A few announcements came out this past week from large chemical and energy companies about their ongoing shift to biofuels
. First, DuPont is working on making ethanol
from corn stover
with new partner Broin. Corn stover is the single largest source of low cost cellulose in this country, but cellulosic ethanol from corn stover is just part of DuPont's overall biofuel plan
. Other aspects include: "rapidly developing differentiated seeds and crop protection products that will enable greater biofuel production per acre; developing and supplying new technologies to enable conversion of cellulose to biofuels; and commercializing biobutanol as a next-generation biofuel that is significantly improved and complements incumbents," according to DuPont.
Similarly, Chevron and the National Renewable Energy Laboratory have teamed up
to work on cellulosic biofuels. This partnership's goal is a process that will better convert cellulosic biomass, such as forestry and agricultural wastes, into biofuels such as ethanol and renewable diesel
