US energy company Phillips 66 and Renewable Energy Group, USA, announced plans on 1 November to construct a large renewable diesel plant on the US West Coast.

They aim to use the plant to produce renewable diesel fuel using REG’s BioSynfining technology. Planned feedstocks include waste fats, vegetable oils, animal fats and used cooking oil.

“REG is excited to be working with a leading refiner, Phillips 66, on a project that has the potential to significantly expand biofuel production in Washington State and provide low carbon fuel markets with products that are in significant demand on the West Coast,” said REG CEO Randy Howard. “We look forward to working with state and local stakeholders to facilitate development of this important project and increase the supply of low carbon fuels in the region.”

The new facility’s proposed location would be near Phillips 66’s Ferndale refinery in Washington State because of the convenience of its already existing infrastructure, such as tank storage and access to rail and marine transport.

“The facility’s location in Washington State would enable us to move renewable fuels more efficiently to support West Coast and international fuel market demand,” said Brian Mandell, senior vice president of marketing and commercial for Phillips 66.

The announcement follows more than a year of Phillips 66 working in collaboration with REG on site location and preliminary engineering. The companies expect to make a final investment decision in 2019 and start production at the facility in 2021, if approved.

REG owns 13 biomass-based diesel refineries with a total capacity of 565M gallons/year.
