Gevo has announced that ASTM International Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants and Subcommittee D02.J on Aviation Fuel passed a concurrent ballot 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. With this approval, Gevo says Alaska Airlines will now conduct a commercial test flight using its biojet fuel.
“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.
Once the revision of ASTM D7566 is published by the ASTM, Gevo’s ATJ will be eligible to be used as a blending component, up to 30 percent, in standard Jet A-1 for commercial airline use in the United States as well as in several other countries.
Dr. Patrick Gruber, Gevo’s CEO, added, “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.”
