Under the pressure of climate change, the demands for alternative green hydrogen (H ₂ ) production methods have been on the rise to conform to the global trend of transition to a H ₂ society. This article proposes a multirenewable-to-hydrogen production method to enhance the green H ₂ production efficiency for renewable-dominated hydrogen fueling stations (HFSs). In this method, the aqueous electrolysis of native biomass can be powered by wind and solar generations based on electrochemical effects, and both electrolysis current and temperature are taken into account for facilitating on-site H ₂ production and reducing the electricity consumption. Moreover, a capsule network based H ₂ demand forecasting model is formulated to estimate the gas load for HFS by extracting the underlying spatial features and temporal dependencies of traffic flows in the transportation network. Furthermore, a hierarchical …
