Meet the company producing the lowest cost green hydrogen available to date - Hysata

Hysata is an Australian electrolyser manufacturer building the world’s most efficient electrolyser

Hysata is an Australian electrolyser manufacturing company that has developed a unique patented ‘CapillaryFed Electrolysis’ cell coupled with a simplified Balance of Plant (BOP).

Founded in a lab at the University of Wollongong, Hysata’s technology was founded by a team of PhD students led by Dr Gerry Swiegers, an industry veteran with over 30 years’ experience in hydrogen and regarded as a global electrolysis expert. His passion for transformative technology was shared by Hysata CEO Paul Barrett, another industry veteran with a PhD in chemical engineering and a strong understanding of electrolyser technology development.

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

• World’s highest efficiency due to record cell efficiency and simple overall design

• Simplified balance of plant (BOP) enabled by high efficiency

• Ease of manufacturing and scaling due to simple unit operations and modular technology

Our vision is to enable a clean energy future. Green hydrogen is a critical decarbonisation vector for hard-to-abate sectors such as steelmaking, chemical manufacturing and heavy transport. Today's high capital and operating costs of commercial electrolysers make green hydrogen less competitive with incumbent technologies. Hysata's breakthrough efficiency improvement will deliver the lowest cost green hydrogen so far.

High costs hinder green hydrogen production, mostly driven by electricity costs. Hysata's electrolysers with exceptional efficiency will transform the economics of green hydrogen production. Hysata's founding team has 50+ years’ experience across electrolysers and high-volume manufacturing. Backed by leading global investors, Hysata is moving rapidly towards multi-gigawatt scale production to combat climate change.

Our success and growth have been supported by an AU$42 million Series A round, as well as AU$20 million in government grants, further demonstrating our innovation’s market impact.

We have now built a state-of-the-art 8000m2 manufacturing facility in Port Kembla, NSW, which gives us room to grow to full scale manufacturing. Starting with development of 100 MW production line from 2024, we will rapidly scale to multi-GW scale manufacturing – ultimately employing thousands of skilled staff across the globe.

As testament to the value of Hysata’s innovation, we have secured 9.4 GW of conditional orders and Letters of Intent set for delivery from 2026; with a further 30 GW in our pipeline.

Hysata will be delivering our first commercial scale 5 MW electrolyser in 2025, supported by the Australian Renewable Energy Agency and Stanwell Corporation. Through this partnership, Hysata’s electrolyser will be manufactured at our new facility and installed adjacent to the Stanwell Power Station near Rockhampton, Queensland.

Hysata was the winner of the Banksia Foundation's 2024 SME Sustainable Leadership Award.
