Algae biofuel reduces CO2 emissions by 68pc more than petroleum counterparts: Study

Washington, Sept 20: A recent study has revealed that algae-derived biofuel can reduce CO2 emissions by 68 percent, as compared to petroleum fuels.


The study published by Algae Biomass Organization (ABO) showed that algae biofuel is approaching a similar Energy Return on Investment (EROI) as conventional petroleum.

The study concluded that the environmental and energy benefits of algae biofuel are at least on par, and likely better, than first generation biofuels.

ABO's Executive Director Mary Rosenthal said algae-based fuels will be a long-term, sustainable source of fuels with significant emissions reductions, a positive energy balance, nutrient recycling and CO2 reuse.

The system that was evaluated recycles nutrients, can accept an algae feed that is up to 90 percent water in the processing phase, and the final product can be blended with refinery intermediates for refining into finished gasoline or diesel product, resulting in significant energy savings throughout the process.

Researchers said that expected improvements in the industry meant that algae-based biofuels are set to surpass advanced biofuels, such as cellulosic ethanol, in terms of both energy returns and greenhouse gas emissions.
