In addition to being produced from steam reforming natural gas, hydrogen must be pressurized to be used in fuel cells (hydrogen at ambient pressures is not useful aside from making a pop when you put a flame to it). One can produce hydrogen gas from standard electrolysis, but it takes a lot of energy to pressurize it into a useful medium. Hydrogen that is produced from natural gas, is already produced at high pressures.
Currently, the hydrogen economy is a myth. I'm not saying it won't ever be viable, but there are a lot of misconceptions out there about it.
Additionally, the use of biofuels as a major fuel source is a myth. The only reason that area is around right now is because it's heavily subsidized by moron politicians who fired their scientific advisers.
