For anyone wondering about being at the front of the consumer hydrogen revolution (bleeding edge). It can be done, although there are no CEC home hydrogen installers. There are also rules and regulations to consider, but it looks possible.
One way to provide an alternate home electrical supply other than solar and battery is to couple a hydrogen fuel cell to a 24/240v inverter.
Fuel cell,
https://www.fuelcellearth.com/fuel-cell-products/horizon-1000w-pem-fuel-cell/
Around $6,600 AUD for 1,000W output.
While that doesn’t sound like much, over 24hrs it will produce 50% more electricity than most homes use in a day. Perhaps great when combined with a home battery. Smaller capacity battery required.
Hydrogen,
One option, LindeGas HiQ 99.995% grade.
Comes in a bottle the same as a welding gas or oxygen, nitrogen etc.

Or for those desiring green hydrogen (as the industrial suppliers typically produce their hydrogen from hydrocarbons) produce your own. $100,000 give or take plus extras.
I also found this enterprising option online.

P.S.
It may be evident why for now hydrogen as an energy source needs to be considered differently to rechargeable storage batteries. There is no hydrogen equivalent in the consumer home energy market competing with a Tesla Powerwall.
