Um I think you need to do more research.
I’m taking about on demand hydrogen fuel production with water.
1 gallon of distilled water gets ~400mpg.
It’s safe as there is no storage of the gas as it’s produced on demand.
Can be diy with 2 mason jars & simple parts.
Via Electrolysis or Steam Reforming? I am highly skeptical your 1 gallon input for 400 miles output in any production vehicle
Electrolysis & we are talking Prius cars
So, as a person who has used electrolysis to produce hydrogen, I can tell you that DYI units are typically low temperature and pressure, and that means really low energy conversion efficiency. If you are referring to these YT “hydroxy” production rigs, that is not only exceptionally dangerous, but ineffective at fueling any real power producing engine or fuel cell. We can review the chemistry and math involved if you wish, but hydrocarbons or anhydrous ammonia are much more dense methods to store hydrogen energy.
