Phillips 66 Renewable Diesel, $2.4 B Capex, 1 Next Era Deal, and 3 Partnerships (2025)

Phillips 66 Shifts from Co-processing to Full Conversion for Renewable Diesel Projects

In 2025, Phillips 66 fully committed to a strategy of converting entire refining assets for renewable fuel production, a significant shift from its prior, smaller-scale co-processing activities, to capitalize on market demand and regulatory incentives. This approach leverages existing infrastructure to mitigate the high costs and risks associated with greenfield projects while establishing the company as a major producer in the low-carbon fuels market. The strategy is not limited to production but extends to integrating on-site renewable power and securing dedicated logistics, creating a vertically integrated, lower-carbon value chain.

• Prior to 2025, Phillips 66, like many refiners, engaged in co-processing, blending renewable feedstocks into traditional refining units. In 2025, this evolved with the Rodeo Renewable Energy Complex reaching its full operational capacity of 50, 000 barrels per day (BPD), representing a complete conversion of a legacy fossil fuel asset into a dedicated renewable fuel facility.
• To decarbonize operations at Rodeo, Phillips 66 partnered with Next Era Energy Resources to launch an on-site solar facility generating approximately 60, 000 megawatt-hours per year, directly powering the complex and reducing its carbon intensity and reliance on the grid.
• The company signaled its intent to expand beyond renewable diesel by filing notifications in March 2025 for proposed Sustainable Aviation Fuel (SAF) production at facilities in New Jersey, Texas, and Louisiana, targeting the high-value aviation sector.
• Further diversifying its energy transition strategy, Phillips 66 entered a joint venture with Epsilon Advanced Materials in September 2025 to develop a graphite production facility for the electric vehicle (EV) battery and energy storage markets, indicating a move to capture value in adjacent supply chains.

$2.4 B Capex, Phillips 66 Fuels Midstream Growth and Renewables

Phillips 66’s 2025 capital allocation and acquisitions underscore a dual-track strategy: using cash flow from a strengthened traditional midstream business to fund a focused expansion into renewable fuels. The company’s financial disclosures, including its announced $2.4 billion capital budget for 2026, reveal a disciplined approach that invests in both legacy and emerging energy systems simultaneously, rather than a complete divestment from hydrocarbons.

• On December 15, 2025, Phillips 66 announced its $2.4 billion capital budget for 2026, with a balanced allocation of $1.1 billion toward its refining segment, which now includes its renewable fuels business, and another $1.1 billion to its midstream operations.
• The company fortified its core refining assets by announcing an agreement in September 2025 to acquire the remaining 50% interest in the WRB Refining LP joint venture from Cenovus Energy for $1.4 billion, gaining full ownership and operational control.
• To support its “wellhead-to-market” strategy, Phillips 66 expanded its natural gas liquids (NGL) portfolio by acquiring Pinnacle Midstream in March 2025 and entering a definitive agreement in January 2025 to acquire all equity interests in EPIC Y-Grade GP, LLC.

Phillips 66 3 Key Partnerships Target Solar, Pipelines, and EV Batteries (2025)

In 2025, Phillips 66 executed a series of strategic partnerships to build an integrated ecosystem around its renewable fuels business, addressing critical needs in power supply, product transportation, and market diversification. These collaborations show a sophisticated strategy that extends beyond the refinery gate, aiming to control key logistical and supply chain components to enhance profitability and competitive advantage.

• Renewable Power Supply: In May 2025, Phillips 66 began commercial operations at an on-site solar facility developed with Next Era Energy Resources. This project supplies renewable electricity directly to the Rodeo complex, lowering its operational carbon footprint, which is a critical factor for monetizing credits under low-carbon fuel standards.
• Product Transportation: Phillips 66 partnered with Kinder Morgan, Inc. to advance the Western Gateway Pipeline. After launching a binding open season in October 2025, the companies closed the initial phase in December 2025, moving closer to securing a dedicated, cost-effective channel to transport renewable fuels from Rodeo to key California markets.
• Market Diversification: A September 2025 joint venture with Epsilon Advanced Materials to construct a graphite production facility marks a strategic entry into the EV battery supply chain. This partnership leverages Phillips 66’s expertise in processing carbon materials and provides a foothold in the rapidly growing energy storage market.

California Market Focus, Phillips 66 Aligns Rodeo with State Policy

Phillips 66’s renewable energy strategy in 2025 was geographically centered on California, a decision driven by the state’s lucrative Low Carbon Fuel Standard (LCFS) and advanced regulatory environment. This contrasts with its international decarbonization efforts, which are shaped by different policy mechanisms, and its continued hydrocarbon investments in traditional energy hubs like the Permian Basin.

• The conversion of the Rodeo refinery, development of its on-site solar power, and the proposed Western Gateway Pipeline are all squarely focused on the California market, creating a tightly integrated system designed to maximize value under the state’s specific policy framework.
• The company’s international decarbonization activities are exemplified by the Humber Refinery project in the United Kingdom. This project focuses on abating emissions through a combination of carbon capture and storage (CCS) and the use of low-carbon hydrogen, reflecting a different strategic pathway tailored to European industrial policy.
• Simultaneously, Phillips 66 continued to invest heavily in its traditional midstream business in the Permian Basin through acquisitions like Pinnacle Midstream, demonstrating a strategy of running parallel operations in both emerging and legacy energy markets.

Phillips 66 2026 Outlook, SAF Investment and Western Gateway Pipeline FID

The critical indicator for Phillips 66’s strategy in 2026 will be its willingness to commit capital to a Final Investment Decision (FID) on its proposed Sustainable Aviation Fuel (SAF) projects and the Western Gateway Pipeline. These moves would confirm that the Rodeo conversion was not a one-off project but the first step in a sustained, long-term pivot into a multi-product renewable fuels business with dedicated, proprietary logistics.

• If an FID is announced for SAF production at one of its notified sites, watch for details on capacity and technology. This would signal an aggressive move to capture the premium-priced aviation market and diversify its renewable fuels portfolio beyond diesel.
• If the Western Gateway Pipeline with Kinder Morgan reaches FID, this de-risks the long-term economics of the Rodeo facility by locking in lower-cost, reliable transportation to key end markets, insulating it from third-party pipeline capacity constraints and fees.
• If the Epsilon Advanced Materials joint venture announces a plant location and construction timeline, this validates the seriousness of Phillips 66’s diversification into the energy storage supply chain. Watch for any secured offtake agreements with battery manufacturers as a key signal of commercial viability.
• The deployment of the $2.4 billion 2026 capital budget will be the ultimate tell. A significant allocation within the refining and renewables budget toward new projects, rather than just sustaining existing assets, will confirm the pace and ambition of its energy transition strategy.
