Talgo Presents Its Hydrogen Propulsion System

Talgo has presented its hydrogen technology for trains at the H2 Conference in Don Bentio, Badajoz, as part of efforts to examine how hydrogen technologies could be deployed in the Iberian Southwest.

Talgo specifically chose the autonomous region of Extremadura to present its hydrogen solution because it recognises the region’s efforts to innovate and accelerate a transition to completely decarbonised transport networks. Furthermore, Talgo believes Extremadura has exhibited a more determined commitment to the generation and regeneration of industrial chains based on the local production of hydrogen.

The first validation tests on track featuring Talgo’s propulsion system will take place on railway lines in the Extremadura region in the fourth quarter of 2021. It will be the first prototype of this kind in Spain.

Talgo has configured its system in such a way as to be modular, allowing it to be installed on all kinds of trains. However, Talgo has designed it with the suburban Cercanías and the regional Media Distancia platforms in mind.

The hydrogen batteries deliver energy to the train’s electric motors. The hydrogen can be sourced from renewable methods such as solar or wind energy in order to be environmentally friendly. The hydrogen generated by these means can be stored and then used to power the fuel cell propulsion system. Talgo’s system is complemented by batteries to provide additional power for acceleration when starting, which make use of the train’s braking energy to recharge.
