Renewable Energy Access is reporting that the first closed-loop ethanol plant using manure and methane to distill the ethanol will begin operations next month.  So it's not exactly fossil free since the electricity for the plant and the agricultural inputs for the corn are fossil-based, but it's getting there, i.e. no natural gas for distillation.  They plan to build 15 more plants like it.

An ethanol plant in Luverne reported earlier in the year that it is aiming to be the first cellulistic plant in the US, not by traditional fermentation and distillation methods, but by gasifying corn stover, skipping the whole issue with breaking down cellulose into usable sugars.
