Gevo’s Isobutanol Cleared for Use in On-Road Vehicles in Arizona

ENGLEWOOD, Colo., May 23, 2017 -- Gevo, Inc. (NASDAQ:GEVO), announced today that a bill recently signed by Arizona Governor Doug Ducey will let gas stations sell isobutanol-blended gasoline for on-road vehicles, enabling higher performing finished fuels with renewable content for drivers in the state. 

Bill HB2368 permits isobutanol to be used as an oxygenate in gasoline for on-road vehicles in Arizona. The new law takes effect in August 2017. While the law authorizes the use of isobutanol-blended gasoline for on-road vehicles, Gevo’s isobutanol is already being sold in Arizona for off-road applications such as boating, ATVs, motorcycles and landscape equipment.

Isobutanol is an ideal renewable gasoline blendstock because of its high energy content, high octane, low water solubility and low volatility. Gevo’s isobutanol meets the ASTM 7862 specification that covers isobutanol blends with gasoline.

“We’re excited that this bill will open up a new market for our isobutanol in Arizona. With our distribution partner Musket already serving marinas, Gevo is ready to take advantage of this new opportunity to expand isobutanol sales in the state,” said Dr. Patrick Gruber, Gevo’s Chief Executive Officer.
