CNH2

A technology that combines hydrogen and oxygen in a clean, electrochemical process to generate power, releasing only water vapor as a byproduct.

Energy storage system used alongside the hydrogen fuel cell to enable operation on both electrified and non-electrified railway lines.

Advanced batteries used in the FCH2RAIL project's hybrid power system.

A European testing phase initiative aiming to enable electric trains to switch to emission-free hybrid operation when traveling through regions that are off the grid.

A modified CAF Civia Class 463 three-car electric multiple unit (EMU) equipped with hydrogen fuel cell systems and lithium-titanate batteries. The prototype will be capable of zero-emission operation and can run on both electrified and non-electrified railway lines.

A bi-mode hydrogen-powered train demonstrator based on a Renfe commuter train, featuring a hybrid fuel cell and battery power generation system. The vehicle can operate in electric mode on electrified track and hydrogen fuel cell mode on non-electrified sections, enabling zero-emission operation across diverse rail infrastructure.

A three-car electric multiple unit commonly used in Spanish commuter networks that will serve as the base platform for the hydrogen fuel cell train prototype.
