Fueling Cars with Water: Korean Research Team Develops Tech to Mass Produce Hydrogen

5. I maybe wrong but I don't believe that the laws of physics

allow much wiggle room on making the electrolysis of water for the production of hydrogen much more efficient then it already is.

Having said that producing hydrogen with electricity for use as an energy carrier to power vehicles is not efficient or cost effective. Using electric vehicle at this point in time is much more efficient.

The energy required for electrolysis to convert water to hydrogen, then compress it , then convert it it into either mechanical energy through combustion or back to electrical via a fuel cell then to mechanical via electric motors has inefficiencies.

The most cost effective method of producing hydrogen in volume is by reforming natural gas by adding thermal energy (steam) to convert it to hydrogen and carbon byproducts and even that method makes it cost ineffective.
