Germany Builds The World’s First Hydrogen Train Filling Station

The title of this post, is the same as that of this article on electrek.

Hydrogen Trains In Germany

The hydrogen filling station for trains is described under this heading.

This is the introductory paragraph.

The town of Bremervörde in Lower Saxony, Germany, has broken ground on the world’s first hydrogen filling station for passenger trains. Chemical company Linde will construct and operate the hydrogen filling station for the Lower Saxony Regional Transport Company.

It will provide approximately 1600 Kg of hydrogen per day.

The Supergroup Of ‘Green Energy’

This is a second section, which I find an interest sting concept.

These are the introductory paragraphs.

Oil giant Shell and Dutch utility Eneco have won the tender to build a super-hybrid offshore wind farm in the Netherlands. It will consist of two sites located 11.5 miles (18.5 km) off the west coast, near the town of Egmond aan Zee.

The Shell/Eneco consortium, CrossWind, will build the Hollandse Kust (noord) project. They will pair the offshore wind farms with floating solar facilities and short-duration batteries. It will also generate green hydrogen via an electrolyzer, according to GreenTech Media.

It will be operational in 2023 and have an output of 759 MW.

Beeching Reversal – South Fylde Line Passing Loop

This is one of the Beeching Reversal projects that the Government and Network Rail are proposing to reverse some of the Beeching cuts.

The Project

This project is described on this page on the web site of the Fylde MP; Mark Menzies, which is entitled Improving The South Fylde Rail Line.

The page lists that these improvements are needed.

Track And Stations

These improvements are listed for track and stations.

The bid involves laying around three miles of track between Lytham and St Annes stations, the creation of a new rail platform at Ansdell and Fairhaven Station, the installation of signalling along the line, and potential platform changes at Preston Station. There is scope for improvements to St Annes and Lytham Stations, should Network Rail decide it would rather include those stations within the passing loop – but that would be decided further along the process.

Services

The objective is to be able to run two trains per hour (tph) between Preston and Blackpool South stations.

Trains

Better trains are needed.

It certainly looks like the Pacers have already gone.

The Route

I shall describe the current route in this section.

Blackpool South Station

The Google Map shows Blackpool South station.

Note.

  1. Entrance to the station is from Waterloo Road, which runs East-West across the map.
  2. There are a pair of bus stops by the station entrance.
  3. There is a lot of car parking close to the station.
  4. I suspect that the single platform can hold a modern eighty-metre four-car train.
  5. This seventy-year-old has no difficulty waking to the football ground or the Blackpool trams from the station.

With two tph and some updated facilities, this would be a very useful station.

I suspect there is even space to add a second platform in the future, if that were felt to be necessary.

Blackpool Pleasure Beach Station

This Google Map shows Blackpool Please Beach station and the nearby Pleasure Beach.

We shouldn’t underestimate the importance of this station. One beautiful late summer Saturday, I was going to see Ipswich play at Blackpool and out of curiosity I had explored the train to Colne station. In those days a decade ago, Colne and Blackpool South was one service and the train from Colne was full of families, by the time it got to Preston. A large proportion, left the train at the Pleasure Beach.

The conductor told me, that the crowds, I had witnessed weren’t untypical.

Squires Gate Station and Blackpool Airport

This Google Map shows Squires Gate station and the nearby Blackpool Airport.

Blackpool Airport after a troubled few years seems to be finding a niche market, with a few business, commercial, offshore and training flights.

But I believe that airports like Blackpool in the future can develop another large niche – electric aviation.

Getting to places like Ireland, Northern Ireland, the Isle of Man and Wales by a nineteen-seat electric airliner will need the following.

  • As short a flight as possible.
  • Close to the coast would help.
  • Good public transport links.
  • Space for aircraft to be parked, whilst charging.
  • Plentiful supplies of renewable electricity. The over-300 MW Burbo Bank Wind Farm is not far away in Liverpool Bay and it will only be joined by more and larger wind farms.
  • Frequent public transport.

Blackpool Airport could tick all these boxes, with a thick green marker.

St. Annes-on-the-Sea Station

This Google Map shows St. Annes-on-the-Sea station.

Note.

  1. Blackpool is to the North-West and Preston is to the South-East
  2. St. Annes-on-the-Sea is one of those convenient single-platform stations, where you just walk in-and-out on the level.
  3. The passing loop would start on the Preston side of the bridge.

There would need to be no major infrastructure work at the station, although I would expect the facilities could do with a makeover.

Ansdell And Fairhaven Station

In Should The Blackpool South Branch Be Electrified?, I said this about improvements to Ansdell and Fairhaven station.

Ansdell and Fairhaven station is nearest to the course at Royal Lytham.

    • The Open Championship is a very important event on the golfing calendar.
    • Other important golfing events are also held on the course
    • Royal Lytham and St.Annes, last held the Open in 2012 and 2001. So it might come back to Royal Lytham in the mid-2020s.

Ansdell and Fairhaven station used to have two platforms, as described in Wikipedia.

The station was set out as an island platform with tracks on both faces until the singling of the line in the 1980s. Trains now only use the southern face. A disabled access ramp now covers the northern part of the station.

So could a rebuild of the station do the following?

    • Restore two platforms on an island at the station.
    • Put in full disabled access.
    • Create a passing loop.
    • Longer platforms might be a good idea.

This Google Map shows the station.

Note.

    1. The disabled ramp winding away.
    2. The platform is probably about a hundred metres long.
    3. It would appear that there is space at the far end to extend the platform.

I suspect that an ambitious architect with vision, could design a station that met all objectives.

It could be the best Championship Golf Course railway station in the world.

Lytham Station

This Google Map shows Lytham station.

Lytham station will be the Eastern end of the loop and it is likely, that the single-track will change to double at the Western end of the station.

As with St. Annes-on-the-Sea station, I suspect that a good makeover, will be all that will be needed.

Moss Side Station

This Google Map shows Moss Side station.

The only problem here is the level crossing, so do Network Rail want to remove it?

Kirkham And Wesham Station

This Google Map shows Kirkham and Wesham station.

There are three platforms, which from bottom to top on the map are.

  • Platform 1 – Trains to Blackpool South
  • Platform 2 – Trains to Blackpool North
  • Platform 3 – Trains to Preston

All platforms seem to be being electrified in these  pictures. that I took during construction.

Note.

  1. It can’t be described as a station, built down to a small budget.
  2. In the captions to the pictures, I’ve numbered the platforms from left to right.
  3. The last picture looks down Platform 1 and there is an electrification gantry at the Preston end.

Could this comprehensive electrification be so that trains to Blackpool North can use both Platforms 1 and 2?

  • This would allow overtaking of say a local train by a London express.
  • Trains could also be turned back in Platform 1, before the end of its journey, if there was a problem.
  • The electrification is also substantial enough for the longest Class 390 trains.
  • It could even accommodate a classic compatible High Speed Two train.

So does the last point, mean that Blackpool North station is a possible High Speed Two destination? Provided, the platforms at Blackpool North station are long enough, I think it does!

This Google Map shows Kirkham West Junction, where trains to Blackpool North and Blackpool South stations diverge.

Note.

  1. The electrification gantries and their shadows can be seen.
  2. Preston is to the South-East and the route is fully-electrified.
  3. Blackpool North is to the North-West and the route is fully-electrified.
  4. Blackpool South is to the West. The double-track becomes single before Moss Side station.

This picture shows the route going off to Blackpool South.

I took the picture from a train going to Blackpool North station.

So why are wires being run along the first few hundred metres of the Blackpool South Branch?

The Timetable

Currently, trains take the following times to do these journey legs.

  • Run between Ansdell and Fairhaven and Blackpool South stations – 12 minutes
  • Turnback at Blackpool South station – 3 minutes
  • Run between Blackpool South and Ansdell and Fairhaven stations – 11 minutes

As the trains will be running every thirty minutes and the three legs total twenty-six minutes, that means there’s four minutes float.

So hopefully, it should be easily stainable, by an experienced rail timetable creator.

The Trains

I have remarked that I find the electrification at Kirkham & Wesham station, both comprehensive and slightly unusual.

Could The Electrification Have Been Designed For Battery Electric Trains To Blackpool South Station?

But there is one very plausible reason for the electrification layout – The Blackpool South Branch has been designed, so that services on the branch can be rum using battery trains.

  • The distance between Kirkham & Wesham and Blackpool South stations is just over eleven miles.
  • So for a round trip a range of perhaps twenty-five miles on battery power would suffice.
  • There would also be a need for a few minutes of hotel power, whilst waiting at Blackpool South station.

These power needs are well within the capabilities of the average battery train.

  • Trains could be charged on the nine minute run  between Preston and Kirkham & Wesham stations.
  • Changeover between electrification and battery power would take place in Kirkham & Wesham station.

An ideal train would surely be CAF’s four-car battery electric version of the Class 331 train, which I wrote about in Northern’s Battery Plans.

  • According to an article in the March 2020 Edition of Modern Railways, with the same name, these trains will be working between Manchester Airport and Windermere.
  • Class 331 trains without batteries will be running to and from Blackpool North station.
  • Four-car trains are probably the right size for the route.

There would also probably be no need for a charging station at Blackpool South station, if trains could leave Kirkham & Wesham station with a full battery.

Where Would The Trains Terminate In The East?

These would be the obvious choices.

  • Blackburn – Where there is a convenient bay platform.
  • Colne – Where they used to terminate!
  • Preston – Where they do now!
  • Skipton – If the Skipton-Colne Link is built!

My money would be on Skipton, using a new Skipton-Colne Link, for the following reasons.

  • Politicians of all colours and roses are in favour.
  • Skipton has an electrified route to Leeds.
  • Skipton-Colne would be a valuable by-pass route during the building of Northern Powerhouse Rail.
  • Battery-powered trains would be ideal for Skipton-Colne.

Would A Battery Electric Train Handle Preston And Skipton?

I estimate that this route is forty-one miles, with a stiff rise from Rose Grove to Colne station.

So would a battery electric train be able to handle this distance?

Hitachi are talking 56 miles for their Regional Battery Train, so I suspect CAF would want and need to be competitive with a similar specification.

Perhaps the logical service would be to run between Leeds and Blackpool South.

  • The service would go via Preston, Blackburn, Burnley Central, Colne and Skipton.
  • Leeds and Skipton is electrified.
  • Preston and Kirkham & Wesham is electrified.
  • No extra chargers for trains would be needed.

The only new infrastructure needed would be the Skipton and Colne Link.

Electrification Between Preston And Blackburn

Consider.

  • In Colne – Skipton Reopening Moves Closer, I talked about the proposed Huncoat Rail Fright Terminal, that could be built North of Blackburn on the East Lancashire Line.
  • Blackburn is a major hub for passenger services.
  • An electrified Blackburn would allow Manchester and Clitheroe to be run by battery electric trains. Clitheroe is ten miles and Bolton is thirteen.
  • An electrified Blackburn would allow Blackburn and Manchester Victoria via the Todmorden Curve to be run by battery electric trains. The whole route is 39.5 miles.
  • It may be possible for battery electric trains to reach Leeds via Hebden Bridge, as it is only fifty miles away, which is within Hitachi’s range.
  • As the Blackburn area grows, there will be more pressure for a daily London service.
  • Some think, the Calderdale route should be electrified.
  • Preston and Blackburn stations are just twelves miles apart.
  • There is a multiple unit depot at Blackburn.
  • I also feel that battery electric trains fanning out from Blackburn, wouldn’t do the town’s image any harm.

For all these reasons, I wouldn’t be surprised to see a short stretch of electrification added between Preston and Blackburn.

Conclusion

I like this proposal and it could be a big asset to trains across the Pennines.

Keadby 3 Low-Carbon Power Station

This article on Business Live is entitled Huge Green Power Station Proposed By SSE As It Embraces Hydrogen And Carbon Capture.

SSE Thermal is working on a low-carbon 910 MW gas-fired power station to join Keadby and Keadby 2 power stations in a cluster near Scunthorpe.

A spokesman for SSE is quoted as saying they will not build the plant without a clear route to decarbonisation.

On this page of their web site,  SSE Thermal, say this about Keadby 3.

As part of our commitment to a net zero emissions future, Keadby 3 will only be built with a clear route to decarbonisation, either using hydrogen as a low-carbon fuel, or equipping it with post-combustion carbon capture technology. The project is at the early stages of development and no final investment decision has been made.

It should also be noted that SSE Renewables have also built a wind farm at Keadby. The web site describes it like this.

Keadby Wind Farm is England’s largest onshore wind farm. This 68MW renewable energy generation site can power approximately 57,000 homes.

There are a lot of good intentions here and I think that SSE haven’t disclosed the full picture.

It would seem inefficient to use hydrogen to power a gas-fired power station to achieve zero-carbon power generation.

  • If you are using hydrogen created from steam reforming of methane, this creates a lot of carbon-dioxide.
  • If you are using green hydrogen produced by electrolysis, then, why don’t you store the electricity in a battery?

Perhaps, SSE are trying out a new process?

This Google Map shows the area of Keadby to the West of Scunthorpe.

Note.

The River Trent meandering through the area.

  1. Althorpe station is in the bend of the River,
  2. I’m fairly certain, that I remember an old airfield in the area.
  3. Keadby power station is a bit to the North of the waterway running West from the River and close to where the railway crosses the waterway.

This second Google Map shows a close-up of the power station.

This visualisation from SSE Thermal shows how the site might look in the future.

For me the interesting location is the village of Althorpe, where C and myself had friends.

They were always getting tourists arriving in the village looking for Princess Diana’s grave!

Carbon Capture And Storage At Keadby

If SSE have three large power stations at Keadby, a shared carbon capture and storage system could be worthwhile.

  • There are numerous gas fields in the area and a big gas terminal at Theddlethorpe, to where they all connect.
  • I was surprised to see, that one of thee fields; Saltfleetby is owned by President Putin’s favourite gas company; Gazprom.
  • Some of these fields are actually on-shore.
  • The power stations probably get their gas from the same terminal.

Some of these gas fields that connect to Theddlethorpe could be suitable for storing the carbon dioxide.

As there is masses of space at Keadby, I can see more gas-fired power stations being built at Keadby.

All would feed into the same carbon capture and storage system.

If gas was needed to be imported in a liquified form, there is the Port of Immingham nearby.

Absorption Of Carbon Dioxide By Horticulture

Consider.

  • Increasingly, horticulture is getting more automated and efficient.
  • Automatic harvesters are being developed for crops like tomatoes and strawberries.
  • Instead of storing the carbon-dioxide in worked-out gas fields, it can also be fed directly to fruit and vegetables that are being grown in greenhouses.
  • Keadby is surrounded by the flat lands of Lincolnshire.

How long will it be before we see tomatoes, strawberries, peppers and cucumbers labelled as British zero-carbon products?

Offshore Hydrogen

I’ll repeat what I said in ITM Power and Ørsted: Wind Turbine Electrolyser Integration.

This is from a press release from ITM Power, which has the same title as the linked article.

This is the introductory paragraph.

ITM Power (AIM: ITM), the energy storage and clean fuel company, is pleased to share details of a short project sponsored by the Department for Business, Energy & Industrial Strategy (BEIS), in late 2019, entitled ‘Hydrogen supply competition’, ITM Power and Ørsted proposed the following:  an electrolyser placed at the wind turbine e.g. in the tower or very near it, directly electrically connected to the DC link in the wind turbine, with appropriate power flow control and water supplied to it. This may represent a better design concept for bulk hydrogen production as opposed to, for instance, remotely located electrolysers at a terminal or platform, away from the wind turbine generator, due to reduced costs and energy losses.
Some points from the remainder of the press release.

  • Costs can be saved as hydrogen pipes are more affordable than under-water power cables.
  • The proposed design reduced the need for AC rectification.

After reading the press release, it sounds like the two companies are performing a serious re-think on how wind turbines and their links to get energy on-shore are designed.

  • Will they be using redundant gas pipes to bring the hydrogen ashore?
  • Will the hydrogen come ashore at Theddlethorpe and use the existing gas network to get to Keadby?

It sounds inefficient, but then the steelworks at Scunthorpe will probably want masses of hydrogen for carbon-free steel making and processing.

Boosting Power Station Efficiency

There is also a section in the Wikipedia entry for Combined Cycle Power Plant called Boosting Efficiency, where this is said.

The efficiency of CCGT and GT can be boosted by pre-cooling combustion air. This is practised in hot climates and also has the effect of increasing power output. This is achieved by evaporative cooling of water using a moist matrix placed in front of the turbine, or by using Ice storage air conditioning. The latter has the advantage of greater improvements due to the lower temperatures available. Furthermore, ice storage can be used as a means of load control or load shifting since ice can be made during periods of low power demand and, potentially in the future the anticipated high availability of other resources such as renewables during certain periods.

So is the location of the site by the Trent, important because of all that cold water?

Or will they use surplus power from the wind farm to create ice?

The Proposed North Sea Wind Power Hub

The North Sea Wind Power Hub is a proposed energy island complex on the Eastern part of the Dogger Bank.

  • The Dutch, Germans and Danes are leading the project.
  • Along with the Belgians, we have been asked to join.
  • Some reporting on the Hub has shown, airstrips in the middle of the complex to bring the workforce to the site.
  • A Dutch report, says that as much as 110 GW of wind power could be developed by 2050.
  • We are also looking at installing wind farms on our section of the Dogger Bank.

Geography says, that one of the most convenient locations to bring all this electricity or hydrogen gas ashore is North Lincolnshire

A Very Large Battery

I would also put a very large battery on the site at Keadby.

One of Highview Power‘s proposed 1 GWh CRYOBatteries would be a good start. This will be four times the size of the 250 MWh CRYOBattery, which the company is currently designing and building at Carrington in Greater Manchester.

Conclusion

The three power stations at Keadby are the following sizes

  • Keadby 1 – 734 MW
  • Keadby 2 – 803.7 MW
  • Keadby 3 – 010 MW

This adds up to a total of 2447.7 MW. And if they fit carbon capture and storage it will be zero-carbon.

Note.

  • Hinckley Point C is only 3200 MW and will cost around £20 billion or £6.25 billion per GW.
  • Keadby 2 power station is quoted as costing £350 million. or £0.44 billion per GW.

These figures don’t include the cost of carbon capture and storage, but they do show the relatively high cost of nuclear.

61GW Renewables And Storage Pipeline Could Bring In £125bn To Economy

I did think about calling this post something like.

  • Do You Like Large Numbers?
  • My Calculator Just Blew Up!
  • I Don’t Believe It!
  • No Wonder Rishi Sunak Has A Smile On His Face!

But I’ll use my normal introduction for this type of post!

The title of this post, is the same as that on this article of Current News.

This is the introductory paragraph.

The UK currently has a pipeline of 61GW of renewables and storage that if developed could bring in £125 billion to the UK economy.

The article also says that this pipeline could provide 200,000 jobs.

So where will this massive 61 GW of electricity come from?

  • Off-shore Wind – 31.7 GW
  • On-shore Wind – 11.9 GW
  • Solar PV – 8.6 GW
  • Storage – 8.5 GW

Where is the Nuclear Option?

iThe article also says that 18 GW of these projects are Shovel-Ready.

The figures come from UK trade association; Regen, whose Chief |Executive is the appropriately named; Merlin Hyman.

The page on the Regen web site, which is entitled Unlock Renewables For A Green Recovery,  is the original document on which the Current News article is based.

Regen want three things from the Government, in return for creating all this renewable electricity capacity.

  1. Publish an Energy White Paper putting the UK on course for a flexible power system based on renewables and storage.
    Commit to annual Contracts for Difference auctions to give investors confidence.
    End the anti onshore wind policies in the English planning regime.

Some will not like the third condition.

I must go now, as I must go down the Chinese-owned Lucky Electronics Shop on Dalston Kingsland High Street to get a calculator with more digits to replace the one that blew up!

What Does the Future of Offshore Wind Energy Look Like?

The title of this post, is the same as that of this article on Real Clear Energy.

These topics are covered.

  • Improved efficiency
  • Aerodynamic blades
  • Sturdiness and durability
  • Big data, the cloud and artificial intelligence
  • Drones
  • Floating turbines and deeper waters
  • Complicated coastal climate zones of which North America has eight.

Some topics weren’t covered.

The author finishes with this statement.

The integration of wind energy, in any form, can ultimately benefit all 50 states in the US by 2050 if it starts now.

In 1962, Bob Dylan, wrote this famous phrase.

The answer, my friend, is blowin’ in the wind.

Fifty-eight years later he’s been proven right, in a big way!

Ryse Hydrogen Wants To Make The North East Of Scotland A World Leader In Hydrogen

The title of this post, is the same as that of this article on H2 View.

This is the introductory paragraph.

Ryse Hydrogen has pledged to work with the Scottish Government and local authorities to make the North East of Scotland a world leader in hydrogen.

I think this is both a laudable and a very sensible aim.

  • Large offshore wind farms are being built both around Aberdeen and the Far North of Scotland.
  • Production of hydrogen is a sensible way to use spare renewable electricity.
  • That area of Scotland is not short of wind.
  • Aberdeen will be taking delivery of hydrogen buses later this year.
  • With their experience of the oil industry, there would not be a shortage of people with the necessary expertise.

The article also details Jo Bamford’s plans for hydrogen buses.

Newcomer Broad Reach Power To Deploy Increasingly Large Battery Systems In Texas

The title of this post is the same as that of this article on Energy Storage News.

This is the introductory paragraph.

US-based independent power producer (IPP) Broad Reach Power has said it will build 15 projects in Texas in 2020, each of them just under 10MW / 10MWh, with construction on six of them set to begin this summer.

The article then goes on to describe the electricity industry in Texas and where the battery storage fits in.

It’s all a far cry from the Texas portrayed in soaps like Dallas.

Wind Power In Texas

Wind Power in Texas has its own Wikipedia entry and this is the first paragraph.

Wind power in Texas consists of over 40 wind farms, which together have a total nameplate capacity of over 28,000 MW (as of 2019). If Texas were a country, it would rank fifth in the world: The installed wind capacity in Texas exceeds installed wind capacity in all countries but China, the United States, Germany and India. Texas produces the most wind power of any U.S. state.

But then everything in Texas, is famed as being the biggest in the world.

Their installed capacity of 28 GW compares with 17.64 GW of installed wind power in the UK.

Solar Power In Texas

Solar Power in Texas also has its own Wikipedia entry and this is the first paragraph.

Solar power in Texas, along with wind power, has the potential to allow Texas to remain an energy-exporting state over the long term. The western portion of the state especially has abundant open land areas, with some of the greatest solar and wind potential in the country. Development activities there are also encouraged by relatively simple permitting and significant available transmission capacity.

The Wikipedia entry also says that in 2019, Texas had 4.32 GW of installed solar power.

By comparison, the UK has 8.1 GW of installed solar power. Who’d have thought that?

As Texas is 2.87 times geographically larger than the UK, if Texas had the same solar panel density as the UK, Texas would have an installed capacity of 23.2 GW.

The Need For Energy Storage In Texas

With all this installed wind and solar energy in Texas and its potential for expansion, there would appear to a massive demand for energy storage in the state.

Conclusion

What would JR think?

Norway Announces $384.5m Clean Energy Fund To Aid In Covid-19 Recovery

The title of this post, is the same as that of this article on Power Technology.

These are the first one-and-a-half paragraphs.

Last week, Norway announced plans to fund a “green transition package”, investing $384.5m into sustainable power and infrastructure to help the country’s economy and productivity post-Covid-19.

The fund will be used to support a range of initiatives, including investments in hydrogen power and battery storage technology, building offshore wind infrastructure, and renovations to new and existing buildings, as Norway looks to reach the Paris Climate Agreement target of limiting global temperature rise to less than two degrees by 2050.

Perhaps we should follow Norway’s lead.

Sizewell C: Nuclear Power Station Plans For Suffolk Submitted

The title of this post, is the same as that as this article on the BBC.

A few points from the article.

  • It will provide enough electricity for six million homes.
  • It will create 25,000 jobs during construction.
  • Sizewell C will be a near replica to Hinckley Point C.
  • It will generate 3.2 GW of electricity.
  • It will be low-carbon electricity.

As a well-read and experienced engineer, I am not against the technologies of nuclear power.

But I do think, by the time it is completed , other technologies like wind and energy storage will be much better value. They will also be more flexible and easier to expand, should we get our energy forecasts wrong.

  • We will see higher power and more efficient wind farms, further out in the North Sea.
  • Massive energy storage systems, based on improved pumped storage technology and using new technology from companies like Highview Power, Zinc8 and others will be built.
  • Wind and solar power an energy storage are much easier to fund and financial institutions like L & G, Aberdeen Standard and Aviva have invested in the past for our future pensions.
  • If you want to go nuclear, small modular reactors, look to be much better value in the longer term.
  • I also don’t like the involvement of the Chinese in the project. History tells me, that all pandemics seem to start in the country!

It is my view that the biggest mistake we made in this country over energy was not to built the Severn Barrage.

My preferred design would be based on the ideas of Sir Frederick Snow.

There would have been a high and a low lake, either side of a central spine, behind an outer barrage.

  • Reversible turbines and pumps between the lakes would both generate and store electricity.
  • When proposed in the 1970s, it would have generated ten percent of the UK’s electricity.
  • A new road and rail crossing of the Severn, could have been built into the outer barrage.
  • A lock would have provided access for shipping.
  • It would have controlled the periodic, regular and often devastating flooding of the River Severn.

Some versions of the original design, even incorporated an international airport.

  • The runways would be in the right direction for the prevailing wind, with regard to take-off and landing.
  • Take-off would be over open sea.
  • High speed trains could speed travellers to and from London on an updated Great Western Railway.

I believe a modern design could be even better.

  • The central spine and the outer barrage would be the foundations for a large wind farm.
  • There would also be a large number of powerful floating wind turbines to the West of the outer barrage in the Severn Estuary.
  • A giant electrolyser on the central spine would produce hydrogen, that could be used to decarbonise the UK’s gas network.
  • A power interconnector could be built into the outer barrage to connect Wales to the nuclear power stations at Hinckley :Point.
  • A cluster of small nuclear reactors could be built on the central spine.
  • In the intervening fifty years, we have probably learned how to build a barrage like this, so that it can benefit birds and other wildlife.

I believe, it will never be too late to build a Severn Barrage.

‘World First’: SGN Launches Bid For 300 Green Hydrogen Homes Project In Fife

This title of this post, is the same as that of this article on Business Green.

This is the introductory paragraph.

Around 300 homes in Scotland could soon have their heating and cooking powered by green hydrogen produced from renewable electricity under proposals for “the world’s first green hydrogen-to-homes network” unveiled today by SGN.

A few points from the article.

  • Construction could start in the winter of 2020/21.
  • The project will take two or three years.
  • The modified houses appear to be in Levenmouth.
  • The project has been dubbed H100 Fife.
  • The hydrogen will be produced by electrolysis using electricity generated by offshore wind.

The article also gives a round-up of the state of hydrogen in the UK.

Could This Have Other Implications For Levenmouth?

In Scottish Government Approve £75m Levenmouth Rail Link, I discussed the rebuilding of the Levenmouth Rail Link.

I suggested that the route could be run by Hitachi Class 385 trains with batteries, which Hitachi have stated are being developed. I covered the trains in more detail in Hitachi Plans To Run ScotRail Class 385 EMUs Beyond The Wires.

If there were to be a source of hydrogen at Levenmouth, could hydrogen-powered trains be used on the route?

The Levenmouth Rail link could be a prototype for other short rail links in Scotland.
