Talgo chooses Extremadura to present its innovative hydrogen propulsion system
press release
-
It will be the first prototype in Spain
-
Hydrogen technology is an emission-free alternative for non-electrified lines, where diesel trains are now operating
-
The system has been presented in Don Benido, Badajoz, within the framework of the SOI H2 Conference, on the possibilities that hydrogen technologies present in the Southwest of the Iberian Peninsula (SoI)

Hydrogen-powered trains
This innovative system uses hydrogen batteries that provide the energy for 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 then used to power fuel cell-based propulsion systems, such as the one designed by Talgo. The system is complemented by batteries that increase the speed of the train when it starts, taking advantage of the braking system to recharge it.
Unlike the extended battery systems in the automotive industry, hydrogen (H2) technology is the logical answer to the needs of heavy transport and, in particular, of those railway lines that do not have catenary electrification systems, and which today depend on trains powered by diesel engines. The hydrogen system designed by Talgo enables conventional network lines to be "electrified" without the need for costly and lengthy adaptation operations, and without the use of fossil fuels.
Green Extremadura
Spain's leading high-speed train manufacturer has selected Extremadura as part of a broader strategy that recognizes the efforts of Extremadura's civil society, business and regional public administrations to innovate and accelerate a transition to completely decarbonized transport networks.
The choice of Extremadura has to do not only with the type of existing infrastructure but also with the fact that it is one of the Spanish regions that have expressed a more decisive commitment to the creation and regeneration of industrial networks based on the local production of hydrogen.
About Talgo
Talgo S.A., is the leading company in the design, manufacture and maintenance of high-speed light trains with industrial presence in seven countries: Spain, Germany, Kazakhstan, Uzbekistan, Russia, Saudi Arabia and the United States. The company is recognized worldwide for its innovative capacity, unique and distinctive technology and reliability. Talgo is the train supplier for the "Haramain" high-speed railway project between Mecca and Medina in Saudi Arabia, and counts the German, American and Russian railway administrations among its customers.
About the SOI H2 Project
The SOI H2 Project is a transversal initiative driven by both the public and private sectors to make the Hydrogen industry a vector of socio-economic development in the Southwest of the Iberian Peninsula. This project has the direct support of LLOABRE, ADRAL and Fundecyt- PCTEX (Junta de Extremadura), which estimates at 50,000 the number of jobs that could be created in the Euroregion ALEX (Alentejo + Extremadura).

Airbus reveals new zero-emission concept aircraft - Innovation - Airbus
All of these concepts rely on hydrogen as a primary power source - an option which Airbus believes holds exceptional promise as a clean aviation fuel and is likely to be a solution for aerospace and many other industries to meet their climate-neutral targets.
"This is a historic moment for the commercial aviation sector as a whole and we intend to play a leading role in the most important transition this industry has ever seen. The concepts we unveil today offer the world a glimpse of our ambition to drive a bold vision for the future of zero-emission flight," said Guillaume Faury, Airbus CEO. "I strongly believe that the use of hydrogen - both in synthetic fuels and as a primary power source for commercial aircraft - has the potential to significantly reduce aviation's climate impact."
The three concepts - all codenamed "ZEROe" - for a first climate neutral zero-emission commercial aircraft include:
A turbofan design (120-200 passengers) with a range of 2,000+ nautical miles, capable of operating transcontinentally and powered by a modified gas-turbine engine running on hydrogen, rather than jet fuel, through combustion. The liquid hydrogen will be stored and distributed via tanks located behind the rear pressure bulkhead.

A turboprop design (up to 100 passengers) using a turboprop engine instead of a turbofan and also powered by hydrogen combustion in modified gas-turbine engines, which would be capable of traveling more than 1,000 nautical miles, making it a perfect option for short- haul trips. | |
A "blended-wing body" design (up to 200 passengers) concept in which the wings merge with the main body of the aircraft with a range similar to that of the turbofan concept. The exceptionally wide fuselage opens up multiple options for hydrogen storage and distribution, and for cabin layout. |
"These concepts will help us explore and mature the design and layout of the world's first climate-neutral, zero-emission commercial aircraft, which we aim to put into service by 2035," said Guillaume Faury. "The transition to hydrogen, as the primary power source for these concept planes, will require decisive action from the entire aviation ecosystem. Together with the support from government and industrial partners we can rise up to this challenge to scale-up renewable energy and hydrogen for the sustainable future of the aviation industry."
In order to tackle these challenges, airports will require significant hydrogen transport and refueling infrastructure to meet the needs of day-to-day operations. Support from governments will be key to meet these ambitious objectives with increased funding for research & technology, digitalisation, and mechanisms that encourage the use of sustainable fuels and the renewal of aircraft fleets to allow airlines to retire older, less environmentally friendly aircraft earlier.
Note to editors: To evaluate and validate these new concept aircraft and assess whether they could be matured into viable future products, Airbus will be focusing its efforts on a number of technological pathways. Grazia Vittadini, Chief Technology Officer, Jean-Brice Dumont, EVP Engineering and Glenn Llewellyn, VP Head of Zero Emission Aircraft, will reveal Airbus' technology roadmap for 2020-2025 at 14:00 CEST, 21 September 2020 during a virtual event on Airbus social media channels.
