Hydrogen is the most common element in the universe and could potentially be used as an inexhaustable source of fuel, even with current internal combustion engines (ICE). There are several sources of hdrogen, but the most common one is that or water, which is easily accessible and also available in limitless quantities. Since water is the most easily accessible source of hydrogen as a fuel, I have established a separate page for Water Fuel, Water as Fuel.
Hydrogen as fuel, and the "Hydrogen Economy" became of great interest back in the 1970's when the oil embargo was established, but more recently due to concerns that petroleum and gas based fuels will run out in the near future, and also even more recently, that fossil fuels are contributing to global warming.
But the hydrogen economy pundits are almost "all" stuck in the "gasoline station" model of providing hydrogen to consumers, whereby there would be hydrogen fuel stations that people would drive into, like gasoline stations, and fill up their car with stored hydrogen gas, or quickly exchange their empty hydrogen gas tank with a full tank of hydrogen gas, as is currently done with trailer propane tanks. But hydrogen filling stations would require billions of infrastructure to put in hydrogen pipelines all over the country to supply the filling stations. Or else, it would require huge numbers of hudrogen fuel trucks to deliver the hydrogen gas tanks to stations all over the world.
Both methods are a huge waste of time and money, when all that needs to be done is to develop a small converter to be put under the hood of a car that would convert water, or some other cheap, hydrogen based substance, to hydrogen, which would then go to the ICE, or else be run to a hydrogen fuel cell on one side with oxygen going to the other side and then combining to produce electricity to run the car.
But strangely, none of the advocates for the hydrogen based economy are even considering such a conversion device. But I do believe it is possible, and may already have been invented.

1. How did the Germans produce hydrogen for some of their trucks in World War II?
2. Try to find German patents on hydrogen production;
3. Is hydrogen peroxide a viable source of hydrogen?
4. I think I read somewhere that hydrogen peroxide (H2O2)has been used as a fuel for rockets, helicopters, etc by the Germans, and others. Find these references.
