I'm thinking of all batteries. We need breakthroughs in cost, because it isn't economically justifiable right now to store renewable energy in batteries. We just fire up the existing power plants and crank out the shortfall in electricity.

EVs have essentially a $10,000 fuel tank, which is smaller "capacity" than regular $100 fuel tanks, which takes hours to fill, which degrade over time, which require thermal management, which weigh a lot...

Huge hurdles to overcome. We'll get there eventually.
