El Register has a piece on the development of a technique to extract hydrogen from the hydrocarbon chains in sunflower oil.
The technique does result in some carbon dioxide being released, but the team points out that growing sunflowers would offset it.
Dupont explains that the team uses two catalysts to extract the hydrogen in a process known as unmixed reforming. One catalyst is carbon based, and the other contains nickel. The reforming process means the team does not reply on fossil fuel at any stage in the process.
