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.
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.
