Storage, transport, and fueling are all big problems for personal vehicles. It may still be useful for energy storage and industrial processes (see sibling comments). Better storage for excess solar/wind generation would be very helpful. Perhaps it would also be useful for limited range applications where you wouldn’t need lots of spread out stations like for vehicles at a port that do a lot of work but never get very far from home.
