when battery technology increases, there will be no need for something like Hydrogen storage. The future is batteries and electric motors.
Battery swapping might come into play in the meantime, before you can charge a 500 km battery in a couple of minutes.
As the the link in the OP, I don't see any reason why car fleets couldn't average 40+ MPG today. 55 MPG in 15 years should be a bare minimum standard. It should be 75-80 MPG.
Personally, I'm not going to be in the car market for a couple of years, but I'm really hoping I never have to buy an gas burning car again. I'd love to be able to buy only electrics from now on.
Fun fact, the elctric car is older than the gasoline powered car. Imagine if all of the R&D money that has gone into gas powered cars in the last 100 years had gone into electric cars?
Battery swapping totally eliminates the fear of the large cost of buying a new battery all at once.
