Like INEOS Bio, ZeaChem is a hybrid that features both gasification and fermentation elements. The mechanical completion of the core of its demonstration-scale project was a highlight this year — on budget, on time.
What makes this project even more interesting is that, even after moving through lab to pilot and now demonstration, no one is talking down the potential yields of the system, which aims to produce up to 135 gallons of ethanol per ton of poplar biomass, with local growers aiming for as much as 16 tons of biomass per acre. That’s more than 2,000 gallons per acre, or four times the yields with corn ethanol.
