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!

Almost all (95%) of our current hydrogen production is through a process called steam reforming of natural gas. So we extract methane from the ground, probably using fracking, then we use lots of energy to break the methane apart at special plants. We capture the hydrogen for later use. Unfortunately, hydrogen is a major PITA to store and transport. Ultimately, we likely move the hydrogen to the refuelling station in very strong high pressure tanks mounted on transport trucks which are probably burning diesel. Since hydrogen is so difficult to store and transport efficiently, we cannot deliver significant quantities at a single time. Same issue for the vehicle that uses it. It must be stored under extremely high pressures in special tanks.
But, then if you purchase a hydrogen vehicle and are lucky enough to live somewhere near a very rare hydrogen station you can claim you are a climate conscious green consumer doing your part to prevent climate change. /S
