Auburn Researcher: Biofuels Are Still an Important Component of Our Energy Mix
by Steven Taylor (Yellow Hammer) … But for a moment, let’s reexamine biofuels, as they can still play an important role in our state’s energy production and economic development. According to the Energy Institute of Alabama, our state ranks fifth in the nation for electricity generation from biomass-based fuels. Biomass consists of plants or plant-based materials such as agricultural crop residues, forest residues, or dedicated energy crops such as switchgrass or fast-growing trees. These various sources of biomass can be used not only for generating electrical power or making liquid transportation fuels like gasoline or diesel fuel, but they can create a wide array of co-products like plastics and adhesives.
Here at Auburn University, we are conducting research to maximize the usage of biomass for conversion to biofuels and valuable co-products. While most people think of corn-based ethanol when biofuels are mentioned, researchers at Auburn are advancing the technology to convert grasses, pine trees and hardwoods to gasoline, diesel, and jet fuels. And to make the fuel production process more economically feasible, we are developing a suite of co-products that can be produced at the same time.
Auburn researchers are also tackling the challenge of capturing gases emitted from landfills. Currently, it’s cheaper to flare the landfill gas than it is to clean and transport it to another location for re-use. Our faculty have developed methods to remove unwanted sulfur from the gas which then makes the gas valuable for production of electrical power or liquid fuels.
Additional research has developed smaller-scale, more cost-effective reactors that can convert this gas to gasoline and diesel. READ MORE
