Job Description

About us

n

Hysata is on a mission to accelerate the shift from fossil fuels to green hydrogen with the world's most efficient electrolyser. Our breakthrough capillary-fed electrolyser achieves an unprecedented 95% system efficiency (41.5 kWh/kg) – a step change from incumbent technologies, which typically sit at ~75% and already ahead of International Renewable Energy Agency's 2050 target. This leap in performance enables a radically simpler system design, slashing both energy use (opex) and system and renewables capex.

n

Hysata's innovation has captured global attention, including publication in Nature Communications and support from leading strategic and financial investors such as BP, POSCO and Vestas. With over 100 team members, we're a high-performing, purpose-driven company, proud to be 35% women, representing 20+ nationalities, and united by a shared mission to enable the decarbonisation of hard-to-abate sectors such as steel, chemical manufacturing, shipping and aviation.

n

Having secured Australia's largest ever cleantech Series B raise of US$111 million, Hysata is scaling rapidly to bring our technology to market. With strong customer demand and a clear path to manufacturing at scale, we are on track to become a global leader in green hydrogen and put a major dent in global emissions.
