Where is the Hydrogen Technology headed?
There are two paths: Hydrogen Combustion Engine & Hydrogen Fuel Cell.
Which of the two technology is practical for real world application (e.g. energy for transportation vehicles)?

A Hydrogen combustion engine would be constrained to about 30% efficiency whereas a hydrogen fuel cell should be in excess of 95% efficient. However a hydrogen fuel cell requires very pure hydrogen and oxygen or it's quickly fouled. Either way, current commercial hydrogen is stored in heavy steel containers at 2,100 psi ( 150 bars ) of pressure and at that pressure occupies 20 times the volume of an equivalent amount of energy in gasoline. This limits the range of the vehicles and is not only a weight penalty for the steel pressure vessel but a safety risk. The idea of a hydrogen economy is to temporarily store energy chemically from other sources such as solar, wind, hydro, tidal, wave, geothermal and nuclear for use in vehicles but is hydrogen even necessary to achieve this?
When Sandia Labs investigated more efficient means of procuring hydrogen from H2O, they realized that the process would also produce carbon monoxide from CO2. This is important because a mixture of CO and H2 is called syngas from which we regularly produce linear hydrocarbons such as gasoline and diesel. Therefore, you don't need hydrogen, synthetic gasoline and diesel can serve the same function without replacing a single vehicle. Of course, this wouldn't sell new vehicles the way hydrogen or EV's would.Source(s): https://share.sandia.gov/news/resources/releases/2... http://www.sandia.gov/LabNews/090410.html

I just found out today about HHO Fuel Systems. They look very, very good. Non-toxic, Nonpolluting, cleans inside the engine, and the list go on and on. It can easily be made at home and put on (Any) car or truck; increasing fuel efficiency from 30 to 90%. example 12 mpg to 33 mpg, or 30 mpg to 80 mpg. Rain water is free and exactly what it runs on.Source(s): goggled - HHO Fuel Systems
