Hydrogen Maritime Applications

equipped with fittings from STÖHR ARMATUREN

The industry today
For many years, the maritime sector treated hydrogen only as an option for the future under ‘further running’. Today an increasing number of projects involve hydrogen use, as shipping companies look for solutions to address the growing pressure to say goodbye to fossil fuels.
Although major players in the maritime industry know large tankers and cruise ships won’t run on hydrogen or similar fuels tomorrow, the discussion about alternative fuels has reached a new dimension. Though many shipping companies are increasingly reliant on liquefied natural gas (LNG), the industry is aware of the transitional, temporary nature of the technology.
Of course, there’s a lot more to the maritime industry than just tankers and sea cruisers. While underwater hulls have used fuel cells for more than 20 years, other sectors – such as yachting, passenger and car ferries, river freight transport, river cruisers and leisure shipping – represent a vast opportunity for innovation.


Green energy and future needs
Achieving the goal of climate neutrality demands a new energy ecosystem for the shipping industry – and this, in turn, requires significant investment, collaboration and technology development. Green hydrogen, methanol and ammonium will play a major role in the industry’s road to zero.
Beside the many different challenges raised by boats that operate under vastly different conditions and at various sizes, effective solutions are required for the control process between on-ground fuel tanks, dockside filling stations, onboard fuel infrastructure and the point of use.

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-water mobile applications and stationary use at dockside 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!
