Why hydrogen gas does not use in domestic fuel? Chemistry
The infrastructure to distribute and dispense it is very expensive. Also, the cost to rip the H2 molecules apart from the O in water costs even more energy than you get from the hydrogen gas. [ So it actually pollutes more when you factor in the oil or gas it took to power the electrolysis. as well as safety issues of hydrogen embrittlement in pressure vessles, plumbing, and engine components
are big reasons it has not been adopted.
for domestic use it's just too difficult to handle compared to the simplest carbon-hydrogen compounds (like Methane).
