The Advantages of Hydrogen Fuel Cell Cars

Hydrogen fuel cell cars are pretty much as safe as driving around with gasoline, which is also a completely combustible thing. The safety issues are probably not a deal breaker for hydrogen, but it's got to be compressed and stored under pressure. And the batteries will never match the energy density. But here's the thing, because we already have an infrastructure for liquid fuels, the ability to make ethanol or propanol from, directly from sunlight could have, could be serve a niche, I think.
