Toyota’s hydrogen-electric development is very interesting.

Yes, hydrogen has its own issues (cost of collecting and storing hydrogen, leaking). Honda already has product. Perhaps Japan, an island nation sees possibilities of collection of hydrogen from the ocean.

At least you don't have to do so much digging to get it compared to lithium and cobalt.

There are quite a few ways to produce hydrogen. I'm interested to see what is found from the various development efforts. I wonder what the replacement (maintenance) costs for materials might be for a hydrogen car as compared to one that uses lithium.
