However, renewable hydrogen is not cost-competitive with fossil fuels, due to the moderate energy efficiency and high capital costs of traditional water electrolysers. Here a unique concept of water electrolysis is introduced, wherein water is supplied to hydrogen- and oxygen-evolving electrodes via capillary-induced transport along a porous inter-electrode separator, leading to inherently bubble-free operation at the electrodes. An alkaline capillary-fed electrolysis cell of this type demonstrates water electrolysis performance exceeding commercial electrolysis cells, with a cell voltage at 0.5 A cm<sup>-2<\/sup> and 85 \u00b0C of only 1.51 V, equating to 98% energy efficiency, with an energy consumption of 40.4 kWh\/kg hydrogen (vs. ~47.5 kWh\/kg in commercial electrolysis cells). High energy efficiency, combined with the promise of a simplified balance-of-plant, brings cost-competitive renewable hydrogen closer to reality.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1038\/s41467-022-28953-x Authors: Aaron Hodges, Anh Linh Hoang, George Tsekouras, Klaudia Wagner, Chong Lee, Gerhard F.
