New Study: Algae Biofuel Cuts CO2 >50% vs. Petroleum
(Algae Industry Magazine) Algae-derived biofuel can reduce life cycle CO2 emissions by 50 to 70 percent compared to petroleum fuels, and is approaching a similar Energy Return on Investment (EROI) as conventional petroleum, according to a new peer-reviewed paper published in Bioresource Technology. The study, which is the first to analyze real-world data from an existing algae-to-energy demonstration scale farm, shows that the environmental and energy benefits of algae biofuel are at least on par, and likely better, than first generation biofuels.
The study, “Pilot-scale data provide enhanced estimates of the life cycle energy and emissions profile of algae biofuels produced via hydrothermal liquefaction (HTL),” is a life cycle analysis of an algae cultivation and fuel production process currently employed at pre-commercial scales. The authors examined field data from two facilities operated by Sapphire Energy in Las Cruces and Columbus, New Mexico that grow and process algae into Green Crude oil. Sapphire Energy’s Green Crude can be refined into drop-in fuels such as gasoline, diesel and jet fuel. READ MORE and MORE (Algae Biomass Organization) and MORE (Climate Progress) Abstract
