Hydrogen
A community about hydrogen and its use as a way to fight climate change.
It’s always a worthwhile exercise to continue research into hydrogen tech, but in the case of transport, even if we assume the holy grail of 100% green hydrogen, we are currently converting wind/solar/wave/etc power to electricity, then using that electricity to create hydrogen, for it to be converted back to electricity to power a car or truck.
It’s better to just use batteries and not have trucks carrying all that oxygen loving explosion gas under more pressure than a soda stream canister in the Titanic bar.
Depends on materials used, is the hydrogen process worse than the heavy metal mining industry?
It is at the moment as virtually all hydrogen production is created using and extracted from fossil fuels.
The amount of rare metals used in a BEV cell has been trending downwards for the past decade, so a car bought today could contain enough lithium, cobalt etc, to power multiple cars by the time those cells get recycled.
