1U.S. oil companies Exxon Mobil and Chevron are looking to produce more renewable fuels.
2The two largest U.S. oil companies want to produce sustainable fuels without paying the billions of dollars usually needed to change the operations to make the products.
3People with knowledge of the efforts told Reuters the two companies are finding ways to make such products at their existing manufacturing centers.
4Renewable fuels account for 5 percent of U.S. fuel use.
5But that percentage is expected to grow as producers look to cut carbon emissions to fight climate change.
6Both Chevron and Exxon have large refining divisions that add heavily to their carbon emissions.
7The companies have been criticized for being slower to produce renewable energy than European companies, such as Royal Dutch Shell and TotalEnergies.
8The American corporations have spent less money than those companies on green technologies.
9Exxon and Chevron are looking into how to process feedstocks like vegetable oils and partly processed biofuels with petroleum.
10That process produces renewable diesel, sustainable aviation fuel (SAF) and renewable gasoline without greatly raising costs.
11The production of renewable fuels costs more than making regular gasoline without government assistance.
12The sources told Reuters that Exxon is working to understand its ability to process up to 50 percent of some kinds of bio-feedstocks to produce SAF.
13Chevron is also looking into how to put feedstocks through their fluid catalytic crackers (FCC).
14FCCs produce gasoline and are generally the largest part of refining facilities.
15"Our goal is to co-process bio-feedstocks in the FCC by the end of 2021," a Chevron spokesperson told Reuters.
16The bio-feedstocks will supply renewable products to people in Southern California.
17Chevron is working with the U.S. Environmental Protection Agency (EPA) and the California Air Resources Board (CARB) so that the renewable fuel it produces would count toward emission credits.
18Emission credits are financial rewards meant to push companies to emit less pollution.
19The fuel products are still not available for use.
20But the California Energy Commission says that renewable fuel can reduce carbon dioxide pollution by 61 percent to 83 percent.
21Congress is also considering legislation for tax credits that would push oil producers to make sustainable airplane fuel.
22The federal government and some states provide financial incentives to produce renewable fuel.
23Some oil producers, like Texas-based Valero and Finland-based Neste, have increased production of renewable fuels from waste oils and vegetable oils.
24Several other U.S. producers are in the process of partly or fully changing their production plants to make renewable fuels, especially diesel.
25If approved, new ways of producing renewable fuels at refineries could let producers avoid environmental permitting processes, which can take a long time.
26Many of these processes are still going through additional testing.
