Ten Spanish companies join forces to apply hydrogen propulsion to a high-speed train for the first time

  • The Hympulso project is part of the Strategic Projects for Economic Recovery and Transformation (PERTES)
  • A new technical car with hydrogen and batteries to be developed for a Talgo 250 train, allowing it to run on clean energy on non-electrified lines.
  • The main partners are Talgo, Golendus, Ingeteam, Repsol, Sener and Optimus3D.

Madrid, 23 January 2024

Ten Spanish companies have joined forces to design, build and install, for the first time in the world, a propulsion system based on renewable hydrogen fuel cells on a high-speed train. Under the Hympulso project, the companies will develop a set of technologies that can be applied to the Talgo 250 'all-terrain' train, making it possible to electrify the rail network with energy generated entirely from renewable sources, even on lines without overhead power lines.

Led by Talgo, Hympulso also includes Golendus, Ingeteam, Optimus3D, Repsol and Sener as partners. Universidad Pontificia Comillas and Tecnalia are collaborators, while Adif is an observer. The initiative has received a grant of €6.5 million and is part of the Incentive Programme for the Innovative Value Chain and Knowledge of Renewable Hydrogen, as part of the Recovery, Transformation and Resilience Plan.

Hympulso will be comprehensive in nature: it will activate the entire renewable hydrogen value chain in the railway system, from production to consumption. The project will also make it possible to analyse the impact of the future transition on the various railway infrastructure assets managed by Adif, such as maintenance facilities or the track.

Thus, the project will result in a joint output of hydrogen supply installations adapted to railways -both mobile and static- and a pioneering prototype of a hybrid bimodal train for passengers with automatic track-gauge change, which will be able to run both on conventional and high-speed networks, using catenary supply when available, or hydrogen and batteries in those corridors that are not electrified.

This holistic perspective is key because tackling the many major technological challenges posed by the adoption of renewable hydrogen in rail transport will require the involvement of multiple stakeholders at all levels, and from both the public and private sectors.

An 'all-terrain' train

All project partners seek to evolve their enabling technologies and expertise in the field of renewable hydrogen with Hympulso. Talgo's objective will thus be to develop, manufacture and test dual-hybrid hydrogen battery traction on a Talgo 250 train, intended for long-distance operations on mixed sections: partially electrified and partially non-electrified.

Called Talgo 250, these trains have two technical end cars each (CET), which are currently used to generate electricity from diesel to power the traction units on sections without catenary. Under the Hympulso project, one of these diesel CETs will be replaced in a Talgo 250 unit by one equipped with fuel cells and batteries to supply electricity to the locomotives using 100% green, renewable hydrogen.

The scope of each partner is as follows:

Ingeteam will design, manufacture and test reversible high-power converters, capable of charging the batteries from the catenary. Repsol and Golendus will be responsible for developing two hydrogen refuelling facilities. Repsol will deploy a mobile facility, while Golendus' hydrogen plant will be a static production and supply facility. For the hydrogen supply facilities and the railway infrastructure, Sener will carry out an overall risk analysis and a simulation of the operation of the services. In both cases, a logistics control platform will be developed to monitor the use of hydrogen in the network.

Finally an SME, the Alava-based Optimus3D will work on more efficient and durable new materials, based on additive manufacturing, and new processes to be used in hydrogen applications.

As for the observer companies, Adif wants to develop its knowledge in the definition of requirements and use cases in the access to the railway infrastructure of hydrogen technology. It will develop the safety requirements associated with the infrastructure and the interfaces with vehicle and refuelling facility, as well as the design of standardised refuelling facilities and collaborate with the use cases on the hydrogen fuelling platform.

Adif will also include the comprehensive management of this new fuels within its wider hydrogen strategy; furthermore, it will contribute during track testing by easing the access to the rail infrastructure.

Initiatives contributing to the transformation of the Spanish economy

The Hympulso project is part of the 'Value chain: design, demonstration and validation of hydrogen-powered mobility' call, which forms part of the PERTE (Strategic Projects for Economic Recovery and Transformation) for renewable energies, renewable hydrogen and storage (ERHA). In the resolution of the call for proposals, this project received the highest score for the soundness of its technical proposal and its innovative nature.

Under the PERTE designation, a sector is identified as a key area for the future of the economy. In total, twelve strategic projects have been approved in areas such as the development of electric and connected vehicles, renewable energies, renewable hydrogen and storage, cutting-edge health, the agri-food sector, the new language economy, the circular economy model, the shipbuilding industry, aerospace, the digitisation of the water cycle, microchips, the social and care economy and the decarbonisation of industry.
