A recent study conducted by Danish scientists and engineers from Topsoe, a Danish electrolyzer manufacturer, has demonstrated that solid-oxide electrolyzer cell (SOEC) stacks can effectively operate with intermittent and variable wind power without experiencing additional degradation. This is a great plus for this particular technology, but durability and Capex concerns still outweigh the benefits. The study, published in the journal Applied Energy, involved testing a 7kW SOEC stack with a power supply resembling the profile of an onshore wind farm in Denmark. Over a period of 88 days, the stack was operated for 2,104 hours, with approximately 70% of the time using a fluctuating power supply. The main findings revealed that the fluctuating power supply had no discernible impact on…
