Marathon: Phase II of Martinez Conversion on Track to be completed by 2023

Marathon Petroleum Corp. anticipates that the feedstock pretreatment capabilities at its Martinez Renewable Fuels facility in California will be operational in the second half of 2023. With an expected production capacity of 730 million gallons per year by the end of the year, the facility is poised for significant growth.

During the company's second-quarter earnings call on August 1, Marathon officials provided updates on the progress of the Martinez project. Developed in collaboration with Neste, the biorefinery achieved full Phase I production capacity of 260 million gallons per year in the first quarter of 2023. Currently, Phase II activities are underway to install the pretreatment unit and enhance the facility's capacity. Once Phase II is completed, Marathon CEO Mike Hennigan stated that the Martinez facility will rank among the largest and most competitive renewable diesel facilities. He emphasized the facility's competitive operating profile, logistical flexibility, advantageous feedstock slate, and strategic partnership with Neste as key factors contributing to its success.

In addition to the Martinez Renewable Fuels facility, Marathon also operates a renewable diesel project in Dickinson, North Dakota, with a production capacity of 180 million gallons per year. This facility has been operating at full capacity since mid-2021, further bolstering Marathon's presence in the renewable fuels sector.

Marathon Petroleum Corp.'s expansion into renewable fuels underscores its commitment to sustainable energy solutions and aligns with the growing global demand for alternative fuel sources. As the Martinez facility prepares to launch its feedstock pretreatment capabilities and increase production capacity, Marathon is well-positioned to contribute significantly to the biofuel market.
