>Hydrogen doesn't have that problem and in the end accounting for lithium mining destroying the environment I still don't think it's that clear cut.

99% of the hydrogen currently produced come from natural gas. Of course, it could be made from water but lithium can also be extracted cleanly from clay with with table salt.

Besides, making hydrogen from water uses over 3 times the energy required to make and charging a battery (the well-to-wheel efficiency of hydrogen vehicles is that low).

So for now and the foreseeable future, hydrogen is far worst for the environment than Li-Ion batteries.

Moreover, room-temperature fuel cells require platinum-group metal catalysts and this is the main reason that has prevented the introduction of vehicles with fuel cells.

High-temperature fuel cells do not need expensive catalysts, but it seems that nobody succeeded to reach acceptable lifetimes for them.

On the other hand, if the fuel cells contain expensive materials then we're more likely to actually recycle them.
