Hydrogen Rail Applications

equipped with fittings from STÖHR ARMATUREN

The industry today
In order to achieve carbon neutrality, greenhouse gas emissions from the rail industry’s diesel–electric engines must be reduced further. Instead of the significant investment required to electrify traditionally powered routes and shunting yards using overhead contact lines, fuel cells can deliver an efficient on-board power supply, providing electric propulsion in cases where batteries are insufficient for energy storage. Hydrogen-fuelled combustion engine technology is also being evaluated for future potential.

Green energy and future needs
Future fuel-cell-powered passenger trains or cargo trains will contribute to a hydrogen ecosystem – an effective way of decarbonising heavy rail traffic and achieving emission-free mobility. And, with the electricity for green hydrogen production coming from renewable sources such as hydropower and solar energy, it is a carbon-free power source.

Our mission
STÖHR is committed to having a positive impact on the environment and offers solutions for hydrogen-based transportation systems at all medium temperatures, valve sizes and pressure levels for both on-track mobile applications and stationary use at filling stations. Get in touch to discuss your design concept and we’ll work with you to design, prototype and manufacture the fittings and installations you need for mass production. We’re open to your challenge!
