The economics of green hydrogen have always come down to one problem: electricity is the dominant input cost, and existing electrolysers waste too much of it.
Hysata's fundamentally different approach uses a capillary-fed electrolysis cell underpinned by two key innovations: an ultra-low resistance separator and bubble-free operation — eliminating the primary sources of energy loss in conventional designs and achieving 95% system efficiency, a step change that already exceeds IRENA's efficiency target for 2050.
The commercial implications are significant.
The increased efficiency produces 580kg of green hydrogen per day per MW of electrolyser capacity, compared to around 470kg for incumbent systems, and could save green hydrogen producers an estimated US$3 billion in renewables capex for a typical one million tonne per annum project.
The design also simplifies manufacturing — generating far less waste heat, requiring twenty times less liquid per megawatt than a conventional alkaline electrolyser, and lending itself to modular, scalable production.
Founders
czero
USA
CZero produces clean hydrogen by thermally decomposing natural gas into hydrogen and solid carbon — a turquoise hydrogen pathway that avoids CO₂ emissions and produces a sequestrable solid byproduct.
Endua
Australia
Endua makes modular 150kW hydrogen fuel cell systems for off-grid and remote power — providing clean, dispatchable backup power without diesel.
Hydgene
Australia
HydGene Renewables has engineered bacteria that convert sugars from waste biomass — agricultural residues, grain stubble — into green hydrogen via biological fermentation, enabling decentralised, carbon-negative hydrogen production in rural and remote areas.
