Hexagon Purus has secured an order to supply high-pressure cylinders to Talgo for its first zero-emission hydrogen prototype train in Spain.

A manufacturer of standard, intercity and high-speed passenger trains, Talgo’s first green hydrogen train, Vittal-One, will be made and deployed in Spain. Consequently, it will also serve as a blueprint for the implementation of hydrogen technologies in the Iberian Southwest.

Hexagon Purus’ hydrogen cylinders will be supplied in the second half of this year.

Hexagon Purus executive vice-president Michael Kleschinski said: “There are more than 10,000 diesel trains in operation across Europe that will need to be replaced over the next 15 years. For distances between 400km and 800km, hydrogen-powered trains are a smart solution to reduce local emissions without incurring the high cost of electrifying the tracks. We are excited to help develop the solutions needed for this ground-breaking move in public transit.”

For decarbonising train lines and decreasing harmful greenhouse gas emissions, replacing diesel trains with hydrogen-powered trains is a cost-effective option.

As a clean and safe energy carrier, hydrogen can be used as a fuel in many applications.

The replacement process, which requires only limited track overhauls, can be done by retrofitting existing diesel locomotives.

Hexagon Purus stated that this will be beneficial for rural parts where there are more distances to cover, but fewer passengers to justify the overhead.

Talgo innovation director Emilio García said: “Green hydrogen is no longer the future, it is a reality. The start-up of hydrogen trains such as Talgo’s Vittal-One will improve mobility in our country hand-in-hand with the environment, as it will make it possible to take advantage of the non-electrified Spanish lines while reducing the carbon footprint.”

Hexagon Purus’ durable, lightweight, all-composite Type 4 pressure vessel technology assists a variety of mobility and storage applications in the hydrogen industry.

This will be Hexagon Purus’ third hydrogen rail project since the launch of the world’s first hydrogen-powered commuter train in 2018.
