ENGLEWOOD, Colo. - January 17, 2013 - Unites States Senator Mark Udall of
Colorado toured and met with Gevo, Inc. (NASDAQ: GEVO) yesterday to discuss the
importance of alternative energy technologies for Colorado and the U.S. economy.

Senator Udall met with Chief Executive Officer Patrick Gruber, Ph.D. to discuss
renewable energy options and see first-hand the innovative research and
development Gevo has done that will enable it to be a leading provider of
renewable chemicals and biofuels.
The Colorado-based company's commercialization efforts are focused primarily on
isobutanol, a four carbon alcohol, and its derivatives. Isobutanol is an
important platform chemical with broad applications in large chemicals and fuels
markets and a "drop-in" product that should allow customers to replace
petroleum-derived raw materials with renewable isobutanol-derived raw materials
without modification to their equipment   or production processes. Isobutanol can
drop into existing infrastructure, providing for straightforward integration
into existing refining and petrochemical production processes.

Gevo's isobutanol has successfully cleared registration with the U.S. EPA as a
fuel additive, is the first isobutanol to be listed in the EPA's Fuel
Registration Directory, and is now approved for blending with gasoline.
Additionally, Gevo worked with the United States Air Force (USAF) last June to
provide fuel for the first successful "alcohol-to-jet" (ATJ) fuel test flight in
an A-10 Thunderbolt II.

"Some of the best clean energy thinking in the country, and in fact, the world,
is coming out of Colorado," said Gruber. "Gevo is a prime example of how
Colorado is a hotbed for development of technologies that solve tomorrow's
renewable energy challenges today. We are very pleased that Senator Udall is
such a staunch advocate for the renewable energy industry and that he was able
to see some of the process technology that makes Gevo a leading renewable
chemicals and advanced biofuels company."

Senator Udall remarked that it was a treat to visit Gevo. "I see every day the
cost of being so dependent on foreign sources of oil," he said. "What I love
about what Gevo is doing is they're helping create a future where we won't be so
dependent, where the U.S. can maintain our superiority and, in the process,
enhance our national security, keep innovating, and create jobs. Gevo is brewing
new formulas, materials, and chemicals for the fuels of the future."
