EPA registers Joule's CO2-recycled ethanol

By Joule | September 30, 2015

Joule, a company working toward commercial-scale production of liquid fuels from recycled CO2, announced that its fuel grade trademarked Sunflow-E ethanol has been registered by the U.S. EPA for commercial use in E10 and E15 gasoline blends.

“We are approaching commercialization with a technology that is first of its kind, able to convert CO2 directly into multiple drop-in fuels," said Serge Tchuruk, president and CEO of Joule. "It is critical to prove its readiness by meeting government and industry requirements. Having secured EPA registration, our fuel grade Sunflow-E ethanol is now cleared for use."

Earlier this year Joule announced the successful third-party testing of Sunflow-E ethanol, confirming its ability to meet the following standards:

* American Society for Testing and Materials (ASTM) D4806 – Denatured fuel ethanol for blending with gasolines for use as automotive spark-ignition engine fuel

* German Institute for Standardization (DIN) EN 15376 – Ethanol as a blending component for petrol

Joule Sunflow-E ethanol is chemically identical to its traditional counterparts, but differs in the way it is produced. Joule converts CO2 to ethanol directly in a continuous process, using engineered bacteria as living catalysts rather than biomass feedstocks.  At full-scale commercialization, Joule ultimately targets productivity of up to 25,000 gallons of Sunflow-E ethanol per acre annually.

“Following a full year of production at our demonstration plant, we have achieved a several-fold advance in outdoor productivity," Tchuruk said. "Additionally, we have reached unprecedented levels in our lab reactors, and we know the steps required to replicate these results outdoors. This will further strengthen our position to initiate global deployment."
