An Australian start-up says it has invented a new super-efficient type of electrolyser that uses plasma, the fourth state of matter, to reduce the cost of green hydrogen by a factor of three.
Melbourne-based Hydrogen Systems Australia (HSA) says that today’s PEM (proton exchange membrane) electrolysers produce hydrogen at a levelised cost of about $5-7 per kilogram, while its new plasma electrolysers would produce H2 for $2/kg by 2024 (based on a power price of $35/MWh when operating for 12 hours a day) — and could go even lower after that.
