In its latest earnings statement, Gevo Inc., a renewable chemicals and advanced biofuels company, mentioned a report by the National Marine Manufacturers Association identifying isobutanol as a possible gasoline blend stock for the marine industry as a "highlight" of its fiscal year.

“Gevo’s 16.1 percent isobutanol blend was compared to standard engine testing gasolines in both emissions and product tests. The NMMA report concluded that isobutanol can be blended into gasoline at higher percentages than ethanol and, unlike ethanol-blended gasoline, isobutanol blends do not cause phase separation when water enters the fuel system,” the company said in its earnings release.

“We are on the cusp of commercializing renewable isobutanol,” CEO Patrick Gruber said in a statement. “The retrofit of our Luverne plant continues on track to start commercial scale production of renewable isobutanol in the first half of this year. We are incorporating our learnings from this retrofit into the ongoing detailed design of the Redfield Energy retrofit in South Dakota.”
