Alstom and Eversholt announce hydrogen train for the UK

The design of a hydrogen-powered train for the UK market has been unveiled by manufacturer Alstom and rolling stock leasing company Eversholt Rail.

The new ‘Breeze’ will be a conversion of an existing Class 321 train, reengineered to create a clean train that produces only water vapour as its exhaust, with no harmful emissions at all. Hydrogen is used to generate electricity using a fuel cell, where the gas is combined with oxygen from the atmosphere to produce energy and water, and that energy then powers the train through conventional traction motors.

The ‘new’ trains could run across the UK as early as 2022.

Alstom has a wealth of experience with hydrogen-powered trains. The company’s Coradia iLint began operations in September 2018 in Germany, where they now operate in regular passenger service on a daily basis.

Although the iLint is a newly built train, the conversion of the Class 321 to hydrogen power will use similar technology. The innovative technical solution is the first to allow a hydrogen train to fit within the standard UK loading gauge, and it will also create more space for passengers than the trains they are intended to replace.

The Alstom facility in Widnes will manage the conversion of the Breeze trains, creating high quality engineering jobs in this new sector. The proven and reliable Class 321 is an excellent fit in terms of characteristics, fleet size and availability for conversion to a Hydrogen Multiple Unit (HMU).

Commenting on the announcement, Rail Minister Andrew Jones MP said: “Hydrogen train technology is an exciting innovation which has the potential to transform our railway, making journeys cleaner and greener by cutting CO2 emissions even further. We are working with industry to establish how hydrogen trains can play an important part in the future, delivering better services on rural and inter-urban routes.”

In addition to the existing fleet in Germany and this announcement for the UK, there is growing interest in Alstom’s hydrogen technology worldwide, including in France where the President of the Occitanie region, Carole Delga, recently announced a proposal to introduce the technology on trains there.

SPECIALIST AREAS Rolling stock, mechanical equipment, project reports, executive interviewsNigel Wordsworth graduated with an honours degree in Mechanical Engineering from Nottingham University, after which he joined the American aerospace and industrial fastener group SPS Technologies. After a short time at the research laboratories in Pennsylvania, USA, Nigel became responsible for applications engineering to industry in the UK and Western Europe. At this time he advised on various engineering projects, from Formula 1 to machine tools, including a particularly problematic area of bogie design for the HST. A move to the power generation and offshore oil supply sector followed as Nigel became director of Entwistle-Sandiacre, a subsidiary of the Australian-owned group Aurora plc. At the same time, Nigel spent ten years as a Technical Commissioner with the RAC Motor Sports Association, responsible for drafting and enforcing technical regulations for national and international motor racing series. Joining Rail Engineer in 2008, Nigel’s first assignment was a report on new three-dimensional mobile mapping and surveying equipment, swiftly followed by a look at vegetation control machinery. He continues to write on a variety of topics for most issues.

  1. Hydrogen powered Class 321 (or classified as Class 7xx) could be ideal to operate in Wales and England. Such as in Southwest England, West Midlands, East Midlands, North of England, North Wales, Southeast England (including London) and parts of Scotland including Highlands, Scottish Borders, Glasgow area and Fife.
