Gevo, Inc., the world's only commercial producer of bio-based isobutanol, today confirmed that Underwriter Laboratories (UL) has approved the generic use of up to 16% isobutanol in UL 87A pumps by any manufacturer meeting ASTM specifications, providing all of the service stations across the country with the assurance that isobutanol blended gasoline will work in their current gasoline pumps without the need to purchase new equipment.
Gevo has been working with UL for several years to approve the use of isobutanol in UL 87A pumps. UL in working with various companies and independent laboratories compiled data for their scientific determination on isobutanol. Gevo sponsored a large study based on SAE J1681 and using a model created in a previous UL investigation with ethanol-surrogate gasoline fuel blends.
"I am very pleased with what we have accomplished with UL. They are great organization to work with in the commercialization of isobutanol," said Glenn Johnston, Executive Vice President for Regulatory Affairs at Gevo. "This removes another hurdle in the commercialization of renewable isobutanol in on-road gasoline."
