GTI teamed up with Haldor Topsoe, UPM, Andritz, Phillips 66 with U.S. Department of Energy funding on an integrated biorefinery to make renewable “drop-in” gasoline. The project converted wood into bio-derived gasoline by combining gasification and syngas cleanup steps with a unique improved gasoline synthesis process—called TIGAS—to turn syngas into gasoline.
More than 10,000 gallons of 92-octane biogasoline were produced for fleet testing. Results were excellent—there was no difference in emissions, mileage, or engine wear, and in 2015, the green-gasoline blend was registered by EPA as an approved motor fuel.
This renewable fuel has 74% lower greenhouse gas emissions than petroleum-based fuel, and the estimated cost is $2.56 per gallon.
The TIGAS™ (Topsoe Improved Gasoline Synthesis) process is commercially available from Haldor Topsoe
