Hmm… a Bush-eraDOE biofuel initiative is showing some promise, it seems :
Pate’s presentation, “The Promise and Challenges for Algae Biofuels: Overview of Approaches and Issues for Sustainable Production Scale-up,” will cover many of the current issues surrounding algae research and development. Algae is emerging as an attractive resource because it reproduces quickly, uses large quantities of carbon dioxide and can thrive in non-freshwater, including brackish and marine water, thus avoiding competition with traditional agriculture’s freshwater needs. In addition, algae can produce biomass and oils, and is attractive as feedstock for renewable fuels, with potentially greater productivity and significantly less land use requirements than with other commodity crop feedstocks such as corn, soy and canola.
In recent assessments that build on earlier work done under the DOE-funded Aquatic Species Program during the late-1970s through the early 1990s, Pate and others have been taking a new look at the nation’s potential for algae biofuels production capacity development and resource requirements. The U.S. has ample sunlight, lower value land and non-freshwater resources in the lower latitude coastal and inland states, including the Southwest region of New Mexico, Arizona and California, to potentially produce large volumes of biofuel feedstock, if high productivies can be reliably achieved.
With algal oil productivities that could potentially reach annual average levels in the range of 3,000 to 5,000 gallons per acre, the land footprint required for large volumes of renewable fuel production would be minimal when compared with other conventional oil crops, such as soy and canola, that produce between 50 and 120 gallons per acre per year.
“With algae, we’re talking about annual average productivities that could reach several thousand gallons per acre per year — with practical values that analysis has shown might be able to reach more than 6500 gallons per acre — so if you do the math, you can see the reasoning behind this research,” Pate said.
Neat, assuming this isn’t just PR.
