Electrolyzer Sizing and Techno‐Economic Assessment of Small‐Hydropower‐Based Green Hydrogen Using 3 Years of Hourly Generation Data

Energy Science &Engineering, EarlyView.
Three years (26,280 h) of measured Miryang Dam hydropower data were used to screen 300–1200 kW PEM electrolyzer capacities. A 600 kW unit provided the equal‐weight technical balance between hydropower capture (84.71%) and electrolyzer utilization (86.25%), whereas the planned 1 MW design captured 98.11% of available renewable energy but operated at a ...
