Gevo, Inc. has applauded Underwriter Laboratories (UL) decision to approve the generic use of up to 16 percent isobutanol (biobutanol) in UL 871A pumps manufactured by any company that meets ASTM specifications. If a retail gasoline station currently has these pumps, then no changes need to be made to offer consumers isobutanol.

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.”
