Electrical storage for mobile applications is another matter and the main obstacles currently in the way, overcoming weight and cost.
That's why all modern trains have a large deisel engine connected to a generator. Imagine what a battery pack for a train would look like. Only other option would be to have overtrack power lines to feed the trains but then if the power is disrupted the train is stuck dead in its tracks. The next huge advances with electric vehicles will be fuel cell technology coupled with advances in superconductor technology.
Long live hydrocarbons! (technically all hydrocarbons we pump out of the ground is just stored solar energy in chemical form) lol
