Greenhouse Gas Analysis Reveals Solazyme’s Algal Biofuels Including Soladiesel^TM Reduce Field-to-Wheels (Full Lifecycle) Carbon Dioxide Emissions by More Than 85 Percent Versus Petroleum-Based Ultra-low Sulfur Diesel

SOUTH SAN FRANCISCO, Calif.--(BUSINESS WIRE)--A study undertaken by Life Cycle Associates, LLC, using the Argonne National Laboratories GREET model, concluded that full lifecycle greenhouse gas (GHG) emissions from field-to-wheels for Solazyme’s algal biofuel, Soladiesel^TM, are 85 to 93 percent lower than standard petroleum based ultra-low sulfur diesel (ULSD). The analysis also reveals that Solazyme’s advanced biofuels result in a significantly lower carbon footprint than any currently available first-generation biofuels.

“Solazyme is committed to working with the most rigorous and well-respected external experts to independently validate the real-world environmental benefits of our technologies. Part of our mandate is to ensure we are producing products that will meet our growing energy needs in an effective, green and highly-sustainable way”

“Solazyme’s advanced biofuels substantially reduce greenhouse gas emissions per mile driven over petroleum-based fuels and result in much lower carbon emissions than currently available first generation biofuels. Lower process energy inputs combined with the production of algae derived feed results in much lower GHG emissions than currently available first-generation biofuels,” said Stefan Unnasch, President of Life Cycle Associates, LLC. “With findings like these, we are confident that algal-biofuels have the potential to play a significant role in alternative fuels and are excited that such a promising technology is in commercial development.”

Additionally, testing undertaken by the National Renewable Energy Laboratory (NREL) ReFUEL laboratory shows that Solazyme, Inc.’s Soladiesel_BD^TM significantly outperforms ULSD in total Hydrocarbons (THC), Carbon Monoxide (CO) and Particulate Matter tailpipe emissions. This includes an approximately 30 percent reduction in particulates, an approximately 20 percent reduction in CO and an approximately 10 percent reduction in THC.

“Solazyme is committed to working with the most rigorous and well-respected external experts to independently validate the real-world environmental benefits of our technologies. Part of our mandate is to ensure we are producing products that will meet our growing energy needs in an effective, green and highly-sustainable way,” said Jonathan Wolfson, CEO of Solazyme. “Solazyme’s Soladiesel^TM can exploit a wide variety of non-food feedstocks including cellulosics to achieve up to a 93 percent reduction in GHG emissions. We are very pleased with the findings by both NREL and Life Cycle Associates and look forward to playing a significant role in providing the clean, renewable fuels of the future.”
