ExxonMobil and Global Clean Energy signed a contract agreeing to purchase 2.5 million barrels (mmbbl) of renewable diesel per annum for the coming five years, according to a press release.

The renewable diesel contract starts from 2022 and will come from a converted California refinery. As per the agreement, the renewable diesel will be sourced from a refinery acquired by Global Clean Energy and produce renewable diesel from Global Clean Energy’s patented varieties of camelina, and other non-petroleum feedstocks. 

Bryan Milton, president of ExxonMobil Fuels and Lubricants Company, said, “Our agreement with Global Clean Energy builds on ExxonMobil’s longstanding efforts to develop and offer products that help meet society’s energy needs while reducing environmental impacts.” 

Some of the non-petroleum feedstocks include: used cooking oil, soybean oil, distillers’ corn oil and other renewable sources will be refined to produce the renewable diesel.

It is estimated that renewable diesels reduce greenhouse emissions by approximately 40% to 80% when compared with petroleum-based diesel.
