Elon Musk has called hydrogen fuel cell cars 'mind bogglingly stupid'

Elon Musk is no fan of hydrogen fuel cell vehicles, calling them mind bogglingly stupid.

A hydrogen powered car stores gaseous hydrogen in a high pressure tank.

That hydrogen is then released into a fuel cell when the car is switched on, where the energy stored in hydrogen is converted into electricity.

There is no combustion involved in a hydrogen powered vehicle, at least not if everything works properly.

The efficiency of hydrogen power in a vehicle is somewhere between 38 and 22% .

This is better than an internal combustion engine, which has an efficiency as low as 13% .

But these fuels both pale in comparison to the efficiency of a battery electric vehicle, which achieves an efficiency of between 73 and 80% ..

For mass produced personal vehicles, batteries are most likely going to be the best option.

Hydrogen is very useful for heavy duty and commercial vehicles because you can store more energy in a hydrogen tank than in a battery and you get that fast refill.

There's no sense in tearing out gas stations just to replace them with hydrogen stations or replacing gasoline tanker trucks with hydrogen tankers.
