Alkaline electrolyser systems still cheapest – OIES
But PEM electrolysers are better suited to producing green hydrogen from renewable generation, study finds
Alkaline electrolyser (AE) systems still offer the largest system size at the lowest cost but are unsuited to some forms of renewable generation, according to a study of the costs of various different electrolyser technologies by the Oxford Institute for Energy Studies (OIES). The paper divides the most promising electrolyser technologies into six major groups: AE; acidic, which includes proton-exchange-membrane (PEM) technologies; solid oxide electrolysers (SOEs); acidic-alkaline amphoteric electrolysers, which include anion-exchange-membrane (AEM) technologies; microbial; and photo-electrochemical. As the paper notes, each technology has its strengths and drawbacks depending on the applica
