About the Hydrogen Sauna Boat

Hydrogen is expected to play an important role as a low-emission energy source in the marine sector. However, practical experience with hydrogen applications in everyday environments remains limited, particularly in locations where fixed refuelling infrastructure is unavailable. 

Cefmof has launched the Hydrogen Sauna Boat project to develop and test the use of hydrogen in a recreational watercraft environment and to raise awareness of hydrogen’s potential as part of future energy systems.

The Hydrogen Sauna Boat utilizes swappable hydrogen cartridges, enabling hydrogen use without harbor-based refuelling infrastructure. Hydrogen is used both for electricity generation through a fuel cell system and as a direct energy source for sauna heating and grilling. 

Objectives

The Hydrogen Sauna Boat enables Cefmof and its project partners with an opportunity to develop, test, and evaluate new hydrogen solutions in a real operating environment. The project also helps to build expertise in hydrogen use and identify new application areas. 

Another objective is to improve understanding of how hydrogen can be used in environments without fixed hydrogen infrastructure. The project will provide practical experience that can help applications and support the growth of the hydrogen economy in Finland.
