Marathon Petroleum CCUS Strategy, $1.75 B ONEOK Joint Venture, $300 M in Refinery Upgrades, and 3 Projects (2021-2025)

CCUS Adoption, Marathon Petroleum Infrastructure-First Strategy

In 2025, Marathon Petroleum diverged from peers by prioritizing foundational infrastructure investments over direct carbon capture projects, a strategy that builds long-term capability while avoiding the near-term technological and financial risks of first-mover CCUS deployment.

• Prior to 2025, Marathon Petroleum’s decarbonization efforts were framed by broad goals to reduce emissions intensity, a common posture across the industry that lacked specific, large-scale project commitments.
• The strategic shift in 2025 is marked by the $1.75 billion joint venture with ONEOK to build Gulf Coast export infrastructure, a move that strengthens core logistics rather than directly abating emissions from its facilities.
• This contrasts with competitors like Occidental Petroleum, which is committing $1.3 billion to its STRATOS Direct Air Capture facility, targeting a late 2025 launch to remove 500, 000 metric tons of CO 2 annually.
• By focusing on refinery modernization and midstream expansion, Marathon Petroleum is preparing its asset base for future CCUS integration, positioning itself as a fast-follower rather than a technology pioneer.

$1.25 B in 2025 Spending, Marathon Petroleum Prioritizes High-Return Projects

Marathon Petroleum’s 2025 capital plan allocates $1.25 billion to projects that improve operational efficiency and returns, with specific investments in refinery upgrades demonstrating a preference for tangible, near-term value over speculative ventures into large-scale carbon capture.

• The company committed $100 million in 2025 to modernize the utility systems at its Los Angeles refinery, a project expected to yield a 20% return through improved energy efficiency and enhanced reliability.
• A significant multi-year project at the Galveston Bay refinery received a $200 million allocation for 2025 as part of a larger investment to develop a high-pressure distillate hydrotreater.
• These investments directly reduce the carbon intensity of operations, with existing efficiency initiatives already delivering over 45, 000 tonnes of annual CO 2-equivalent reductions and $5 million in cost savings.

Marathon Petroleum 2 Strategic JVs, ONEOK and Neste (2025)

Strategic joint ventures in 2025 are central to Marathon Petroleum’s strategy, enabling the company to leverage partner expertise and share capital risk in large-scale infrastructure projects for both fossil fuel logistics and renewable fuel production.

• The most significant partnership is the joint venture with ONEOK, announced in February 2025, to construct a $1.4 billion NGL export terminal and a $350 million pipeline on the U.S. Gulf Coast.
• This collaboration combines Marathon Petroleum’s production and marketing scale with ONEOK’s midstream processing and transport capabilities to expand global market access.
• In March 2025, the company finalized a joint venture with Neste for the Martinez renewable fuels project, converting a traditional refinery to produce renewable diesel and advancing its lower-carbon product offerings.

U.S. Gulf Coast, Marathon Petroleum Focus on Strategic Hub for CCUS

Marathon Petroleum’s 2025 investments are heavily concentrated in the U.S. Gulf Coast, a region selected for its existing energy infrastructure, export access, and geological suitability for future carbon sequestration activities.

• Before 2025, capital was spread more broadly across the company’s refining portfolio. The 2025 strategy consolidates major growth capital in the Gulf Coast.
• The $1.75 billion ONEOK joint venture is entirely focused on this region, building new pipeline and export terminal assets to connect Permian Basin supply with global markets.
• The Gulf Coast is not only a major hub for oil and gas logistics but is also emerging as the epicenter for the U.S. CCUS industry, with numerous projects planned to take advantage of favorable geology for CO 2 storage.
• By reinforcing its infrastructure in this area, Marathon Petroleum is creating a strategic footprint that can support both its current business and future large-scale CCUS projects that rely on pipeline transport for CO 2.

Proven vs. Emerging Tech, Marathon Petroleum’s De-Risked CCUS Approach

In 2025, Marathon Petroleum is deliberately deploying mature, commercially proven technologies to enhance operational efficiency, while the broader industry sees competitors push emerging technologies like Direct Air Capture to commercial scale.

• The company’s key 2025 projects, such as utility system modernizations and the development of high-pressure distillate hydrotreaters, utilize well-established engineering solutions with predictable returns and low technological risk.
• This contrasts with the period before 2025, where CCUS was largely in the R&D and pilot phase for most operators. By 2025, technologies like post-combustion capture have reached a Technology Readiness Level (TRL) of 9, meaning they are fully commercialized.
• While Marathon Petroleum observes these developments, competitors like Occidental Petroleum are validating the commercial viability of DAC with the launch of the STRATOS facility, taking on the risks of being a first-mover.
• This positions Marathon Petroleum to adopt proven CCUS technologies once costs are further reduced and operational best practices are established by the industry’s early adopters.

SWOT Analysis, Marathon Petroleum CCUS Strengths and Laggard Risks

Marathon Petroleum’s infrastructure-first strategy provides significant financial strength and operational stability but creates a potential long-term weakness by delaying direct engagement with carbon capture technologies, risking a competitive disadvantage as the market matures.

• The company’s strength lies in its financially prudent, risk-averse approach that generates immediate shareholder value through high-return, efficiency-focused projects.
• A key weakness is the lack of direct experience in developing and operating large-scale CCUS facilities, creating a knowledge gap compared to first-mover competitors.
• The primary opportunity is the ability to become a “fast-follower, ” deploying de-risked and more cost-effective CCUS technology on its modernized infrastructure when the market is more developed.
• The main threat is that competitors establish a significant technological and operational lead, while regulatory shifts could penalize companies without active CCUS projects sooner than anticipated.

What to Watch, Marathon Petroleum’s Pivot from Infrastructure to CCUS

The critical indicator for Marathon Petroleum’s strategy moving beyond 2025 will be the first concrete capital commitment to a commercial-scale carbon capture project at one of its major refining assets.

• If Marathon Petroleum announces a pilot or full-scale CCUS project at its Galveston Bay refinery, it would signal a major pivot from preparation to implementation, leveraging the new infrastructure built with ONEOK.
• Watch how the company allocates its planned $575 million capital spend for 2026-2027; a significant portion directed toward a capture facility would validate a shift in strategy.
• A failure to announce any direct CCUS project by 2026 could indicate that the company believes the technology or economics are not yet favorable, reinforcing its conservative, fast-follower stance and potentially ceding more ground to first-movers.
• Further guidance from the U.S. Treasury on the 45 Q tax credit could alter the financial models and either accelerate or delay Marathon Petroleum’s decision to invest directly in CCUS.
