I believe that the fuel tank for hydrogen would have to be pretty large. It would take up the space that is used for passengers now, if you wanted any kind of range. You can use liquid hydrogen to minimize the space, but that would require energy to maintain the low temperatures. And you wouldn't want to store such a vehicle in your garage. Inevitable leakage of hydrogen can fill the garage with inflammable hyrdogen gas. Think the Hindenberg... Certainly, engineers are working on these issues, I would imagine.

I looked at possibly generating hydrogen gas at home through electrolysis as long-term energy storage that could be stored in tanks as gas outside, perhaps in the ground. It's not feasible at all, but I keep it in the back of my mind in case the Dims go full mark-of-the-best with their energy policies.

I have enough solar and battery storage to provide 81% of all the power we consumed in the past 365 days, with most of the 19% power pulled from the grid during the winter months from mid-November to mid-March. I can live with the system as is unless the Dims make it so that the only way I get the other 19% from the grid is if I join their cult. Every now and then I sit down and do the project engineering for what it would take to make the home more energy efficient and improve on solar and battery storage if it came down to having to be off-grid. Hydrogen storage has the benefit of being able to sit in tanks for half a year without degrading like battery power would (batteries losing charge just sitting). But generating the hydrogen gas through electrolysis, then using the gas to power a fuel cell when needed is a very inefficient round trip for power. I wouldn't get back nearly as much power as I consumed creating the gas.
