I don’t think that hydrogen is going to be a satisfactory alternative. We need to get out of the mindset of choosing finite resources (we only have a finite amount of hydrogen on earth). We end up just moving the problem down the road. Remembering that the water on our planet is finite and it’s a thin skin on the surface of the Earth should be sobering. Remembering that every hydrogen transaction is lossy. And every hydrogen escape is a permanent loss to the planet.
It’s the same with nuclear. Hydrogen is not renewable, nuclear is not clean.
Much of the energy we use is tied up in cars – they’re horrendously inefficient. Not just in the energy conversion (~70% loss) but in the transportation of 100 kgs of human, we have to also transport 900 kgs of car (and that’s for an average one). So, when you think about it, only 3% of the energy we put in the tank is used to transport a human. Electric cars won’t save us from this – they’re a band aid (and they’re even heavier)
(I question the symbolism of Wrightbus in the photo. I question the commitment of the minister from a party of climate-disruption denialism. I question the use of hydrogen for storage – after all, it’s not like hydrogen under pressure has been a problem in the past.)
Take the long view. Build civilisations to last.
