Joule Achieves U.S. EPA Registration for CO2-Recycled Ethanol

Bedford, Mass

Joule, the pioneer of liquid fuels from recycled CO2, today announced that its fuel grade Sunflow®-E ethanol has been registered by the U.S. Environmental Protection Agency (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. 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,” said Serge Tchuruk, President and CEO of Joule.

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. 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,” said Mr. Tchuruk.

About Joule  
Joule has pioneered a CO2-to-fuel production platform, effectively reversing combustion through the use of solar energy. The company’s platform applies engineered catalysts to continuously convert waste CO2 directly into renewable fuels such as ethanol or hydrocarbons for diesel, jet fuel and gasoline. Free of feedstock constraints and complex processing, Joule’s process can achieve unrivaled scalability, volumes and costs without the use of any agricultural land, fresh water or crops. Joule is privately held and has raised over $200 million in funding to date, led by Flagship Ventures. The company operates from Bedford, Massachusetts and The Hague, The Netherlands with production operations in Hobbs, New Mexico. Additional information is available at
