rocketjoe79 saysHydrogen
BOOM!
Ever used gasoline? It is far more dangerous. H2 can be used as a feed stock to make synthetic fossil fuels. The Germans did it in WW2 when they were cut off from their oil supplies. With "cheap" oil being more and more difficult to sell, synthetic gasoline may make economic sense. The alternative is to use sand tar
Electric vehicles with fusion or fission powered reactors make the most sense for long term sustainability.

H2 is substantially more dangerous than gasoline wrt to combustion.
Hydrogen possesses the NFPA 704's highest rating of 4 on the flammability scale because it is flammable when mixed even in small amounts with ordinary air; ignition can occur at a volumetric ratio of hydrogen to air as low as 4% due to the oxygen in the air and the simplicity and chemical properties of the reaction. The storage and use of hydrogen poses unique challenges due to its ease of leaking as a gaseous fuel, low-energy ignition, wide range of combustible fuel-air mixtures, buoyancy...

Have you ever worked with H2 or trained to be a fire fighter for an industrial facility? I have and maintain that gasoline is far more dangerous. H2 has a LEL of 4% and this is bad but a H2 fire can be managed a lot more easily than gasoline. H2 also tends to dissipate a lot easier. Gasoline not so much. Gasoline is nasty stuff because it sticks around and is a lot more difficult to fight.

Millions of cars on roads will be very different from a well-managed and centralized industrial facility.
Will read the link - thanks.
Seems kinda counter-intuitive that something which is more flammable and kept under very high pressure than gasoline would be less problematic. We have to be quite careful in lab with H2. A few times back in day I managed to set stuff on fire while working with H2 (ignited because of presence of precious metal catalysts), running reactions under high pressures of H2 (lower than ones needed in tanks) required special, explosion-protected rooms, while flammable solvents never caused much problems on our relatively small (up to tens of liters) volume.
Hydrogen is the most reactive element in all reality. Keeping it separate from combining chemically requires super duper infrastructure and of course it's super explosive.
It's also not found in pure form in any quantity on earth; separating from Methane/Ethane, which would be one of the easiest ways to do so, takes more energy to split than just burning the Methane/Ethane itself.
In the lab or enclosed area yes. That is where the H2 explosions are a concern. Why do you think there is an emergency vent line to the roof for a H2 cooled generator at a large power plant? H2 is used by most large generators at nukes or natural gas units.

They work up to about liquid N2 temperature which may be kinda enough, but these materials are difficult to make into wires if I recall correctly. There is stuff that works at higher T, but only under very high pressure.
Well, back in April he released a film on Youtube that was critical of the corruption of the environmental movement. Titled 'Planet of the Humans', it rips into the environmental damage renewables cause, the takeover of the movement by the wealthy, etc. He didn't direct it.
Even before it was released, they started getting pressure not to...by the powerful people in 'the movement' who get skewered in the film.
This controversy died when COVID came on the scene, but the damage was done. But now it is coming back in the limelight, starting with an investigative report on it was released last week: https://thegrayzone.com/2020/09/07/green-billionaires-planet-of-the-humans/
