Stack Assembly Technician

Hysata is an Australian green hydrogen technology company headquartered in Wollongong, New South Wales, that designs and manufactures high-efficiency electrolysers for the production of green hydrogen. The company's core mission is to accelerate the decarbonisation of hard-to-abate sectors by making green hydrogen economically competitive through a step-change improvement in electrolyser efficiency and system design. Hysata's electrolysers achieve a world-leading 95% system efficiency, equivalent to 41.5 kWh per kilogram of hydrogen, which surpasses the International Renewable Energy Agency's 2050 efficiency target and has been validated through publication in the peer-reviewed journal Nature Communications. Hysata's technology is distinguished by a drastically simplified balance of plant, modular architecture, and a design philosophy optimised for mass manufacturing, all of which contribute to delivering the lowest Levelised Cost of Hydrogen (LCOH) for customers. The company offers a turn-key electrolyser solution intended to transform the economics of green hydrogen production globally. Backed by leading strategic and financial investors, Hysata is scaling rapidly toward multi-gigawatt manufacturing capacity. The company has secured notable partnerships and commercial agreements, including deals with ACWA Power and POSCO Holdings, and has received support through Australia's Hydrogen Headstart funding programme. Hysata has also been recognised for its workplace culture, winning a Best Startup Culture award in 2024, and continues to engage with policymakers and international stakeholders to advance the green hydrogen industry.
