Hydrogen Storage

Wind (onshore, offshore, floating), solar (rooftop, ground-mounted), hydroelectric, green PPA

PEM (polymer electrolyte membrane) and developing technologies such as AEM (Anion Exchange Membrane), membrane free, and graphene-based membranes

The Hydrogen Promise

Using green hydrogen as energy will help lead the world towards decarbonisation.

Energy Vector

Hydrogen screens attractively as fuel, with >2.5x the energy content per unit mass of gasoline and >2x that of natural gas making it attractive for long haul transport Compressed hydrogen fuel cell systems having c. 70% lower weight per unit of output energy compared to batteries and >30% lower volume per unit of output energy

Hydrogen is the most appropriate technology for seasonal mass storage. In contrast to batteries, it doesn’t run down with the passage of time. Hydrogen is most frequently stored in tanks at medium or high pressure

Hydrogen can absorb the surplus energy produced by renewable sources and be reused for operations like regulating the network or be transported to provide mobility. The conversion of hydrogen into electricity via a fuel cell only produces steam and heat. No greenhouse gases are involved and there are no toxic fumes.
