Eli5, how do hydrogen cars work?

Question

Hi guys! Saw this article on BMW saying, hydrogen is the next best thing – from electric cars.

Can anyone ova here, explain in a nutshell how hydrogen cars work? How it’s stored? How it’s made / refined heard its (h2o something)?

The safety of it, in case of an accident?

The transportation of the liquid?

Also, can hydrogen cars accelerate as quick as the Tesla’s? 😯

Thanks!

Hydrogen power is basically gas power but with extra steps since the hydrogen is obtained from fossil fuel refineries. Getting hydrogen from water is not economically viable and is very energy intensive compared to getting it from fossil fuels.
