    Not at all. Hydrogen electrolysis efficiency is about 70-80%. When turning it back into electricity, fuel cells are 40-60% efficient. That means your electricity costs are about double for the complete round trip.

    Conversely, lithium batteries (and most other types) are over 90% efficient and directly give you electrons.
