FWIW I upvoted you just because the question is reasonable, but I think you're wrong in balance. Last I looked all the current processes for making hydrogen are in fact more environmentally taxing (and worse, CO2 emitting) than the one-time cost of mining lithium.

A LiOn battery is good for many many cycles, and can then be recycled. Hydrogen must be produced and then consumed, and is usually produced from natural gas, itself a greenhouse gas that is on the main a byproduct of the oil industry.

Green hydrogen is the long-term option, which makes hydrogen the much less resource demanding option. People who keep on repeating the 'hydrogen = fossil fuel" argument is just the same kind of argument leveled against battery powered cars such as "coal powered cars."

CO2 emitting but it's point source so straightforward capture and sequestration.
