Okay not driving it around then. But somehow it's worse. You still have to build the special tank and the special pump and also get an electrolysis device that is big enough to create enough hydrogen and also you have to get heaps of power somewhere that could instead be just straight put into a battery in a car. Make it make sense. What's the point? Who is willing to do that?

Don’t forget keeping everything cold enough.

On the vehicle side, you can make a gasoline tank in pretty much any shape you want. We have lots of experience making batteries in different shapes thanks to cell phones.

High-pressure tanks only want to be in one shape. And it’s not especially convenient.

Is the shape round? I bet it's round.

Ultimately, it's shrapnel-shaped.

		Is that shrapnel arranged in a roundish pattern?

Batteries create a lot of toxic waste. I'm willing to live with that if it doesn't cause climate change but there is an advantage to hydrogen? What is the impact of H2 fuel cells?

		Batteries do not create a lot of toxic waste and are essentially fully recyclable. The lead in automotive lead acid batteries today is almost entirely recovered and remanufactured into new batteries.
