French train manufacturer Alstom is set to become the first company to bring hydrogen trains to the UK with its plans to convert an existing fleet.

The company said the move was the “first substantive industry response” to calls by the Government for the removal of all diesel rolling stock by 2040.

Alstom will convert a fleet of Class 321 electric trains by fitting hydrogen tanks and fuel cells to power them. The fuel cell on the trains will produce electricity through a combination of hydrogen and oxygen to create water.

The electrical energy is then intermediately stored in batteries and the train is powered by an electrical traction drive. The only exhaust is steam and condensed water.

Alstom will carry out the work at its site in Widnes, Cheshire and will also partner on the project Eversholt Rail.

The move will be welcomed by the Government after Rail Minister Jo Johnson called in February for the removal of all diesel rolling stock by 2040.
