As I have consistently argued the people most likely to make money from biofuel are not the processors and distributors (who compete directly with petroleum or other fossil fuel-based products, and so have little pricing power), but the producers of feedstock, which, like oil, is in very limited supply, and so they will have pricing power.

The most productive biofuel source is algae (see this chart). It is up to 10x more productive than other sources and some strains of algae can be up to 40% oil. Read more on ponds v. reactors and a take on Petrosun at AltEnergyStocks.
