liquid hydrogen

Which new car energy technology would you bet your money on ?

 

Its a terribly exciting time for alternative car energy and many technologies are fighting it out for domination in the future. Some are very experimental while others are already available. The list is not small making the debate quite complicated. Which of the following would you bet your money on? And why? Or perhaps you have one not listed below:

Electric Hybrids & Car batteries
Plug-in Electric Hybrids
All Electric
Bio Fuels
Liquid Hydrogen
Hyrdogen Fuel Cells
Ultra-capacitors
Coal based synthetic or Coal-to-liquid

Do fuel cells hold a formidable advantage over liquid hydrogen kept at harsh below freezing temperatures ?

 

Fuel cell technology being developed by several automakers, namely Honda and Chevy, is a non-combustion form of energy unlike liquid hydrogen which essentially uses the same engine structure as conventional cars. This require liquid hydrogen to be kept in the vehicle at 420 degrees below zero which is costly. In fuel cells, hydrogen based cells are kept on stacks. A hydrogen – oxygen reaction creates electricity that powers the car. The fuel cells are refilled with the hydrogen chemical.
