Hadean Energy targets hydrogen using less electricity for heavy industry

Australia’s national science agency CSIRO and corporate advisor RFC Ambrian have co-founded Hadean Energy, which aims to produce hydrogen with 30% less electricity to decarbonise heavy industry.

CSIRO will trial the technology at BlueScope’s Port Kembla Steelworks, starting in April 2024, to demonstrate the equipment at pilot scale in an industrial environment.

Its tubular solid oxide electrolysis (SOE) technology efficiently produces hydrogen by electrolysing water using a combination of heat and electricity and promises to significantly reduce hydrogen production costs and industry emissions through process efficiencies.

SOE operates at temperatures close to 800oC, so part of the energy cost is heating up water. But heavy industry often has waste heat or low-cost heat as part of their processes, which can be used to pre-heat the water going into an SOE electrolyser.
