Talgo is a spanish manufacturer of intercity, standard, and high speed passenger trains.
Talgo has announced the calendar for the manufacture and commissioning of its future hydrogen train, which foresees a first phase of tests to be carried out during 2021 and the subsequent installation of this technology in the new trains between 2022 and 2023.
The railway manufacturer has presented the details of this “green, innovative and efficient” technology, which will replace diesel locomotives, during the event ‘Renewable hydrogen: an opportunity for Spain’, organized by the Ministry for the Ecological Transition and the Demographic Challenge .
In addition to the planned schedule, the company has also revealed that the hydrogen train will bear the name ‘Talgo Vittal-One’, with ‘One’ being the reference to the place that hydrogen occupies in the periodic table, number one.
“Green hydrogen is no longer the future, it is a reality. The launch of hydrogen trains such as 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 its CEO, José María Oriol.
The company explains that this system is configured as a modular solution that allows it to be installed in all types of trains, as well as in conversion from diesel to hydrogen, but that it has been specifically designed for the Vittal Cercanías and Media Distancia platform, with which Talgo attends various bidding processes in Spain and other countries.
Specifically, the system uses hydrogen batteries that provide energy to the train’s electric motors and is fed 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 with 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 (H2) technology is presented as the answer to the needs of heavy transport and, in particular, of those railway lines that do not have electrification systems through catenary, and that As of today, they depend on trains powered by diesel engines.
The hydrogen system designed by Talgo thus makes it possible to electrify the lines of the conventional network “without the need for costly and lengthy adaptation works, dispensing with fossil fuels.”
