KiOR Ships First Cellulosic Diesel

World's First Renewable Diesel En Route to American Vehicles

PASADENA, Texas, March 18, 2013 (GLOBE NEWSWIRE) -- KiOR, Inc. (Nasdaq:KiOR),
today announced the initial shipments of cellulosic diesel from its first
commercial-scale facility in Columbus, Mississippi.

KiOR's facility uses pine wood chips previously feeding a shut down paper mill
at Columbus and produces gasoline and diesel, the first renewable hydrocarbon
fuels in the U.S. manufactured at commercial scale and derived solely from
non-food feedstocks to avoid competition with human food needs. Unlike
traditional biofuels like ethanol or biodiesel, KiOR's fuels have no
compatibility issues. KiOR's renewable gasoline is also the first renewable
cellulosic gasoline ever registered by the Environmental Protection Agency for
sale in the U.S.

"This is a major step forward for KiOR, the biofuels industry and the entire
renewable fuels sector," said Fred Cannon, KiOR's President and Chief
Executive Officer."With first production at Columbus, KiOR has technology
with the potential to resurrect each and every shut down paper mill in the
country and to replace imported oil on a cost effective basis while creating
American jobs. This facility demonstrates the efficacy of KiOR's proprietary
catalytic biomass-to-fuel process with the potential to deliver cellulosic
gasoline and diesel to the U.S. We are proud to be making history in
Mississippi. The technology is simply scalable and we believe sufficient
excess feedstock exists in the Southeast alone to build almost fifty KiOR
commercial scale facilities."

Condoleezza Rice, former U.S. Secretary of State and a current member of
KiOR's Board of Directors, added, "KiOR is changing the American energy
equation by innovating and commercializing an entirely new generation of
hydrocarbon-based diesel and gasoline fuel. By making the promise of
cellulosic fuels a reality, KiOR demonstrates that these fuels are an
attractive option for lessening America's dependence on foreign sources of

Haley Barbour, former Governor of Mississippi, who was instrumental in
attracting KiOR to Mississippi, remarked, "The shipment of this first fuel
fromKiOR's Columbus, Mississippi, facility is the culmination of a vision to
establish Mississippi as the birthplace of the wood-to-fuels production
technology. This progress highlights our highly skilled labor force, abundant
natural resources and supportive government climate for innovative companies
like KiOR seeking a home to expand their businesses.Mississippi has partnered
with KiOR throughout this history-making project, contributing economic
development support ranging from research and testing projects within our
world class universities, to technical training within our superb community
college system."

Major benefits of KiOR fuels include:

  *Fuels are identical to petroleum based fuels made from conventional
    methods and will drop in to the existing fuels infrastructure.
  *Studies show that KiOR fuels will have a significant reduction in
    lifecycle greenhouse gas emissions when compared to fossil-based fuels.
    KiOR fuels in today's engines can provide a carbon emissions profile that
    is comparable to or better than electric cars run off the U.S. electric
  *Construction and operation of production facilities provides significant
    economic development in rural areas.
