Membrane-free water electrolysis26 Aug 2021 18:37
Does anyone have any information on membrane-free water electrolysis? Clean Power Hydrogen, manufacture them and have won an order from Octopus Hydrogen, for the supply of a 1MW electrolyser. They claim it is a less expensive and more robust technology than PEM. Their web site does not give much information, but they claim it allows green hydrogen to be produced efficiently using intermittent renewable electricity with no rapid drop off in performance that is associated with membrane technologies. It also uses a lower grade of purified water, there has to be some disadvantages surely or it could be a serious threat.
