Anglesey Hydrogen Can Bridge UK’s Energy Gap Says Economics Expert

The title of this post, is the same as that of this article on the University of Bangor web site.

This is the sub title.

Anglesey can become a UK leader in hydrogen energy technology, cleaning up the transport sector and creating high quality jobs across North Wales, according to a leading Welsh economic expert.

The University of Bangor is a respected university, that goes back to the nineteenth century.

But for Liverpool giving me an unconditional offer, as Bangor was one of the universities on my UCCA form, I could have studied in the North-West corner of Wales.

After a resume of where we are with hydrogen in the world, Dr. Edward Jones of Bangor University outlines how North West Wales can be turned into a hydrogen hub, to join similar hubs at Deeside in Flintshire and at Milford Haven in Pembrokeshire.

This is a paragraph of the article.

Dr Jones believes hydrogen could also hold the key to powering transport in future through a Welsh invention from the 19th century (the hydrogen fuel cell was developed in Swansea by William Grove in 1842).

William Grove was an interesting lawyer and scientist.

Dr. Jones would appear to be very much in favour of using hydrogen to take Wales forward to being zero-carbon in 2050.

I have written a few posts about the transformation of Anglesey and North West Wales, as Wales moves towards this goal. I also have some other thoughts of my own.

Holyhead Hydrogen Hub

This is happening and I wrote about it in Holyhead Hydrogen Hub Planned For Wales.

High Speed Two To Holyhead

I believe this could be a way to create a zero-carbon route between London and Dublin in under five hours and I wrote about it in Could High Speed Two Serve Holyhead?.

  • London and Holyhead in a battery-equipped High Speed Two Classic-Compatible train should be under three hours.
  • A single High Speed Two Classic-Compatible train would run between London and Holyhead, with a passenger capacity of around five hundred. It would probably split and join with another service at Crewe.
  • Discontinuous electrification would be provided along the North Wales Coast Line.
  • The trains could call at Old Oak Common, Birmingham Interchange, Chester, Crewe, Llandudno Junction and Bangor.

A High Speed catamaran would speed passengers between Holyhead and Dublin in under two hours.

Hydrogen-Powered Catamarans From Holyhead

The dynamics of a diesel-powered high speed catamaran are well-proven, with some large craft transporting passengers and vehicles on sea crossings all over the world.

Type “hydrogen-powered high speed catamaran” into Google and you get several hits to research and development projects, but no-one appears to have taken a large high speed craft and converted it to hydrogen.

But I do believe that someone somewhere is developing a hydrogen-powered catamaran with something like the following specification.

  • 200 passengers
  • 100-mile range
  • 60 knot operating speed.

The HSC Francisco is a high speed craft that plies between Buenos Aires and Montevideo carrying over a thousand passengers and a hundred cars at 58 knots. It is powered by gas-turbine engines running on liquified natural gas.

I believe I’m not asking for the impossible.

Anglesey Airport As A Zero-Carbon Airport

Anglesey Airport uses part of RAF Valley and has hosted services to Cardiff.

This Google Map shows the runways of RAF Valley.


  1. The longest runway 14/32 is over two thousand metres long.
  2. Rhosneigr station in the South East corner of the map.
  3. The facilities of Anglesey Airport to the North-East of the runways.

The railway forms the border of the airport, as this second Google map shows.

The railway is straight as it passes the Airport and there would be space for a two-hundred metre bi-directional step-free platform for passengers for the Airport.

Airbus are proposing a hydrogen-powered ZEROe Turbofan.

If you think it looks familiar, I believe that Airbus are proposing to develop the aircraft out of the current Airbus A320neo.

  • The capacity will be up to 200 passengers.
  • The range will be up to 2000 miles.
  • Dublin and Anglesey Airports are just 71.5 miles apart.
  • The cruising speed of Mach 0.78 would be irrelevant on this route, as it would probably fly a route to minimise noise.

The plane would probably be able to do several trips between Anglesey and Dublin without refuelling.

As the Port of Holyhead is developing a hydrogen infrastructure, I suspect that to provide hydrogen refuelling at Anglesey Airport would be possible.

I believe that by combining hydrogen-powered aircraft with battery-electric trains, some difficult sea crossings can be made carbon-free.

I believe that Anglesey Airport could be key to a zero-carbon London and Ireland service.

  • Airbus are also proposing a 100-seat ZEROe Turboprop.
  • Belfast, Cork, Derry and Shannon would also be in range.

Flights could also continue to and from Cardiff.

Reopening The Anglesey Central Railway

This has been proposed as a Beeching Reversal project.

I wrote about it in Reopening The Anglesey Central Railway.

It could be reopened as a zero-carbon railway.


There is a lot of scope to use hydrogen in North West Wales and Anglesey.

Reopening The Anglesey Central Railway

Note that this post was updated in October 2021.

The Anglesey Central Railway is a disused branch railway, where the track-bed is intact although overgrown, that runs across the Island of Anglesey from the North Wales Coast Line to the port town of Amlwch.

It carried freight until 1993 and is one of those remote lines, where a case can be made for reopening., using simple station designs and affordable trains.

On its route it serves the County Town of Llangefni and these stations are proposed, either on the branch or the island

With the existing stations on the North Wales Coast Line, a useful local railway could be created.

But would it be value for money?

These are a few of my thoughts.

Bangor Station

Bangor station looks like the ideal place to terminate the service from the Anglesey Central Railway.

This Google Map shows Bangor station.


  1. Anglesey is to the West.
  2. There are four tracks through the station. This will allow trains to overtake.
  3. Only the outside two tracks have platforms.
  4. The platforms are long enough to handle at least a two-hundred metre long train. They could even be long enough to handle a pair of Aventi West Coast’s new Class 805 trains, which would be 260 metres long.
  5. There are a couple of Anglesey-facing sidings, which probably could be converted into at least one bay platform.
  6. I suspect in a city like Bangor, there is probably enough electric power to provide charging facilities in an Anglesey-facing bay platform.

I can’t see any problems with terminating Anglesey Central Railway services at Bangor.

Battery-Electric Trains Between Bangor And Amlwch


  • Bangor and Amlwch would be around 25 miles.
  • Modern battery-electric trains have a range of up to 80 miles.
  • Battery-electric trains can fully recharge in 15 minutes.

This means that with charging facilities at Bangor, modern battery-electric trains could handle a return journey between Bangor and Amlwch.

I suspect that a very acceptable two trains per hour (tph) should be possible.

Hydrogen Trains Between Bangor And Amlwch

These would also be possible, once a refuelling strategy has been decided.
