Solazyme Produces World's First Algal-Based Jet Fuel

- Fuel Passes All Tested Specifications Including the Most
Critical ASTM D1655 Specifications -
SOUTH SAN FRANCISCO, Calif.--(Business Wire)--
Solazyme Inc. announced that it has produced the world's first
microbial-derived jet fuel. Solazyme's algal-derived aviation fuel as
analyzed by the Southwest Research Institute (SwRI), one of the
nations leading fuel analytical laboratories, passed the eleven "most
challenging specifications needed to meet the ASTM D1655 standard for
Aviation Turbine Fuel. The tested areas included the key measurements
for density, thermal oxidative stability, flashpoint, freezing point,
distillation and viscosity among others. Of the eleven tested
parameters, the Solazyme aviation fuel passed the ASTM D1655
requirements for every measurement. Therefore, the Solazyme
algae-based aviation kerosene has passed the biggest hurdles needed to
successfully develop a commercial and military jet fuel fully
consistent with existing engines and infrastructure," as stated in the
SwRI report.

In the U.S. alone, 1.6 billion gallons of jet fuel are used every
month resulting in significant greenhouse gas emissions. Additionally,
the EU is widely expected to require airlines flying into and out of
airports in the EU to participate in the Emissions Trading System
beginning in 2011. As a result, the need for environmentally friendly
and sustainable alternatives is growing rapidly. Solazyme's
algal-derived aviation fuel is the first step towards achieving those
alternatives on a broad scale.

"We are excited to be the first advanced biofuel company to
successfully make jet fuel from algal oil that passes the most
critical ASTM D1655 (Jet A) standards. Producing a low carbon jet fuel
and putting it through biofuel testing with SwRI further solidifies
Solazyme's position as a leader in the green fuels space," said
Jonathan Wolfson, chief executive officer of Solazyme. "This
announcement is proof of the advantages of our proprietary renewable
oil production process to create highly tailorable oils and renewable
fuels."

Solazyme is currently producing thousands of gallons of oil at
scale and is the only advanced biofuels company that has produced
fuels that have passed specification testing. The fuels produced in
addition to jet fuel include Soladiesel(BD)(TM) a FAME biodiesel and
Soladiesel(RD)(TM) a renewable diesel, which has the same chemical
properties as petro-diesel. Like Solazyme's aviation fuel, both
Soladiesel(TM) fuels are compatible with the existing transportation
fuel infrastructure.

Solazyme implements a unique algal conversion process that allows
algae to produce oil in large tanks quickly, efficiently and without
sunlight. The process can employ a variety of non-food feedstocks,
including cellulosic materials such as agricultural residues and
high-productivity grasses including bagasse and switchgrass as well as
industrial byproducts such as crude glycerol. The results are
renewable oils that can be leveraged across a wide variety of
industries and applications, which are nontoxic and safe.
