People who are working on biofuel projects are defending themselves to servive. Just do little bit of search on internet and you will find out the facts which will discorage you from supprting this. Hydrogen is also one of the dirtiest fuel. Hydrogen atmos are so small that they can escape from ever steel containers and damage the ozone layer faster than what grren house gases are doing to it. Wind and solar should be ultimate goal and for cars ..I just love lithium battery even though the transmission and storage losses are there.
