Technology

Electrolysers use electricity to split water into hydrogen and oxygen and are the key technology for producing green hydrogen.

Green hydrogen is widely acknowledged to be a crucial part of reaching net zero emissions globally, enabling decarbonisation of hard-to-abate sectors like steel, heavy transport and chemicals.

It is expected to supply 15-25% of energy in a net zero global economy, creating a huge commercial and decarbonisation opportunity.

The main challenge today for the green hydrogen industry is that existing electrolysers are complex, costly and only moderately efficient.

Over the last 50 years, there have only been incremental improvements in electrolyser designs.

Until now.

Hysata has completely redesigned the electrolyser, resulting in a step-change improvement over existing designs, redefining efficiency, balance of plant simplicity and modular manufacturability.

Hysata’s technology offers step-change improvements in 3 key areas:

New category of electrolysis with world’s highest efficiency

95% system efficiency (41.5 kWh/kg), compared with ~75% for incumbents (52.5 kWh/kg)
Low-cost design, based on earth-abundant materials

Simplified balance of plant (BOP)

High cell efficiency eliminates the need for expensive cooling
Efficient, low-cost, grid-friendly power electronics
Integrated BOP and stack design to provide an optimised, turnkey system that delivers high purity green hydrogen at the lowest levelised cost

Ease of manufacturing and scaling

Manufacturing is based on simple unit operations; easy to automate and scale
Modular technology – same basic building block for MWs to tens of GW installations
