It seems like your Bio Diesel Cell ought to be registered as equivalent to Forestry's Ethanol. SirSengir changed the name of the former Biofuel, you see. Or did I miss something? Right now, Diesel Cell is equivalent to Fuel, after all.
Edit: I just realized that oceans will soon be my best resource... Can't wait for Eloraam's next update. I'll have a Tetrahedron-shaped sky fortress pumping water up through a tacky wool "syphon-hurricane". Assuming Frame movement doesn't break everything, of course. How well do GregTech machines work with Frames, btw?
