How Will The UK Power All These Proposed Data Centres?
On Wednesday, a cardiologist friend asked me if we have enough power to do Trump’s UK AI, so I felt this post might be a good idea.
Artificial Intelligence Gave This Answer
I first asked Google AI, the title of this post and received this reply.
The UK will power proposed data centres using a mix of grid-supplied low-carbon electricity from sources like offshore wind and through on-site renewable generation, such as rooftop solar panels. Data centre operators are also exploring behind-the-meter options, including battery storage and potential future nuclear power, to meet their significant and growing energy demands. However, the UK’s grid infrastructure and high energy prices present challenges, with industry calls for grid reform and inclusion in energy-intensive industry support schemes to facilitate sustainable growth.
Google also pointed me at the article on the BBC, which is entitled Data Centres To Be Expanded Across UK As Concerns Mount.
This is the sub-heading.
The number of data centres in the UK is set to increase by almost a fifth, according to figures shared with BBC News.
These are the first three paragraphs.
Data centres are giant warehouses full of powerful computers used to run digital services from movie streaming to online banking – there are currently an estimated 477 of them in the UK.
Construction researchers Barbour ABI have analysed planning documents and say that number is set to jump by almost 100, as the growth in artificial intelligence (AI) increases the need for processing power.
The majority are due to be built in the next five years. However, there are concerns about the huge amount of energy and water the new data centres will consume.
Where Are The Data Centres To Be Built?
The BBC article gives this summary of the locations.
More than half of the new data centres would be in London and neighbouring counties.
Many are privately funded by US tech giants such as Google and Microsoft and major investment firms.
A further nine are planned in Wales, one in Scotland, five in Greater Manchester and a handful in other parts of the UK, the data shows.
While the new data centres are mostly due for completion by 2030, the biggest single one planned would come later – a £10bn AI data centre in Blyth, near Newcastle, for the American private investment and wealth management company Blackstone Group.
It would involve building 10 giant buildings covering 540,000 square metres – the size of several large shopping centres – on the site of the former Blyth Power Station.
Work is set to begin in 2031 and last for more than three years.
Microsoft is planning four new data centres in the UK at a total cost of £330m, with an estimated completion between 2027 and 2029 – two in the Leeds area, one near Newport in Wales, and a five-storey site in Acton, north-west London.
And Google is building a data centre in Hertfordshire, an investment worth £740m, which it says will use air to cool its servers rather than water.
There is a map of the UK, with dots showing data centres everywhere.
One will certainly be coming to a suitable space near you.
Concerns Over Energy Needs
These three paragraphs from the BBC article, talk about the concerns about energy needs.
According to the National Energy System Operator, NESO, the projected growth of data centres in Great Britain could “add up to 71 TWh of electricity demand” in the next 25 years, which it says redoubles the need for clean power – such as offshore wind.
Bruce Owen, regional president of data centre operator Equinix, said the UK’s high energy costs, as well as concerns around lengthy planning processes, were prompting some operators to consider building elsewhere.
“If I want to build a new data centre here within the UK, we’re talking five to seven years before I even have planning permission or access to power in order to do that,” he told BBC Radio 4’s Today programme.
But in Renewable Power By 2030 In The UK, I calculated that by 2030 we will add these yearly additions of offshore wind power.
- 2025 – 1,235 MW
- 2026 – 4,807 MW
- 2027 – 5,350 MW
- 2028 – 4,998 MW
- 2029 – 9,631 MW
- 2030 – 15,263 MW
Note.
- I have used pessimistic dates.
- There are likely to be more announcements of offshore wind power in the sea around the UK, in the coming months.
- As an example in Cerulean Winds Submits 1 GW Aspen Offshore Wind Project In Scotland (UK), I talk about 3 GW of offshore wind, that is not included in my yearly totals.
- The yearly totals add up to a total of 58,897 MW.
For solar power, I just asked Google AI and received this answer.
The UK government aims to have between 45 and 47 gigawatts (GW) of solar power capacity by 2030. This goal is set out in the Solar Roadmap and aims to reduce energy bills and support the UK’s clean power objectives. The roadmap includes measures like installing solar on new homes and buildings, exploring solar carports, and improving access to rooftop solar for renters.
Let’s assume that we only achieve the lowest value of 45 GW.
But that will still give us at least 100 GW of renewable zero-carbon power.
What will happen if the wind doesn’t blow and the sun doesn’t shine?
I have also written about nuclear developments, that were announced during Trump’s visit.
- Centrica And X-energy Agree To Deploy UK’s First Advanced Modular Reactors
- Is Last Energy The Artemis Of Energy?
- National Grid And Emerald AI Announce Strategic Partnership To Demonstrate AI Power Flexibility In The UK
- Nuclear Plan For Decommissioned Coal Power Station
- Raft Of US-UK Nuclear Deals Ahead Of Trump Visit
- Rolls-Royce Welcomes Action From UK And US Governments To Usher In New ‘Golden Age’ Of Nuclear Energy
This is an impressive array of nuclear power, that should be able to fill in most of the weather-induced gaps.
In Renewable Power By 2030 In The UK, I also summarise energy storage.
For pumped storage hydro, I asked Google AI and received this answer.
The UK’s pumped storage hydro (PSH) capacity is projected to more than double by 2030, with six projects in Scotland, including Coire Glas and Cruachan 2, potentially increasing capacity to around 7.7 GW from the current approximately 3 GW. This would be a significant step towards meeting the National Grid’s required 13 GW of new energy storage by 2030, though achieving this depends on policy support and investment.
There will also be smaller lithium-ion batteries and long duration energy storage from companies like Highview Power.
But I believe there will be another source of energy that will ensure that the UK achieves energy security.
SSE’s Next Generation Power Stations
So far two of these power stations have been proposed.
Note.
- Both power stations are being designed so they can run on natural gas, 100 % hydrogen or a blend of natural gas and hydrogen.
- Keadby will share a site with three natural gas-powered power stations and be connected to the hydrogen storage at Aldbrough, so both fuels will be available.
- Ferrybridge will be the first gas/hydrogen power station on the Ferrybridge site and will have its own natural gas connection.
- How Ferrybridge will receive hydrogen has still to be decided.
- In Hydrogen Milestone: UK’s First Hydrogen-to-Power Trial At Brigg Energy Park, I describe how Centrica tested Brigg gas-fired power station on a hydrogen blend.
- The power stations will initially run on natural gas and then gradually switch over to lower carbon fuels, once delivery of the hydrogen has been solved for each site.
On Thursday, I went to see SSE’s consultation at Knottingley for the Ferrybridge power station, which I wrote about in Visiting The Consultation For Ferrybridge Next Generation Power Station At Knottingley.
In the related post, I proposed using special trains to deliver the hydrogen from where it is produced to where it is needed.
Could HiiROC Be Used At Ferrybridge?
Consider.
- HiiROC use a process called thermal plasma electrolysis to split any hydrocarbon gas into hydrogen and carbon black.
- Typical input gases are chemical plant off gas, biomethane and natural gas.
- Carbon black has uses in manufacturing and agriculture.
- HiiROC uses less energy than traditional electrolysis.
- There is an independent power source at Ferrybridge from burning waste, which could be used to ower a HiiROC system to generate the hydrogen.
It might be possible to not have a separate hydrogen feed and still get worthwhile carbon emission savings.
Conclusion
I believe we will have enough electricity to power all the data centres, that will be built in the next few years in the UK.
Some of the new power stations, that are proposed to be built, like some of the SMRs and SSE’s Next Generation power stations could even be co-located with data centres or other high energy users.
In Nuclear Plan For Decommissioned Coal Power Station, I describe how at the former site of Cottam coal-fired power station, it is proposed that two Holtec SMR-300 SMRs will be installed to power advanced data centres. If the locals are objecting to nuclear stations, I’m sure that an SSE Next Generation power station, that was burning clean hydrogen, would be more acceptable.
Consultation Opens For Ferrybridge Next Generation Power Station
The title of this post, is the same as that of this press release from SSE.
These three bullet points act as sub-headings.
- Ferrybridge Next Generation sets out plans for continuing the legacy of power generation at the site, with the potential to bring significant investment to the region.
- Statutory consultation phase launched, inviting communities and stakeholders to have their say on project proposals.
- Hydrogen-enabled project could support the security of supply and offer a clear route to decarbonisation.
These three paragraphs add more detail.
Members of the public are being invited to have their say on plans for a proposed new power station in development, Ferrybridge Next Generation Power Station.
The station is being designed so that it can run on hydrogen, as a lower-carbon alternative to natural gas. It would also be able to operate using natural gas or a blend of hydrogen and natural gas until a technically and commercially viable hydrogen supply becomes available to the site.
With a proposed capacity of up to 1.2GW, Ferrybridge Next Generation Power Station could play an important role in supporting the UK’s energy system in the short term – providing reliable flexible back-up power during periods of peak demand and balancing the system when the wind doesn’t blow or the sun doesn’t shine, while delivering a route to decarbonised power generation in the longer term.
Note.
- A 150 MW/300 MWh Battery Electric Storage System is being developed on the site, which I wrote about in SSE Renewables Announces Construction Of Second Utility-Scale Battery Storage System.
- The last Ferrybridge power station; C had a capacity of just over 2 GW.
- This will be SSE Renewable’s second hydrogen-fired power station after Keadby, which I wrote about in Consultation On Plans For Keadby Hydrogen Power Station To Begin.
- As the press releases says, Ferrybridge Hydrogen-Fired Power Station will be West Yorkshire’s backup for when the wind doesn’t blow and the sun doesn’t shine.
How similar will the two hydrogen-fired power stations be?
Will SSE Be Building Any More In The First Wave Of Hydrogen-Fired Power Station?
This is a paragraph from SSE’s press release.
The station is being designed so that it can run on hydrogen, as a lower-carbon alternative to natural gas. It would also be able to operate using natural gas or a blend of hydrogen and natural gas until a technically and commercially viable hydrogen supply becomes available to the site.
It would appear that the availability of the hydrogen fuel may be a problem.
But places like Aberdeen, Bradford, Brighton, Humberside and Merseyside, do seem to be planning for hydrogen, so all is not lost.
Reform Declares War On County’s Net-Zero Projects
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
Reform UK leaders in Lincolnshire say they have “declared war” on green energy projects.
These three paragraphs outline their policies.
Boston and Skegness MP Richard Tice, Greater Lincolnshire’s mayor Dame Andrea Jenkyns and Councillor Sean Matthews, who leads the county council, launched a campaign at a press conference held in Boston earlier.
They said they opposed wind and solar farms and battery storage facilities, with Tice adding: “It is an absolute outrage what the madness of net stupid zero is doing to our county, as well as to our country.”
The government said green energy was vital in delivering energy security, while Labour MP Melanie Onn argued Reform’s stance posed a risk to thousands of jobs.
It should be noted that Lincolnshire has a lot of projects, that will be concerned with renewable energy.
Lincolnshire is one of the UK counties, with the highest level of wind power.
- There are over 7 GW of wind farms, that already do or will land their electricity in the county including 5.5 GW from the world’s largest offshore wind farm; Hornsea.
- There is approaching 300 MW of onshore wind in the county, which includes England’s largest onshore wind farm at Keadby, which is 68 MW.
I asked Google how much solar there was in the county and I got this AI Overview.
Lincolnshire has a significant amount of solar power capacity, with several large solar farms and numerous smaller installations. The county is a major location for solar energy development, with some projects aiming to power tens or even hundreds of thousands of homes.
In the real world of wind and solar energy, all of this renewable energy will need backup and the county has it in hundreds of megawatts.
- Keadby One is a 732 MW gas-fired power station owned by SSE Thermal.
- Keadby Two is a 849 MW gas-fired power station owned by SSE Thermal.
- Keadby Three will be a 910 gas-fired power station, fitted with carbon capture, that is being developed by SSE Thermal.
- Keadby Next Generation Power Station is a 1800 MW hydrogen-powered power station, that is being developed by Equinor and SSE Thermal. I wrote about it in Consultation On Plans For Keadby Hydrogen Power Station To Begin and it will generate 900 MW of zero-carbon electricity.
Now that it what I call backup.
Conclusion
Lincolnshire generates a lot of renewable energy and Reform UK want to throw it all away.
As I showed in US Gov’t Withdraws All Offshore Wind Energy Areas, Trump’s policies against renewable energy and wind in particular are not good for investment and employment.
We don’t want Trump’s policies in the UK.
And especially in Lincolnshire, where all this energy can attract jobs.
Slough Multifuel Energy-From-Waste Facility Begins Operations
The title of this post, is the same as that of this news item from SSE Thermal.
This is the sub-heading.
SSE Thermal and Copenhagen Infrastructure Partners (CIP), partners of a new energy-from-waste facility in Slough, have entered commercial operations ahead of schedule.
This section from the news item describes the operation of the plant.
Slough Multifuel will produce electricity and heat through burning waste-derived fuels made from various sources of:
- municipal solid waste
- commercial and industrial waste
- waste wood
The 55 MW facility will divert thousands of tonnes of waste away from landfill. It will convert it into a valuable source of energy. The facility is expected to process around 480,000 tonnes of residual waste each year. The station will support the UK Government’s strategy to reduce landfill waste and the export of waste.
Effectively, it is a sophisticated state-of-the-art incinerator, that has been built by Hitachi Zosen Inova.
In an ideal world, everything would be recycled and there would be no landfill or incineration.
But that would only be possible in a green fascist state.
SSE Thermal Acquires 50% Stake In H2NorthEast Hydrogen Project
The title of this post is the same as that of this press release from SSE Thermal.
These are the first three introductory paragraphs.
SSE Thermal has become joint owner of a blue hydrogen project in Teesside which is set to play a major role in supporting a reliable decarbonised power system by 2035 and accelerating industrial decarbonisation.
The partnership with Kellas Midstream will see the companies jointly develop H2NorthEast, a hydrogen production facility with carbon capture and storage that could help to kickstart a hydrogen economy in the Tees Valley. The agreement is for an initial consideration of <£10m to Kellas Midstream with further contingent consideration due should the project reach a financial investment decision.
In its first phase, H2NorthEast could deliver up to 355MW of blue hydrogen production capacity from 2028 with plans to scale up to more than 1GW. Offtakers would include heavy industry and power generation, either through blending into existing assets or in new hydrogen-fired plants.
Note.
- Production of 355 MW of hydrogen could start in 2028.
- Several existing processes have been converted from gas-firing to hydrogen-firing or a blend of natural gas and hydrogen firing. See Lime Kiln Fuelled By Hydrogen Shown To Be Viable.
- Teesside has quite a few industries, like steel and chemicals that theoretically could be converted to hydrogen or a hydrogen blend.
I have some thoughts.
Carbon Capture And Storage
This paragraph in the press release talks about the carbon capture and storage.
With an anticipated minimum carbon capture rate of 97%, H2NorthEast meets both UK and EU low-carbon standards. Specifically, the hydrogen produced via H2NorthEast would be fully compliant with both the UK’s Low Carbon Hydrogen Standard and is expected to be aligned with the EU Taxonomy for sustainable activities.
If the plant can achieve a carbon capture rate of 97 %, that is very good and it appears to meet the required standards.
- I also feel, that if it is of a high purity, then that could be a bonus, as it could be used in food manufacturing and other processes, where high purity is needed.
- I feel SSE should endeavour to use as much of the carbon dioxide, as it can to produce valuable by-products, which could include cement substitutes, building blocks, plasterboard and animal feed.
- Carbon dioxide can also be fed to soft fruit, salad vegetables, tomatoes, flowers and other plants in giant greenhouses or vertical farms.
- Polyester yarn can also be made from carbon dioxide.
It is my belief that this list of products will grow in the next ten years and carbon dioxide of a high purity will become an important chemical feedstock.
Replacement of Blue Hydrogen With Green
If SSE Renewables were to build an electrolyser near to H2NorthEast, they could use that to replace the blue hydrogen.
- From an offtaker’s point of view green and blue hydrogen would be identical.
- It’s just that the green hydrogen doesn’t produce any carbon dioxide.
- I can see the complex being run to produce enough carbon dioxide to supply the users that need it and producing blue and/or green hydrogen accordingly.
Hopefully, the more uses that can be found for the carbon dioxide, the less of it will need to use long-term storage.
Expanding The Plant
As blue and green hydrogen plants create an identical product, the decision of whether to add an extra blue hydrogen or green hydrogen plant can be taken solely on financial grounds.
Conclusion
This looks like it could be a very sensible decision by SSE.
Did I See The UK’s Hydrogen-Powered Future In Hull Today?
I went from London to Hull today on Hull Trains for £50.80 return (with my Senior Railcard) to see SSE’s presentation for their Aldbrough Pathfinder Hydrogen project, which will feature a 35 MW green hydrogen electrolyser and 320 GWh of hydrogen storage in the thick layers of salt under East Yorkshire.
- Green electricity would come mainly from the part-SSE owned 8 GW Dogger Bank wind farm complex.
- According to their web site, Meld Energy are planning a 100 MW electrolyser, which would produce 13,400 tonnes of hydrogen per year.
Every large helps!
- It should be noted that the thick layers of salt stretch all the way to Germany, and as drilling and storage technology improves, the amount of hydrogen storage available will increase.
- I was also impressed by the ambition, competence and enthusiasm, of the SSE engineers that I met.
- As has been pointed out, HiiROC, who have backing from Centrica, Hyundai, Kia and others, are also in Hull!
I believe, that I saw our hydrogen-powered future in Hull today!
We need more hydrogen mega-projects like these! Perhaps in Aberdeen, Clydeside, Freeport East, Isle of Grain, Merseyside, Milford Haven and Teesside?
Have Your Say About Potential New Hydrogen Facility In Aldbrough
The title of this post, is the same as that of this article on HullLive.
This is the first paragraph.
SSE Thermal is looking for input from the local community regarding its first-of-a-kind low-carbon hydrogen facility.
They are holding meetings in the Hull area as follows to discuss the project with anybody who is interested.
- Tuesday, June 6, 2:30pm – 7pm: Hedon Town Hall, 36 St Augustine’s Gate, Hedon, HU12 8EX
- Wednesday, June 7, 2:30pm – 7pm: East Village Meadows, Northfield Farm, Garton, HU11 4QB
- Thursday, June 8, 2:30pm – 7pm: Aldbrough Village Hall, Garton Rd, Aldbrough, HU11 4QA
I shall be going on the Tuesday. There are buses from Hull station, which take about 35 minutes.
This section is copied from the HullLive article.
What is the Pathfinder Project?
The Aldbrough Hydrogen Pathfinder project is an important building block in the development of a thriving Humber hydrogen economy, underpinning the region’s decarbonisation and supporting economic growth locally and nationally.
The project is proposed to be developed within its existing site at Aldbrough Gas Storage, and all visible infrastructure will be within the site boundary.
The project intends to use one of the current storage caverns and repurpose it to develop a project in the Humber that would unite hydrogen production, storage and power generation in one.
As someone, who feels strongly about the benefits of hydrogen, I feel this is a very worthwhile project.
SSE Thermal Secures 10-year Contracts For Two New Low-Carbon Power Stations In Ireland
The title of this post, is the same as that of this press release from SSE.
These first two paragraphs outline the two projects.
SSE Thermal, as part of SSE plc, has provisionally secured 10-year capacity agreements for its two proposed new-build power stations in Ireland which would run on sustainable biofuel.
The proposed low-carbon units at Tarbert in Co. Kerry and Platin in Co. Meath received the contracts in the T-4 Capacity Auction to commence in the 2026/27 delivery year.
Note.
- Both plants would help to protect security of supply and provide flexible backup to Ireland’s growing renewables sector.
- This Wikipedia entry is entitled Renewable Entry In Ireland and states that by the end of 2021, Ireland had 4.4 GW of onshore wind, with the intention of adding 5 GW of offshore wind, by 2030.
- The proposed units will initially run on Hydrotreated Vegetable Oil (or HVO), which is produced by processing waste oils to create a fossil-free alternative to diesel in accordance with EU sustainability standards.
- It looks like the two new-build HVO-powered station will back up the renewables.
- It is intended that the two new power stations will be in operation in 2026.
The two new power stations will be convertible to hydrogen in the future.
As at Keadby in Lincolnshire, which I wrote about in SSE Thermal Charts Path To Green Hydrogen Future With First-Of-A-Kind Project. it looks like SSE have developed a comprehensive plan to keep the electricity at full power, even when the wind isn’t blowing.
Conclusion
SSE Thermal are showing that in addition to gas, nuclear and pumped storage hydroelectric, renewables can also be backed up by biomass.
SSE Thermal Is Charting A Path For Low-Carbon Flexible Generation In Ireland
The title of this post, is the same as that of this news item from SSE.
This is the sub-heading.
SSE Thermal, as part of SSE plc, is exploring options to develop two new low-carbon power stations in Ireland which would help to protect security of supply and provide flexible backup to renewable generation.
This three paragraphs outline the project.
Sites in Tarbert in County Kerry and at Platin in County Meath, could provide the location for these new power stations, which would initially run on sustainable biofuel with the potential to convert to hydrogen in the future.
Biofuel provides a lower carbon option for use in power stations, using waste feedstocks to produce valuable flexible electricity making it an important transitionary solution as plans for a greater use of hydrogen and carbon capture are developed. The proposed units will run on Hydrotreated Vegetable Oil (or HVO), which is produced by processing waste oils to create a fossil-free alternative to diesel in accordance with EU sustainability standards.
Development at the two sites could provide up to 450MW of new generation capacity to the grid, with up to 300MW at Tarbert and 150MW at Platin. While in early development and still subject to a final investment decision, these new power stations could be operational as early as 2027, bringing with them the potential to underpin demand for low-carbon hydrogen in Ireland.
One problem is that SSE’s existing Tarbert Power Station is required to close by the end of 2023 in line with its environmental licence. So it looks like they’ll have to get going quickly.
Lessons From Keadby 2
Keadby 2 is one of SSE Thermal’s newest power stations and it is described in this page on the SSE Thermal web site, which is entitled Keadby 2 Power Station.
These are first three paragraphs from the page.
Keadby 2 is a new 893MW gas-fired power station in North Lincolnshire currently being constructed by our EPC contractor Siemens Energy. The project is adjacent to our operational Keadby 1 Power Station.
SSE Thermal has partnered with Siemens Energy to introduce first-of-a-kind, high-efficiency gas-fired generation technology to the UK. When completed, Keadby 2 is expected to become the cleanest and most-efficient gas-fired power station in Europe.
The station will also be capable of being upgraded to further decarbonise its generation through carbon capture or hydrogen technology, as routes to market develop.
Note.
- Siemens Energy seem to be able to deliver large gas-fired power stations to satisfy SSE Thermal.
- Looking at the data sheets for Siemens Energy’s heavy-duty gas-turbines, they can run on a wide range of fuel including biodiesel.
- This document from Siemens Energy describes work to run their gas-turbines on HVO.
- If Keadby 2 can be upgraded to run on hydrogen, I can see no reason why Tarbert and Platin won’t be able to be similarly upgraded in the future.
SSE Thermal seem to be following a similar philosophy to generate lower-carbon electricity at Keadby and in Ireland.
Could We See A Large HVO-Fuelled Power Station In The UK?
I wonder, if we’ll see a large HVO-fuelled power station in the UK?
It appears SSE and Siemens will have the technology and expertise.
I suspect it depends on there being large amounts of HVO available.
The Anonymous Widower
