydrogen Fuel News.
This is the sub heading.
With 3827 kilometers of pipeline across the country, Germany is blazing a trail through the continent in terms of hydrogen infrastructure growth.
These are the first two paragraphs.
Indeed, plans within the country are so far advanced that Germany is set to become the biggest importer of hydrogen in Europe and the third biggest in the world, behind global leaders China and Japan.
All this leaves the German transport sector in good stead, with a strong infrastructure supporting clean fuel adoption, while the country transitions towards net zero.
So where are the Germans going to get their hydrogen from?
One possibility is the UK.
- The UK has vast amounts of renewable energy.
- We’re only hundreds of kilometres, instead of thousands of kilometres away.
- RWE; the German energy giant has full or partial interests in about 12,3 GW of UK wind farms.
- RWE is building the Pembroke Net Zero Centre which will generate green and blue hydrogen.
Hydrogen could be exported from the UK to Germany by tanker.
Conclusion
Production and exporting of green hydrogen will become significant industry in the UK.
Consultation On Plans For Keadby Hydrogen Power Station To Begin
The title of this post, is the same as that of this press release from SSE.
These four paragraphs outline the project
SSE and Equinor will consult on plans for a new hydrogen-fired power station in North Lincolnshire which would provide vital new reliable and flexible capacity to the electricity system.
Keadby Hydrogen Power Station is a proposed 900MW plant which could be operational from 2030 – bolstering security of supply and supporting the UK’s long-term decarbonisation by providing back-up low-carbon power to variable renewable generation.
The project will enter environmental scoping in April before SSE and Equinor launch a public consultation ahead of a full planning application being made in due course.
Under plans, the new power station will be designed to run on 100% hydrogen. The ambition is that this would be the case from inception, with Government already committed to deploying low-carbon infrastructure in the Humber – the UK’s most carbon intensive cluster.
Note.
- The hydrogen for this power station will be produced by electrolysis or one of the new turquoise methods.
- It will be stored in Aldborough or Rough gas storage.
- This will be the fourth power station at Keadby after Keadby 1 (734 MW), Keadby 2 (893 MW) and Keadby 3 (910 MW)
- Keadby 3 will be fitted with carbon capture.
- These total up to 3.4 GW.
The Keadby cluster of power stations will make good backup to the wind farms in the North Sea.
Alstom Plans To Operate Its Own Passenger Train Service In The UK For The First Time
The title of this post, is the same as that of this press release from Alstom.
These two bullet points, act as sub-headings.
- Alstom is partnering with SLC Rail to form a new open access rail operation between North Wales, Shropshire, the Midlands and London
- Formal application now being submitted to the Office of Rail and Road (ORR) with passenger service sought from 2025
These are the first three paragraphs.
Alstom, global leader in smart and sustainable mobility, plans to operate a new passenger rail service across England and Wales. Working in partnership with consultancy SLC Rail, the open access operation will be known as Wrexham, Shropshire and Midlands Railway (WSMR).
As the country’s foremost supplier of new trains and train services, and a leading signalling and infrastructure provider, Alstom will operate its own rail service in the UK for the first time.
WSMR is seeking to introduce direct connectivity to and from North Wales, Shropshire, the Midlands and London that doesn’t exist today, linking growing communities and businesses, and making rail travel more convenient, enjoyable and affordable.
I can’t remember a service proposal being put forward by a train manufacturer since the privatisation of UK’s railways in the 1990s.
This is some more information and my thoughts.
The Route
This paragraph from the press release, describes the route.
The proposal envisages a service of five trains per day in each direction Monday to Saturday, with four travelling both ways on Sundays. Trains will stop at Gobowen, Shrewsbury, Telford Central, Wolverhampton, Darlaston, Walsall, Coleshill Parkway, Nuneaton and Milton Keynes on their journey between Wrexham General and London Euston.
Note.
- The proposed call at the new Darlaston station.
- The route is electrified between Euston and Nuneaton and Walsall and Wolverhampton.
- Much of the route North of Nuneaton is on tracks with a maximum speed of 70-80 mph.
The route is in these sections.
- Euston and Nuneaton – 96.7 miles – electrified
- Nuneaton and Walsall – 26.7 miles
- Walsall and Wolverhampton – 6.7 miles – electrified
- Wolverhampton and Shrewsbury – 29.7 miles
- Shrewsbury and Wrexham General – 30.3 miles
That is a total of 190.1 miles or 380.2 miles round trip.
I suspect that the service will need bi-mode trains.
Should The Service Call At Wellington?
This article on the BBC is entitled Rail Company Urged Not To Forget Wellington.
This is the sub-heading.
A rail company which is bidding to bring back a direct service between Shropshire and London has been urged not to forget a town.
These are the first three paragraphs.
Wrexham, Shropshire and Midlands Railway said it was preparing to apply to the government to run the service.
Trains would stop at Gobowen, Shrewsbury, Telford, Wolverhampton, Walsall, Coleshill and Nuneaton.
But Telford and Wrekin Council said the omission of Wellington as a stop was “short-sighted”.
Although Wellington is smaller than than Shrewsbury and Telford, it looks like a bit of analysis would provide a solution, that would be acceptable for all parties.
The Trains
In the press release, this phrase is used.
positive impact to both communities and the environment.
I can’t see any more electrification being erected on the route, so the trains will need to be bi-mode.
- Bi-mode diesel trains won’t have a positive impact on the environment.
- As the route between Wolverhampton and Wrexham General is not electrified, a battery-electric train would need a range of at least 60 miles or 120 miles for the round trip, if there were no charging at Wrexham General.
- But Alston are developing a Hydrogen Aventra, which I wrote about in Alstom And Eversholt Rail Sign An Agreement For The UK’s First Ever Brand-New Hydrogen Train Fleet.
So could Alstom be using this route to trial and showcase their new Hydrogen Aventra?
I believe that the route will be very suitable for a hydrogen train.
- Changeover between electric and hydrogen power can always take place in a station.
- All hydrogen refuelling could be performed at one end of the route.
- A large proportion of the UK’s green hydrogen is produced by INEOS at Runcorn, which is less than fifty miles from Wrexham. A refuelling tanker could supply the train, as they do on some hydrogen routes in Germany.
- London has only small amounts of hydrogen infrastructure.
I suspect that refuelling will be done at the Wrexham end of the route.
This Alstom visualisation shows the train.
But it is only a three-car train.
- That is not a problem, as Aventras can be lengthened as required to the length required for the number of passengers.
- Some Aventras, like the Class 701 trains for South Western Railway, have even been ordered as ten-car trains.
- Two three-car trains may also be the ideal capacity, running as a six-car train.
So capacity will not be a problem.
If it is assumed that Alstom’s trains for the WSMR route, can use the overhead wires, where they exist, each trip between Wrexham General and London will require a total of 86.7 miles or 140 kilometres of running on hydrogen.
- A round trip will therefor require 280 kilometres of running on hydrogen.
- But between London Euston and Nuneaton, it will just be another electric train.
- I suspect that like the similar Class 730 train, it will be capable of 110 mph on the West Coast Main Line.
- Alstom’s Coradia iLint hydrogen train has a range of around a 500-800 kilometres on hydrogen.
- The WSMR trains will probably be 100 mph trains using hydrogen on a route, where that speed is possible.
So if a Hydrogen Aventra has a similar range to the Coradia iLint, it will be able to do two round trips before refuelling.
How Long Will The Service Take?
West Midlands Trains, who use the similar Class 730 trains take one hour and eleven minutes between London Euston and Nuneaton with a single stop at Milton Keynes Central.
As the WSMR trains will use the same route, I suspect the same time can be used.
As Nuneaton and Wrexham General are 93.4 miles apart a table can be created showing the time for the rest of the journey for different average speeds
- 50 mph – 1 hour 52 minutes – 3 hours 3 minutes.
- 60 mph – 1 hour 33 minutes – 2 hours 44 minutes.
- 70 mph – 1 hour 20 minutes – 2 hours 31 minutes.
- 80 mph – 1 hour 10 minutes – 2 hours 21 minutes.
Note.
- The first time is the Nuneaton and Wrexham General time and the second time is the overall journey time.
- Typical Avanti West Coast services via Crewe and a change at Chester, take between two-and-a-half and three hours.
I suspect, if the WSMR trains can keep the speed up through the Midlands, that two hours and 30 minutes could be possible.
Could The Hydrogen Aventra Run At 125 mph Under The Wires?
In March 2018, I wrote Bombardier Bi-Mode Aventra To Feature Battery Power, which was based on this article in Rail Magazine.
These are a few points from the article.
- Development has already started.
- Battery power could be used for Last-Mile applications.
- The bi-mode would have a maximum speed of 125 mph under both electric and diesel power.
- The trains will be built at Derby.
- Bombardier’s spokesman said that the ambience will be better, than other bi-modes.
- Export of trains is a possibility.
- Bombardier’s spokesman also said, that they have offered the train to three new franchises. East Midlands, West Coast Partnership and CrossCountry.
Have Alstom looked at what they bought from Bombardier and decided the following train is possible?
- Five-cars or what the customer needs.
- 125 mph under the wires.
- Running on hydrogen away from the wires.
- 100 mph on tracks without electrification.
Obviously, maximum speeds would depend on track limits.
Looking at 125 mph Avanti West Coast trains that have a Milton Keynes stop between London Euston and Nuneaton, they can reach Nuneaton ten minutes quicker than West Midlands Trains 110 mph Class 730 trains.
Two hours and 30 minutes between London Euston and Wrexham is looking increasingly possible.
Are we seeing an audacious proposal from Alston to sell new trains to CrossCountry and a host of other franchises?
Conclusion
London Euston and Wrexham would appear to be an excellent route for an Aventra-based hydrogen train.
- It can probably cruise at 110 mph on the West Coast Main Line between London Euston and Nuneaton.
- All switchovers between electrification and hydrogen can be performed in electrified stations.
- Hydrogen would only be used North of Nuneaton.
- The train can be refuelled at Wrexham General, with fuel supplied from INEOS at Runcorn.
- Given the typical 1000 km. range of hydrogen trains, a train can probably do three round trips without refuelling.
I can see this being a service with an excellent operational record.
Energy / Sullom Voe Terminal To Be Connected To The Grid By The End Of Next Year
The title of this post, is the same as that of this article on Shetland News.
This is the sub-heading.
POWER supply to the Sullom Voe Terminal is set to be provided by two 43-kilometre underground power lines from the Gremista substation by the end of next year.
These four paragraphs outline some of EnQuest’s plans.
The on-site gas-fired power station, operated by Equans, is due to be switched off in the fourth quarter of 2025 as it no longer meets stringent carbon emission standards.
EnQuest, the operator of the terminal, gave an update on its plans for the 1,000-acre site during a Shetland suppliers forum held at Mareel on Wednesday morning.
The company was keen to present itself as one that is seeking collaborative working with the local businesses and the community as Sullom Voe transitions from an oil terminal to a green energy hub.
The company is in the middle of a “right-sizing” project that involves some significant decommissioning of equipment no longer needed to make space for long-term aspiration such as carbon capture and storage, green hydrogen production and offshore electrification.
Note.
- Two underground cables will be coming from Gremista to Sullom Voe.
- Up to seven wind turbines could fit on the site to produce power needed for green hydrogen production.
- Shetland is set to be connected to the UK national grid later this year thanks to a new 600MW HVDC subsea transmission link which will run to Caithness.
- The Sullom Voe power station, once switched off, could be “repurposed” to continue producing energy using clean fuels.
- EnQuest are certainly doing a comprehensive job on the transition.
- It looks to be a well-thought out plan to convert existing oil and gas infrastructure to a modern green asset.
This Google map shows Gremista to Sullom Voe.
Note.
- Sullum Voe is at the top of the map.
- Gremista is marked by the red arrow.
- It looks like the cable could take mainly a straight North-South route.
This second Google map shows Sullum Voe
Note.
- The Sullum Voe terminal is at the top of the map.
- Sullum Voe is a 1,000-acre site.
- In the South-West corner is the closed Scatsta airport.
This third Google map shows Lerwick.
Gremista is marked by the red arrow.
I do have some thoughts.
Scatsta Airport
Consider.
- It takes takes over three hours on a bus between Lerwick and Sullum Voe
- Scatsta Airport only closed in 2020.
Is there an opportunity for an air taxi between Lerwick and Scatsta?
Enabling The UK To Become The Saudi Arabia Of Wind?
The title of this post, is the same as that of a paper from Imperial College.
The paper can be downloaded from this page of the Imperial College web site.
This is a paragraph from the Introduction of the paper.
In December 2020, the then Prime Minister outlined the government’s ten-point plan for a green industrial revolution, expressing an ambition “to turn the UK into the Saudi Arabia of wind power generation, enough wind power by 2030 to supply every single one of our homes with electricity”.
The reference to Saudi Arabia, one of the world’s largest oil producers for many decades, hints at the significant role the UK’s energy ambitions hoped to play in the global economy.
Boris Johnson was the UK Prime Minister at the time, so was his statement just his usual bluster or a simple deduction from the facts.
The paper I have indicated is a must-read and I do wonder if one of Boris’s advisors had read the paper before Boris’s speech. But as the paper appears to have been published in September 2023, that is not a valid scenario.
The paper though is full of important information.
The Intermittency Of Wind And Solar Power
The paper says this about the intermittency of wind and solar power.
One of the main issues is the intermittency of solar and wind electricity generation, which means it cannot be relied upon without some form of backup or sufficient storage.
Solar PV production varies strongly along both the day-night and seasonal cycles. While output is higher during the daytime (when demand is
higher than overnight), it is close to zero when it is needed most, during the times of peak electricity demand (winter evenings from 5-6 PM).At present, when wind output is low, the UK can fall back to fossil fuels to make up for the shortfall in electricity supply. Homes stay warm, and cars keep moving.
If all sectors were to run on variable renewables, either the country needs to curb energy usage during shortfalls (unlikely to be popular with consumers), accept continued use of fossil fuels across all sectors (incompatible with climate targets), or develop a large source of flexibility such as energy storage (likely to be prohibitively expensive at present).
The intermittency of wind and solar power means we have a difficult choice to make.
The Demand In Winter
The paper says this about the demand in winter.
There are issues around the high peaks in heating demand during winter, with all-electric heating very expensive to serve (as
the generators built to serve that load are only
needed for a few days a year).Converting all the UK’s vehicles to EVs would increase total electricity demand from 279 TWh to 395 TWh. Switching all homes across the country to heat pumps would increase demand by a further 30% to 506 TWh.
This implies that the full electrification of the heating and transport sectors would increase the annual power needs in the country by 81%.
This will require the expansion of the electricity system (transmission capacity, distribution grids, transformers,
substations, etc.), which would pose serious social, economic and technical challenges.Various paths, policies and technologies for the decarbonisation of heating, transport, and industrial emissions must be considered in order for the UK to meet its zero-emission targets.
It appears that electrification alone will not keep us warm, power our transport and keep our industry operating.
The Role Of Hydrogen
The paper says this about the role of hydrogen.
Electrifying all forms of transport might prove difficult (e.g., long-distance heavy goods) or nigh impossible (e.g., aviation) due to the high energy density requirements, which current batteries cannot meet.
Hydrogen has therefore been widely suggested as a low-carbon energy source for these sectors, benefiting from high energy density (by weight), ease of storage (relative to electricity) and its versatility to be used in many ways.
Hydrogen is also one of the few technologies capable of
providing very long-duration energy storage (e.g., moving energy between seasons), which is critical to supporting the decarbonisation of the whole energy system with high shares of renewables because it allows times of supply and demand mismatch to be managed over both short and long timescales.It is a clean alternative to fossil fuels as its use (e.g., combustion) does not emit any CO2.
Hydrogen appears to be ideal for difficult to decarbonise sectors and for storing energy for long durations.
The Problems With Hydrogen
The paper says this about the problems with hydrogen.
The growth of green hydrogen technology has been held back by the high cost, lack of existing infrastructure, and its lower efficiency
of conversion.Providing services with hydrogen requires two to three times more primary energy than direct use of electricity.
There is a lot of development to be done before hydrogen is as convenient and affordable as electricity and natural gas.
Offshore Wind
The paper says this about offshore wind.
Offshore wind is one of the fastest-growing forms of renewable energy, with the UK taking a strong lead on the global stage.
Deploying wind turbines offshore typically leads to a higher electricity output per turbine, as there are typically higher wind speeds and fewer obstacles to obstruct wind flow (such as trees and buildings).
The productivity of the UK’s offshore wind farms is nearly 50% higher than that of onshore wind farms.
Offshore wind generation also typically has higher social acceptability as it avoids land usage conflicts and has a lower visual impact.
To get the most out of this resource, very large structures (more than twice the height of Big Ben) must be connected to the ocean floor and operate in the harshest conditions for decades.
Offshore wind turbines are taller and have larger rotor diameters than onshore wind turbines, which produces a more consistent and higher output.
Offshore wind would appear to be more efficient and better value than onshore.
The Scale Of Offshore Wind
The paper says this about the scale of offshore wind.
The geographical distribution of offshore wind is heavily skewed towards Europe, which hosts over 80% of the total global offshore wind capacity.
This can be attributed to the good wind conditions and the shallow water depths of the North Sea.
The UK is ideally located to take advantage of offshore wind due to its extensive resource.
The UK could produce over 6000 TWh of electricity if the offshore wind resources in all the feasible area of the exclusive economic zone (EEZ) is exploited.
Note.
- 6000 TWh of electricity per annum would need 2740 GW of wind farms if the average capacity factor was a typical 25 %.
- At a price of 37.35 £/MWh, 6000 TWh would be worth $224.1 billion.
Typically, most domestic users seem to pay about 30 pence per KWh.
The Cost Of Offshore Wind
The paper says this about the cost of offshore wind.
The cost of UK offshore wind has fallen because of the reductions in capital expenditure (CapEx), operational expenditure (OpEx), and financing costs.
This has been supported by the global roll-out of bigger offshore wind turbines, hence, causing an increase in offshore wind energy capacity.
This increase in installed capacity has been fuelled by several low-carbon support schemes from the UK government.
The effect of these schemes can be seen in the UK 2017 Contracts for Difference (CfD) auctions where offshore wind reached strike prices as low as 57.50 £/MWh and an even lower strike price of 37.35 £/MWh in 2022.
Costs and prices appear to be going the right way.
The UK’s Offshore Wind Targets
The paper says this about the UK’s offshore wind targets.
The offshore wind capacity in the UK has grown over the past decade.
Currently, the UK has a total offshore wind capacity of 13.8GW, which is sufficient to power more than 10 million homes.
This represents a more than fourfold increase compared to the capacity installed in 2012.
The UK government has set ambitious targets for offshore wind development.
In 2019, the target was to install a total of 40 GW of offshore wind capacity by 2030, and this was later raised to 50 GW, with up to 5 GW of floating offshore wind.
This will play a pivotal role in decarbonising the UK’s power system by the government’s deadline of 2035.
As I write this, the UK’s total electricity production is 31.8 GW. So 50 GW of wind will go a good way to providing the UK with zero-carbon energy. But it will need a certain amount of reliable alternative power sources for when the wind isn’t blowing.
The UK’s Hydrogen Targets
The paper says this about the UK’s hydrogen targets.
The UK has a target of 10 GW of low-carbon hydrogen production to be deployed by 2030, as set out in the British Energy Security Strategy.
Within this target, there is an ambition for at least half of the 10 GW of production capacity to be met through green hydrogen production technologies (as opposed to hydrogen produced from steam methane reforming using carbon capture).
Modelling conducted by the Committee on Climate Change in its Sixth Carbon Budget estimated that demand for low-carbon hydrogen across the whole country could reach 161–376 TWh annually by 2050, comparable in scale to the total electricity demand.
We’re going to need a lot of electrolyser capacity.
Pairing Hydrogen And Offshore Wind
The paper says this about pairing hydrogen and offshore wind.
Green hydrogen holds strong potential in addressing the intermittent nature of renewable generation sources, particularly wind and solar energy, which naturally fluctuate due to weather conditions.
Offshore wind in particular is viewed as being a complementary technology to pair with green hydrogen production, due to three main factors: a) the high wind energy capacity factors offshore, b) the potential for large-scale deployment and c) hydrogen as a supporting technology for offshore wind energy integration.
It looks like a match made in the waters around the UK.
The Cost Of Green Hydrogen
The paper says this about the cost of green hydrogen.
The cost of green hydrogen is strongly influenced by the price of the electrolyser unit itself.
If the electrolyser is run more intensively over the course of the lifetime of the plant, a larger volume of hydrogen will be produced and so the cost of the electrolyser will be spread out more, decreasing the cost per unit of produced hydrogen.
If the variable renewable electricity source powering the electrolyser has a higher capacity factor, this will contribute towards a
lower cost of hydrogen produced.Offshore wind in the UK typically has a higher capacity factor than onshore wind energy (up to 20%), and is around five times higher than solar, so pairing
offshore wind with green hydrogen production is of interest.
It would appear that any improvements in wind turbine and electrolyser efficiency would be welcomed.
The Size Of Wind Farms
The paper says this about the size of wind farms.
Offshore wind farms can also be larger scale, due to increased availability of space and reduced restrictions on tip heights due to planning permissions.
The average offshore wind turbine in the UK had a capacity of 3.6 MW in 2022, compared to just 2.5-3 MW for onshore turbines.
As there are fewer competing uses for space, offshore wind can not only have larger turbines but the wind farms can comprise many more turbines.
Due to the specialist infrastructure requirements for hydrogen transport and storage, and the need for economies of scale to reduce the costs of
production, pairing large-scale offshore wind electricity generation with green hydrogen
production could hold significant benefits.
I am not surprised that economies of scale give benefits.
The Versatility Of Hydrogen
The paper says this about the versatility of hydrogen.
Hydrogen is a highly adaptable energy carrier with numerous potential applications and has been anticipated by some as playing a key role in the future energy system, especially when produced through electrolysis.
It could support the full decarbonisation of “hard to decarbonise” processes within the UK industrial sector, offering a solution for areas which may be difficult to electrify or are heavily reliant on fossil fuels for high-temperature heat.
When produced through electrolysis, it could be paired effectively as an energy storage technology with offshore wind, with the potential to store energy across seasons with little to no energy degradation and transport low-carbon energy internationally.
The UK – with its significant offshore wind energy resources and targets – could play a potentially leading role in producing green hydrogen to both help its pathway to net zero, and potentially create a valuable export industry.
In RWE Acquires 4.2-Gigawatt UK Offshore Wind Development Portfolio From Vattenfall, I postulated that RWE may have purchased Vattenfall’s 4.2 GW Norfolk Zone of windfarms to create a giant hydrogen production facility on the Norfolk coast. I said this.
Consider.
- Vattenfall’s Norfolk Zone is a 4.2 GW group of wind farms, which have all the requisite permissions and are shovel ready.
- Bacton Gas terminal has gas pipelines to Europe.
- Sizewell’s nuclear power stations will add security of supply.
- Extra wind farms could be added to the Norfolk Zone.
- Europe and especially Germany has a massive need for zero-carbon energy.
The only extra infrastructure needing to be built is the giant electrolyser.
I wouldn’t be surprised if RWE built a large electrolyser to supply Europe with hydrogen.
The big irony of this plan is that the BBL Pipeline between Bacton and the Netherlands was built, so that the UK could import Russian gas.
Could it in future be used to send the UK’s green hydrogen to Europe, so that some of that Russian gas can be replaced with a zero-carbon fuel?
Mathematical Modelling
There is a lot of graphs, maps and reasoning, which is used to detail how the authors obtained their conclusions.
Conclusion
This is the last paragraph of the paper.
Creating a hydrogen production industry is a transition story for UK’s oil and gas sector.
The UK is one of the few countries that could produce more hydrogen than it consumes in hydrocarbons today.
It is located in the centre of a vast resource, which premediates positioning itself at the centre of the European hydrogen supply chains.
Investing now to reduce costs and benefit from the generated value of exported hydrogen would make a reality out of the ambition to become the “Saudi Arabia of Wind”.
Boris may or may not have realised that what he said was possible.
But certainly make sure you read the paper from Imperial College.
Thousands Pay More Tax In ‘Chaotic’ Yousaf Budget
The title of this post, is the same as that of this article in The Times.
It has this sub-heading.
Efforts to plug £1.5bn funding hole put Scotland at a disadvantage, say business leaders
I have a feeling that the rise in income tax will have unintended consequences.
The UK’s Current Hydrogen Plans
Last week, the UK Government announced grants for eleven big hydrogen projects, around the UK, with two in Scotland. The new Scottish electrolysers will be playing a large part in decarbonising the Scotch whisky industry and HGVs.
I wrote Major Boost For Hydrogen As UK Unlocks New Investment And Jobs to describe the investments scope and benefits.
The Government estimated that these grants will create 700 jobs, across the UK.
How many quality high-paid jobs will this funding create in Scotland? As two of the eleven projects are based in Scotland, it could be around 127 quality jobs.
More UK Hydrogen Plans Are On The Way
The Government also indicated that this was only the first stage of bringing hydrogen production to the UK, so I will expect more high-paid quality jobs will be created.
Projected UK Offshore Wind Power
This Wikipedia entry is a list of all installed, under-construction and proposed offshore wind farms in the UK.
Aggregating the new unbuilt wind farms says the following capacity will very likely be installed in the UK in the next few years.
- Scotland – 32, 750 MW.
- England – 25,558 MW
- Wales – 700 MW
As more proposals have been called for, particularly in the Celtic Sea, I don’t think it would be unreasonable to add perhaps another 10,000 MW.
Wind farms are also proposed for around the island of Ireland and in the waters of the Channel Islands.
Upgrading Of The National Grid
These three posts could well be forerunners of other posts, I will write in the next few months.
- National Grid Fast-Tracks Overhead Line Upgrade Project To Help Accelerate Connection Dates Of 175 Clean Energy Projects
- National Grid To Accelerate Up To 20GW Of Grid Connections Across Its Transmission And Distribution Networks
- National Grid’s London Power Tunnels Breakthrough Completes £1 Billion Project’s Tunnelling Activity
National Grid is increasing its capacity at a fast pace and will need a large number of quality engineers.
Crossrail And Electrical Engineers/Electricians
I suspect we’ll find, that when a report on the late delivery of Crossrail is published, an electrician shortage will get some of the blame.
I have friends, who are electricians. Because of the shortage of trained electricians, they were offered fortunes to work on Crossrail.
Do We Have Enough Engineers?
For all the reasons I have outlined, our path to net-zero will need a lot of trained electrical engineers and electricians and just as Crossrail showed, when there is a shortage of labour in a particular area, remuneration rises.
Electrical engineers and electricians in the British Isles will be able to pick and choose the jobs they take, just as they did with Crossrail and the other major projects being built at the same time.
Effects On Scotland
If you were an engineer, who had skills and could work on these projects, would you prefer to work on a project, where the tax rate was lower?
Scotland’s tax rise will harm their decarbonisation ambitions.
Surely, the Greens should have vetoed a tax increase, which will inevitably slow their progress to net-zero?
Or are Greens a tad short of the grey matter?
Conclusion
I believe the Scottish government has shot itself in the foot.
Major Boost For Hydrogen As UK Unlocks New Investment And Jobs
The title of this post, is the same as that of this press release from the Government.
These three bullet points, act as sub-headings.
-
Eleven new production projects will invest around £400 million up front over the next 3 years, growing the UK’s green economy
-
More than 700 jobs to be created, representing the largest number of commercial scale green hydrogen production projects announced at once anywhere in Europe
-
New certainty for industry as government sets out hydrogen ambitions, including future production, transport and storage rounds
These two paragraphs outline the investment.
Over 700 jobs will be created across the UK in a world-leading hydrogen industry from the South West of England to the Highlands of Scotland, backed by £2 billion in government funding over the next 15 years.
Energy Security Secretary Claire Coutinho today (Thursday 14 December) announced backing for 11 major projects to produce green hydrogen – through a process known as electrolysis – and confirmed suppliers will receive a guaranteed price from the government for the clean energy they supply.
Note.
- This represents the largest number of commercial scale green hydrogen production projects announced at once anywhere in Europe.
- It is green hydrogen produced by electrolysis.
- The projects appear to be distributed around the UK.
- 125 MW of new hydrogen for businesses will be delivered.
I detailed the shortlist in Hydrogen Business Model / Net Zero Hydrogen Fund: Shortlisted Projects Allocation Round 2022, which used this press release from the Government as source.
Projects And Topics
This notice from the Government lists the eleven successful projects.
Projects and topics mentioned in the notice include.
Bradford Low Carbon Hydrogen
I was very impressed, when I went to see the public exhibition of this project.
- One of the reasons for building the electrolyser, is that Bradford has too many steep hills for electric buses, so will have to use more powerful hydrogen buses.
- I also got talking to a Bradford councillor, who said that they were going to use hydrogen to attract businesses to the city.
- It’s also rather large with a capacity of 24.5 MW.
The press release also gives this comment from Gareth Mills, Managing Director at N-Gen who said.
This is an important and exciting project, not just for Bradford, but also for the wider area and the community that lives here, so we are delighted to now have financial backing from government to allow us to start work on the site.
Bradford Council declared a climate emergency in 2019 and we believe this facility will play an important role in helping the area deliver on its climate change ambitions.
We know hydrogen can support decarbonising all energy types including transport, and producing green hydrogen is central to this, so we’re really excited to work with Hygen to deliver this development.
I very much feel that other large towns and cities will follow Bradford’s example.
Carlton Power
Carlton Power is a developer, who have been successful with bids for three hydrogen production projects.
- Barrow Green Hydrogen – 21 MW
- Langage Green Hydrogen – 7 MW
- Trafford Green Hydrogen – 10.5 MW
The links go to the respective web sites.
The press release also gives this comment from Eric Adams, Carlton Power’s Hydrogen Projects Director who said.
We are delighted with today’s announcement from the Department for Energy Security and Net Zero (DESNZ). Securing contracts for each project – totalling 55MW of capacity and an investment of c£100 million, and each with planning consent – is a major achievement and places Carlton Power among the leading British companies that are helping to build the hydrogen economy in the UK.
The press release also gives this comment from Keith Clarke, Founder and Chief Executive of Carlton Power who said.
We are supporting UK industry to decarbonise their operations, supporting the UK’s efforts to reach net zero and we are a catalyst for green investment and jobs into the UK regions. Working with our financial partners, Schroders Greencoat, we can now work towards Final Investment Decisions for each scheme in the early part of next year and thereafter work to have the 3 enter commercial operation within 2 years.
Carlton Power seem pleased, they got all the projects, they wanted.
Cromarty Hydrogen Project
The Cromarty Hydrogen Project has a web site, where this is said about the background of the project.
This Proposed Development would form part of the North of Scotland Hydrogen Programme recognised in the Scottish Government’s Hydrogen Action Plan1 The North of Scotland Hydrogen Programme is a strategic programme in line with the Scottish Government’s resolve to achieve Net Zero greenhouse gas (GHG) emissions by 2045 and the UK Government’s ambition by 2050. The programme is aimed at developing hydrogen production hubs across the North of Scotland to supply hydrogen, initially to meet industrial and heavy goods vehicle (HGV) transport demand in the near term and then expand to cater to additional hydrogen demands in the future.
The Cromarty Hydrogen Project is the first project in the Scotland Hydrogen Programme. It originated from a collaboration between the Port of Cromarty Firth, ScottishPower, Glenmorangie, Whyte & Mackay and Diageo and the project originator, Storegga during the feasibility stage. This project is looking to develop a green hydrogen production hub in the Cromarty Firth region and revolves around the local distilleries forming the baseload demand for early phases of the project, which would enable them to decarbonise in line with their own ambitions and sector targets.
Note.
- In Cromarty Firth And Forth To Host First Green Freeports, I talk about how Cromarty Firth is going to be a green freeport.
- The electrolyser is a medium-sized one at 10.6 MW.
- Initially HGVs will take a large part of the output.
The distillers seem to be playing a large part. I assume it it’s because distilling needs a lot of heat to boil off all the water from a spirit.
The press release also gives this comment from Sarah Potts, Storegga’s Hydrogen Managing Director, who said.
After a lot of hard work by the integrated Storegga and ScottishPower project team, particularly over the past 18 months since the UK government launch of HAR1, I’m delighted that Cromarty has been selected by the UK government Department of Energy Security and Net Zero as one of 11 projects to be awarded a funding support contract. As an SME originating from North East Scotland, I believe Storegga is able to bring a unique perspective and ambition to deliver decarbonisation solutions for Scottish industry. We look forward to now being able to take the project forward to a final investment decision in 2024, with first production in 2026 and continuing to grow our hydrogen investments in the region.
The Cromarty Hydrogen Project appears to be a local project developed to satisfy a local need, but within Government policy.
Green Hydrogen 3
I wrote about this project in Government Hydrogen Boost To Help Power Kimberly-Clark Towards 100% Green Energy Target.
It is being developed by HYRO at Northfleet for Kimberly-Clark.
The press release also gives this comment from Alex Brierley, co-head of Octopus Energy Generation’s fund management team, who said.
This is a major milestone as this funding will enable HYRO to roll out green hydrogen projects at scale in hard-to-electrify industrial processes. Our first project will be working with Kimberly-Clark to flush away fossil fuels when manufacturing Andrex and Kleenex. We’ve got a big pipeline of projects to help even more industrial businesses decarbonise – and we’re on track to invest billions in this sector.
Note.
- Will Andrex become the bog-roll of choice for the supporters of Extinction Rebellion and Just Stop Oil?
- Octopus Energy seem to be getting their fingers into lots of projects.
- I suspect that Octopus Energy will need billions.
I very much like the way that Kimberly-Clark are going and it will be interesting, if they bring out a sales philosophy based on low-carbon manufacture.
Hydrogen Blending
The press release talks of hydrogen blending.
Ministers have also announced their decision to support hydrogen blending in certain scenarios – subject to an assessment of safety evidence and final agreement.
Currently, less than 1% of the gas in distribution networks is hydrogen. Under proposals, hydrogen could be blended with other gases in the network as an offtaker of last resort, working to reduce costs in the hydrogen sector by helping producers, and to support the wider energy system.
Hydrogen blending may help achieve the UK’s net zero ambitions, but would have a limited and temporary role as the UK moves away from the use of natural gas.
When I was a wet-behind-the-ears young engineer working on ICI’s hydrogen plant at Runcorn in the 1960s, one of the topics over coffee was how can ICI find more markets for the hydrogen they produce. I suspect a lot of the excess hydrogen went to raise steam in ICI’s power station. That wasn’t very efficient or profitable.
But suppose it is deemed safe to have up to 5 % of hydrogen in the natural gas supply. Then an electrolyser operator, would know they have an offtaker of last resort, which would in effect set a minimum price for the hydrogen.
- I believe this could help their sales of hydrogen to heavy gas users, within easy reach by pipeline or truck of the electrolyser.
- It might also attract businesses with a heavy energy usage or large carbon emissions to relocate close to an electrolyser.
Allowing hydrogen blending will also mean that no expensive hydrogen is wasted.
The government’s proposal on hydrogen blending is very sensible.
Hydrogen In Home Heating
The press release says this about using hydrogen for home heating.
Ministers have decided not to proceed with a hydrogen trial in Redcar, as the main source of hydrogen will not be available. The government recognises the potential role of hydrogen in home heating and will assess evidence from the neighbourhood trial in Fife, as well as similar schemes across Europe, to decide in 2026 whether and how hydrogen could help households in the journey to net zero.
I believe the ideal way to heat homes and other buildings depends on what is available at the building’s location.
Promising ideas are coming through, but I haven’t seen one that will suit my circumstances.
But something will come through and my engineering instinct says it will be powered by natural gas and the carbon will be captured. The system would probably work on a district-wide basis.
HyMarnham
HyMarnham is probably the most unusual of the projects.
It is a collaboration between J G Pears and GeoPura.
J G Pears describe themselves like this on their web site.
JG Pears is one of the UK’s leading processors of animal by-products and food waste. Pioneering environmentally-aware practices since we started out in 1972, we play a vital role in the agricultural and food industries.
GeoPura has this mission statement on their web site.
GeoPura has a totally zero-emissions answer to how we’re going to generate, store and distribute the vast amount of energy required to decarbonise our global economies. Clean fuels. Green fuels. We believe that renewable energy is the future.
It appears that a 9.3 MW electrolyser will be built on the site of the demolished High Marnham coal-fired power station, which is shown on this Google Map.
Note.
- The River Trent runs North-South across the map.
- There are two villages of High and Low Marnham in the middle of the map.
- The circles at the top of the map indicate the cooling towers of the demolished High Marnham power station.
- The High Marnham power station site is now owned by J G Pears.
- J G Pears Newark site is to the West of Low Marnham village.
- In the North-East corner of the map is the Fledborough viaduct, which crosses the River Trent.
- Network Rail’s High Marnham Test Track runs East-West across the map and uses the Fledborough viaduct to cross the Trent.
This second Google Map shows a close up of the former power station site.
Note.
- Network Rail’s High Marnham Test Track runs East-West across the map at the top.
- The remains of High Marnham power station can be clearly seen.
- The sub-stations that connected the power station to the grid are still in place.
This article on Energy-Pedia is entitled UK: HyMarnham Power’s Green Hydrogen Project Shortlisted for UK’s Net Zero Hydrogen Fund and contains this paragraph.
Harnessing the expertise of GeoPura and JG Pears, the site will be powered by 43 MW of new solar energy and utilises 8MW of electrolysers; establishing a long-term supply of low carbon hydrogen in the region.
Note that the electrolysers are now sized at 9.3 MW.
It looks to me like one or both companies wanted an electrolyser and J G Pears had the site, so engineers and executives of the two companies got together in a decent real ale pub, started thinking and the result is HyMarnham.
- Electricity can come from the solar panels or the National Grid.
- Excess solar electricity can be exported through the National Grid.
- There is plenty of space on the site for a hydrogen filling station for vehicles.
- There could even be a filling point for refueling hydrogen-powered trains on the High Marnham Test Track.
The Energy-Pedia article indicates that GeoPura and JG Pears would like to get started this year.
Could the partners install a small electrolyser linked to the National Grid, initially, so that Network Rail has the ability to test hydrogen trains?
InchDairnie Distillery In Scotland
I have just looked at the InchDairnie Distillery web site.
- It looks a high class product.
- The company is best described as Scotch Whisky Reimagined.
- The company is based in Fife near Glenrothes.
- They appear to have just launched a rye whisky, which they are aiming to export to Canada, Japan and Taiwan.
The press release says this about InchDairnie.
InchDairnie Distillery in Scotland, who plan to run a boiler on 100% hydrogen for use in their distilling process.
That would fit nicely with the image of the distillery.
I suspect the hydrogen will be brought in by truck.
But would a zero-carbon whisky be a hit at Extinction Rebellion and Just Stop Oil parties?
PD Ports In Teesside
The press release says this about PD Ports.
PD Ports in Teesside, who will use hydrogen to replace diesel in their vehicle fleet, decarbonising port operations from 2026
I’ve felt for some time, that ports and freight interchanges, where you have lots of cranes, trucks and other diesel-powered equipment running hither and thither, is a good application for hydrogen, as not only does it cut carbon-emissions, but it also provides cleaner air for the workforce.
PD Ports have a Wikipedia entry, where this is said about their operations.
As of 2013 PD Ports owns and operates the Ports of Tees and Hartlepool under the name Teesport. The company also operates the Hull Container Terminal at the Port of Hull, and provides stevedoring and warehousing services at the Port of Immingham; logistics and warehousing at the Port of Felixstowe, Scunthorpe, and Billingham; and operates a wharf on the Isle of Wight. The company also owns the short sea ports in Scunthorpe (Groveport), Howden (Howdendyke, River Ouse, Yorkshire), and Keadby (River Trent).
The company appears to be bigger, than just Teesport and this project could grow.
The hydrogen for this project in Teesport appears to come from Tees Green Hydrogen, which will be a 5.2 MW facility developed by EDF Renewables Hydrogen.
The press release also gives this comment from Sopna Sury, Chief Operating Officer Hydrogen RWE Generation, who said.
Today’s announcements on the first 2 hydrogen allocation rounds mark a significant milestone in the development of the UK hydrogen economy. They represent a shift from policy development to project delivery, giving industry more clarity on the route to final investment decisions. Alongside the wider policy publications, this demonstrates that the UK wants to be a leader in delivering the clean energy transition.
These early projects are vital not only in driving the production of electrolytic hydrogen but also in signalling the need to build-out the T&S infrastructure for its wider distribution.
As a company with ambitions to develop approximately 2 gigawatts of green hydrogen projects across all our markets, and to invest around 8 billion euros net in green technologies in the UK between 2024-2030, RWE looks forward to being part of building a thriving hydrogen ecosystem in the UK.
These are positive words from the German energy company; RWE.
Sofidel In South Wales
The press release says this about Sofidel.
Sofidel in South Wales, who will replace 50% of their current gas boiler consumption with hydrogen at their Port Talbot paper mill.
The Wikipedia entry for the Sofidel Group has this first paragraph.
Sofidel is an Italian multinational producer of tissue paper for sanitary and domestic use. The Sofidel Group was founded in 1966. It is one of the world leaders in the tissue paper market and the second largest producer in Europe behind Essity. The privately held company is owned by the Stefani and Lazzareschi families, has subsidiaries in 13 countries and more than 6,600 employees.
Note.
- From the Wikipedia entry, it looks like the company has a good record on sustainability and has set itself good objectives.
- Sofidel are nor far from Tata Steel, who could be another large hydrogen user.
- Port Talbot will be a support port for the wind farms in the Celtic Sea.
- This is a typical hydrogen application, which reduces emission of carbon dioxide.
- But like me, have the Italian owners of the company been impressed with some of the Italian food, I’ve eaten in South Wales?
- Are British sweeteners better than Italian ones?
- The hydrogen for this project appears to come from HyBont Bridgend, which will be a 5.2 MW facility developed by Marubeni Europower.
The press release also gives this comment from Mr Tomoki Nishino, President and CEO of Marubeni Europower Ltd, who said.
Marubeni team is very honoured to be selected as a recipient of Hydrogen Allocation Round 1. Recently in October 2023, Marubeni signed an MoU with the UK government whereby we have shown our plan to invest £10 billion (along with our partners) into UK green business. We truly hope that a combination of HAR1 funding and Marubeni’s investment help decarbonize UK through HyBont, especially in the South Wales region.
It all seems to be happening in Port Talbot.
Tees Green Hydrogen
Tees Green Hydrogen is a 5.2 MW project being developed by EDF Renewables on Teesside.
The project has a web site, which has this project description on the home page.
Tees Green Hydrogen, will be a pioneering project, using the green electricity from nearby Teesside Offshore Wind Farm along with a new solar farm, which EDF Renewables UK intends to construct near Redcar, to power its hydrogen electrolyser.
The press release also gives this comment from Tristan Zipfel, Director of Strategy and Analysis at EDF Renewables UK, who said.
Today’s announcement is a huge leap forward for green hydrogen innovation which has the capacity to guarantee the long-term sustainability of industry in the North East. We are delighted that the government has given this vote of confidence in both EDF Renewables UK, Hynamics and the capacity of the region to be a world-leader in green technology and innovation.
The press release also gives this comment from Pierre de Raphelis-Soissan, CEO at Hynamics UK, who said.
This is a very important step towards realising the potential of Tees Green Hydrogen and making a ground breaking contribution to decarbonisation in the Tees Valley. The project is uniquely placed to be scalable in order that future demand can be met as hydrogen-based technology becomes the industrial norm.
Note.
- The project will be powered by both wind and solar.
- Hynamics is a subsidiary of EDF.
- I suspect that this project will supply PD Ports with hydrogen.
This project looks like it could be just a starter for 5.2 MW.
West Wales Hydrogen
West Wales Hydrogen is a 14.2 MW project being developed by H2 Energy and Trafigura in West Wales.
The best source of information is this must-watch Youtube video.
- The company appears to be able to lease you a hydrogen truck on a pay per mile basis, at the same price as a diesel truck.
- Get the finance right for your customers and yourself and everybody will be happy.
I know it will work, as I used to own half a company that leased a lot of trucks in Ipswich.
- My experience, also says the model would work with taxis, Transit-sized vans, company cars and vehicles like Defenders.
- It would also work very well around Ipswich, like my company did.
The press release also gives this comment from Julien Rolland, CEO of H2 Energy Europe, who said.
We are very grateful for the support that the UK government has announced for our 20MW electrolytic hydrogen production facility, marking a significant milestone in our journey to develop South Wales’s first large-scale green hydrogen production plant. The facility will enable industry in South Wales to transition to using green hydrogen produced from renewable energy sources.
The green hydrogen produced at Milford Haven will be used to displace natural gas and other fossil fuels in industrial and chemical processes and contribute to the decarbonisation of the local industry. The interest that we’ve already received from local industry means we are already reviewing the opportunity to scale up the facility.
I can see this model being applied all over the UK.
Whitelee Green Hydrogen
Whitelee Green Hydrogen is a 7.1 MW project being developed by Scottish Power close to the Whitelee Wind Farm.
The Whitelee Wind Farm has a comprehensive Wikipedia entry, where this is said about the future of the wind farm.
In May 2009, the Scottish Government granted permission for an extension to the wind farm to produce up to a further 130 megawatts of power, which would increase the total generating capacity of Whitelee to 452 MW.
In 2010 a 75 turbine extension commenced, adding an additional 217 MW of capacity, enough to power the equivalent of over 124,000 homes. This brought the total generating capacity of the wind farm up to 539 MW. Additionally, the extension added a further 44 km of trails to the site. John Sisk and Son Limited and Roadbridge were jointly appointed as Principal Contractors for the site during construction with Alstom Limited erecting and commissioning the wind turbines.
In August 2012 Scottish Power announced that it was applying for a further small extension of five turbines on the west of the existing site, adding 12 MW of capacity. This was refused by the DPEA on 19 Oct 2016.
A £21 million (US$29.35 million) 50MW/50MWh grid battery is being added to improve resource utilization, with plans for a 40 MW solar farm and a 20 MW hydrogen electrolyzer.
The press release also gives this comment from Peter Jones, Director of ScottishPower Green Hydrogen Business, who said.
The first wave of production facilities like Whitelee and Cromarty will demonstrate that zero-emission hydrogen can be delivered at commercial scale and drive the development of a viable market for the green fuel.
It will also create highly skilled green jobs across the UK and quickly support a world leading supply chain.
It’s early days for this burgeoning market and government support is to be welcomed to help deliver a future green hydrogen economy.
With 539 MW of wind, 40 MW of solar and a 50MW/50MWh grid battery to drive a 7.1 MW electrolyser, this should prove to be a reliable source of green hydrogen.
My Thoughts
I have a few extra thoughts.
Coverage Is Rather Patchy
Some areas of the UK don’t seem to be well-served with green hydrogen from this funding.
- East Suffolk with all those trucks going to and from the Port of Felixstowe. There’s certainly no lack of renewable energy.
- Humberside with all its energy-hungry industries. There’s certainly no lack of renewable energy.
- Hampshire with all those trucks going to and from the ports of Portsmouth and Southampton. But there is a lack of renewable energy.
- Lincolnshire with all those trucks going to and from Immingham. There’s certainly no lack of renewable energy.
- London with all those local trucks delivering building materials to sites all over the capital. But then the current Mayor doesn’t have a hydrogen policy.
I would assume, that some of these areas will be funded for hydrogen in the second round.
SSE Thermal Acquires 50% Stake In H2NorthEast Hydrogen Project
The title of this post is the same as that of this press release from SSE Thermal.
These are the first three introductory paragraphs.
SSE Thermal has become joint owner of a blue hydrogen project in Teesside which is set to play a major role in supporting a reliable decarbonised power system by 2035 and accelerating industrial decarbonisation.
The partnership with Kellas Midstream will see the companies jointly develop H2NorthEast, a hydrogen production facility with carbon capture and storage that could help to kickstart a hydrogen economy in the Tees Valley. The agreement is for an initial consideration of <£10m to Kellas Midstream with further contingent consideration due should the project reach a financial investment decision.
In its first phase, H2NorthEast could deliver up to 355MW of blue hydrogen production capacity from 2028 with plans to scale up to more than 1GW. Offtakers would include heavy industry and power generation, either through blending into existing assets or in new hydrogen-fired plants.
Note.
- Production of 355 MW of hydrogen could start in 2028.
- Several existing processes have been converted from gas-firing to hydrogen-firing or a blend of natural gas and hydrogen firing. See Lime Kiln Fuelled By Hydrogen Shown To Be Viable.
- Teesside has quite a few industries, like steel and chemicals that theoretically could be converted to hydrogen or a hydrogen blend.
I have some thoughts.
Carbon Capture And Storage
This paragraph in the press release talks about the carbon capture and storage.
With an anticipated minimum carbon capture rate of 97%, H2NorthEast meets both UK and EU low-carbon standards. Specifically, the hydrogen produced via H2NorthEast would be fully compliant with both the UK’s Low Carbon Hydrogen Standard and is expected to be aligned with the EU Taxonomy for sustainable activities.
If the plant can achieve a carbon capture rate of 97 %, that is very good and it appears to meet the required standards.
- I also feel, that if it is of a high purity, then that could be a bonus, as it could be used in food manufacturing and other processes, where high purity is needed.
- I feel SSE should endeavour to use as much of the carbon dioxide, as it can to produce valuable by-products, which could include cement substitutes, building blocks, plasterboard and animal feed.
- Carbon dioxide can also be fed to soft fruit, salad vegetables, tomatoes, flowers and other plants in giant greenhouses or vertical farms.
- Polyester yarn can also be made from carbon dioxide.
It is my belief that this list of products will grow in the next ten years and carbon dioxide of a high purity will become an important chemical feedstock.
Replacement of Blue Hydrogen With Green
If SSE Renewables were to build an electrolyser near to H2NorthEast, they could use that to replace the blue hydrogen.
- From an offtaker’s point of view green and blue hydrogen would be identical.
- It’s just that the green hydrogen doesn’t produce any carbon dioxide.
- I can see the complex being run to produce enough carbon dioxide to supply the users that need it and producing blue and/or green hydrogen accordingly.
Hopefully, the more uses that can be found for the carbon dioxide, the less of it will need to use long-term storage.
Expanding The Plant
As blue and green hydrogen plants create an identical product, the decision of whether to add an extra blue hydrogen or green hydrogen plant can be taken solely on financial grounds.
Conclusion
This looks like it could be a very sensible decision by SSE.
INEOS Inovyn Becomes Europe’s First Green Hydrogen ISCC PLUS Fully Certificated Producer
The title of this post, is the same as that of this press release from INEOS.
These two bullet points, act as sub-headings.
- INEOS Inovyn’s Antwerp hydrogen production, has been certified under the ISCC (International Sustainability & Carbon Certification) PLUS scheme.
- We become the first European company to have our renewable hydrogen fully audited with greenhouse gas data certification.
This paragraph describes how the hydrogen is produced.
Our Antwerp site produces hydrogen through Chlor-Alkali electrolysis – the electrolysis of brine producing chlorine, caustic soda/potash, sodium hypochlorite and hydrogen. The electricity used to produce this hydrogen comes directly from wind turbines off Belgium’s North Coast.
The Castner-Kellner process, that I worked on at ICI in the 1960s produced similar products.
The Anonymous Widower
