Hydrogen is less energy per volume than gas, it requires pressure vessels rather than tanks, it's stored pressurized in vehicles and stations, it makes materials it contacts brittle, it relies on a manufacturing process that either requires natural gas production or a huge excess of electrical energy, fuel stations are huge capital costs, etc.
I could go on, but it just doesn't make sense to pin hopes on hydrogen.
- bhhaskin 4y agoThe exact same thing can be said about EVs and then some. Batteries are less energy per volume than gas. Batteries are extremely hazardous if damaged. They have a relatively short lifespan. They are hardcore industrial hazardous waste. Power generation is likely coming from a gas power plant or even a coal power plant. The required infrastructure upgrades would be astronomical.
