US energy company Phillips 66 has chosen Australian engineering company Worley to carry out the revamp of its San Francisco refinery to produce renewable fuels.

The project at the facility in Rodeo, California, will reconfigure the refinery and produce up to 2.4bn litres/year (650M gallons/year) of renewable transportation fuels from used cooking oils, fats, greases and vegetable oils.

Worley’s North America West team will carry out the contract with support from the company’s global integrated delivery team.

“As a global company headquartered in Australia, this project aligns with our strategic focus on sustainability and delivering a more sustainable world,” Worley chief executive officer Chris Ashton said.

Phillips 66 is active in the refining, midstream, chemicals and marketing and specialities sectors, according to its website.
