Our future is Green Safe Clean Hydrogen

Our energy demand is growing and clean energy from renewable sources is THE cornerstone for future living. Cutting-edge storage solutions are key to the success of the energy transition.


This is where GKN Hydrogen comes in.

Metal Hydride Energy Storage


All-in-one solution for zero-emission power supply.


Solid-state hydrogen storage provides safety through design.


15x smaller size than 40bar hydrogen gas tanks.

A modular system for maximum flexibility

Our state-of-the-art metal hydride storage has been developed and refined over the last 8+ years to become the most reliable and secure hydrogen storage solution on the market. 

The robust system generates green hydrogen from fluctuating renewable energy sources, storing it compactly and safely in metal hydride over long periods of time.

We store green hydrogen from renewable sources for various applications

100% recyclable

The standard metals we are using are 100% recyclable. Our system generates no wastes during operation. The only side product from the process is pure water.

Low pressure

The low-temperature metal hydride storage system operates at the same pressure level as electrolysis and fuel cells.

15 years + lifetime

Our systems save about 150 tons CO₂ over its life-time.

(Estimated 4x storage turnover / year for a 120kg H2 sized HY2MEDI system​)

No Capacity Loss

The metal hydrides can last for decades without any losses. (99% capacity after 3,500 cycles vs. 70% after 2000 cycles with Li batteries)

HY2 Energy Systems

Our modular systems bring safe, green energy to residential housing, industrial and transportation sectors. Whether in Micro-Grids, for emergency back-up power systems or energy conversion plants. The possibilities are infinite.
