Hyrex is an innovative Norwegian hydrogen technology company started by a group of highly experienced engineers and industrialists. Our vision is to offer zero-emission powerpacks for pleasure boats and utility vessels where weight and size of a sufficiently large battery packs is not economically or physically feasible. Our initial target market, the day cruiser, is ripe for innovation. By combining an elecric motor with batteries and a hydrogen fuel cell range extender we have been able to reduce weight by 70% and cost by 80% compared to an equivalent battery-only system. Our system has a filling time of a few minutes and makes it possible to travel for 25 hours in unrivalled comfort without re-filling. The modular setup of Hyrex Boost allows us to scale hydrogen tanks and battery capacity to different sizes of boats and vessels.
