Wollongong-based hydrogen startup Hysata has been granted $20.9 million from ARENA to demonstrate their next generation hydrogen electrolyser technology at commercial scale.

Hysata will develop and test a 5MW unit at their new manufacturing facility in Port Kembla. The electrolyser array will then be installed in-situ for further testing and validation before it is relocated to Queensland.

Queensland government-owned power company Stanwell Corporation is backing the project with $3 million, as well as providing the site and facilities for the field deployment of the electrolyser.

The demonstration unit will be installed adjacent to the Stanwell Power Station near Rockhampton, Queensland. The site has available land, water and grid connection capacity.

Spun out of ARENA-funded research at the University of Wollongong, Hysata was established to commercialise this pioneering electrolysis technology.

Hysata’s proprietary ‘capillary fed’ electrolyser cell eliminates almost all resistance in the electrolysis process. Existing electrolysers face energy losses from electrical resistance and gaseous bubbles forming on electrodes, reducing the overall efficiency of the system.

Hysata’s technology has been proven to produce hydrogen with 95% (41.5kWh/kg) efficiency, well ahead of incumbent technologies that operate with efficiencies close to 75% (52.5 kWh/kg).

This has the potential to reduce the cost of renewable hydrogen production through reduced electricity inputs. The technology also offers lower balance of plant costs, with reduced electrical resistance resulting reduced cooling requirements.

If delivered at scale, these reduced input costs will help lower the levelised cost of hydrogen, making renewable hydrogen a commercially viable energy resource.

ARENA has previously awarded Hysata $8.98 million under the German-Australian HyGATE program, with an additional contribution from the German Government’s Federal Ministry of Education and Research (BMBF) of €5.9 million.

With the help of the HyGATE grant, Hysata is currently working on the development of a 200kW electrolyser system that will demonstrate the key components of the 5MW commercial scale demonstration unit.

Hysata CEO Paul Barrett said this was a significant milestone in Hysata’s plans to rapidly scale its groundbreaking technology needed to accelerate the world’s transition to net zero emissions.

“Hysata is proud to be partnering with ARENA and Stanwell to enter our next phase of commercialisation.

“Green hydrogen is critical for decarbonisation of hard-to-abate sectors, and we are committed to helping our customers deliver the world’s lowest cost green hydrogen.

“With exceptional 95% (41.5 kWh/kg) efficiency combined with cost-effective materials and reduced engineering, procurement and construction (EPC) costs, Hysata’s electrolyser will transform the economics of green hydrogen production.

“We look forward to creating more local jobs and strengthening Australia’s sovereign manufacturing capabilities through this project, which will pave the way for Hysata’s scaling to fulfil a multi-billion-dollar pipeline of orders from around the world.”
