b'Partner News Winter 2023 35CorporateCummins approves the use of unblended renewable diesel in all its high-horsepower diesel engines By Thomas J Gill, Max Pearce, Molly G BeatonAs a global front-runner in the engine and power generation industry, Cummins Inc. (NYSE: CMI) is leading the way in powering a more sustainable world. In August 2023, Cummins approved the utilization of unblended renewable diesel throughout their line of high-horsepower diesel engines. But what is unblended renewable diesel and what are the benefits of using it?What is renewable diesel?Renewable diesel, also known as paraffinic fuel, is a low-carbon biofuel produced from processing waste lipids, such as vegetable oils, tallow or used cooking oils. Hydrotreated Vegetable Oil (HVO) is the most popular and readily available paraffinic fuel and is the renewable diesel used by* Exact emissions reduction dependent onHVO not be blended with biodiesel, even if Cummins for testing purposes. feedstock and fuel pathway such blends meet EN15940 standards. Why use renewable diesel? Which products can use renewable diesel?
