ITM Signs 200MW Electrolyser Deal
The title of this post, is the same as that of this article on renews.biz.
This is the sub-heading.
Agreements with Linde Engineering will be for installation at RWE’s GET H2 Nukleus project in Germany
These paragraphs outline the deal.
ITM Power has signed two contracts for electrolysers, totalling 200MW, which will be installed in green hydrogen plants in Germany that will be supplied by North Sea offshore wind.
The contracts, both with Linde Engineering, are each for 100MW of PEM electrolysers.
The machines will be installed at two plants operated by RWE in Lingen, Germany.
Note.
- Linde Engineering and ITM Power were preselected by RWE for these orders.
- ITM Power seem to be going through scale-up problems.
But the comments in the article and the orders, surely show that ITM Power is now more likely to recover.
Electrolyser System To Linde For Green Hydrogen Production In Niagara Falls, New York
The title of this post, is the same as that of this press release from Cummins.
This is the first paragraph.
Cummins Inc. will supply a 35-megawatt (MW) proton exchange membrane (PEM) electrolyzer system for Linde’s new hydrogen production plant in Niagara Falls, New York. Once commissioned, Cummins’ electrolyzer system will power Linde’s largest green hydrogen plant in the U.S., marking significant progress in moving the green hydrogen economy forward.
Note.
- The electrolyser will be powered by hydroelectricity.
- Linde have a strategic investment in iTM Power, who are a British manufacturer of electrolysers.
- ITM Linde Electrolysis is a joint venture between iTM Power and Linde.
Why did Linde choose Cummins over iTM Power?
Is it down to cost, delivery, politics or quality?
The Concept Of Remote Island Wind
This document from the Department of Business, Industry and Industrial Strategy lists all the Contracts for Difference Allocation Round 4 results for the supply of zero-carbon electricity that were announced yesterday.
The contracts have also introduced a concept that is new to me, called Remote Island Wind. All have got the same strike price of £46.39 per MWh.
Two of the projects on Orkney are community projects of around 30 MW, run by local trusts. This is surely, a model that will work in many places.
There is more on Orkney’s Community Wind Farm Project on this page of the Orkney Islands Council web site.
It could even have an electrolyser to provide hydrogen for zero-carbon fuel, when there is more electricity than is needed. Companies like ITM Power and others already build filling stations with an electrolyser, that can be powered by wind-generated electricity.
The other Remote Island Wind projects are larger with two wind farms of over 200 MW.
It does look to me, that the Department of BEIS is nudging wind farm developers in remote places to a model, that all stakeholders will embrace.
The Viking Wind Farm
I wrote about this wind farm in Shetland’s Viking Wind Farm.
There are more details in this press release from SSE enewables, which is entitled CfD Contract Secured For Viking Energy Wind Farm.
These introductory paragraphs, give a good explanation of the finances of this farm.
SSE Renewables has been successful in the UK’s fourth Contract for Difference (CfD) Allocation Round, announced today, and has secured a low-carbon power contract for 220MW for its wholly-owned Viking Energy Wind Farm (Viking) project, currently being constructed in Shetland.
Viking’s success in securing a contract follows a competitive auction process in Allocation Round 4 (AR4) where it competed within Pot 2 of the allocation round set aside for ‘less established’ technologies including Remote Island Wind.
The 443MW Viking project, which SSE Renewables is currently building in the Shetland Islands, has secured a CfD for 220MW (50% of its total capacity) at a strike price of £46.39/MWh for the 2026/27 delivery year.
The successful project will receive its guaranteed strike price, set on 2012 prices but annually indexed for CPI inflation, for the contracted low carbon electricity it will generate for a 15-year period. Securing a CfD for Viking stabilises the revenue from the project whilst also delivering price security for bill payers.
It’s very professional and open to explain the capacity, the contract and the finances in detail.
The press release also has this paragraph, which details progress.
Viking is progressing through construction with over 50 per cent of turbine foundation bases poured. When complete in 2024, Viking Energy Wind Farm will be the UK’s most productive onshore wind farm in terms of annual electricity output, with the project also contributing to Shetland’s security of supply by underpinning the HVDC transmission link that will connect the islands to the mainland for the first time.
SSE also released this press release, which is entitled Major Milestone Reached As First Subsea Cable Installation Begins On Shetland HVDC Link, where this is the first paragraph.
The first phase of cable laying as part of the SSEN Transmission Shetland High-Voltage Direct Current (HVDC) Link began this week off the coast of Caithness, marking a major milestone in the £660M project.
SSE seem to be advancing on all fronts on the two projects!
The Stornoway Wind Farm
This press release from EDF Renewables is entitled EDF Renewables UK Welcomes Contract for Difference Success, where these are the first two paragraphs.
Two EDF Renewables UK projects bid into the Contract for Difference (CfD) auction round held by the UK Government’s BEIS department have been successful.
The projects are the Stornoway wind farm on the Isle of Lewis and Stranoch wind farm in Dumfries and Galloway. Together these onshore wind farms will provide 300 MW of low carbon electricity which is an important contribution to reaching net zero.
The press release also gives this information about the contract and completion of the Stornoway wind farm.
Stornoway Wind Farm on the Isle of Lewis is a joint venture with Wood. The project has won a CfD for 200 MW capacity, the strike price was £46.39, the target commissioning date is 31 March 2027.
This page on the Lewis Wind Power web site, gives these details of the Stornoway Wind Farm.
The Stornoway Wind Farm would be located to the west of the town of Stornoway in an area close to the three existing wind farm sites.
The project has planning consent for up to 36 turbines and is sited on land owned by the Stornoway Trust, a publicly elected body which manages the Stornoway Trust Estate on behalf of the local community.
The local community stands to benefit as follows:
- Community benefit payments currently estimated at £900,000 per annum, which would go to an independent trust to distribute to local projects and organisations
- Annual rental payments to local crofters and the Stornoway Trust – which we estimate could total more than £1.3m, depending on the CfD Strike Price secured and the wind farm’s energy output
- Stornoway Wind Farm is the largest of the three consented wind farm projects with a grid connection in place and is therefore key to the needs case for a new grid connection with the mainland. Indeed, the UK energy regulator Ofgem has stated that it will support the delivery of a new 450MW cable if the Stornoway and Uisenis projects are successful in this year’s Contract for Difference allocation round.
Note the last point, where only the Stornoway wind farm was successful.
The Uisenis Wind Farm
This press release from EDF Energy is entitled Lewis Wind Power Buys Uisenis Wind Farm, gives these details of the sale.
Lewis Wind Power (LWP), a joint venture between Amec Foster Wheeler and EDF Energy Renewables has bought the Uisenis Wind Farm project on the Isle of Lewis. The wind farm has planning consent for the development of 45 turbines with a maximum capacity of 162 MW. This would be enough to power 124,000 homes and would be the biggest renewable energy development on the Western Isles.
LWP owns the Stornoway Wind Farm project located around 20km to the north of Uisenis which has planning consent to develop 36 turbines to a maximum capacity of 180 MW – enough to power 135,000 homes.
This would bring Stornoway and Uisenis wind farms under the similar ownership structures.
This is a significant paragraph in the press release.
On behalf of Eishken Limited, the owner of the site where the Uisenis Wind Farm will be located, Nick Oppenheim said: “I am delighted that LWP are taking forward the wind farm. The resources available on the Eishken estate, and the Western Isles in general, means that it is an excellent location for renewable energy projects and, as such, the company is also developing a 300MW pumped storage hydro project immediately adjacent to the Uisenis wind farm. With such potential for renewables and the positive effect they will have on the local community, economy, and the UK as a whole I am are looking forward to positive news on both support for remote island projects and the interconnector.”
Note the mention of pumped storage.
This article on the BBC is entitled Pumped Storage Hydro Scheme Planned For Lewis, where this paragraph introduces the scheme.
A pumped storage hydro scheme using sea water rather than the usual method of drawing on freshwater from inland lochs has been proposed for Lewis.
The only other information is that it will provide 300 MW of power, but nothing is said about the storage capacity.
It looks like Lewis will have a world-class power system.
Mossy Hill And Beaw Field Wind Farms
Mossy Hill near Lerwick and Beaw Field in Yell are two Shetland wind farms being developed by Peel L & P.
This press release from Peel L & P is entitled Government Support For Two Shetland Wind Farms, where these are the first two paragraphs.
Plans for two onshore wind farms on the Shetland Islands which would help meet Scotland’s targets for renewable energy production are a step closer to being delivered after receiving long-term Government support.
Clean energy specialists Peel NRE has been successful in two bids in the Department for Business, Energy and Industrial Strategy’s (BEIS) Contracts for Difference (CfD) scheme; one for its Mossy Hill wind farm near Lerwick and the other for Beaw Field wind farm in Yell.
It looks like the two wind farms will power 130,000 houses and are planned to be operational in 2027.
Conclusion
I must admit that I like the concept. Especially, when like some of the schemes, when it is linked to community involvement and improvement.
Only time will tell, if the concept of Remote Island Wind works well.
Shell To Start Building Europe’s Largest Renewable Hydrogen Plant
The title of this post, is the same as that of this press release from Shell.
This is the first paragraph.
Shell Nederland B.V. and Shell Overseas Investments B.V., subsidiaries of Shell plc, have taken the final investment decision to build Holland Hydrogen I, which will be Europe’s largest renewable hydrogen plant once operational in 2025.
Theconstruction timeline for Holland Hydrogen 1 is not a long one.
The next paragraph describes the size and hydrogen production capacity.
The 200MW electrolyser will be constructed on the Tweede Maasvlakte in the port of Rotterdam and will produce up to 60,000 kilograms of renewable hydrogen per day.
200 MW is large!
The next paragraph details the source of the power.
The renewable power for the electrolyser will come from the offshore wind farm Hollandse Kust (noord), which is partly owned by Shell.
These are my thoughts.
Refhyne
Refhyne is a joint project between Shell and ITM Power, with backing from the European Commission, that has created a 10 MW electrolyser in Cologne.
The 1300 tonnes of hydrogen produced by this plant will be integrated into refinery processes.
Refhyne seems to have been very much a prototype for Holland Hydrogen 1.
World’s Largest Green Hydrogen Project – With 100MW Electrolyser – Set To Be Built In Egypt
The sub-title is the title, of this article on Recharge.
It looks like Holland Hydrogen 1, is double the current largest plant under construction.
Shell is certainly going large!
Will ITM Power Be Working Again With Shell?
Refhyne has probably given Shell a large knowledge base about ITM Power’s electrolysers.
But Refhyne is only 10 MW and Holland Hydrogen 1 is twenty times that size.
This press release from ITM Power is entitled UK Government Award £9.3 m For Gigastack Testing.
This is the first paragraph.
ITM Power (AIM: ITM), the energy storage and clean fuel company, announces that the Company has been awarded a contract by The Department for Business, Energy and Industrial Strategy (BEIS), under its Net Zero Innovation Portfolio Low Carbon Hydrogen Supply 2 Competition, to accelerate the commercial deployment of ITM Power’s 5 MW Gigastack platform and its manufacture. The award for the Gigatest project is for £9.3m and follows initial designs developed through previous BEIS funding competitions.
Note.
- The Gigastack is 2.5 times bigger, than ITM Power’s previously largest electrolyser.
- Forty working in parallel, in much the same way that the ancient Egyptians built the pyramids, will be needed for Holland Hydrogen 1.
- ITM Power have the world’s largest electrolyser factory, with a capacity of one GW. They have plans to create a second factory.
ITM Power would probably be Shell’s low-risk choice.
My company dealt with Shell a lot in the 1970s, with respect to project management software and we felt, that if Shell liked you, they kept giving you orders.
The Hollandse Kust Noord Wind Farm
This wind farm is well described on its web site, where this is the introduction on the home page.
CrossWind, a joint-venture between Shell and Eneco, develops and will operate the Hollandse Kust Noord subsidy-free offshore wind project.
Hollandse Kust Noord is located 18.5 kilometers off the west coast of the Netherlands near the town of Egmond aan Zee.
CrossWind plans to have Hollandse Kust Noord operational in 2023 with an installed capacity of 759 MW, generating at least 3.3 TWh per year.
This Google Map shows the location of Egmond aan Zee.
Note that the red arrow points to Egmond aan Zee.
Will The Electrolyser Be Operational In 2025?
If Shell choose ITM Power to deliver the electrolysers, I don’t think Shell are being that ambitious.
I would suspect that connecting up an electrolyser is not the most complicated of construction tasks.
- Build the foundations.
- Fix the electrolyser in place.
- Connect power to one end.
- Connect gas pipes to the other.
- Switch on and test.
Note.
- If ITM Power deliver electrolysers that work, then the installation is the sort of task performed on chemical plants all over the world.
- ITM Power appear to have tapped the UK Government for money to fund thorough testing of the 5 MW Gigastack electrolyser.
- Enough wind power from Hollandse Kust Noord, should be generated by 2025.
I feel it is very much a low risk project.
Shell’s Offshore Electrolyser Feasibility Study
This is mentioned in this article in The Times, which describes Holland Hydrogen 1, where this is said.
Shell is also still involved in a feasibility study to deploy electrolysers offshore alongside the offshore wind farm. It has suggested this could enable more efficient use of cabling infrastructure.
I very much feel this is the way to go.
Postscript
I found this article on the Dutch Government web site, which is entitled Speech By Prime Minister Mark Rutte At An Event Announcing The Construction Of Holland Hydrogen 1.
This is an extract.
By building Holland Hydrogen 1, Shell will give the Dutch hydrogen market a real boost.
So congratulations are in order.
And this is only the beginning.
Because countless companies and knowledge institutions are working now to generate the hydrogen economy of tomorrow.
The government is supporting this process by investing in infrastructure, and by granting subsidies.
Because we want to achieve our climate goals, though the war in Ukraine won’t make it any easier.
We want to reduce our dependence on Russian gas.
We want the Netherlands to lead the way in the European energy transition.
And all these ambitions are combined in the Holland Hydrogen 1 project.
Mark Rutte seems to believe in hydrogen.
Conclusion
This is a very good example of the sort of large electrolyser, we’ll be seeing all over the world.
In fact, if this one works well, how many 200 MW electrolysers will Shell need all over the world?
Will they all be identical?
New Mobile Hydrogen Unit Unveiled By Logan Energy In Bid To Accelerate Greener Transport
The title of this post, is the same as that of this article on Fuel Cell Works.
This sums up the development, that has been unveiled by Logan Energy.
It is a compression trailer, that looks like it could be towed by any vehicle capable of towing a horse box.
- The compressor can transfer hydrogen between any two cylinders at all the usual pressures.
- It is aimed at both the bus and heavy goods vehicle market.
- The hydrogen capacity of the trailer is not stated.
I feel that this sort of development will help operators embrace hydrogen.
A bus company for instance could have an appropriate number of trailers, for their fleet of hydrogen buses.
- The bus company would need a suitable towing vehicle, like a light truck.
- Trailers would be filled at an electrolyser outside of the city.
- Each bus depot could have a space, where a trailer could be parked to fill the buses.
- A schedule would probably need to be developed for filling the trailers.
We will see more developments like this.
But they will have to compete with companies like ITM Power, who can supply on-site electrolysers.
West Midlands To Run ‘Largest Hydrogen Bus Fleet’ Due To New Funding
The title of this post, is the same as that of this article on the BBC.
These are a few points from the article.
- The region is set to get 124 new hydrogen vehicles.
- The West Midlands is set to run the UK’s largest hydrogen bus fleet after securing new funding.
- The region will get 124 new buses after it won £30m from the Department for Transport to fund a switchover.
- Twenty four of the new vehicles will be articulated tram-style buses set to run on a new bus priority route between Walsall, Birmingham and Solihull.
Does the last statement mean, that they will buying a hundred double-decker hydrogen buses?
A few thoughts.
Riding Birmingham’s New Hydrogen-Powered Buses
These are a few pictures from Riding Birmingham’s New Hydrogen-Powered Buses.
They were excellent buses from Wrightbus.
The Tram Style Buses
The Belgian firm; Van Hool have a product called Exquicity. This video shows them working in Pau in France.
These tram buses run on rubber types and are powered by hydrogen.
Similar buses running in Belfast are diesel-electric.
Could these be what the article refers to as tram-style buses?
It should be noted, that the West Midlands and Pau have bought their hydrogen filling stations from ITM Power in Sheffield.
So has there has been a spot of the Entente Cordiale between Pau and the West Midlands?
Will The West Midlands Buy The Other Hundred Buses From Wrightbus?
There doesn’t seem to be any problems on the web about the initial fleet, so I suspect they will.
It should also be noted that Wrightbus make the following types of zero-emission buses.
- StreetDeck – Hydroliner FCEV – Double-deck hydrogen bus
- StreetDeck – Electroliner BEV – Double-deck battery bus
- GB Kite – Hydroliner FCEV – Single-deck hydrogen bus
- GB Kite – Electroliner BEV – Single-deck battery bus
These would surely enable the West Midlands to mic-and-match according to their needs.
Norfolk Wind Farms Offer ‘Significant Benefit’ For Local Economy
The title of this post, is the same as that of this article on the BBC.
This is a comprehensive article, which looks at the benefits of the huge Norfolk Boreas and Norfolk Vanguard wind farms will have to the economy of Norfolk.
The last section is devoted to Norfolk Nimby; Raymond Pearce.
This is the section.
Following the re-approval of the decision by the government, Mr Pearce says he is considering a new appeal over what he calls “a very poor decision”.
He is also sceptical of claims the two new wind farms will bring the economic gains promised by Vattenfall.
“It’s renewable energy at any cost and the cost here is to the environment in Norfolk,” he says.
“I don’t blame them for being positive about it, it’s their industry but they’re not looking at it holistically.”
He says he is not against renewable energy but thinks a better plan is needed to connect the offshore windfarms and minimise the number of cables and substations onshore.
It’s his money if he appeals, but we do need more wind, solar and other zero-carbon energy to combat global warming and its effects like the encroachment of the sea around Norfolk.
I believe, that building wind farms off the coast of Essex, Suffolk and Norfolk is a good move, as in the future, if we have spare electricity, it will be easy to export energy to Europe, through existing interconnectors.
But I do agree with him, that a better plan is needed to connect the offshore windfarms and minimise the number of cables and substations onshore.
A Norfolk Powerhouse
This map from Vattenfall, the developer of the two wind farms, shows the position of the farms and the route of the cable to the shore.
Note.
- The purple line appears to be the UK’s ten mile limit.
- Norfolk Boreas is outlined in blue.
- Norfolk Vanguard is outlined in orange.
- Cables will be run in the grey areas.
- Both wind farms are planned to have a capacity of 1.8 GW
Landfall will be just a few miles to the South of the Bacton gas terminal.
Bacton Gas Terminal
Bacton gas terminal is much more than a simple gas terminal.
- It is a complex of six gas terminals on four sites.
- There is a National Grid terminal, that odourises and blends the gas before distributing it into the National Transmission System via five outgoing 36-inch feeders to much of Southern England.
- There is a gas interconnector to Belgium.
- There is a gas interconnector to The Netherlands.
- There is coastal erosion in the area.
With the need to decarbonise, I can’t help feeling that the Bacton gas terminal is very much on the decline and the site will need to be repurposed in the next few years.
Blending Hydrogen With Natural Gas
If you blend a proportion of hydrogen into natural gas, this has two beneficial effects.
- Gas used in domestic and industrial situations will emit less carbon dioxide.
- In the near future we will be replacing imported natural gas with hydrogen.
The hydrogen could be produced by a giant electrolyser at Bacton powered by the electricity from the two Norfolk wind farms.
At the present time, a research project call HyDeploy is underway, which is investigating the blending of hydrogen into the natural gas supply.
- Partners include Cadent, Northern Gas Networks, the Health and Safety Executive, Keele University and ITM Power and Progessive Energy.
- A first trial at Keele University has been hailed as a success.
- It showed up to twenty percent of hydrogen by volume can be added to the gas network without the need to change any appliances or boilers.
Larger trials are now underway.
A Giant Electrolyser At Bacton
If hydrogen were to be produced at Bacton by a giant electrolyser, it could be used or distributed in one of the following ways.
- Blended with natural gas for gas customers in Southern England.
- Stored in a depleted gas field off the coast at Bacton. Both Baird and Deborah gas fields have been or are being converted to gas storage facilities, connected to Bacton.
- Distributed by truck to hydrogen filling stations and bus and truck garages.
- Greater Anglia might like a hydrogen feed to convert their Class 755 trains to hydrogen power.
- Sent by a short pipeline to the Port of Great Yarmouth and possibly the Port of Lowestoft.
- Exported to Europe, through one of the interconnectors.
Note.
- If the electrolyser were to be able to handle the 3.6 GW of the two wind farms, it would be the largest in the world.
- The size of the electrolyser could be increased over a few years to match the output of the wind farms as more turbines are installed offshore.
- There is no reason, why the electrical connection between Bacton and the landfall of the wind farm cable couldn’t be offshore.
If ITM Power were to supply the electrolyser, it would be built in the largest electrolyser factory in the World, which is in Sheffield in Yorkshire.
A Rail Connection To The Bacton Gas Terminal
This Google Map shows the area between North Walsham and the coast.
Note.
- North Walsham is in the South-Western corner of the map.
- North Walsham station on the Bittern Line is indicated by the red icon.
- The Bacton gas terminal is the trapezoidal-shaped area on the coast, at the top of the map.
I believe it would be possible to build a small rail terminal in the area with a short pipeline connection to Bacton, so that hydrogen could be distributed by train.
How Much Hydrogen Could Be Created By The Norfolk Wind Farms?
In The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid, I said the following.
Ryze Hydrogen are building the Herne Bay electrolyser.
- It will consume 23 MW of solar and wind power.
- It will produce ten tonnes of hydrogen per day.
The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.
Each of the Norfolk wind farms, if they were working flat out would produce 43.2 GWh of electricity in a day.
Dividing the two figures gives a daily production rate of 782.6 tonnes of hydrogen per day.
But what happens if the wind doesn’t blow?
This is where the gas storage in the Baird, Deborah and other depleted gas fields comes in.In times of maximum wind, hydrogen is stored for use when the wind doesn’t blow.
Conclusion
I believe a plan like this, would be much better for Norfolk, the UK and the whole planet.
Using the existing gas network to carry the energy away from Norfolk, could mean that the electricity connection across Norfolk could be scaled back.
The Mathematics Of Blending Twenty Percent Of Hydrogen Into The UK Gas Grid
HyDeploy is a project, that is investigating blending hydrogen into the UK’s natural gas supply to reduce the amount of carbon dioxide produced by the burning of natural gas in power stations, industrial processes and in our homes and other buildings.
To find out more about the project, visit the HyDeploy web site.
This is a paragraph from this page on the HyDeploy web site, which describes the current progress of the project.
HyDeploy is progressing well. The HSE gave the go ahead for a live demonstration, at Keele University, of blended hydrogen and natural gas which began in Autumn 2019 and completed in Spring 2021. The HSE are satisfied that the blend of gas will be as safe as the gas we all currently use. The hydrogen content will be up to 20% and has so far reached 15%.
Note that HSE is the Health and Safety Executive, who are closely involved.
HyDeploy has now moved on to Phase 2 in the North East.
For our North East demonstration, we have contacted everyone who will be involved in that demonstration – more than 650 homes – and arranged for our engineers to carry out Gas Safe checks on their gas appliances and gather information on the range of appliances in the demonstration area. The Gas Safe checks were free of charge. Almost 90% of those homes have engaged with us.
What would be the effects of 20 % of hydrogen blended into natural gas?
Will current boilers, cookers and other gas-powered devices work on a blend of hydrogen and natural gas?
This is one for the scientists and it is one of the objectives of the HyDeploy trial to understand how every use of gas performs if instead of natural gas, the fuel is a mixture of eighty percent natural gas and twenty percent hydrogen.
I will assume that these problems are solvable.
I am not just hoping, but I can remember in the early 1970s, when our elderly gas cooker was successfully converted from town gas, which was typically a mixture of hydrogen (50%), methane (35%),carbon monoxide (10 %) and ethylene (5%), to natural gas, as North Sea gas started to flow.
This document from the UK government is entitled Fuels: Natural Gas, which contains a section entitled Material Properties Relevant To Use, where this is said.
Natural gas is a combustible gas that is a mixture of simple hydrocarbon compounds. It contains primarily methane, along with small amounts of ethane, butane, pentane, and propane. Natural gas does not contain carbon monoxide. The by-products of burning natural gas are primarily carbon dioxide and water vapour. Natural gas is colourless, tasteless and odourless. Because it is odourless, an odorant (80% tertiarybutyl mercaptan, 20% dimethyl sulphide) is added to the gas, to give the gas a distinctive smell. Other beneficial properties of natural gas are a high ignition temperature and a
narrow flammability range, meaning natural gas will ignite at temperatures above 593°degrees and burn at a mix of 4 – 15% volume in air (St. Lawrence Gas, 2015)
As ethane (C2H6), butane (C4H10), pentane (C5H12) and propane (C3H8) are all similar simple hydrocarbons to methane, which burn to produce carbon dioxide and water, I will assume in this analysis, that natural gas is all methane (CH4).
It is reasonable to assume, that currently we use a fuel which is equivalent to 100 % methane and that in the future we could use 80 % methane and 20 % hydrogen. Also in the past, we used to use a fuel, that was 50 % hydrogen and 35 % methane. The carbon monoxide is a poison, so I’ll ignore it, but ethylene (C2H4) is another of those simple hydrocarbons, which burn to release just carbon dioxide and water.
So if we were able to go from town to natural gas fifty years ago, by just adjusting gas equipment, surely we can go partly the other way in the Twenty-First Century.
I can certainly see the UK gas supply containing twenty percent hydrogen, but wouldn’t be surprised to see a higher level of hydrogen in the future.
How Much Hydrogen Needs To Be Added?
This page on worldodometer says this about UK gas consumption.
The United Kingdom consumes 2,795,569 million cubic feet (MMcf) of natural gas per year as of the year 2017.
I will now calculate the weight of hydrogen needed to be added.
- 2,795,569 million cubic feet converts to 79161.69851 million cubic metres.
- I will round that to 79161.7 million cubic metres.
- Twenty percent is 15832.34 million cubic metres.
- A cubic metre of hydrogen weighs 0.082 Kg, which gives that in a year 1,298.25188 million kilograms will need to be added to the UK gas supply.
This is 1,298,251.88 tonnes per year, 3,556.85 tonnes per day or 148.2 tonnes per hour.
How Much Electricity Is Needed To Create This Amount Of Hydrogen?
In Can The UK Have A Capacity To Create Five GW Of Green Hydrogen?, I said the following.
Ryze Hydrogen are building the Herne Bay electrolyser.
- It will consume 23 MW of solar and wind power.
- It will produce ten tonnes of hydrogen per day.
The electrolyser will consume 552 MWh to produce ten tonnes of hydrogen, so creating one tonne of hydrogen needs 55.2 MWh of electricity.
To create 148.2 tonnes per hour of hydrogen would need 8,180.64 MW of electricity or just under 8.2 GW.
How Much Carbon Dioxide Would Be Saved?
This page on the Engineering Toolbox is entitled Combustion Of Fuels – Carbon Dioxide Emission and it gives a list of how much carbon dioxide is emitted, when a fuel is burned.
For each Kg of these fuels, the following Kg of carbon dioxide will be released on combustion.
- Methane – 2.75
- Gasoline – 3.30
- Kerosene – 3.00
- Diesel – 3.15
- Bituminous coal – 2.38
- Lignite 1.10
- Wood – 1.83
Engineering Toolbox seems a very useful web site.
I will now calculate how much carbon dioxide would be saved.
- In 2017, UK methane consumption was 79161.7 million cubic metres.
- One cubic metre of methane weighs 0.554 Kg.
- The total weight of methane used is 43,855,581.8 tonnes.
- Multiplying by 2.75 shows that 120,602,849.95 tonnes of carbon dioxide will be produced.
As twenty percent will be replaced by hydrogen, carbon dioxide emission savings will be 24,120,569.99 tonnes.
That seems a good saving, from a small country like the UK.
The UK would also reduce natural gas consumption by twenty percent or 15832.34 million cubic metres per year.
How many other countries with good renewable and zero-carbon electricity resources like Australia, Chile, Denmark, France, Iceland, Ireland, Jordan, Morocco, Norway, Sweden and the United States will take this route, as it seems a good way to save large amounts of carbon?
There is also the collateral benefit, that countries with a good supply of hydrogen can use hydrogen to decarbonise the heavy transport sectors of rail, road and sea freight transport.
The big winners would appear to be those companies like ITM Power, who manufacture electrolysers and those companies like Fortescue Future Industries, who are prospecting, developing and promoting the hydrogen resources of the planet.
The losers will be countries, who are reliant on importing large amounts of gas and other fossil fuels, who don’t have access to large amounts of renewable energy like geothermal, hydro, nuclear, solar and wind.
Germany’s energy policy of no nuclear, more coal and Russian gas seems to have been a mistake.
But I’m sure, if Olaf Sholz talked nicely to Boris, there is a deal to be made.
- German utilities have already arranged to fund BP’s move into wind farms in Morecambe Bay and the North Sea.
- Norfolk’s gas terminal at Bacton is less than three hundred miles from Germany’s new hydrogen terminal at Wilhelmshaven.
The biggest loser could be Vlad the Poisoner.
Is There A Need For A Norfolk-Suffolk Interconnector?
The coast of East Anglia from the Wash to the Haven Ports of Felixstowe, Harwich and Ipswich is becoming the Energy Coast of England.
Starting at the Wash and going East and then South, the following energy-related sites or large energy users are passed.
Bicker Fen Substation
Bicker may only be a small hamlet in Lincolnshire, but it is becoming increasingly important in supplying energy to the UK.
Nearby is Bicker Fen substation, which connects or will connect the following to the National Grid.
- The 26 MW Bicker Fen onshore windfarm.
- The 1,400 MW interconnector from Denmark called Viking Link.
- The proposed 857 MW offshore wind farm Triton Knoll.
This Google Map shows the location of Bicker Fen with respect to The Wash.
Bicker Fen is marked by the red arrow.
The Google Map shows the substation.
It must be sized to handle over 2 GW, but is it large enough?
Dudgeon Offshore Wind Farm
The Dudgeon offshore wind farm is a 402 MW wind farm, which is twenty miles off the North Norfolk coast.
- It has 67 turbines and an offshore substation.
- It is connected to the shore at Weybourne on the coast from where an underground cable is connected to the National Grid at Necton.
- It became operational in Oct 2017.
- Equinor and Statkraft are part owners of the windfarm and this is the home page of the wind farm’s web site.
- Equinor is the operator of the wind farm.
This Google Map shows the location of Weybourne on the coast.
Note.
- Weybourne is in the middle on the coast.
- Sheringham is on the coast in the East.
- Holt is on the Southern edge of the map almost South of Weybourne.
This second map shows the location of the onshore substation at Necton, with respect to the coast.
Note.
- The Necton substation is marked by a red arrow.
- Holt and Sheringham can be picked out by the coast in the middle.
- Weybourne is to the West of Sheringham.
- Necton and Weybourne are 35 miles apart.
Digging in the underground cable between Necton and Weybourne might have caused some disruption.
Looking at Weybourne in detail, I can’t find anything that looks like a substation. So is the Necton substation connected directly to Dudgeon’s offshore substation?
Sheringham Shoal Offshore Wind Farm
The Sheringham Shoal offshore wind farm is a 316.8 MW wind farm, which is eleven miles off the North Norfolk coast.
- It has 88 turbines and two offshore substations.
- As with Dudgeon, it is connected to the shore at Weybourne on the coast.
- But the underground cable is connected to an onshore substation at Salle and that is connected to the National Grid at Norwich.
- It became operational in Sept 2012.
- Equinor and Statkraft are part owners of the windfarm and this is the home page of the wind farm’s web site.
- Equinor is the operator of the wind farm.
This second map shows the location of the onshore substation at Salle, with respect to the coast.
Note.
- The Salle substation is marked by a red arrow.
- Holt, Weybourne and Sheringham can be picked out by the coast in the middle.
- Weybourne is to the West of Sheringham.
- Salle and Weybourne are 13.5 miles apart.
Could the following two statements be true?
- As the Sheringham Shoal wind farm was built first, that wind farm was able to use the shorter route.
- It wasn’t built large enough to be able to handle the Dudgeon wind farm.
The statements would certainly explain, why Dudgeon used a second cable.
Extending The Dudgeon And Sheringham Shoal Wind Farms
Both the Dudgeon And Sheringham Shoal web sites have details of the proposed join extension of both wind farms.
This is the main statement on the Overview page.
Equinor has been awarded an Agreement for Lease by the Crown Estate, the intention being to seek consents to increase the generating capacity of both the Sheringham Shoal Offshore Wind Farm and the Dudgeon Offshore Wind Farm.
They then make three points about the development.
- Equinor is proposing a joint development of the two projects with a common transmission infrastructure.
- As part of the common DCO application, the Extension Projects have a shared point of connection at the National Grid Norwich Main substation.
- These extension projects will have a combined generating capacity of 719MW which will make an important contribution to the UK’s target of 30GW of electricity generated by offshore wind by 2030.
This statement on the Offshore Location page, describes the layout of the wind farms.
The Sheringham Shoal Offshore Wind Farm extension is to the north and the east of the existing wind farm, while its Dudgeon counterpart is to the north and south east of the existing Dudgeon Offshore Wind Farm site. The proposed extension areas share the boundaries with its existing wind farm site.
They then make these two important points about the development.
- Equinor is seeking to develop the extension project with a joint transmission infrastructure. A common offshore substation infrastructure is planned to be located in the Sheringham Shoal wind farm site.
- The seabed export cable which will transmit the power generated by both wind farm extensions will make landfall at Weybourne.
There is also this map.
Note.
- The purple line appears to be the UK’s ten mile limit.
- The Sheringham Shoal Extension is outlined in red.
- The Dudgeon Extension is outlined in blue.
- The black lines appear to be the power cables.
I suspect the dotted blue lines are shipping routes sneaking their way through the turbines.
This statement on the Onshore Location page, describes the layout of the offshore and onshore cables.
A new seabed export cable will bring the electricity generated by both the Sheringham Shoal and Dudgeon Offshore Wind Farm extensions to shore at Weybourne, on the coast of Norfolk.
They then make these two important points about the development.
- From there a new underground cable will be installed to transmit that power to a new purpose built onshore substation, which will be located within a 3km radius of the existing Norwich main substation, south of Norwich. This will be the National Grid network connection point for the electricity from both wind farm extensions.
- The power will be transmitted from landfall to the substation using an HVAC system which eliminates the need for any relay stations along the onshore cable route.
There is also this map.
It will be a substantial undertaking to build the underground cable between Weybourne and South of Norwich.
Bacton Gas Terminal
The Bacton gas terminal is a complex of six gas terminals about ten miles East of Cromer.
- It lands and processes gas from a number of fields in the North Sea.
- It hosts the UK end of the BBL pipeline to The Netherlands.
- It hosts the UK end of the Interconnector to Zeebrugge in Belgium.
- The Baird and Deborah fields, which have been developed as gas storage, are connected to the gas terminal. They are both mothballed.
This Google Map shows the location of the terminal.
Note.
- The Bacton gas terminal is marked by a red arrow.
- Sheringham is in the North West corner of the map.
- Cromer, Overstrand, Trimingham and Mundesley are resort towns and villages along the coast North of Bacton.
This second map shows the Bacton gas terminal in more detail.

Norfolk Boreas And Norfolk Vanguard
Norfolk Boreas and Norfolk Vanguard are two wind farms under development by Vattenfall.
- Norfolk Boreas is a proposed 1.8 GW wind farm, that will be 45 miles offshore.
- Norfolk Vanguard is a proposed 1.8 GW wind farm, that will be 29 miles offshore.
This map shows the two fields in relation to the coast.
Note.
- The purple line appears to be the UK’s ten mile limit.
- Norfolk Boreas is outlined in blue.
- Norfolk Vsnguard is outlined in orange.
- Cables will be run in the grey areas.
This second map shows the onshore cable.
Note.
- The cables are planned to come ashore between Happisburgh and Eccles-on-Sea.
- Bacton gas terminal is only a short distance up the coast.
- The onshore cable is planned to go from here across Norfolk to the Necton substation.
But all of this has been overturned by a legal ruling.
This article on the BBC is entitled Norfolk Vanguard: Ministers Wrong Over Wind Farm Go-Ahead, Says Judge.
These are the first four paragraphs.
A High Court judge has quashed permission for one of the world’s largest offshore wind farms to be built off the east coast of England.
The Norfolk Vanguard Offshore Wind Farm was granted development consent in July by the Secretary of State for Business, Energy and Industrial Strategy (BEIS).
But Mr Justice Holgate overturned the decision following legal action from a man living near a planned cable route.
A Department for BEIS spokeswoman said it was “disappointed by the outcome”.
I bet the spokeswoman was disappointed.
Vattenfall and the BEIS will go back to the drawing board.
But seriously, is it a good idea to dig an underground cable all the way across Norfolk or in these times build a massive overhead cable either?
Perhaps the solution is to connect the Norfolk Boreas And Norfolk Vanguard wind farms to a giant electrolyser at Bacton, which creates hydrogen.
- The underground electricity cable across Norfolk would not be needed.
- Bacton gas terminal is only a few miles up the coast from the cable’s landfall.
- The UK gets another supply of gas.
- The hydrogen is blended with natural gas for consumption in the UK or Europe.
- A pure hydrogen feed can be used to supply hydrogen buses, trucks and other vehicles, either by tanker or pipeline.
- Excess hydrogen could be stored in depleted gas fields.
The main benefit though, would be that it would transform Bacton gas terminal from a declining asset into Norfolk’s Hydrogen Powerhouse.
Great Yarmouth And Lowestoft
Great Yarmouth Outer Harbour and the Port of Lowestoft have not been the most successful of ports in recent years, but with the building of large numbers of wind farms, they are both likely to receive collateral benefits.
I wouldn’t be surprised to see the support ships for the wind farms switching to zero-carbon power, which would require good electrical connections to the ports to either charge batteries or power electrolysers to generate hydrogen.
Sizewell
Sizewell has only one nuclear power station at present; Sizewell B, but it could be joined by Sizewell C or a fleet of Small Modular Reactors (SMR).
The Sizewell Overhead Transmission Line
Sizewell also has a very high capacity overhead power line to Ipswich and the West.
I doubt, it would be possible to build an overhead transmission line like this today.
Sizewell And Hydrogen
EdF, who own the site are involved with Freeport East and may choose to build a large electrolyser in the area to create hydrogen for the Freeport.
East Anglia Array
The East Anglia Array will be an enormous wind farm., comprising up to six separate projects.
It will be thirty miles offshore.
It could generate up to 7.2 GW.
The first project East Anglia One is in operation and delivers 714 MW to a substation in the Deben Estuary, which connects to the Sizewell high-capacity overhead power line.
Most projects will be in operation by 2026.
Freeport East
As the Freeport develops, it will surely be a massive user of both electricity and hydrogen.
Problems With The Current Electricity Network
I don’t believe that the current electricity network, that serves the wind farms and the large energy users has been designed with the number of wind farms we are seeing in the North Sea in mind.
Every new windfarm seems to need a new connection across Norfolk or Suffolk and in Norfolk, where no high-capacity cables exist, this is stirring up the locals.
There is also no energy storage in the current electricity network, so at times, the network must be less than efficient and wind turbines have to be shut down.
Objections To The Current Policies
It is not difficult to find stories on the Internet about objections to the current policies of building large numbers of wind farms and the Sizewell C nuclear power station.
This article on the East Anglia Daily Times, which is entitled Campaigners Unite In Calling For A Pause Before ‘Onslaught’ Of Energy Projects ‘Devastates’ Region is typical.
This is the first paragraph.
Campaigners and politicians have called on the Government to pause the expansion of the energy industry in Suffolk, which they fear will turn the countryside into an “industrial wasteland” and hit tourism.
The group also appear to be against the construction of Sizewell C.
I feel they have a point about too much development onshore, but I feel that if the UK is to thrive in the future we need an independent zero carbon energy source.
I also believe that thousands of wind farms in the seas around the UK and Ireland are the best way to obtain that energy.
Blending Hydrogen With Natural Gas
Blending green hydrogen produced in an electrolyser with natural gas is an interesting possibility.
- HyDeploy is a project to investigate blending up to 20 % of green hydrogen in the natural gas supply to industrial and domestic users.
- Partners include Cadent, ITM Power, Keele University and the Health and Safety Executive.
- Natural gas naturally contains a small amount of hydrogen anyway.
- The hydrogen gas would be distributed to users in the existing gas delivery network.
I wrote about HyDeploy in a post called HyDeploy.
Thje only loser, if hydrogen were to be blended with natural gas would be Vlad the Poisoner, as he’d sell less of his tainted gas.
An Interconnector Between Bicker Fen And Freeport East
I believe that an electricity interconnector between at least Bicker Fen and Freeport East could solve some of the problems.
My objectives would be.
- Avoid as much disruption on the land as possible.
- Create the capacity to deliver all the energy generated to customers, either as electricity or hydrogen.
- Create an expandable framework, that would support all the wind farms that could be built in the future.
The interconnector would be a few miles offshore and run along the sea-bed.
- This method of construction is well proven.
- It was used for the Western HVDC Link between Hunterston in Scotland and Connah’s Quay in Wales.
- Most wind farms seem to have existing substations and these would be upgraded to host the interconnector.
Connections en route would include.
Dudgeon Offshore Wind Farm
The interconnector would connect to the existing offshore substation.
Sheringham Shoal Wind Farm
The interconnector would connect to the existing offshore substation.
Dudgeon and Sheringham Shoal Extension Offshore Wind Farms
These two wind farms could be connected directly to the interconnector, if as planned, they shared an offshore substation in the Sheringham Shoal Extension offshore wind farm.
Bacton Gas Terminal
I would connect to the Bacton Gas Terminal, so that a large electrolyser could be installed at the terminal.
The hydrogen produced could be.
- Stored in depleted gas fields connected to the terminal.
- Blended with natural gas.
- Exported to Europe through an interconnector.
- Supplied to local users by truck or pipeline.
After all, the terminal has been handling gas for over fifty years, so they have a lot of experience of safe gas handling.
Norfolk Boreas And Norfolk Vanguard
These two wind farms could be connected directly to the interconnector, if they shared an offshore substation.
It would also help to appease and silence the objectors, if there was no need to dig up half of Norfolk.
Great Yarmouth And Lowestoft
It might be better, if these ports were supplied from the interconnector.
- Either port could have its own electrolyser to generate hydrogen, which could be.
- Used to power ships, trucks and port equipment.
- Liquefied and exported in tankers.
- Used to supply local gas users.
- Hydrogen could be supplied to a converted Great Yarmouth power station.
Both Great Yarmouth and Lowestoft could become hydrogen hub towns.
Sizewell
This site has a high-capacity connection to the National Grid. This connection is a big eyesore, but it needs to run at full capacity to take electricity from the Energy Coast to the interior of England.
That electricity can come from Sizewell B and/or Sizewell C nuclear power stations or the offshore wind farms.
East Anglia Array
There would probably need to be a joint offshore substation to control the massive amounts of electricity generated by the array.
Currently, the only wind farm in operation of this group is East Anglia One, which uses an underground cable connection to the Sizewell high-capacity connection to the Bullen Lane substation at Bramford.
Freeport East, Ipswich And Bullen Lane Substation
This Google Map shows the area between Ipswich and the coast.
Note.
- Sizewell is in the North-East corner of the map.
- Felixstowe, Harwich and Freeport East are at the mouth of the rivers Orwell and Stour.
- The Bullen Lane substation is to the West of Ipswich and shown by the red arrow.
I would certainly investigate the possibility of running an underwater cable up the River Orwell to connect the Southern end of the interconnector Between Bicker Fen And Freeport East.
This Google Map shows the Bullen Lane Substation.
It looks impressive, but is it big enough to handle all the electricity coming ashore from the offshore wind farms to the East of Suffolk and the electricity from the power stations at Sizewell?
Conclusion
I believe there are a lot of possibilities, that would meet my objectives.
In addition, simple mathematics says to me, that either there will need to be extra capacity at both Bicker Fen and Bullen Lane substations and onward to the rest of the country, or a large electrolyser to convert several gigawatts of electricity into hydrogen for distribution, through the gas network.
ITM Power’s 24MW Electrolyser Sale to Yara
The title of this post, is the similar to that of this press release from ITM Power. I just added a few words.
These are the first three paragraphs.
ITM Power (AIM: ITM), the energy storage and clean fuel company, is pleased to provide details of the sale of a 24MW electrolyser to Linde Engineering contained in the Company’s Half Year Report issued yesterday. The electrolyser is to be installed at a site operated by Yara Norge AS (“Yara”) located at Herøya outside Porsgrunn, about 140 km southwest of Oslo. The site covers an area of approximately 1.5 square kilometres and is the largest industrial site in Norway. The Porsgrunn site produces 3 million tons of fertiliser per year.
The hydrogen required for ammonia production is currently produced from SMR. Yara intends to start replacing this grey hydrogen with green hydrogen produced from renewable energy and electrolysis. The 24MW system supplying 10,368 kg/day of hydrogen will account for approximately 5% of the plant’s consumption and serve as a feasibility study for future upscaling. Yara has received a grant of up to NOK 283m (£23.6m,pending ESA approval) from Enova SF, a Government funding body, to invest in green solutions for hydrogen used for industrial purposes in Norway.
The electrolyser equipment is due to be ready for shipment from ITM Power in Q4 2022 with revenue realised in the Company’s 2022/2023 financial year.
These are my thoughts.
The Size Of The Electrolyser
A 24 MW electrolyser, that produces 10,368 Kg of hydrogen/day may sound a large device.
This is an extract from the press release.
In January 2021, the Company received an order for the world’s then largest PEM electrolyser of 24MW from Linde. In October 2021, the Company, with Linde, announced the deployment of a 100MW electrolyser at Shell’s Rhineland refinery, following the start-up of an initial 10MW facility at the site.
It appears that ITM Power have built one before and one four times the size has been ordered.
What Size Of Electrolyser Would Yara Need To Fully Decarbonise Ammonia Production?
According to the press release, a 24 MW electrolyser will produce five percent of the plant’s consumption, which means that a 480 MW electrolyser will be needed, if Yara use an ITM electrolyser to produce all their hydrogen.
Will manufacture of an electrolyser of this size be a problem for ITM Power?
The press release says this about electrolyser production.
ITM Power operates from the world’s largest electrolyser factory in Sheffield with a capacity of 1GW (1,000MW) per annum, with the announced intention to build a second UK Gigafactory in Sheffield with a capacity of 1.5GW expected to be fully operational by the end of 2023. The Group’s first international facility, expected to have a capacity of 2.5GW per annum, is intended to be operational by the end of 2024, bringing total Group capacity to 5GW per annum.
It also says that the company has raised £250m to accelerate expansion.
The Delivery Date
The delivery date of the electrolyser is stated as Q4 2022.
I find this rather quick, which makes me believe that one of the reasons for the success of ITM Power is their production process.
How Much Ammonia Is Produced Worldwide?
This is an extract from this publication from the Royal Society, which is entitled Ammonia: Zero-Carbon Fertiliser, Fuel And Energy Store.
Current global ammonia production is about 176 million tonnes per year and is predominantly achieved through the steam reforming of methane to produce hydrogen to feed into ammonia synthesis via the Haber Bosch process.
Ammonia production is a highly energy intensive process consuming around 1.8% of global energy output each year (steam methane reforming accounts for over 80% of the energy required) and producing as a result about 500 million tonnes of carbon dioxide (about 1.8% of global carbon dioxide emissions)2,3,4. Ammonia synthesis is significantly the largest carbon dioxide emitting chemical industry process. Along with cement, steel and ethylene production, it is one of the ‘big four’ industrial processes where a decarbonisation plan must be developed and implemented to meet the netzero carbon emissions target by 2050.
It looks like Linde and ITM Power have a fairly simple plan to decarbonise world ammonia production. And they have started with one of the easier targets; Yara in the very environmentally-correct Norway.
I estimate that to produce 176 million tonnes of green ammonia will need over 28 GW of electrolyser capacity.
Conclusion
If Linde and ITM Power can persuade the world, that their technology is the way to go, then they’ve got it made.
