What factors led to shift away from pursuing hydrogen-powered cars in favor of electric vehicles?
In: Other
Its questionable if hydrogen can work at scale even now, The only semi economic way to generate it is to break down gas and oil in an energy intense and pricy way. Which means to be a clean source the carbon produced must be controlled, which isn’t really any better than carbon capturing a fossil power plant. Then the hydrogen must be stored in bulky high pressure tanks and you need something similar for the pipework, which is no good for transport.
Its trapped in a worst of both worlds situation where it combines the worst features of clean energy from 10 years ago with the worst features of fossil fuel. And its not clear that there is a way forward. And its increasingly got to compete with clean sources that have their issues worked out and becoming very cheap.
