Abstract

Abstract : Water electrolysis is a promising technology for "green" H2 production using electricity generated from renewable energy. Maintaining its energy efficiency, at MW/GW scale and high and variable current density, however, may be a challenge. In this paper, the research gaps related to electrochemical dynamics in the water electrolysis industry are examined. Specifically, the electrode effect can be detrimental to an electrolyser, and this is not yet investigated in water electrolysis processes. By comparing the current research on industrial electrode effects, and the existing thermal thresholds observed in water electrolysis, the importance of detecting electrode effects in water electrolysers is examined.
