Dear Daniel:

The energy density of gasoline when converted to mechanical energy via IC engine is at most 15 Kwh per gallon whereas 1 gallon of LiH (liquid Hydrogen) gets about 30 Kwh due to higher fuel cell efficiencies. Of course, fusion would take this to 300,000,000 Kwh.

Storing LiH (pronounced "lie") is easy. The larger the tank, the less losses per unit stored and when you bury it, the ground acts like a far better insulator further reducing losses. Alternatively hydrides have the safety of a non explosive storage method but, at a lower density. You have to heat the hydrides to release the hydrogen but density is about 1/3 (I think) of LiH.
