Marathon Petroleum Green Hydrogen Strategy, $1.75 B ONEOK NGL Venture, and $450 M in Refinery Projects (2025)
Green Hydrogen Market Risks and Marathon Petroleum’s Cautious 2025 Stance
In 2025, Marathon Petroleum executed a risk-averse strategy of cautious observation in the green hydrogen sector, prioritizing capital allocation to its core refining and midstream operations rather than pioneering green hydrogen production. This approach stands in contrast to a burgeoning global hydrogen market facing significant volatility, including a 25% contraction in the global project pipeline and a persistent cost disparity where green hydrogen at $4-$12/kg is significantly more expensive than grey hydrogen at $1-$3/kg. Marathon’s actions signal a deliberate choice to fortify its profitable legacy assets while others navigate the high-risk, high-reward environment of early-stage hydrogen development.
- In 2025, Marathon Petroleum directed capital towards modernizing its fossil fuel infrastructure, a marked continuation of its pre-2025 strategy focused on operational efficiency rather than a pivot to new energy vectors. This contrasts with the broader market’s pre-2025 enthusiasm which saw a rapid expansion of project announcements.
- The company’s strategy prioritizes proven, economically viable decarbonization pathways like renewable diesel, which leverage existing refinery infrastructure and benefit from established policy mechanisms. This includes the new 45 Z Clean Fuel Production Credit providing up to $1.00/USG for clean fuels.
- By participating in an industrial coalition with peers like Exxon Mobil and Dow, Marathon Petroleum engages in long-term decarbonization planning, including exploring technologies like hydrogen and carbon capture, without committing to immediate, large-scale capital expenditures.
- This “strategic follower” position maximizes near-term cash flow and shareholder returns but cedes the first-mover advantage in a green hydrogen market projected to grow from $1.5 billion to $125.3 billion by 2035.

$450 M in Upgrades Underscores Marathon Petroleum’s Focus on Core Refining Assets
Marathon Petroleum’s 2025 capital spending plan overwhelmingly reinforces its commitment to its core refining business, allocating hundreds of millions to projects that enhance the efficiency, reliability, and profitability of its existing fossil fuel infrastructure. These investments do not represent a strategic pivot toward green hydrogen production but are instead focused on high-return optimizations of traditional assets. This capital discipline highlights a strategy to maximize returns from its current operational footprint before venturing into more nascent, capital-intensive energy transition projects.
- A planned $200 million spend in 2025 is part of a multi-year, $775 million investment through 2027 for a project, likely a Distillate Hydrotreater (DHT), aimed at enhancing production capabilities within its conventional refining segment.
- The company allocated $150 million in capital for a refinery project in 2025, with an additional $50 million slated for 2026. This investment targets a high-return project with an expected 25% return, focusing on optimizing existing refining assets.
- A $100 million investment was designated for 2025 to modernize and integrate utility systems at the Los Angeles refinery, a move designed to improve energy efficiency and operational reliability, thereby reducing operating costs and incremental emissions.

Marathon Petroleum $1.75 B ONEOK NGL Deal Signals Core Focus (2025)
Marathon Petroleum’s most significant partnership in 2025 is a joint venture with ONEOK focused on natural gas liquids (NGLs), a move that solidifies its market position in traditional midstream energy rather than the green hydrogen economy. This collaboration underscores a strategic priority to invest in large-scale, familiar infrastructure projects that leverage its core competencies and existing market structure. While these assets could potentially be adapted for future hydrogen transport, their immediate purpose is to expand the reach of fossil-fuel-derived products.
- In February 2025, Marathon Petroleum partnered with ONEOK to construct a $1.4 billion NGL export terminal and a $350 million pipeline on the U.S. Gulf Coast, a major investment in traditional energy infrastructure.
- This partnership is squarely focused on enhancing midstream capacity for NGLs, with a targeted completion date of 2028, reinforcing the company’s commitment to its core business lines through the decade.
- This contrasts with its more tentative engagement in low-carbon technologies, such as its participation in a U.S. Department of Energy-backed industrial coalition to explore decarbonization pathways, which involves no firm capital commitments in 2025.

Table: SWOT Analysis for Marathon Petroleum’s Hydrogen Strategy
| SWOT Category | 2021 – 2024 | 2025 – Today | What Changed / Validated |
|---|---|---|---|
| Strengths | Dominant refining and midstream operations with strong, predictable cash flow. | Continued investment in high-return refinery modernization projects (e.g., $450 M in new capex) and midstream expansion ($1.75 B ONEOK JV). | The 2025 strategy validates that the company’s primary strength and focus remain the optimization and expansion of its profitable legacy assets. |
| Weaknesses | Limited public-facing activity or investment in green or blue hydrogen production projects. | No direct capital allocation to hydrogen production projects in 2025; focus remains on renewable diesel and co-processing, which are incremental steps. | The lack of investment in 2025 confirms a persistent weakness: the company is a follower, not a leader, in the hydrogen transition, ceding ground to early movers. |
| Opportunities | Anticipation of federal incentives (like the Inflation Reduction Act) to improve hydrogen project economics. | Finalization of the 45 V Clean Hydrogen Tax Credit (up to $3/kg) and 45 Z Clean Fuel Production Credit creates a concrete financial pathway to integrate clean hydrogen. | The opportunity has crystallized from potential to tangible. The key question is now when, not if, Marathon will act on these powerful incentives for its operations like the Martinez facility. |
| Threats | Competitors announce large-scale green hydrogen projects and form strategic partnerships globally. | Market volatility leads some competitors (e.g., Air Products exiting some US projects) to pull back, but major international projects (NEOM) advance, creating a complex competitive field. | The threat has become more nuanced. While some speculative projects have stalled, validating a cautious approach, well-structured projects are advancing, creating a threat from more disciplined and focused competitors. |
Marathon’s Hydrogen Sourcing Decision for Martinez is the Key 2026 Signal
The most critical indicator of a strategic shift at Marathon Petroleum will be its hydrogen sourcing decision for the Martinez Renewable Fuels project. A commitment to build on-site green or blue hydrogen production, driven by the new 45 V tax credit, would signal a definitive pivot from its current follower strategy. Conversely, a reliance on third-party or grey hydrogen would confirm its intent to remain a cautious integrator, prioritizing operational de-risking over vertical integration into the clean energy supply chain.
- If a Final Investment Decision (FID) for Martinez includes on-site electrolyzers or an SMR with carbon capture, this signals Marathon’s entry as a serious player in clean hydrogen production, leveraging its own offtake demand to de-risk the investment.
- Watch for any announcements of long-term offtake agreements for clean hydrogen from third-party producers, which would be a less capital-intensive but still significant step toward decarbonizing its refining operations.
- These events could be happening as the company’s 2026 capital budget is formulated. A new line item for “low-carbon hydrogen” or “electrolysis projects” would be the clearest financial confirmation of a strategic change.
