      abstract     = {Green Hydrogen (H2) is generally considered to play a key
                      role in enabling sustainable energy storage, as well as a
                      renewable feedstock to various industrial sectors.
                      Accordingly, the production of H2 by water electrolysis at
                      an industrial scale is a key prerequisite for a
                      transformation of our energy system. With respect to water
                      electrolysis, proton exchange membrane (PEM) electrolysers
                      are generally considered a technology option for the
                      production of green H2 on a large scale. Prior to market
                      ramp-up PEM electrolysers have to undergo substantial
                      de-risking for a technology ramp-up. For a comprehensive
                      de-risking, a fundamental and holistic understanding of the
                      degradation phenomena of electrolysers on an industrially
                      relevant scale is a prerequisite. Field data with different
                      application-specific load profiles needs to be acquired in
                      order to develop countermeasures against possible
                      degradation patterns induced by the operational mode. This
                      is not only crucial for the more mature PEM technology but
                      also in the future relevant for other more novel membrane
                      electrolysis technologies such as anion exchange membrane
                      (AEM) looking to make the step from laboratory operation to
                      large-scale production and deployment. This editorial aims
                      to outline the current status and general workflow of the
                      de-risking process and serve as an introduction to the
                      topics of this special issue ranging from fundamental
                      studies on degradation processes on the catalyst level up to
                      novel factory concepts for ramping up of electrolyser
                      production.},
