The Hydrogen Economy - It doesn't add up

The Lucerne Fuel Cell Forum have announced that they will no longer be discussing hydrogen fuel cells as they see them as a dead end (there are many other types of fuel cell as well that are more promising). Their logic seems so obvious, why havn’t we spotted it before?

It goes like this. We have electric cars that are powered from electricity produced by a fuel cell that was powered by hydrogen. All good so far. Hydrogen does not occur naturally in accessible form, so we make it by using electricity to split water into it’s components oxygen and hydrogen. So the starting product is electricity and the end point is electricity and hydrogen is the storage medium. Well that seems fair enough, you have to move the electricity somehow. The real problem is efficiency. If you were to take the electricity and store it in a battery in your car, you would get about 80% efficiency in terms of the energy you put in to the energy you got out. If you go the hydrogen route you only get about 30% by the time you have converted into hydrogen, compressed and distributed it and run the hydrogen through the fuel cell. So the reason we don’t just stick with batteries is...?
