content: Exactly. Hydrogen is like a battery. Except it's light, doesn't degrade (1 Kg of H2 stored properly now will be the same in 10,000 years) and it's eco friendly when made with renewable resources like solar panels. This is why you'll see Hydrogen Trucks before battery trucks. Also, anyone can make hydrogen. Honda has been working on Home Solar Hydrogen units and will probably have one on the market when they introduce their new Fuel Cell car next year. http://world.honda.com/news/2010/c100127New-Solar-Hydrogen-Station/
