... fossil fuels. The stumbling block on this path is efficient and lightweight storage of enough power to parallel fossil fuel vehicles already in use. To date, there has been no storage system that can produce enough power to economically and safely power a vehicle for realistic use. Hydrogen is the most plentiful element on the planet. Most alternative energy experts agree that hydrogen is the frontrunner in alternative fuels. There are several methods that are being explored for hydrogen storage and use in transportation. These include compressed hydrogen gas, liquid hydrogen, methanol, and solid chemicals from which hydrogen is released (sodium hydride (NaH) and sodium borohydride (NaBH4 )). There are several methods that have serious hazards associated with their use. Compressed hydrogen gas would not be practical for normal transportation methods, since pressurized cylinders of these gases would be bulky, dangerous, and unwieldy to refill. Liquid hydrogen storage ...
