Could Liverpool Develop A Massive Zero-Carbon Data Centre?
There is an article in The Sunday Times today, which is entitled Google Signs Nuclear Deal To Power AI Data Centres.
These are the first three paragraphs of the article.
Google has struck a deal with a nuclear power start-up to provide low-carbon energy for its data centres and AI operations, marking a world-first in the tech industry.
The California-based company said the agreement to buy energy from multiple small modular reactors developed by Kairos Power could help spur a nuclear revival in America.
The first reactor is scheduled to come online in America by 2030, followed by additional deployments through 2035.
I am not against nuclear-powered data centres, but could Liverpool build a massive zero-carbon data centre?
This Google Map shows Liverpool Bay, which is a vast expanse of water that stretches along the North Wales coast to Anglesey and all the way to the Isle of Man.
Note.
- The Isle of Man in the North-West corner.
- Liverpool, Birkenhead and the River Mersey in the South-East corner.
- Anglesey in the South-West corner.
- Blackpool with Morecambe Bay to its North in the North-East corner.
Liverpool Bay could be one of Europe’s zero-carbon energy powerhouses.
Wind Farms In Liverpool Bay
At the present time, these wind farms are producing electricity or planned in Liverpool Bay.
- Barrow – 90 MW – Commissioned in 2006
- Burbo Bank – 90 MW – Commissioned in 2007
- Burbo Bank Extension – 258 MW – Commissioned in 2017
- Gwynt y Môr – 576 MW – Commissioned in 2015
- North Hoyle – 60 MW – Commissioned in 2003
- Ormonde – 150 MW – Commissioned in 2012
- Rhyl Flats – 90 MW – Commissioned in 2009
- Walney – 367 MW – Commissioned in 2010
- Walney Extension – 659 MW – Commissioned in 2018
- West if Duddon Sands – 389 MW – Commissioned in 2014
- Awel y Môr – 500 MW – Planned
- Morecambe – 480 MW – Planned
- Mona – 1500 MW – Planned
- Morgan – 1500 MW – Planned
Note.
- 2509 MW has been commissioned.
- 3980 MW is being planned.
- That is a total of 6489 MW
I suspect more space in Liverpool Bay could be developed with wind farms.
Mersey Tidal Power
The Mersey Tidal Power project has a web site.
If it is built, it will probably be built by the South Korean company; K-Water and use some of the design principles of the Sihwa Lake Tidal Power Station.
It will likely have an output of around 1 GW and take ten years to build.
In the 1970s, I did some project management consultancy for Frederick Snow and Partners, and they showed me their plans for a Severn Barrage.
Their futuristic vision for the Severn Estuary was never built, as the Prime Minister of the time; Harold Wilson, felt coal was the future. See Last Of The Many!
I suspect that the Mersey Tidal Power project will be another variation on a proven theme.
Morecambe Bay Bridge And Tidal Barrage Proposal
In the Wikipedia entry for Morecambe Bay, there is a proposal for a bridge and tidal barrage across the bay, where this is said.
In 2004, a proposal was made to build a bridge across the bay flanked by wind turbines and using tidal power. Proposals from Northern Tidal Power Gateways in 2019 outlined a tidal barrage with a road running along on top.
If the Mersey Tidal Power project is a success, then why wouldn’t one across Morecambe Bay, be one too?
500 MW of zero-carbon tidal power would do nicely!
Nuclear Sites At Calder Hall, Heysham And Wylfa
These three nuclear stations have supplied electricity to the North-West of England.
- Calder Hall was the original Magnox site, which the Wikipedia entry says had a nameplate capacity of 240 MW and was decommissioned in 2003, after running for 47 years.
- Heysham is a powerful site which the Wikipedia entry says has a nameplate capacity of 2452 MW and will be decommissioned in 2028.
- Wylfa is an older, smaller Magnox site which the Wikipedia entry says had a nameplate capacity of 1190MW and was decommissioned in 2015.
As the sites are cleared, I am sure that we’ll see more nuclear power stations built on the sites.
How Much Electricity Does A Data Centre Use?
I found this paragraph in an NESO document.
Regardless of this, if we were to use existing market data and modelling projections, this could point to annual data centre electricity consumptions of between 3.6 TWh in 2020 to as much as 35 TWh by 2050.
Dividing by the hours in a year, indicates that an individual data centre could use between 0.4 and 4 GW of electricity.
Using my rough figures here from wind, tidal and nuclear, I suspect that the power on the Mersey will generate enough power for at least one data centre.
Liverpool Is On The Right Side Of The Country For Cables To North America
Cables will go straight out of Liverpool Bay, pass to the North of Ireland and across the Atlantic to somewhere like Puget Sound.
Liverpool has a superb location for a Transatlantic data centre, that connects to networks on both sides of the pond.
Could Underwater Data Centres Be Developed In Liverpool Bay?
This page on the Microsoft web site is entitled Microsoft Finds Underwater Datacenters Are Reliable, Practical And Use Energy Sustainably
These three paragraphs detail the research.
Earlier this summer, marine specialists reeled up a shipping-container-size datacenter coated in algae, barnacles and sea anemones from the seafloor off Scotland’s Orkney Islands.
The retrieval launched the final phase of a years-long effort that proved the concept of underwater datacenters is feasible, as well as logistically, environmentally and economically practical.
Microsoft’s Project Natick team deployed the Northern Isles datacenter 117 feet deep to the seafloor in spring 2018. For the next two years, team members tested and monitored the performance and reliability of the datacenter’s servers.
I would assume that Microsoft have continued the research, as with something like this you can’t be too careful.
But it would appear, that data centres and their servers could be submerged under the waters of Liverpool Bay.
London And Liverpool Will Be Under Two Hours By Train Within A Year
New Class 807 trains, which will be delivered within a year, will improve the train service between the two cities.
- Train times will be brought to around or even below two hours.
- , The extra trains will allow a second hourly service to be added.
- The extra service will additionally stop at Liverpool South Parkway station, for the airport.
- High Speed Two is claiming one hour and fifty minutes, between London and Liverpool.
Liverpool already has one of the best rail terminals in the North of England, as these pictures show.
With these service improvements, it will have a service to London and the South, that will be second to no other Northern station.
Liverpool Has A Refurbished Partly-Underground Suburban Railway With New Trains
Liverpool’s Metro is one of the best in Europe for a medium-sized city.
The Metro is also expanding with new routes and stations.
These pictures show the new Headbolt Lane station, which is swerved by the UK’s first battery-electric trains.
Liverpool Has Easy Access To Two International Airports
There are two international airports close by; Liverpool John Lennon and Manchester International.
- For Liverpool Airport, it’s a bus from Liverpool South Parkway station or an express bus from Liverpool city centre.
- For Manchester Airport, it’s a train from Lime Street station.
I am fairly sure, that a hydrofoil could connect Liverpool’s Waterfront and the Tidal Barrier to the airport.
North-West England Has A Rich University Tradition
Liverpool, Manchester and the surrounding area has several world-class universities and research establishments.
Some like The Pandemic Institute would be able to find uses for all the computing power and artificial intelligence on offer at a powerful data centre.
Liverpool Is A World City
Liverpool is a World City, where there is plenty of sport, entertainment and things to do.
Conclusion
Liverpool is installing the power infrastructure for a very large data centre, that will be able to handle the world’s largest and most difficult problems.
Wylfa: UK Government In Talks To Buy Nuclear Site – Report
The title of this post, is the same as that as this article on the BBC.
This is the sub-heading.
The UK government is reportedly in talks to take control of a site in north Wales where a planned nuclear project was scrapped in 2019.
These paragraphs outline the story.
State-owned Great British Nuclear is “in early discussions” with Hitachi, which owns the land at Wylfa, on Anglesey, the Financial Times reported.
A government spokesman said Wylfa was one of many “potential sites” that could host nuclear projects.
Hitachi abandoned its plans there in January 2019.
An unnamed minister told the FT that “tentative negotiations” with Hitachi had already begun, but said a deal might not be reached until after a general election expected later this year.
Tom Greatrex, chief executive of the Nuclear Industry Association and Virginia Crosbie, MP for Ynys Môn both welcomed the talks.
These are my thoughts.
Where Is Wylfa?
This Google Map shows Anglesey.
Wylfa power station is near Wylfa Head at the top of the map, where they are indicated by the cluster of red arrows.
This Google Map shows the power station to a larger scale.
Note.
- The red arrow named Magnox marks the decommissioned Magnox power station.
- The topmost red arrow marks Wylfa Head.
- The rightmost red arrow marks Porth y Wylfa, which looks like a small harbour.
- On some maps the square building to the East of the power station is marked as Wylfa sub-station.
- There certainly appears to be an overhead transmission line leading South from the power station complex.
Virginia Crosbie, MP for Ynys Môn, also said this according to the BBC article.
The nuclear industry is unanimous that Wylfa is the best site in Europe for large-scale nuclear,” she said, adding that it would be “the largest inward investment” in Welsh history and “transformational” for the people of north-west Wales.
But I do wonder, if when you have cleared the Wylfa site leaving the sub-station, that it could be a site where renewables could come ashore and be fed into the grid.
Why Is Wylfa The Best Site In Europe For Large-Scale Nuclear?
Given the protests about putting new power transmission lines across Norfolk and Suffolk, I feel that Wylfa’s largest asset could be its high capacity connection to the UK’s grid.
According to the Wikipedia entry for Wylfa power station, this is said about Wylfa B.
Horizon Nuclear Power, originally an E.ON and RWE joint venture, bought by Hitachi in 2012, announced in 2009 intentions to install about 3,000 MWe of new nuclear plant at Wylfa. Horizon planned to build two advanced boiling water reactors (ABWRs) at a site to the south of the existing Wylfa station.
It would seem that the high capacity connection to the UK’s grid, is capable of handling a 3 GW power station at Wylfa, which could be very useful in the grand scheme of things.
This is also said in the Wikipedia entry for Wylfa power station.
On 4 April 2017, Horizon submitted a Site Licence Application to the Office for Nuclear Regulation. The scheme was extended to include a tunnel under the Menai Strait to carry the power cables to protect the conservation worth of the Strait and the Area of Outstanding Natural Beauty.
Horizon certainly seemed to try hard to get Wylfa B under construction.
As I said earlier, the Wylfa site could be an ideal site to connect offshore renewables to the grid.
Plan For New Nuclear Reactors At Wylfa And Trawsfynydd A Step Closer As Natural Resource Wales Looks At Designs
The title of this post, is the same as that of this article on nation.cymru.
These are the first two paragraphs.
Plans for new nuclear power stations at Trawsfynydd and Wylfa have taken a step closer after the UK Government asked government regulators to assess designs for the reactors.
Natural Resources Wales will be among those assessing the designs by Rolls-Royce, with both Wylfa and Trawsfynydd have been named as potential sites for housing them within the UK.
These are points about the reactors.
- They will cost £1.8 billion each.
- They are capable of powering a city the size of Cardiff, which has a population of about half-a-million.
- I’ve read elsewhere that the reactors are planned to have a nameplate capacity of 470 MW.
The article did mention, that the Nimbys were lining up.
The Wylfa Site
The original Wylfa power station was a Magnox nuclear station generating 980 MW, that was decommissioned in 2015.
This Google Map shows the location of the site on Anglesey.
This second Google Map shows the site in more detail.
The power station doesn’t appear to have had a rail link, but there is a railway line a few miles away, with sidings that might have been used to handle fuel flasks.
There has been a proposal for a hybrid plant consisting of a wind farm and small modular nuclear reactors, which is described in this Wikipedia section, where this is said.
In January 2021, Shearwater Energy presented plans for a hybrid plant, to consist of a wind farm and small modular reactors (SMRs), to be installed adjacent to the existing Wylfa power station but separate from the proposed Wylfa Newydd site. Shearwater has signed a memorandum of understanding with NuScale Power for the SMRs. The plant could start generation as early as 2027 and would ultimately produce up to 3 GW of electricity and power a hydrogen generation unit producing up to 3 million kg of hydrogen per year.
Note.
- Wylfa Newydd was a proposal by Hitachi to build a nuclear station on the site.
- Shearwater Energy is a UK developer of energy opportunities.
- NuScale Power is an American company with its own design of small modular nuclear reactor.
In Holyhead Hydrogen Hub Planned For Wales, I talked about hydrogen and the port of Holyhead.
The Trawsfynydd Site
The original Trawsfynydd power station was a Magnox nuclear station generating 470 MW, that was decommissioned in 1991.
This Google Map shows the location of the site in North Wales.
This second Google Map shows the site in more detail.
Note.
- The power station was built on the Northern shore of Llyn Trawsfynydd.
- Llyn Trawsfynydd is a man-made lake, that was built in the 1920s to supply water to the 24 MW Maentwrog hydro electric power station.
- There is a railway from near the site, that connects to the Conwy Valley Line at Blaenau Ffestiniog.
The Trawsfynydd site is a lot more than just a decommissioned Magnox power station.
Pumped Energy Storage In Snowdonia
Currently, there are two existing pumped storage in Snowdonia.
- Dinorwig power station, which is often called Electric Mountain, which has a capacity of 9.1 GWh.
- Ffestiniog power station, which has a capacity of around 1 GWh. If anybody has a better figure let me know!
A third scheme is under development at Glyn Rhonwy, which could have a capacity of 700 MWh.
Looking at the size of Llyn Trawsfynydd, I do wonder, if it could be the top lake of a future pumped storage scheme.
- Llyn Trawsfynydd, contains 40 million tonnes of water.
- There is a head of 190 metres.
That could give energy storage of 20 GWh. That sounds a lot of GWhs! But with two possible small modular nuclear reactors at possibly 500 MW each nearby and some help from windfarms, it could be filled within a day, if there is a suitable low-level reservoir.
Rolls-Royce And The Duisburg Container Terminal
In Rolls-Royce Makes Duisburg Container Terminal Climate Neutral With MTU Hydrogen Technology, I showed how Rolls-Royce and its subsidiary were providing an innovative climate neutral solution for Duisburg Container Terminal in Germany.
A North West Wales Powerhouse
Could Rolls-Royce be planning a Duisburg-style solution for North West Wales.
- Small modular nuclear reactors at Wylfa and Trawsfynydd.
- Hydrogen electrolysers to create hydrogen for the Port of Holyhead and heavy transport.
- Adequate pumped hydro storage for surplus energy.
But there could be little serious above-ground construction.
Conclusion
Something is awakening in North West Wales.
