CSIRO electrolyser pilot demonstrates efficiency and durability at Bluescope Steel Plant

CSIRO, Australia’s national science agency, has successfully trialled its game-changing hydrogen production technology at BlueScope’s Port Kembla Steelworks in New South Wales, demonstrating affordable and renewable hydrogen can be generated at scale to help decarbonise heavy industry.  

CSIRO’s tubular solid oxide electrolysis (SOE) technology has clocked 1000 hours of successful operation in the trial with BlueScope Steel which commenced in October 2024.  

Unlike conventional hydrogen electrolysers, which rely heavily on electricity to split water into hydrogen and oxygen, CSIRO’s advanced SOE technology uses both waste heat (for example, steam from the steelworks) and electricity to produce hydrogen with greater efficiency.  

Dr Sarb Giddey, Senior Principal Research Scientist and Group Leader in CSIRO, said the trial produced hydrogen with an electrical input of less than 36kWh per kilogram of hydrogen, by using the steam produced in the plant by the steelmaking processes. 

Dr Giddey said,  

Since electricity takes up the lion’s share of variable production costs for renewable hydrogen, a substantial reduction in the electricity required (up to 30 per cent saving) for hydrogen production could be a game changer for the nascent hydrogen industry,

“Taking a new technology out of the lab and into the field can highlight unforeseen challenges, so we are delighted to see that our technology is meeting the performance requirements in terms of hydrogen production, electrical efficiency and reliability.”  

Chris Page, Head of Future Technologies at BlueScope, sees hydrogen as an important part of BlueScope’s pathway to net zero.

Mr Page said,  

BlueScope is proud to support pilot projects on site, which align with our goals of low carbon emission steelmaking in the future.

“The CSIRO electrolyser pilot has produced positive outcomes in its short-term operation, and we look forward to seeing it evolve,”

CSIRO spinout Hadean Energy has licensed CSIRO’s SOE technology and is on a mission to accelerate industrial decarbonisation.  

Chris Rowland, CEO of Hadean Energy, said the tubular SOE technology has a further advantage of being inherently less expensive to build because of the simplified manufacturing process and more readily available materials. 

Mr Rowland said,

The 1000-hour milestone validates the technology in a real-world industrial setting, increasing the technology readiness level to prepare for commercialisation,

“It shows the potential for Hadean Energy’s electrolyser to decarbonise hard to abate industries.”  

This research is supported by the Science and Industry Endowment Fund. 

While CSIRO is trialling the tubular SOE electrolyser in the field with Bluescope, Hadean Energy is testing the long term durability and performance of the modular design at CSIRO’s Hydrogen Technology Demonstration Facility. Following these successful trials, Hadean Energy is preparing to showcase a 5kW demonstration unit as part of the Australia-UK Renewable Hydrogen Innovation Partnerships. This will serve as a stepping stone toward a large-scale industrial pilot, positioning Hadean Energy as a leading global clean hydrogen technology provider.
