Scotland And AquaVentus Partner On North Sea Hydrogen Pipeline Plans
The title of this post, is the same as that of this article on H2-View.
These four paragraphs introduce the deal and add some detail.
Hydrogen Scotland has committed to working with the AquaDuctus consortium on cross-border infrastructure concepts to connect Scotland’s offshore wind power to hydrogen production in the North Sea.
Under a Memorandum of Understanding (MOU), the two organisations plan to combine Scotland’s offshore wind with AquaVentus’ offshore electrolysis expertise, linking export and import goals across the North Sea.
The AquaDuctus pipeline is a planned offshore hydrogen link designed to carry green hydrogen through the North Sea, using a pipes and wires hybrid approach. The German consortium plans 10GW of offshore electrolysers in the North Sea, producing around one million tonnes of green hydrogen.
The pipeline design allows offshore wind farms to deliver electricity when the grid needs it, or convert power into hydrogen via electrolysis and transport it through pipelines.
Germany is embracing hydrogen in a big way.
- I introduce AquaVentus in AquaVentus, which I suggest you read.
- AquaVentus is being developed by RWE.
- AquaVentus connects to a German hydrogen network called H2ercules to actually distribute the hydrogen.
This video shows the structure of AquaVentus.
I clipped this map from the video.
Note.
- The thick white line running North-West/South-East is the spine of AquaVentus, that will deliver hydrogen to Germany.
- There is a link to Esbjerg in Denmark, that is marked DK.
- There appears to be an undeveloped link to Norway, which goes North,
- There appears to be an undeveloped link to Peterhead in Scotland, that is marked UK.
- There appears to be a link to just North of the Humber in England, that is marked UK.
- Just North of the Humber are the two massive gas storage sites of Aldbrough owned by SSE and Rough owned by Centrica.
- Aldbrough and Rough gas storage sites are being converted into two of the largest hydrogen storage sites in the world!
- There appear to be small ships sailing up and down the East Coast of the UK. Are these small coastal tankers, that are distributing the hydrogen to where it is needed?
When it is completed, AquaVentus will be a very comprehensive hydrogen network.
I believe that offshore electrolysers could be built in the area of the Hornsea 4, Dogger Bank South and other wind farms and the hydrogen generated would be taken by AquaVentus to either Germany or the UK.
- Both countries get the hydrogen they need.
- Excess hydrogen would be stored in Aldbrough and Rough.
- British Steel at Scunthorpe gets decarbonised.
- A 1.8 GW hydrogen-fired powerstation at Keadby gets the hydrogen it needs to backup the wind farms.
Germany and the UK get security in the supply of hydrogen.
Conclusion
This should be a massive deal for Germany and the UK.
Powering The Humber Energy Revolution
The title of this post is the same as this story on the Centrica web site.
This is the sub-heading.
From the UK’s largest industrial carbon emitter to a clean energy powerhouse, the Humber is ready to be transformed.
These are the first two paragraphs, which add more detail.
We’re prepared to invest £2 billion to keep Rough open and transform it into one of the world’s largest hydrogen storage facilities. This bold move is vital for the UK’s energy security, accelerating the energy transition and unlocking thousands of green jobs. But to make this vision a reality, we need strategic support from government.
We’ve spent time in the Humber, speaking with local communities and industry leaders to understand how this region’s infrastructure shapes lives and powers the nation.
It looks to me, that Centrica have got fed up with our useless, squabbling politicians and decided to act.
There is also a video to watch.
Doncaster-Sheffield Airport And Hydrogen
I believe that the airport of the future will need a lot of hydrogen.
I am probably more optimistic than most, that we will see hydrogen-powered aircraft by around 2035, as my calculations say it is probably the only way to move a hundred people by air at a time, without using fossil fuels.
Airports also have a large number of larger vehicles, that will I believe be ideal for hydrogen power.
Hydrogen buses and coaches will be more common, than they are now.
Heavy goods vehicles are likely to turn to hydrogen power.
Humberside has a large hydrogen network, which is fed by two massive hydrogen stores at AldBrough and Brough.
I suspect that Nimbys will object to hydrogen around airports on safety grounds.
But Doncaster Sheffield Airport could be an ideal location for an airport for hydrogen-powered aircraft.
Cold Snap Leaves Britain With Less Than A Week’s Worth Of Gas
The title of this post, are the same as that of this article on The Times.
This is the sub-heading.
The closure of Russian pipelines through Ukraine and recent weather conditions have left gas stores ‘concerningly low’
These are the first two paragraphs.
Britain has less than a week of gas supplies in storage, the country’s largest supplier has warned after plunging temperatures and high demand.
Centrica, the owner of British Gas, said the UK’s gas storage was “concerningly low” after coming under pressure this winter.
The two largest gas storage facilities in this country are both in the Humberside area.
- Aldbrough is in salt caverns North of Hull and is owned by SSE.
- Rough is under the North Sea and is owned by Centrica
Both are being converted to store hydrogen.
Some might thing that is a bit stupid if we’re short of storage, but we need the hydrogen storage for four reasons.
- To store hydrogen created by electrolysers on Humberside, which will enable heavy gas users in the area to decarbonise.
- The hydrogen will also be burnt in a 1 GW hydrogen-fired power station at Keadby to back up the wind turbines, with zero-carbon electricity.
- The hydrogen will also be sold to the Germans to replace Putin’s blood-stained gas. It will be sent to Germany in a pipeline called AquaVentus, which will also deliver Scottish hydrogen across the North Sea. Hopefully, the Germans will pay a good price for the hydrogen.
- The hydrogen will be used for transport.
The mistake the Government is making is not to develop smaller gas fields, so that domestic gas users can continue to use natural gas, until the technology to replace it with zero-carbon sources is fully developed.
Large Scale Hydrogen Storage Sites Could Reduce Customer Energy Costs By £1bn Per Year
The title of this post, is the same as this press release from Centrica.
These four paragraphs summarise the report.
Centrica and FTI report finds that hydrogen storage would help balance the UK’s energy system and reduce bills.
A net zero scenario including large scale hydrogen storage – specifically, a redeveloped Rough gas storage facility – would reduce energy costs by an additional £1bn per year by 2050.
Report also finds that a UK energy system focused on renewable generation risks high levels of intermittency without an established hydrogen market. By 2050, electricity generation from renewables could exceed total demand around 15% of the time.
Electricity generation from renewables could also rise or fall by as much as 100GW over the course of a single day. More than twice current levels of peak demand on winter evenings and the equivalent energy output from over 30 Hinkley Point C nuclear power stations.
Note.
- Hydrogen Central entitles their article about the Centrica press release Centrica Says Hydrogen Can Reduce Household Bills by £35 a Year. That’s almost a bottle of my favourite Adnams beer a week!
- I talked about the redevelopment of the Rough facility into hydrogen storage in Aberdeen’s Exceed Secures Centrica Rough Contract.
- Generating hydrogen from excess electricity and storing it until it is needed, must be an efficient way of storing electricity or powering industrial processes that need a lot of energy, if storing hydrogen makes £1bn per year!
- It should be noted that Centrica have a large interest in HiiROC, who are developing an efficient way to generate hydrogen from any hydrocarbon gas from chemical plant off-gas through biomethane to natural gas. In a perfect world a HiiROC system in a sewage works could capture the biomethane and split it into hydrogen and carbon black. The hydrogen could be used to refuel vehicles and the carbon black would be taken away to someone, who has need of it.
In some ways, it is surely sensible to have enough energy in a store, if the renewables fail. As Rough is already there and functioning, it is surely one of the easiest routes to redevelop Rough, so that it is in top-quality condition.
It should also be noted, that Rough is not far from the Aldbrough Gas Storage, which SSE are converting to a second massive hydrogen store.
So Humberside will have two of the largest hydrogen stores in the world, which Centrica and SSE will use to maxise energy security in the wider Humberside and East Yorkshire area, and I suspect to maximise their profits as well.
This video shows the structure of AquaVentus, which is a pipeline system, that the Germans are building to bring much-needed hydrogen to German industry from electrolysers in the North Sea and other countries like Denmark, Norway, the Netherlands and the UK.
I clipped this map from the video.
Note how a branch of AquaVentus makes landfall around the Humber estuary at a UK label.
Will Centrica and SSE be trading hydrogen from Rough and Aldbrough with the Germans through AquaVentus? You bet they will, as the Germans are short of both hydrogen and hydrogen storage.
Guardian To Use Hydrogen In Its Glass Manufacturing
The title of this post, is the same as that of this article on Glass International.
These two paragraphs introduce the application.
Ryze Hydrogen has signed a long-term deal to provide hydrogen to flat glass manufacturer, Guardian Glass
Ryze will supply hydrogen to be used in the manufacture of float glass, which is used in everything from car windscreens and windows in buildings to mirrors and furniture.
This extract from the article explains how the hydrogen is used.
It will be used as a technical gas during the float glass process.
Chris Duguid, Plant Manager from Guardian Glass, said: “We are really pleased to be starting this partnership with Ryze.
“Hydrogen is vital to our float glass production process. Hydrogen is used to create an oxygen-free environment as a blanket to avoid oxidation of the tin onto which we float molten glass.
“As this is needed 24-hours-a-day, seven-days-a-week, 365-days-a-year, it is absolutely critical that we partner with a reliable supplier, which is what we have with Ryze.”
This Wikipedia section, describes the manufacture of float glass.
I’ve never come across a use for hydrogen, where the gas is used for its physical properties and not burned for heat.
How many other applications like this, will the ready availability of hydrogen open up?
I wonder, if the next step will be to use hydrogen to heat the tin and create the actual glass, so that Guardian Glass will be able to make zero-carbon glass.
As the temperatures required are over a 1000 °C, this process could use a lot of hydrogen.
As Guardian Glass are based at Goole, I suspect that they’ll be able to get a hydrogen pipeline from the electrolyser, that SSE are building on Humberside.
3GW Green Hydrogen Project To Power Heavy Industry With Surplus Scottish Wind Energy
The title of this post, is the same as that of this article on the Institute of Mechanical Engineers web site.
I have covered the Kintore Electrolyser before, but this is a professional description of the project from a respected institution, who should know what they are talking about.
I can see several other giant electrolysers being built, in places like Humberside, Merseyside, Teesside, where there are large amounts of wind power and heavy energy users in the cement, chemicals and steel industries.
There could also be one in Norfolk or Suffolk to use the masses of offshore wind power being developed.
‘Czech Sphinx’ Power Plant Intended To Keep Lights On
The title of this post, is the same as that of this article on The Times.
This is the first paragraph.
The businessman known as the “Czech Sphinx” is set to expand his position in Britain’s energy market after securing subsidy contracts to build a new gas-fired power plant and battery storage project.
As I needed to find the answers to particular questions, I looked for and found the original press release on the EP Holdings web site, which is entitled EPH Will Build A New Gas-Fired Power Plant And Battery Storage Facility In The UK At A Cost Of More Than £1 billion.
These statements describe the project.
- It will be a 1700MW high efficiency H-class CCGT power project and a 299MW 2-hour battery storage project
- The power station will be built on the site of the former Eggborough coal station in East Yorkshire.
I find this to be the most significant paragraph.
The high efficiency H-class CCGT project will be the single largest flexible generation asset to be commissioned in the UK since 2012, whilst the battery project will also be one of the largest to be built in the UK to date. Given the site’s close proximity to existing National Grid infrastructure and a number of proposed CCUS and hydrogen pipeline routes, under EPUKI’s plans these projects will make a significant contribution to the UK’s energy transition and security for years to come.
This map from OpenRailwayMap, shows the relationship between the Eggborough site and the nearby Drax power station.
Note.
- The Eggborough power station site is in the South-West corner of the map and is identified by the rail loop. which was used to deliver the coal.
- The Drax power station site is in the North-East corner of the map and is similarly identified by a rail loop.
- There is a high voltage transmission line connecting the two power stations.
- As the crow flies is about eight miles between Eggborough and Drax.
This Google Map shows the Eggborough power station site.
Note.
- The remains of the eight cooling towers are visible at the North of the site.
- The large circular black area in the middle is the coal yard with its rail loop.
- It is a large site.
I have looked in detail at the cleared area in the North-West of the site and the pylons of the connection to Drax are still visible.
So it looks like there is still an electrical connection of some sort to the site.
According to Wikipedia, the original coal-fired power station had a nameplate capacity of 1960 MW, so I suspect that a modernised electricity connection to handle the maximum near 2,000 MW of the new station would be possible.
This map shows the Zero Carbon Humber pipeline layout.
Note.
- The orange line is a proposed carbon dioxide pipeline
- The black line alongside it, is a proposed hydrogen pipeline.
- Drax, Keadby and Saltend are power stations.
- Keadby and Saltend are gas-fired power stations.
- Easington gas terminal is connected to around twenty gas fields in the North Sea.
- The terminal imports natural gas from Norway using the Langeled pipeline.
- The Rough field has been converted to gas storage and can hold four days supply of natural gas for the UK.
- To the North of Hull is the Aldbrough Gas Storage site, which SSE plan to convert to hydrogen storage.
The Eggborough power station site is about eight miles to the South-West of Drax.
I don’t suspect that connecting the Eggborough site to the carbon dioxide, gas and hydrogen pipelines will not be the most challenging of tasks.
So when the press release says.
Given the site’s close proximity to existing National Grid infrastructure and a number of proposed CCUS and hydrogen pipeline routes, under EPUKI’s plans these projects will make a significant contribution to the UK’s energy transition and security for years to come.
The company is not exaggerating.
It appears that carbon dioxide, gas and hydrogen pipelines can be developed and National Grid connections can be reinstated.
Eggborough Will Not Be Alone
From the EP Holdings press release, it appears that the Eggborough power station will be fitted with carbon-capture and will be hydrogen-ready.
This will make it the second power-station in the area to be fitted out in this way, after SSE’s planned Keadby 3, which is described in this page on the SSE web site in this document, which is entitled Keadby 3 Carbon Capture Power Station.
They could also be joined by Keadby Hydrogen power station.
This would mean that zero-carbon power stations in the area could include.
- Eggborough Gas/Hydrogen – 1700 MW
- Eggborough Battery – 299 MW
- Keadby 3 Gas/Hydrogen – 910 MW
- Keadby Hydrogen – 1800 MW – According to this Equinor press release.
Note.
- The Eggborough Battery pushes the total zero-carbon capacity over 4500 MW or 4.5 GW.
- The various Dogger Bank wind farms are to have a total capacity of 8 GW within ten years.
- The various Hornsea wind farms are to have a total capacity of 5.5 GW in a few years.
I would expect that the zero-carbon power stations would make a good fist of making up the shortfall, when the wind isn’t blowing.
Drax, Keadby 1 And Keadby 2 Power Stations
Consider.
- Drax has a nameplate capacity of 3.9 GW, of which 2.6 GW is from biomass and the rest is from coal.
- Keadby 1 has a nameplate capacity of 734 MW.
- Keadby 2 has a nameplate capacity of 734 MW.
How much of this capacity will be fitted with carbon capture, to provide extra zero-carbon backup to the wind farms?
Green Hydrogen From Surplus Wind Power
At times, there will be an excess of renewable energy.
I suspect, an order for a large electrolyser will be placed soon, so that surplus renewable energy can be used to create green hydrogen.
This will be stored in the two storage facilities, that are being developed in the area; Aldbrough and Rough.
Controlling The Fleet
I am by training a Control Engineer and this fleet can be controlled to provide the electricity output required, so that the carbon-dioxide produced is minimised and the cost is at a level to the agreement of producers and users.
Conclusion
It looks like in excess of 20 GW of reliable zero-carbon energy could be available on Humberside.
I’m sure British Steel would like to by a lot of GWhs to make some green steel at Scunthorpe.
Equinor And SSE Eye Green Hydrogen Production For 1.32 GW Dogger Bank D
The title of this post, is the same as that of this article on offshoreWIND.biz.
This is the sub-heading.
SSE Renewables and Equinor, the developers of the Dogger Bank Wind Farm in the UK, are exploring two options for Dogger Bank D, the fourth wind farm the partners are looking to build as part of the development. These include using Dogger Bank D for electricity that would feed into the UK grid and/or for green hydrogen production.
This says to me, that depending on need, electricity from the Dogger Bank Wind Farms and D in particular, can be distributed in the grid or converted into green hydrogen.
- The article says that the electrolyser could become the UK’s largest green hydrogen project
- There will be plenty of hydrogen storage in the salt caverns at Aldbrough, which can currently store the equivalent of 320 GWh of electricity, It is currently being expanded to be one of the largest hydrogen stores in the world according to this page on the SSE web site.
- There are currently two gas-fired power stations at Keadby and they will in a few years be joined by a third, that will be fitted with carbon-capture and a hydrogen-fueled power station.
The various wind farms, power stations and gas storage on Humberside are growing into a very large zero-carbon power cluster, with an output approaching six GW.
Any shortfall in wind output, could be made-up by using the Keadby 3 gas-fired power station with carbon capture or the Keadby hydrogen power station.
Conclusion
Humberside is getting a cluster of power stations and wind farms, that can produce almost twice the electricity of Hinckley Point C nuclear power station.
Increased CCS Can Decarbonise GB Electricity Faster On Route To Net Zero
The title of this post, is the same as that of this news item on the SSE web site.
This is the first paragraph.
Building more power carbon capture and storage plants (Power CCS) could significantly accelerate the UK’s plans to decarbonise the GB electricity system on route to net zero, according to new analysis commissioned by SSE.
I am not surprised, as in my time, I have built several production, storage and distribution mathematical models for products and sometimes bringing things forward has beneficial effects.
These three paragraphs summarise the findings.
The UK Government’s proposed emissions reductions from electricity for 2035 could be accelerated to 2030 by combining its 50GW offshore wind ambition with a significant step up in deployment of Power CCS. This would require 7-9GW (equivalent to 10-12 plants) of Power CCS compared to the current commitment of at least one Power CCS plant mid-decade, according to experts at LCP Delta.
Replacing unabated gas with abated Power CCS generation will deliver significant reductions in greenhouse gas emissions. The analysis suggests that adding 7-9GW Power CCS to the UK’s 2030 offshore wind ambition will save an additional 18 million tonnes of CO2 by 2040, by preventing carbon emissions during periods when the sun isn’t shining, and the wind isn’t blowing.
Gas consumption for electricity generation would not significantly increase, given the 7-9GW Power CCS would displace older and less efficient unabated gas power stations already operating and reduce importing unabated gas generation from abroad via the interconnectors. Importantly, Power CCS can provide a safety net to capture emissions from any gas required to keep the lights on in the event of delays to the roll out of renewables or nuclear.
The report is by LCP Delta, who are consultants based in Edinburgh.
The report says this about the transition to hydrogen.
Power CCS also presents significant opportunities to kickstart, then transition to, a hydrogen economy, benefitting from the synergies between CCS and hydrogen, including proximity to large-scale renewable generation and gas storage facilities which can support the production of both electrolytic and CCS-enabled hydrogen.
And this about the reduction in carbon emissions.
The existing renewables ambition and the accelerated Power CCS ambition are expected to save a total of 72 million tonnes of CO2 by 2040 compared to commitments in the UK’s Net Zero Strategy from October 2021.
I don’t think there’s much wrong with this analysis.
But of course the greens will trash it, as it was paid for by SSE.
I have a few thoughts.
Carbon Capture And Use
I believe we will see a great increase in carbon capture and use.
- Carbon dioxide is already an ingredient to make Quorn.
- Carbon dioxide is needed for fizzy drinks.
- Carbon dioxide can be fed to tomatoes, salad plants, herbs and flowers in giant greenhouses.
- Carbon dioxide can be used to make animal and pet food.
- Carbon dioxide can be used to make building products like plasterboard and blocks.
- Carbon dioxide can be added to concrete.
- Carbon dioxide can be used as a refrigerant and in air-conditioning. There are one or two old Victorian systems still working.
Other uses will be developed.
Carbon Capture Will Get More Efficient
Carbon capture from power stations and boilers, that use natural gas is a relatively new process and its capture will surely get better and more efficient in the next few years.
Gas From INTOG
I explain INTOG in What Is INTOG?.
One of INTOG’s aims, is to supply electricity to the oil and gas rigs and platforms in the sea around the UK.
Currently, these rigs and platforms, use some of the gas they produce, in gas turbines to create the electricity they need.
- I have seen reports that ten percent of the gas that comes out of the ground is used in this way.
- Using the gas as fuel creates more carbon dioxide.
Decarbonisation of our oil and gas rigs and platforms, will obviously be a good thing because of a reduction of the carbon dioxide emitted. but it will also mean that the gas that would have been used to power the platform can be brought ashore to power industry and domestic heating, or be exported to countries who need it.
Gas may not be carbon-neutral, but some gas is more carbon-neutral than others.
SSE’s Plans For New Thermal Power Stations
I have taken this from SSE’s news item.
SSE has deliberately chosen to remain invested in the transition of flexible thermal electricity generation due to the key role it plays in a renewables-led, net zero, electricity system and is committed to decarbonising the generation.
Together with Equinor, SSE Thermal is developing two power stations equipped with carbon capture technology. Keadby 3 Carbon Capture Power Station is based in the Humber, the UK’s most carbon-intensive industrial region, while Peterhead Carbon Capture Power Station is located in the North East of Scotland. Combined, the two stations could capture around three million tonnes of CO2 a year.
Studies have shown that Keadby and Peterhead Carbon Capture Power Stations could make a lifetime contribution of £1.2bn each to the UK economy, creating significant economic opportunity in their respective regions. Both will be vital in supporting the huge amount of renewables which will be coming on the system.
SSE Thermal and Equinor are also collaborating on Keadby Hydrogen Power Station, which could be one of the world’s first 100% hydrogen-fuelled power stations, and Aldbrough Hydrogen Storage, which could be one of the world’s largest hydrogen storage facilities.
Note.
- SSE appear to think that gas-fired power stations with carbon capture are an ideal backup to renewables.
- If gas is available and it can be used to generate electricity without emitting any carbon dioxide, then why not?
- Hydrogen is coming.
Things will get better.
Is A Virtuous Circle Developing?
Consider.
- Spare wind electricity is turned into hydrogen using an electrolyser or perhaps some world-changing electro-chemical process.
- The hydrogen is stored in Aldbrough Hydrogen Storage.
- When the wind isn’t blowing, hydrogen is used to backup the wind in Keadby Hydrogen power station.
- The other Keadby power stations can also kick in using natural gas. The carbon dioxide that they produce, would be captured for storage or use.
- Other users, who need to decarbonise, can be supplied with hydrogen from Aldbrough.
Note.
- Gas turbines are throttleable, so if National Grid wants 600 MW to balance the grid, they can supply it.
- As time progresses, some of the gas-fired power stations at Keadby could be converted to hydrogen.
- Rough gas storage is not far away and could either store natural gas or hydrogen.
- Hydrogen might be imported by tanker from places like Africa and Australia, depending on price.
Humberside will be levelling up and leading the decarbonisation of the UK.
If you have an energy-hungry business, you should seriously look at moving to Humberside.
The Anonymous Widower
