Advanced Biofuels

Like first-generation biofuels derived from corn and soybeans, advanced biofuels provide a domestic alternative to foreign oil. The benefits of advanced biofuels are that they do not compete with global food sources and they are better at reducing GHG emissions. Advanced biofuels can be both diesel and ethanol-based. They are produced from a variety of biological sources including: leftover agricultural and forestry materials, algae, municipal waste and perennial plants grown specifically for energy production. These biomass sources are more difficult to break down into ethanol or diesel than first generation sugars, starches and oilseeds. A number of technologies are being developed to refine this cellulosic material. At this point, however, there are no commercial-scale plants producing advanced biofuels, and no technology or source has emerged as the industry-leader.
