Few years ago NIST did a study on hydrogen vehicle charging stations, and they found out that the best design was to place electrolysers locally instead of transporting it. Such a station could effectively double as BEV charging station, as it's main requirements would be beefy grid connection plus water source, with tanks being used only to buffer hydrogen.
