Hydrogen Storage

Harnyss' approach utilizes unique solid-state hydrogen that provides a safer and more simple storage mechanism that adapts seamlessly with a variety of applications, including fuel cells.



Our technology stores hydrogen at around 250 psi (+/- 17 bar),compared to traditional methods, which may require 2,500 to 10,000 psi (172 to 690 bar).

Our technology creates high-volume density, which allows us to store 3 to 5 times as much hydrogen as traditional methods using 5,000 - 10,000 psi (345 to 690 bar).

Cost Effective

Harnyss’ technology eliminates the need for compression equipment and the power required to operate that equipment.

Our technology also eliminates the need for extreme heat and/or cryogenics as we are able to adsorb and desorb hydrogen in ambient conditions.

Our formulations do not include any rare earth materials, which reduces cost and availability issues.
