Biodiesel and the X15: Low-carbon power for 2027 and beyond
For nearly 20 years, biodiesel has been approved by Cummins for use in its on-highway diesel engines.
Cummins’ iconic workhorse, the X15 diesel, is approved to run up to B20 which contains up to 20% biodiesel mostly obtained from soybeans. Fleets and owner-operators using biodiesel in the X15 have long-enjoyed greater lubricity, lower emissions and higher cetane values over conventional diesel.
A low carbon fuel like biodiesel will get even better when paired with Cummins’ new 2027 X15.
“I’m excited now more than ever to hear and get feedback from the industry,” Clean Fuels Alliance America Technical Director Scott Fenwick said of the latest advanced diesel engines like the Cummins 2027 X15 which meet EPA 2027 emissions regulations.
Fenwick noted that companies remain dedicated to lowering their emissions regardless of regulatory direction. Pepsi and ADM recently announced their commitment to testing B99 supplied by Pilot, the first station in the U.S. to provide nearly pure biodiesel. Trucks will be equipped with Optimus fuel systems that enable B100 use.
