That sounds fun. Not only are we already losing ton of energy to create the hydrogen, we can now lose even more and make it more expensive by trying to liquefy/compress it to make it somewhat transportable. [1]
Also, almost 90% of humans living in the northen hemisphere will surely not cause any issues to this plan. [2]
The article says the ones it talks about do. Also, rotating panels can’t stop days from being shorter during winter.
And this involves only driving in summer when there is excess energy? Or getting through winter by storing enough hydrogen to make the Beirut explosion look like a firecracker in comparison?
So what are you saying exactly? With what issue would using hydrogen help?
