Electrolyser costs to fall sharply – Csiro

Alkaline electrolyser and proton-exchange membrane unit deployment costs will fall to less than a quarter of current levels by 2050 as technologies develop, research body says

Alkaline electrolyser (AE) deployment costs will fall to less than a quarter of their current levels by 2050, with proton-exchange membranes (PEM) costs also declining to reach parity with the more established technology by 2040, according to a report by the Commonwealth Scientific and Industrial Research Organisation (Csiro), which is funded by the Australian government. PEM electrolyser costs are likely to fall more rapidly than costs for AE units as the technology is less developed and has offers further efficiency improvements. Under a scenario based on current international policies, AE costs will fall from $1,378/kW currently to $296/KW by 2050, with PEM costs falling from $2,456/kW cu
