Hydrogen systems are a zero-emission alternative for non-electrified lines, where diesel trains now run.
Talgo presented his hydrogen-based train propulsion system, a sustainable, innovative and energy-efficient alternative to replace polluting diesel trains.
The system is a modular solution that allows its installation in all types of trains, but it was specially designed for the Vittal Cercanías y Media Distancia platform.
This new system use fuel cells which supply energy to the electric motors of trains.
It is powered by renewable energy sources, such as solar or wind power, which produce hydrogen which is stored and later used to power propulsion systems based on hydrogen cells.
This system is supplemented by batteries which increase the acceleration available at start-up, take advantage of the braking of the train to recharge.
Unlike battery systems used in the automotive industry, hydrogen (H2) technology is presented as a solution to the needs of heavy transport and, in particular, rail lines that do not have catenary electrification systems. , and which, to this day, depend on trains powered by diesel engines.
The hydrogen system designed by Talgo makes it possible to “electrify” the lines of the conventional network without requiring costly and time-consuming adaptation work, eliminate the use of fossil fuels.
The first road tests will be carried out on the Extremadura lines in the fourth quarter of 2021.
Talgo SA is a leader in the design, manufacture and maintenance of light high speed trains with an industrial presence in seven countries.
