Energy Storage is a dead end technology.Electric motors are pretty awesome. No torque reduction over the million mile life of the motor.
Electrical energy storage (batteries) is decades away from free market viability.
Electrical energy transfer safety and battery tech is pretty dicey to enable really fast MW charging to be equivalent to gasoline refueling time.
I think Porsche's synthgas and potential synthgas blends have real free market potential.
You will never be able to "Store" the same amount of energy as a tank of gasoline/diesel/H2 and refuel it in a way that itns time consuming without destroying the battery.
Its a blackhole.
