I drove 1800 miles in a Hydrogen Car

I don't think FCEVs will provide much benefit over battery storage. They have limited range and you absolutely need a hydrogen station to fuel them, or I guess if someone could figure it out, you could use a mobile fuel station for emergencies. With an EV, you can at least use a regular 120v outlet to get some range in a pinch. FCEVs also have much shorter range than EVs. You can also recharge an EV at home, and renewable energy sources provide energy that can be used more or less directly, rather than using an intermediate fuel (hydrogen). Hydrogen fuel stations are also crazy expensive.
