Gevo’s Alcohol to Jet Fuel Meets Approved ASTM Standard

ENGLEWOOD, Colo., March 28, 2016 (GLOBE NEWSWIRE) -- Gevo, Inc. (NASDAQ:GEVO), announced today that ASTM International Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants and Subcommittee D02.J on Aviation Fuel passed a concurrent ballot this week approving the revision of ASTM D7566 (Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons) to include alcohol to jet synthetic paraffinic kerosene (ATJ-SPK) derived from renewable isobutanol (the “D02.J Ballot”).

As previously announced, Alaska Airlines is now poised to fly the first-ever commercial test flight using Gevo’s renewable alcohol to jet fuel (ATJ). Gevo is preparing the shipment of ATJ to Alaska Airlines for this first flight. Alaska Airlines will work with the Federal Aviation Administration to schedule the flight using Gevo’s ATJ.

The D02.J Ballot passed two levels of ASTM technical scrutiny: subcommittee and main committee ballot and is in the final stages of Society Review. The ASTM process is substantially complete as it relates to the approval of the D02.J Ballot. In order to fully complete the process, the ASTM still needs to close the Society Review, perform a final ballot tally, and publish the revision of ASTM D7566 (Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons) on its website. It is expected that these final actions will be completed by the ASTM in early April.

Once the revision of ASTM D7566 (Standard Specification for Aviation Turbine Fuel Containing Synthesized Hydrocarbons) is published by the ASTM, Gevo’s ATJ will be eligible to be used as a blending component in standard Jet A-1 for commercial airline use in the United States and in many other countries around the globe. Gevo’s ATJ would be eligible to be used for up to a 30% blend in conventional jet fuel for commercial flights.

“We’re pleased that this newly-revised standard now supports isobutanol based alcohol-to-jet aviation biofuels and we look forward to flying it this year. Developing a domestic, competitively priced, sustainable supply of biofuels is fundamental to Alaska Airline’s long term sustainability goals,” said Joe Sprague, Alaska Airline’s Senior Vice President of External Relations.

Dr. Patrick Gruber, Gevo’s Chief Executive Officer, commented, “This ASTM revision is a major achievement and supports one of Gevo’s key products. We believe that Gevo’s renewable ATJ provides a clear and cost-competitive path for commercial airlines to reduce their greenhouse gas footprints and reduce their particulate emissions from combustion. For Gevo, this step is expected to open a large and significant market to Gevo around which Gevo expects to build a profitable business.”
