Study Finds Clear Strategies for Carbon-Negative Advanced Biofuels
A new study led by Colorado State University predicted significant climate benefits stemming from the use of current and future advanced biofuel technologies. Accounting for all of the carbon flows in biofuel systems and comparing them to those in grasslands and forests, the team found that there are clear strategies for biofuels to have a net carbon benefit. In one model in particular, switchgrass can be processed by cellulosic biofuel refinery, and the remaining byproduct, representing half the carbon, is available for carbon capture and storage. “This analysis shows a quantitatively reasoned case as to why the biofuel industry should advance, not simply as a means to provide a truly renewable source of biofuel but—when combined with carbon capture and storage—a means to actually remove carbon dioxide from the atmosphere at scale and in a viable manner,” said co-author Stephen Long, at the University of Illinois.
