Madrid, Spain (Urban Transport News): In a groundbreaking initiative, a consortium comprising 10 Spanish companies is set to revolutionize the transportation sector with the introduction of the Hympulso project. This visionary endeavor aims to design, construct, and implement a cutting-edge hydrogen fuel cell propulsion system onto a high-speed train, marking a significant stride towards sustainable and eco-friendly rail travel. Scheduled to unfold on the renowned Talgo 250 high-speed tilting train, the project holds the promise of electrifying rail networks using energy derived entirely from renewable sources.
The Hympulso project is poised to be a game-changer, introducing a set of innovative technologies that will redefine the dynamics of high-speed rail travel. The focal point of this endeavor is to adapt the Talgo 250 train for a hydrogen-powered future. This adaptation will facilitate the electrification of rail networks, even in areas devoid of overhead power lines, contributing to a cleaner and more sustainable transport infrastructure.
One of the standout features of the Hympulso project is the development of a prototype hybrid bimodal train tailored for passengers. This avant-garde creation will seamlessly transition between catenary supply, when available, and hydrogen-powered batteries in non-electrified sections of the network. The incorporation of fuel cells and batteries, fueled by 100% green hydrogen, showcases the commitment to eco-conscious transportation solutions.
This innovative system utilizes hydrogen batteries to provide energy for the train's electric motors. Powered by renewable sources such as solar photovoltaic or wind, it produces hydrogen, which is stored and then used to power fuel cell-based propulsion systems, as designed by Talgo. The system is complemented by batteries that boost the train's speed during startup, capitalizing on the braking system to recharge. Unlike extended battery systems in the automotive industry, hydrogen (H2) technology emerges as the logical answer for heavy transport, particularly for railway lines without catenary electrification systems. The Talgo-designed hydrogen system allows conventional network lines to be "electrified" without costly and lengthy adaptation operations, eliminating the dependence on fossil fuels.
Led by the visionary team at Talgo, the Hympulso project has garnered support from key partners. Ingeteam is set to play a pivotal role, designing, manufacturing, and testing high-power converters capable of charging batteries from the catenary. Further contributions come from Repsol and Golendus, responsible for developing hydrogen refueling facilities, while Sener conducts an in-depth risk analysis and simulation of services. Optimus3D joins the mission by developing durable materials using additive manufacturing techniques.
The collaboration extends beyond corporate entities, involving educational institutions and regulatory bodies. Comillas Pontifical University and Tecnalia are poised to contribute their expertise to the project, enhancing its academic and research dimensions. Additionally, the inclusion of Adif as an observer adds a regulatory perspective to ensure compliance and safety in the deployment of cutting-edge technologies.
Underscoring the significance of the Hympulso project, it has secured a substantial €6.5 million grant. This funding is part of Spain's broader Strategic Projects for Economic Recovery and Transformation (Pertes), emphasizing the national commitment to fostering innovation and sustainable development within the transportation sector.
As the Hympulso project gains momentum, it stands as a testament to Spain's commitment to ushering in a new era of sustainable high-speed rail travel. By harnessing the power of green hydrogen, this ambitious endeavor not only positions Spain at the forefront of technological innovation but also sets a global benchmark for eco-friendly transportation solutions. The success of the Hympulso project is poised to pave the way for a more sustainable and environmentally conscious future in high-speed rail travel.
