Hydrogen Storage

Energy Storage that is Safe, Green, Clean & 100% Renewable

H2G provides the green energy solution that solves the energy storage challenge.  Australia's only commercial Hydrogen storage enabling 100% renewable power systems with no need for back-up fossil fuel.  Our Systems incorporating GKN Technology provide the safest and greenest energy storage solution on the market.


The Game Changer

Solid State Hydrogen Storage using Metal Hydride


The challenge for renewable energy, until now, has been storage.   Stand Alone Power Supplies (SAPs) or disconnected Microgrids have always required back-up power generation, using diesel or needed to maintain a connection to the grid, but now the game has changed.  Our vision of safe storage of large quantities of energy is now a reality by storing Hydrogen as a solid and not a gas or liquid.  Hydrogen is the greenest fuel on the planet and now it is safe and there is twice as much energy stored, when it is a solid, per cubic meter than Liquid Hydrogen!  And fifteen times more than Hydrogen gas at the same pressure.

H2G offers the Australian market a proprietary system that stores hydrogen in a solid state, which means that it's extremely safe and stores at very high density, and with no degradation.  The result is the ability to store large quantities of renewable energy and move wasted green energy from periods of excess to times when its needed.  From Summer to winter, from day to night or from windy periods to times of calm.  The ultimate solution that is safe, lasts for decades and is 100% recyclable.


Solid State Hydrogen storage has already been approved for Utility usage in Australia and has passed bushfire, operation and customer safety regulations allowing Utilities to cut operation costs, reduce fire risk and improve reliability for remote customers.

The Future is Here



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.


No Compression Required

The process flow is ideally matched to electrolysers and fuel cells and does not need an expensive compressor and associated high operating cost


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.

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​)

Low pressure

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

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)


Having solved the renewable energy storage problem H2G now design and deliver solution for Standalone Power Supplies, Micro-grids, Eco Tourism, Remote Communities, Car Depots for night e-car charging, Hydrogen Storage for Chemical Process Plants, Hydrogen Battery Energy Storage Systems; the opportunities for environmentally sustainable energy and to eliminate the need for diesel and connection to the grid are endless....

Zero Emission Communities


H2G possess the technology to create zero emission communities anywhere in our vast country, or on our islands.  This brings silent power and therefore prosperity to regional and disadvantaged communities. Australia's abundance in natural renewable energy makes this market particularly exciting.
