Sorry AF AF, but hydrogen powered vehicles & batteries are a FURPHY!
Ask the Hindenburg, NASA & Space Shuttle designers & crews."Even small amounts of liquid hydrogen can be explosive when combined with air, and only a small amount of energy is required to ignite it. Both its explosiveness and the extremely low temperatures involved make handling it safely a challenge"
They are currently only used for mass high power rocket launches & very dangerous at that due to high combustibility, massive expense/weight.
They must be kept in freezing liquid form to reduce size & convert to gas, think of a massive frozen barbeque canister on steroids.
Liquid hydrogen tanks require massive pressure, minus 230 degrees celsius, are heavier than diesel in liquid form & have more volume more than LNG & are highly combustible producing an explosive reaction with air (unlike cf liquid nitrogen) & a lot more expensive to produce & store than fossil fuel or even liquid nitrogen.
see wikipedia here-
"Although liquid hydrogen gives a high Isp, its low density is a disadvantage: hydrogen occupies about 7x more volume per kilogram than dense fuels such as kerosene. The fuel tankage, plumbing, and pump must be correspondingly larger. This increases the vehicle's dry mass, reducing performance. Liquid hydrogen is also relatively expensive to produce and store, and causes difficulties with design, manufacture, and operation of the vehicle. However, liquid hydrogen is extremely well suited to upper stage use where Isp is at a premium and thrust to weight ratios are less relevant"

The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and ... of the Shuttle flights, and was last used on the ill-fated Space Shuttle Columbia disaster (STS-107).
A catalytic converter is needed to convert H from air but can be done but very slow, slower than EV recharging..
The converter requires filters and platinum/nickel/heavy metals to incite a chemical reaction to refine the H component in air.
The space shuttles and current space rockets have these and they are very explosive and dangerous alright.
If they explode in site they will kill all inside and other vehicles nearby also. The Space Shuttle & Hindenburg disasters were caused by this hydrogen explosion not the break up of the shuttle or the pressure itself but by fire & explosive pressure.
Thats why its called a hydrogen bomb, the power is many multiples of its pressure and mass.In addition to the famous Hindenburg disaster, dozens of hydrogen airships were destroyed by fire, and no American airship has been inflated with hydrogen ...
All I can say is its hypocritical.
Someone like MD sold him a unicorn full of hot air so they can get his POS shares cheap. Covid side effects maybe. Its nuts.
Any takers on going for a shop run on the hindenburg or space shuttle with a live bomb on board?
And they say Tesla batteries are dangerous, this would be 100 times more so.
Nickel is the future! The more nickel the more safer & longer lasting the battery.
