Power On - Hydrogen
Jon Hughes and Mark Anslow
1st November, 2007
There is much talk of the possibility of a future ‘hydrogen economy’, which will power all our vehicles and homes. It is important to remember that hydrogen is not an energy source; it is an energy carrier. To obtain hydrogen it must be split from either natural gas or water molecules. The former, most widely used, method not only requires energy but also gives off carbon dioxide (CO2) in the process. Hydrogen produced in this way requires more energy to make than will eventually be returned when it is used. It makes more sense from a climate perspective to burn the natural gas itself than to convert and re-convert it to hydrogen in this way.more...
