ENGLEWOOD, Colo., Jun 20, 2011 (BUSINESS WIRE) -- Gevo, Inc. GEVO -2.04%  , a leading renewable chemicals and advanced biofuels company, will report its progress on biojet fuel based on its renewable isobutanol to the airline industry at the Paris Air Show on Monday, June 20, 2011. Test results from its fit for purpose fuel review conducted by SRI International and the Air Force Research Lab will be presented to the alcohol jet review committee of ASTM, a globally recognized leader in voluntary standards, on June 21, 2011. The next step in setting Gevo's biojet specification will be working with engine manufacturers to complete commercial engine testing. Full certification of Gevo's biojet is expected in 2013.

"We continue supply discussions for biojet with numerous airlines seeking a cost competitive, low carbon alternative to petroleum derived jet fuel," said Christopher Ryan, Ph.D., President and COO of Gevo. "We have planned production capacity of approximately 110 million gallons of isobutanol per year in 2013 for use in the jet fuel, chemicals and other markets."

Gevo's renewable isobutanol can be converted to jet fuel using chemical synthesis already deployed in the refining industry. Jet fuel made from Gevo's isobutanol is the same as petrochemical jet fuel except that the carbon source is renewable. Gevo has successfully produced biojet from cellulosic biomass and has entered into a downstream engineering collaboration with Mustang Engineering. Gevo and United Air Lines have a non-binding letter of intent to supply biojet to the United hub at Chicago O'Hare International Airport starting in 2013.

Gevo broke ground on its first 18 million gallon per year (MGPY) retrofit in May, 2011, in Luverne, Minnesota, which is expected to begin production of isobutanol in the first half of 2012. Gevo expects to add another approximately 38 MGPY of capacity in 2012 at its second facility, a joint venture in Redfield, South Dakota, and negotiations are currently progressing on a third production facility. Gevo plans to have approximately 110 MGPY of capacity on line in 2013 and up to 350 MGPY of production by 2015.
