Talgo announced the manufacturing and commissioning schedule for the future hydrogen-powered train, a green, innovative and efficient alternative to replace diesel locomotives, which will be ready in 2023. The train will be named Talgo Vittal-One, One being the reference to the hydrogen’s place on the periodic table. The details were presented during the act “Renewable hydrogen: an opportunity for Spain”, organized by the Ministry for the Ecological Transition and the Demographic Challenge.
On-track hydrogen technology validation tests will be carried out in a first phase in 2021. After its validation, the technology will be installed on the new train in a second manufacturing phase that will take place between 2021 and 2023.
“Green hydrogen is no longer the future, it is a reality. The start-up of hydrogen trains like the one Talgo is developing will improve mobility in our country hand in hand with the environment, since it will make it possible to take advantage of non-electrified Spanish lines, while reducing the carbon footprint,” said the CEO of Talgo, José María Oriol.
This system is configured as a modular solution that allows its installation in all types of trains, as well as in conversions from diesel to hydrogen, but it was designed specifically for the Vittal commuter and medium-distance platform, with which Talgo attends various processes of tender in Spain and other countries.
This innovative system uses hydrogen batteries that provide energy to the train’s electric motors. It is powered by renewable energy sources, such as solar photovoltaic or wind, which produce hydrogen that is stored and later used to power advanced propulsion systems based on fuel cells, such as the one designed by Talgo. The system is complemented by batteries that increase the acceleration available at starts, taking advantage of the train braking to recharge.
Unlike extended battery systems in the automotive industry, hydrogen technology is presented as the logical answer to the needs of heavy transport and, in particular, those railway lines that do not have electrification systems through catenary, and that currently depend of trains powered by diesel engines.
