Talgo, Repsol, Sener, Tecnalia and CNH2, working together on the Hympulso project for hydrogen-powered rail transport.

Led by Talgo, the Hympulso project consortium is developing a pioneering prototype of a hybrid bimodal passenger train that will be powered by overhead lines when available, or by hydrogen and batteries on non-electrified routes. A multidisciplinary team from the National Hydrogen Center (CNH2) has recently designed, developed and installed a bespoke test bench capable of accommodating and testing the 600-kW module that will be mounted on the roof of the test vehicle. The test bench incorporates a green hydrogen supply system and an electronic load system that absorbs the power generated by the module, thus simulating the demand from the train’s engine. This validation phase has been key to commissioning all the equipment that makes up the fuel cell system and minimising potential issues during the subsequent phase of integrating it into the rail prototype. The Hympulso consortium partners are Talgo, Ingeteam, Optimus 3D, Repsol, Sener and Golendus, with collaboration from CNH2, Tecnalia and the University of Comillas. The Hympulso project is part of the PERTE program for renewable energy, renewable hydrogen and storage (ERHA).
