Hysata believes it has developed an electrolyser more efficient than any other on the market. Now it's taking its technology to the next level and scaling up to 5MW. To put that in context, Australia's largest operational electrolyser at present is the 1.25MW unit at Hydrogen Park South Australia (HyP SA). If successful, Hysata hope to produce 20 x 5MW electrolysers per year, or roughly 100 megawatts worth of generation capacity.
