Backing Up The Wind With The Keadby Power Stations
I went to Cleethorpes from Doncaster by train yesterday. You pass the Keadby site, where there are two large gas–fired power stations of 734 MW and 710 MW. A third one ; Keadby 3 of 910 MW complete with carbon capture and storage should join them by 2027.
So that will be nearly 2.5 GW of reliable electricity.
I find it interesting that one of our first gas-fired power stations with carbon capture will be in Lincolnshire, which is famous for growing plants of all shapes, types and sizes. So will we be seeing lots of greenhouses on the flat lands I saw yesterday, growing plants in an atmosphere they like, so that we can generate our carbon dioxide and eat it.
The next power station at Keadby is called the Keadby Next Generation power station, which is intended to be complete by 2030. It is a bit of a puzzle in that it will run on up to 1800 MW of hydrogen and only produce up to 910 MW of electricity.
Note.
- The hydrogen will come from SSE’s hydrogen store at Aldbrough and Centrica’s store at Rough.
- Surely, the amount of hydrogen and electricity should balance.
When I worked in ICI’s hydrogen plant in the 1960s, ICI had no use for the hydrogen, so they sent it to their power station, blended it with coal gas and used it to make steam for other processes.
Could Keadby Next Generation power station be providing zero-carbon steam for the chemical and other processes on Humberside?
Adding the 910 MW of electricity to Keadby’s gas-fired total of 2.5 GW gives 3.4 GW of electricity from Keadby to back up the wind farms.
3.4 GW at Keadby is what I call backup!
It also should be noted, that one of the reasons for building the Mersey Tidal Barrage is to provide backup for all the wind farms in Liverpool Bay.
Conclusion
I believe that SSE could be supplying zero-carbon steam in addition to electricity from the Keadby Hydrogen power station.
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.
Grain LNG Launches Market Consultation For Existing Capacity
The title of this post is the same as that of this press release from National Grid.
This is the sub-heading.
Grain LNG, the largest liquefied natural gas (LNG) terminal in Europe, is pleased to announce the launch of a market consultation for the auction of 375 Gwh/d (approx. 9 mtpa) of existing capacity. The initial consultation phase for the Auction of Existing Capacity will commence on 14 June and run until 26 July.
These paragraphs detail what Grain LNG, which is a subsidiary of National Grid are offering.
GLNG has used the positive feedback received from the recent ‘Expression of Interest’ exercise and subsequent market engagement to offer three lots of capacity:
- Each lot will be entitled to 42 berthing slots, 200,000 m3 of storage and 125GWh/d (approx. 3 mtpa) of regasification capacity from as early as January 2029.
- This product is specifically designed for parties who wish to acquire a substantial stake in a major terminal in Northwest Europe, at a reduced cost and with shorter contract lengths when compared to new-build projects.
- As the terminal’s capacity already exists, parties involved will not be subjected to the FID approvals or potential delays that can arise from construction issues commonly associated with new build terminals.
Simon Culkin, Importation Terminal Manager at Grain LNG, said: “We are really pleased with the high level of interest shown by the market at a time of significant geo-political influence on our energy markets. It has allowed us to engage with potential customers and shape our offering to best meet their needs, whilst optimising access to this strategic asset. “
Reading the Wikipedia entry for the Grain LNG Terminal, it looks like it gets used as a handy store for natural gas.
About Phase 1 (2002–05), Wikipedia says this.
The new facilities enabled the Grain terminal to become a base supply to the NTS, with the ability to deliver gas continuously when required. The cost of the Phase 1 project was £130m. A 20-year contract with BP / Sonatrach enabled Grain LNG to import LNG on a long-term basis from July 2005.
About Phase 2 (2005–08), Wikipedia says this.
The development provided an additional five million tonnes of capacity per annum. All this capacity was contracted out from December 2010. Customers included BP, Iberdrola, Sonatrach, Centrica, E.ON and GDF Suez.
Under Current Facilities, Wikipedia says this.
Grain LNG Ltd does not own the LNG or the gas that it handles but charges for gasifying it. Current (2016) users include BP, Centrica (British Gas Trading), Iberdrola (Spain), Sonatrach (Algeria), Engie (France), and Uniper (Germany).
National Grid must be pleased that some customers seem loyal.
I feel that National Grid’s basic plan is to carry on with more of the same.
But will they develop more storage and other facilities on the site.
There are certainly other projects and interconnectors, that make the Isle of Grain and energy hub connecting the UK, Netherlands and Germany.
- In Did I See The UK’s Hydrogen-Powered Future In Hull Today?, I mentioned, that I thought that the Isle of Grain could be a location for an electrolyser and a hydrogen store.
- In EuroLink, Nautilus And Sea Link, I talk about new interconnectors, if which Nautilus might come to the Isle of Grain.
- In UK-German Energy Link Reaches Financial Close, I talk about NeuConnect, which will be an interconnector between the Isle of Grain ans Wilhelmshaven in Germany.
- The Isle of Grain is the landing point for the BritNed undersea power cable between The Netherlands and the UK.
I could also see National Grid building an East Coast interconnector to bring power from the wind farms off the East Coast of England to the Isle of Grain for distribution.
These are major wind farms South of the Humber.
- Dudgeon – 402 MW
- East Anglia 1 – 714 MW
- East Anglia 1 North – 800 MW
- East Anglia 2 – 900 MW
- Galloper – 504 MW – RWE
- Greater Gabbard – 504 MW
- Gunfleet Sands – 174 MW
- Hornsea 1 – 1218 MW
- Hornsea 2 – 1386 MW
- Hornsea 3 – 2852 MW
- Humber Gateway – 219 MW
- Lincs – 270 MW
- London Array – 630 MW
- Lynn and Inner Dowsing – 194 MW
- Race Bank – 580 MW
- Scroby Sands – 60 MW
- Sheringham Shoal – 317 MW
- Triton Knoll – 857 MW – RWE
- Dogger Bank A – 1235 MW
- Dogger Bank B – 1235 MW
- Dogger Bank C – 1218 MW
- Dogger Bank D – 1320 MW
- Dogger Bank South – 3000 MW RWE
- East Anglia 3 – 1372 MW
- Norfolk Boreas – 1396 MW
- Norfolk Vanguard – 1800 MW
- Outer Dowsing – 1500 MW
- North Falls – 504 MW – RWE
- Sheringham Shoal and Dudgeon Extensions – 719 MW
- Five Estuaries – 353 MW – RWE
Note.
- These figures give a total capacity of 28,333 MW.
- Five wind farms marked RWE are owned by that company.
- These five wind farms have a total capacity of 5618 MW.
- Will RWE export, their electricity to Germany through NeuConnect?
I can certainly see National Grid building one of the world’s largest electrolysers and some energy storage on the Isle of Grain, if an East Coast Interconnector is built.
SSE Thermal Outlines Its Vision For The UK’s Net Zero Transition
The title of this post is the same as that of this news item from SSE Thermal.
This is the opening statement.
SSE Thermal, part of SSE plc, is calling on government to turbocharge the delivery of low-carbon technologies to help deliver a net zero power system by 2035.
Two paragraphs then outline what the company is doing.
The low-carbon developer is bringing forward multiple low-carbon projects across the UK. This includes Keadby 3 Carbon Capture Power Station in the Humber – which is being developed in collaboration with Equinor and recently became the first power CCS project in the country to receive planning permission – and Aldbrough Hydrogen Pathfinder, which would unite hydrogen production, storage and power generation in one location by the middle of this decade.
These projects would form part of SSE’s £24bn investment programme in the UK, and in addition to supporting the decarbonisation of industrial heartlands and powering a low-carbon future, they would also help to secure a just transition for workers and communities.
The news item then talks about the future.
Now, SSE Thermal has published ‘A vision for the UK’s net zero transition’ which outlines the need for these low-carbon technologies and the potential of carbon capture and hydrogen in providing flexible back-up to renewables.
It also outlines the steps Government should take to facilitate this:
- Progress the deployment of carbon capture and storage (CCS) and hydrogen infrastructure in a minimum of four industrial areas by 2030.
- Support first-of-a-kind carbon capture and storage and hydrogen projects to investment decisions before the end of next year.
- Increase its ambition for power CCS to 7-9GW by 2030, with regular auctions for Dispatchable Power Agreements.
- Set out a policy ambition for hydrogen in the power sector and a strategy for delivering at least 8GW of hydrogen-capable power stations by 2030.
- Accelerate the delivery of business models for hydrogen transport and storage infrastructure, to kickstart the hydrogen economy.
These are my thoughts.
Carbon Capture And Use
There is no mention of Carbon Capture And Use, which in my view, should go hand in hand with Carbon Capture And Storage.
- Sensible uses for carbon dioxide include.
- Feeding it to plants like tomatoes, flowers, salad vegetables, soft fruit and herbs in greenhouses.
- Mineral Carbonation International can convert a dirty carbon dioxide stream into building products like blocks and plasterboard.
- Deep Branch, which is a spin-out from Nottingham University, can use the carbon dioxide to make animal feed.
- Companies like CarbonCure add controlled amounts of carbon dioxide to ready-mixed concrete to make better concrete and bury carbon dioxide for ever.
Surely, the more carbon dioxide that can be used, the less that needs to be moved to expensive storage.
Note.
- There is a lot of carbon dioxide produced in Lincolnshire, where there are a lot of greenhouses.
- At least three of these ideas have been developed by quality research in Universities, in the UK, Australia and Canada.
- I believe that in the future more uses for carbon dioxide will be developed.
The Government should do the following.
- Support research on carbon capture.
- Support Research on finding more uses for carbon dioxide.
Should there be a disposal premium or tax credit paid to companies, for every tonne of carbon dioxide used in their processes? It might accelerate some innovative ideas!
Can We Increase Power CCS to 7-9GW by 2030?
That figure of 7-9 GW, means that around a GW of CCS must be added to power stations every year.
Consider.
- It is probably easier to add CCS to a new-build power station, than one that is a couple of decades old.
- Better and more affordable methods of CCS would probably help.
- In Drax To Pilot More Pioneering New Carbon Capture Technology, I wrote about a promising spin-out from Nottingham University
- In Drax Secures £500,000 For Innovative Fuel Cell Carbon Capture Study, I wrote about another system at Drax, that captures carbon dioxide from the flue gases at Drax.
If we develop more ways of using the carbon dioxide, this will at least cut the cost of storage.
Can We Deliver At Least 8GW Of Hydrogen-Capable Power Stations By 2030?
Do SSE Thermal mean that these power stations will always run on hydrogen, or that they are gas-fired power stations, that can run on either natural gas of hydrogen?
In ‘A vision for the UK’s net zero transition’, this is said about the hydrogen power stations.
Using low-carbon hydrogen with zero carbon emissions at point of combustion, or blending hydrogen into existing stations.
So if these power stations were fitted with carbon capture and could run on any blend of fuel composed of hydrogen and/or natural gas, they would satisfy our needs for baseload gas-fired power generation.
Hydrogen Production And Storage
SSE’s vision document says this about Hydrogen Production.
Using excess renewables to create carbon-free hydrogen, alongside other forms of low-carbon hydrogen, which can then be stored and used to provide energy when needed.
SSE’s vision document also says this about Hydrogen Storage.
Converting existing underground salt caverns or creating new purpose-built caverns to store hydrogen and underpin the hydrogen economy.
This page on the SSE Thermal web site is entitled Aldbrough Has Storage, where this is said about storing hydrogen at Aldbrough.
In July 2021, SSE Thermal and Equinor announced plans to develop one of the world’s largest hydrogen storage facilities at the Aldbrough site. The facility could be storing low-carbon hydrogen as early as 2028.
With an initial expected capacity of at least 320GWh, Aldbrough Hydrogen Storage would be significantly larger than any hydrogen storage facility in operation in the world today. The Aldbrough site is ideally located to store the low-carbon hydrogen set to be produced and used in the Humber region.
From my own experience, I know there is a similar salt structure in Cheshire, which has also been used to store gas.
Earlier, I said, that one of the things, that SSE would like the Government to do is.
Progress the deployment of carbon capture and storage (CCS) and hydrogen infrastructure in a minimum of four industrial areas by 2030.
If Cheshire and Humberside are two sites, where are the other two?
Deciding What Fuel To Use
If you take the Humberside site, it can provide electricity to the grid in three ways.
- Direct from the offshore and onshore wind farms.
- Using natural gas in the gas-fired power stations.
- Using hydrogen in the gas-fired power stations.
SSE might even add a battery to give them a fourth source of power.
In the 1970s, I used dynamic programming with Allied Mills to get the flour mix right in their bread, with respect to quality, cost and what flour was available.
Finance For SSE Thermal Plans
The news item says this.
These projects would form part of SSE’s £24bn investment programme in the UK.
£24bn is not the sort of money you can realise solely from profits or in sock drawers or down sofas, but provided the numbers add up, these sorts of sums can be raised from City institutions.
Conclusion
I like SSE Thermal’s plans.
Cadent Launches Report Mapping Out Routes To Hydrogen Fuelled Vehicles On UK Roads
The title of this post is the same as that of this article on Gasworld.
This is the first paragraph.
A roadmap using hydrogen to decarbonise transport, particularly commercial transport, in the North West of the UK, has been unveiled by the country’s leading gas distribution network Cadent.
The article makes some points about hydrogen-powered transport.
- Using Cadent’s network to deliver hydrogen, rather than tube trailers, massively reduces the cost and makes fuel cell electric cars (FCEVs) available to the general public for around the same price as a battery electric vehicle or a conventional diesel car.
- FCEVs can travel further than battery electric vehicles and take the same time to refuel as a conventional petrol car.
- Grid-supplied hydrogen is the most cost-effective way of supplying hydrogen transport fuel at the required volume – up to six times cheaper than if delivered by trailer and 70 per cent cheaper than electrolysis.
Cadent‘s interest in all this, is not about selling gas, as their interest and income is totalling in transporting gas from producers to end users. So they don’t care whether they transport natural gas or hydrogen.
Hydrogen Storage
The article also discloses plans of INOVYN, a wholly owned subsidiary of INEOS, to develop a grid-scale hydrogen storage facility.
It will be in salt caverns in mid-Cheshire.
It will be able to hold 2,000 tonnes of hydrogen.
It is cheaper to store hydrogen in salt caverns, than on the surface.
The salt caverns have been used to store gas for decades.
This is a quote from the INOYN spokesman.
Storage is a vital component of delivering a viable hydrogen energy system in the UK.
I only had an indirect quick glimpse underground, when I worked at ICI in the area around 1970, but ICI’s salt expert, said they had enough salt in Cheshire to last 9,000 years at the current rate of extraction.
Salt in Cheshire, is a unique geological formation, that is very valuable to the UK and it looks like in the future, thar could enable hydrogen power.
Hydrogen Generation
The hydrogen will still need to be produced. Wikipedia has an entry caslled Hydrogran Production, which is fairly dismissive of electrolysis.
But in my view, hydrogen could be produced by electrolysis using wind power, as other methods like steam reforming of methane produce carbon-dioxide.
I particularly like the idea of building wind farms in clusters around offshore gas platforms, that have extracted all the gas from the fields, they were built to serve.
- Instead of running electricity cables to the wind farms, hydrogen is produced by electrolysis on the platform and this is transported to the shore using the same gas infrastructure, that brought the natural gas onshore.
- This could enable wind-farms to be developed much further offshore.
- If carbon capture is ever successfully made to work, the existing gas pipe could also be used to transfer the carbon dioxide offshore for storage in worked-out gas fields.
- The pipe between platform and shore could easily be made reversible, carrying hydrogen one way and carbon dioxide the other.
All of the technology required would also appear to be fully developed.
Conclusion
I am convinced that in the next few years, a hydrogen gas network can be created in parts of the UK.
The North West has advantages in becoming one of the first parts of the UK to have an extensive hydrogen network.
- It has the means to produce hydrogen gas.
- It has large wind farms in Liverpool Bay.
- There are worked-out gas fields, that might in the future be used for carbon storage.
- If INOVYN can store large quantities of hydrogen, this is a big advantage.
The biggest problem would be converting large numbers of houses and commercial premises from natural gas to hydrogen.
But, we’ve been through that process before, when we changed from town gas to natural gas in the 1960s and 1970s.
Should We Remove Gas From Our Houses?
I only use gas for heating.
- I feel that naked flames are not a good idea to have anywhere near people, as they can produce oxides of nitrgen, that causes health problems.
- Gas cookers are also a major cause of household fires.
- Technology is moving against cooking with gas, as more more to electric induction hobs.
- If you are fitting a new gas boiler, make sure it can be connected to hydrogen.
When I buy my next property, it will be all electric.
