DOE report identifies top 10 bio-blendstocks for LD gasoline

In Washington state, the Department of Energy has released its Top Ten Blendstocks for Turbocharged Gasoline Engines report that identifies top blendstocks that can be derived from biomass and are suitable for further development and commercialization. These blendstocks are best suited for LD gasoline, boosted spark ignition (BSI) engines. The blendstocks were identified using a fuel property basis using the BSI merit function. The merit function determines potential improvements in engine efficiency, was used to evaluate the performance of candidate bio-blendstocks in blends up to 30%. Those that exceeded the efficiency of an E10 premium were included in this list. This report is aimed at biofuel researchers looking to better understand the efficiency implications of biofuels under development, as well as engine researchers who are interested in future biofuels with properties that enable more efficient engine design and operation.
