Phillips 66 Green Hydrogen Strategy, 30 MW Rodeo Solar Project, and Uniper Deal (2024 to 2026)

Phillips 66 ‘Inside-the-Fence’ Strategy: 30 MW Rodeo Solar Project

Phillips 66 is not diversifying into a power utility but is executing a focused “inside-the-fence” strategy, deploying on-site renewable generation to decarbonize its core renewable fuels business, lower product carbon intensity, and reduce operational costs. This approach leverages existing industrial sites to directly address Scope 2 emissions and improve the marketability of its low-carbon fuels, particularly in regulatory-driven markets like California. The strategy avoids the high-risk, capital-intensive entry into the competitive power generation sector by concentrating on optimizing its primary business for the energy transition.

• Between 2021 and 2024, the company’s primary focus was the capital-intensive, multi-billion dollar conversion of its Rodeo, California, facility from a traditional crude oil refinery into one of the world’s largest renewable fuels plants. This period was defined by large-scale asset transformation using established hydrotreating technology.
• The strategy evolved in 2025 with the integration of distributed energy, marked by the commissioning of the 30 MW Rodeo Solar Project. This initiative provides renewable electricity directly to the complex, representing a critical shift from building the asset to optimizing its operational carbon footprint and cost structure.
• This pivot is underscored by the permanent closure of the 139, 000-barrel-per-day Los Angeles refinery in 2025. This move frees up capital and signals a definitive strategic retreat from legacy refining in high-cost, regulatorily complex regions to focus on renewable fuel production.
• Looking ahead, the company is expanding this decarbonization model by exploring green hydrogen integration. A collaboration agreement signed with Uniper in late 2024 to supply the Humber Refinery in the U.K. demonstrates a plan to apply the same principle of using new energy vectors to decarbonize major existing assets.

California vs. UK: Phillips 66 Geographic Focus on Renewables

Phillips 66’s geographic strategy for its energy transition projects is highly concentrated in markets with strong regulatory incentives and clear policy support, primarily California for renewable fuels and the United Kingdom for hydrogen-led refinery decarbonization. Rather than a global shotgun approach, the company is making targeted investments in regions where policy creates durable demand for low-carbon products. This focus allows it to maximize returns on its decarbonization investments and build expertise in navigating complex regulatory environments.

• From 2021 to 2024, the company’s geographic focus was almost exclusively on California. This was dominated by the multi-billion-dollar conversion of the Rodeo refinery, a project directly responsive to the state’s Low Carbon Fuel Standard (LCFS).
• This California focus was reinforced in 2025 with the commissioning of the on-site 30 MW Rodeo Solar project and the SAF supply deal with British Airways for flights originating in the state. This activity is contrasted by the simultaneous closure of the Los Angeles refinery, indicating a strategic refinement within the state to prioritize renewables over legacy assets.
• In 2025, the strategy demonstrated geographic expansion with the Uniper green hydrogen partnership targeting the Humber Refinery in the U.K. This move shows the company replicating its model: using new energy technologies to decarbonize major existing assets in regions with supportive government policies, such as the U.K.’s industrial decarbonization schemes.
• The company’s plan to produce California-specific (CARB) gasoline at its Ferndale, Washington, refinery to supply the California market further illustrates that the state remains the central demand driver shaping its broader West Coast operational strategy.

Renewable Diesel at Scale, Phillips 66 Pilots Hydrogen and Solar

Phillips 66 is executing a tiered technology strategy, operating renewable diesel production at commercial scale while using on-site solar and green hydrogen in early-stage integration phases to systematically de-risk its long-term decarbonization pathway. The company is leveraging mature technology for immediate revenue generation while piloting next-generation solutions that support its core business. This measured approach allows it to build operational expertise in new technologies without making premature, large-scale capital commitments in unproven areas.

• Between 2021 and 2024, the primary technology focus was the commercial-scale deployment of conventional hydrotreating technology to process renewable feedstocks like used cooking oil, fats, and greases. This mature technology was central to the Rodeo conversion project, which reached completion in June 2024.
• In 2025, the technology portfolio expanded into renewable power generation. On-site solar moved from concept to an operational pilot with the commissioning of the 30 MW project at Rodeo. This marks the company’s first major foray into generating its own renewable power to reduce both costs and the carbon intensity of its products.
• Green hydrogen integration remains in an even earlier, collaborative stage. The Uniper agreement is for offtake from a *planned* hydrogen production facility, positioning Phillips 66 as a strategic customer rather than a producer. This approach de-risks its entry into the hydrogen economy by partnering on supply instead of taking on the direct capital risk of production.
• This progression shows a clear strategic logic: using proven, profitable renewable fuel technology as the foundation while layering on supporting decarbonization technologies like solar and hydrogen in a phased, risk-managed manner. Projects like post-combustion capture could follow a similar path.

SWOT Analysis for Phillips 66 Renewable Fuels Strategy

Phillips 66’s strategic pivot to renewable fuels, validated through key operational milestones in 2024 and 2025, effectively leverages its existing infrastructure and deep operational expertise. However, this focused strategy also introduces new dependencies on volatile feedstock markets and an evolving regulatory landscape. The transition mitigates risks associated with legacy refining but creates new exposures in the nascent renewable fuels value chain.

• Strengths have been validated by the successful conversion and ramp-up of the Rodeo facility, proving the company can repurpose legacy assets for large-scale renewable production and enhance their value with on-site renewables.
• Weaknesses are now concentrated in the increased reliance on a single, massive renewable asset and its exposure to the price volatility of renewable feedstocks.
• Opportunities have materialized through the capture of premium market offtake, such as the SAF deal with British Airways, and the establishment of a clear pathway for next-generation decarbonization with the Uniper hydrogen partnership.
• Threats have shifted from construction and conversion risk to operational and market risks, including intense competition for renewable feedstocks and the long-term challenge posed by vehicle electrification.

• If Rodeo consistently operates near its 52, 000 b/d nameplate capacity and captures strong margins through 2026, watch for announcements of new “inside-the-fence” solar or battery storage projects at other Phillips 66 facilities.
• These could be happening: the $2.4 billion capital budget for 2026 provides ample flexibility. If Rodeo’s performance is strong, a portion of this capital will likely be allocated to replicating the Rodeo solar project model. If Rodeo underperforms due to feedstock costs or weak credit values, this capital may be redirected toward more traditional NGL and midstream projects.
• Watch for a definitive investment decision or a binding offtake agreement to emerge from the Uniper collaboration. A firm commitment would signal the Humber green hydrogen project is moving from the exploratory phase to execution, marking a significant step in decarbonizing the company’s European assets.
• Conversely, maintaining high utilization rates (low- to mid-90% range) at its nine remaining traditional refineries in Q 2 2026 signals a pragmatic approach. If renewable fuel margins compress, the company will rely on its optimized legacy fleet to maintain cash flow, potentially slowing the pace of new green investments.
