Hydrogen Aviation Applications

equipped with fittings from STÖHR ARMATUREN

The industry today
The aviation industry has its sights set on climate neutrality from 2050. To achieve this ambitious goal, it must move away from its focus on kerosene – the aviation industry’s go-to fuel for decades – and make room for a variety of new energy pathways capable of powering future aircraft.

Green energy and future needs
Achieving this will require a new energy ecosystem for aviation – which, in turn, will require significant investment, collaboration and technology development. Green hydrogen will play an integral role in the aviation industry’s road to zero.
Besides many different issues that drive future solutions for aeroplanes, helicopters, urban air mobility vehicles (UAM) and other unmanned flying platforms, the challenge of climate neutrality demands suitable solutions to manage the control process between the gas tank and the point of use in challenging environmental conditions.

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 in-air mobile applications and stationary use at airport 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!
