Highland Council Forges Green Hydrogen Pact
The title of this post, is the same as that of this article on renews.biz.
These are the first two paragraphs.
Getech subsidiary H2 Green has signed a memorandum of understanding (MoU) with the Highland Council in Scotland aimed at creating a regional network of green hydrogen hubs across the Scottish Highlands.
Under the terms of the MoU, H2 Green and the Highland Council will produce a regional plan to develop a network of green hydrogen hubs at optimal locations across the region.
The first hub appears to be in Inverness, as I wrote in Hydrogen Hub Plan Will Cut Transport Sector Emissions In The Highlands.
But that is only the start.
- Green hydrogen will be used in transport in the Highlands.
- By-products like oxygen and heat will be distributed.
- Delivery of Highland decarbonisation will be planned.
- SGN Commercial Services will service large-volume customers.
- Agreements are in place for Eversholt Rail to deploy their hydrogen-powered trains on the Far North and West Highland Lines of Scotland.
This statement from Jonathan Copus of Getech, sums up the objectives of the hydrogen project.
These activities combined with the Highland Council initiative are set to establish the Highlands as the leading UK-centre for decarbonisation and innovation; they will also support job creation, deliver energy security and provide a sustainable path for the region’s net zero transition.
I believe that a similar approach could be taken in other parts of the UK. Cornwall, East Anglia, Lincolnshire, much of Wales and the Borderlands between England and Scotland come to mind.
Each region will probably, decarbonise slightly differently and each will develop more and more innovative ways to use the hydrogen.
Conclusion
Hydrogen will play a large part in the decarbonisation of the UK.
Sydenham Hill Station – 11th March 2022
When I wrote Advance Warning Of Brixton To Beckenham Junction Rail Closure In July, I realised I’d never been to Sydenham Hill station.
So this morning, I went to have a look.
Note.
- Penge tunnel doesn’t look to be the widest of tunnels.
- Few if any freight trains, seem to use the route.
- Sydenham Hill station, certainly isn’t one of the grandest of stations.
I doubt there’s much work to do at the station, during the closure.
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.
