Hydrogen Fuel Station in Iceland
klang points to this blurb about Iceland opening a hydrogen refueling facility. While it isn't, as the blurb states, the world's first hydrogen station, it is notable because it produces the hydrogen onsite with electricity from geothermal energy and electrolysis, making it an almost perfectly clean energy source.
Burning hydrogen creates about an electron volt of energy per molecule or so. FUSING hydrogen into helium, what a hydrogen bomb does, generates several MILLION electron volts of energy per atom. So unless you have a hydrogen tank for your car that is at EXTREMELY high pressure, you don't have a hydrogen bomb. There are dozens of chemicals that generate far more explosion energy for a chemical bomb, such as, say, GASOLINE!

IMHO, Algae is the most likely source of renewable hydrogen in the foreseable future.
