New Generation of Hydrogen Fuel Cells Powers Up

An anonymous reader writes "A safer and more practical way of storing and releasing hydrogen, discovered by two Arizona State University researchers, could lead to a new type of fuel cell capable of packing 10 times more energy. The key is apparently using the alkaline compound borohydride — 'a 30% solution of borohydride in water actually contains one-third more hydrogen than the same volume of liquid hydrogen.'"

You just described every enegery storage mechanism ever created INCLUDING oil (Oil does not create energy, it simply stores solar energy collected from the sun a while back.).

The act of storing, transporting or using energy in any way involves waste (heat).

Oil & coal happen to be pretty decent storage mechanisms--relatively little waste while in storage, but somewhat difficult to recharge and creating it is quite wasteful.

So, if you are just talking about "Consuming" the energy, hydrogen is much more efficient and clean than oil. If you take into account the production of the energy as well, that's a different story. We'll have to set up some bogs and find some dinasours and wait a while before we can compare.
