Ensyn receives key regulatory approvals from CARB

By Ensyn Corp. | February 08, 2016

Barry Freel, chief technology officer of Ensyn Corp., is pleased to announce that Ensyn has been granted key regulatory approvals by California’s Air Resources Board. These approvals relate to the application of Ensyn’s Renewable Fuel Oil as a renewable feedstock for refineries in California for the production of renewable gasoline and diesel (refinery co-processing). The approvals have been granted pursuant to California’s Low Carbon Fuel Standard. Ensyn, Chevron U.S.A. Inc. and Tesoro Corp. were co-applicants in this process.

Ensyn converts forest residues and other non-food biomass to a biocrude known as Renewable Fuel Oil, or RFO, through the application of its proprietary RTP technology. RTP is a fast thermal process that Ensyn has had in commercial use for over 25 years for the production of food products, chemicals and heating fuels. Ensyn is now increasing production capacity for a broader commercialization of its fuels business, including refinery co-processing.

Refinery co-processing involves the processing of RFO in fluid catalytic crackers (FCCs) in refineries alongside traditional FCC fossil feedstocks, resulting in the production of ASTM specification diesel and gasoline. Ensyn has demonstrated this technology in numerous trials and demonstrations, including in operating commercial refineries. Ensyn is commercializing refinery co-processing in alliance with Honeywell UOP, a global leader in technology solutions for the refining industry.

The regulatory approvals received from the ARB covers the production of both gasoline and diesel via RFO co-processing in specific California refineries using RFO produced at Ensyn’s facility in Ontario from forest residues. The carbon intensity of the resulting renewable gasoline and diesel was determined to be in the range of approximately 20-25 g CO2e/MJ, or approximately 70 percent less than traditional petroleum-based fuels. Ensyn expects that RFO produced at locations closer to the refineries will have reduced carbon intensity due to lower transportation impacts.

CJ Warner, executive vice president of strategy and business development at Tesoro, said, “We are very pleased to see these regulatory pathways confirmed. These approvals help support and validate our plans to process these renewable feedstocks using our existing infrastructure to produce less carbon-intensive fuels and help lower the cost of compliance with LCFS requirements in California.”

Veronica May, vice president and general manager of Honeywell UOP’s renewable energy and chemicals business, said, “We congratulate Ensyn, Chevron and Tesoro on securing these regulatory pathways. We believe refinery co-processing offers refiners a cost-effective and efficient option for integration of cellulosic feedstocks into their operations.”
