SOUTH SAN FRANCISCO, Calif. -- March 5, 2013

Propel Fuels (, a leading retailer of renewable fuels and
clean mobility solutions, and Solazyme, Inc. (NASDAQ: SZYM), a renewable oils
and bioproducts company, today announced that sales and survey results from
their 30-day retail pilot program show consumers prefer its environmental
benefits compared to conventional fuels; would purchase more of it if it was
widely available and would even pay a premium for it. The pilot program, which
marked the first commercial availability of algal derived fuels, offered
Soladiesel[BD] in a B20 blend to consumers through Propel’s Clean Fuel Points
in Redwood City, San Jose, Berkeley, and Oakland.

In the consumer survey, 92 percent of participants noted that they would be
more likely to purchase algae-derived fuel for its environmental benefits; 70
percent indicated that they would purchase the fuel more frequently if it were
derived from algae; and nearly 40 percent of customers indicated they would
pay a premium for algae-derived fuel.

Sales results reflected the enthusiasm indicated by the survey, with a 35
percent volume increase at Propel stations offering the algae-derived fuel
over area sites not participating in the pilot.

“Our fuels have already been successfully demonstrated in fleet vehicles,
corporate buses, military applications and the first U.S. commercial flight on
biofuel,” said Bob Ames, VP of Fuels, Solazyme. “The successful pilot program
with Propel further exhibits strong consumer appetite for the superior
performance and environmental properties of Soladiesel.”

Solazyme’s high quality algae-based Soladiesel[BD] meets or exceeds ASTM
quality specifications and has shown performance enhancements including
superior cold temperature operating performance and environmental benefits.
Life Cycle Associates, an independent greenhouse gas measurement firm,
determined that Soladiesel® provides an 85-93% greenhouse gas emissions
reduction when compared to conventional petroleum-based diesel. In addition,
testing by the National Renewable Energy Laboratory (NREL) indicates that in a
20 percent blend, Soladiesel[BD] significantly outperforms ultra-low sulfur
diesel in total hydrocarbons (THC), carbon monoxide (CO) and particulate
matter tailpipe emissions. This includes an approximate 30 percent reduction
in particulates, a 20 percent reduction in CO and an approximate 10 percent
reduction in THC.

“Propel is committed to providing drivers true choice at the pump by bringing
to market the world’s highest quality and most sustainable fuels,” said Matt
Horton, CEO of Propel Fuels. “The results show strong preference for
algae-based fuel, and we are thrilled to have partnered with Solazyme to
enable our customers to be the first in the country to purchase this next
generation biofuel.”
