Patent Picks: Biofuels
Beginning in 2005, the federal government mandated that transportation fuels sold in the U.S. contain renewable fuels, typically ethanol added to gasoline or biodiesel blended with petroleum. So it’s perhaps not surprising that data from Chemical Abstracts Service databases indicate that research and commercialization of biofuels have been heating up in recent years. The data demonstrate that interest has already shifted from first-generation biofuels—such as biodiesel or ethanol produced from the sugar or starch of food crops—to the next wave, including cellulosic ethanol (produced from crop residues and dedicated biomass crops), biobutanol, and algae-based biofuels. Evidence of that shift is highlighted here.
Patent Picks is a collaborative effort by C&EN and CAS. This feature reports on trends CAS scientists observe from patents in the CAS databases, which now generate more than 70% of the new substances appearing in the literature.
