More or less, one of my projects was working on this. Certain types of algaes will grow some lipids for an energy source if they lose daylight for some reason. Those lipids (fats/oils) can be extracted for biodiesel. Algae's growing cycle is like 15-20 days too, so it's a pretty abundant harvest.
Very interesting problems associated with it too.
