Default Crude hydrogen electric generator?

Anyone try it yet? From my "little" research, any gen that can run on lp can run on hydrogen..... So I have zero knowledge, but I'm trying, why aren't we making household hydrogen to run generators to power our homes? Not fuel cell, just split bonds and power a generator...

It takes a lot of energy to separate hydrogen and oxygen to get the fuel...

Because storing hydrogen is difficult, expensive, and dangerous.

If you had ready access to it, you wouldn't just run it through a Honda generator, either. The only place where the technology really makes sense is in fuel cells, and the only place fuel cells really make sense are where you have another reason to stock hydrogen (e.g., you're fueling a rocket with a large transfer stage). Its only real competitive advantage is to save space and weight over batteries with comparable storage. Otherwise the efficiency losses in making the stuff far outweigh any advantages in using it.

For survival purposes, you'd be tied down to your infrastructure, and if you're forced to bug in, then you can do just fine with safer, cheaper forms of storage, like batteries, or even compressed gas.

There's been an enormous investment in hydrogen for automotive purposes with very little to show for it (e.g., https://www.driveclean.ca.gov/Search..._Fuel_Cell.php). A relative of mine manages a small hydrogen farm and some demonstrator vehicles -- and it hasn't exactly set the world on fire. Except in the bad way.

ETA: Bulk hydrogen generation involves water and natural gas, not simply cracking steam. May as well just burn the natural gas.
