Accelerating the world’s paths to net zero by building a new business with new markets 

The world currently generates about 34 billion metric tons of energy-related CO2 emissions per year. Industrial activity, power generation, and commercial transportation together account for ~80% of those emissions.1

Emission-reduction markets in these hard-to-decarbonize sectors potentially represent a $6 trillion opportunity by 2050.2

This provides significant opportunities for our Low Carbon Solutions business, where we’re working to establish a competitively advantaged foundation that secures a leading position in these new markets.

Our work involves technologies to capture, transport, and store molecules; produce hydrogen from other molecules; and source and co-process lower-carbon-intensity molecules. All of these technologies align with the competitive advantages we’ve built in our traditional businesses. 

We understand our role and the unique and important contributions we can make. Our customers, many governments, and strategic partners see how our experience, skills, and capabilities can meaningfully help reduce emissions for ourselves and others. 

Our ability to manage molecules aligns with our core competencies in the low-carbon space. We have the necessary scale and infrastructure to bring these technologies to market, spurring innovation and reducing the cost of GHG emissions reduction.

These technologies can be developed and deployed in three main phases:

  • Early phase: We are working with today’s policies, technology, and infrastructure to build foundational projects, and we’re making real progress. In this phase, we’re working to demonstrate their potential as attractive investments and as lower-emissions solutions. 
  • Growth phase: This phase will be shaped by additional policy that helps develop market-based solutions that make decarbonization affordable. It is also defined by cost reductions through deployment of new and existing technology. In this phase, we can leverage the breadth of our operations to develop economies of scale. 
  • Maturity phase: This represents the full transition to market forces. Progress will be bolstered by additional cost reductions through a continued focus on scaling new technology and the reuse of infrastructure.  

Government policy can play a key role in building new markets, especially in the near term. Rational and constructive policies are needed to drive projects in the early stages. We have the expertise and network to bring this technology to the market.

We support legislation like the U.S. Inflation Reduction Act (IRA), which provides incentives for companies to be part of the solution. European policy is currently more prescriptive and limits solutions for hard-to-decarbonize sectors. At this early stage, constructive policy remains critical to enable emissions reductions, advance technology, and drive scale to lower costs. Ultimately, to achieve society’s net-zero ambitions, competitive markets for emissions reduction will need to develop.

We support a policy and regulatory framework for carbon capture and storage that would:

  • Sustain long-term government support for research and development.
  • Provide standards to ensure safe and secure CO2 storage.
  • Allow for fit-for-purpose CO2 injection well design standards.
  • Provide legal certainty for geologic storage ownership.
  • Ensure a streamlined permitting process for carbon capture and storage facilities.
  • Enable interstate CO2 pipeline expansion.
  • Provide access to CO2 storage capacity owned or controlled by governments.
  • Help develop carbon credits based on life cycle analysis of carbon-removal projects.

Investing in a lower-emission future

We’re pursuing up to $30 billion in lower-emission investments from 2025 through 2030, with about 65% directed toward reducing the emissions of other companies.6

Carbon capture and storage

What it is

Carbon capture and storage is just what the term implies. Once CO2 is captured at factories or power plants, it is transported and injected it into geologic formations thousands of feet below the earth’s surface for safe and secure storage. The CO2 is held in place by thick, impermeable-seal rocks. 

Carbon capture and storage, on its own or combined with hydrogen production, is one of the few proven technologies that could drive significant CO2 emission reductions from high-emitting and hard-to-decarbonize sectors. These include power generation, refining, steel, cement, and chemicals manufacturing. According to the Center for Climate and Energy Solutions, carbon capture and storage can capture more than 90% of CO2 emissions from power plants and industrial facilities.7

What respected third parties are saying about carbon capture and storage

Both the International Energy Agency (IEA) and the United Nations Intergovernmental Panel on Climate Change (IPCC) see carbon capture and storage as key to reaching global emissions goals.

The IEA NZE report concludes that more than 6 billion metric tons per year of CO₂ will need to be captured and stored by 2050 to reach a net-zero future.8  By comparison, the world’s current capture capacity is far below that at about 40 million metric tons of CO₂ per year.9 The agency has also said “reaching net zero will be virtually impossible” without carbon capture and storage.10

The IPCC estimates that the cost of achieving a 2°C outcome would more than double without carbon capture and storage.11

Image Growth of lower-carbon solutions between 2020 and 2050 in IPCC Likely 2°C scenarios12

We identify opportunities with concentrated streams of CO2 near sites with safe and secure storage space, and where we can use existing infrastructure to gain scale to offer cost-effective solutions to customers.

Leading now

We have the only large-scale end-to-end carbon capture and storage system in the world.13  With more than 1,300 miles of pipeline and more than 30 years of experience in carbon capture, we lead the industry in the successful deployment of this technology at scale. We are continuing to develop and expand our capacity for storing CO2 on a long-term basis. 

Our initial CCS activity is focused on the U.S. Gulf Coast. This region has the critical drivers needed to provide a lower-cost decarbonization solution for industrial applications: a high concentration of emitters, geologic storage space, and existing transportation infrastructure. These drivers, strengthened by policy like the IRA, are helping us build a carbon capture and storage network that will help our industrial customers significantly reduce their emissions. 

The U.S. Gulf Coast has a large concentration of CO2 emissions – one third of all U.S. industrial emissions come from this region.14

This makes it a great strategic fit as about 70% of our CCS pipelines are located in the Gulf Coast states of Louisiana, Texas, and Mississippi. Our network will connect multiple CO2 emitters with CO2 storage locations that will improve operations reliability. This transport and storage network supports multiple low-carbon businesses – including carbon capture and storage, hydrogen, ammonia, and biofuels.

We continue to add suitable acreage onshore and offshore to expand our storage capacity, with 30 Mta per year expected by 2030.15  Building on our successful collaborations with host governments, we are also negotiating to gain access to nationally owned acreage that holds potential for CO₂ storage. We also continue to work with local jurisdictions on the appropriate permitting to store CO2, which will be essential to the success of these projects. We recently secured the largest offshore CO2 lease in the United States from the Texas General Land Office. With over 271,000 acres, the site is our newest asset on the U.S. Gulf Coast.

Another vital element of establishing a successful business is building a customer base, and we’re making great progress. Our customers include a major fertilizer company, an industrial gas producer, a leading steel manufacturer, and more: 

  • CF Industries: A leading global manufacturer of hydrogen and nitrogen products. They signed the largest-of-its-kind commercial agreement with us to capture and permanently store up to 2.5 million metric tons of CO2 emissions annually from their manufacturing complexes in Louisiana and Mississippi. 
  • Linde: One of the world's leading industrial gases and engineering companies. They entered into a long-term commercial agreement with us in which we plan to transport and permanently store up to 2.2 million metric tons of CO2 annually from Linde's new clean hydrogen production facility in Beaumont, Texas.
  • Nucor Corp: North America’s largest steel and steel products producer. They entered into a long-term commercial agreement with us where we will capture, transport, and store up to 800,000 metric tons of CO2 annually from their manufacturing site in Convent, Louisiana. 
  • New Generation Gas Gathering (NG3): The first natural gas customer to use our CCS infrastructure. We have joined forces with the NG3 project to capture and store up to 1.2 million metric tons of carbon dioxide annually from their Louisiana facility.
  • Calpine Corporation: The nation’s largest producer of electricity from natural gas. In April 2025, they entered into an agreement with us to transport and permanently store up to 2 million metric tons of CO2 annually from Calpine’s Baytown Energy Center, a cogeneration facility near Houston, Texas.

What’s next

  • Building our customer base: We continue to work with others in the industry to spur advances in technology to lower cost and further build our customer base. We see potential to reduce CO2 emissions across the Gulf Coast by more than 100 million metric tons per year.17
  • Policy advocacy: Land access is critical to accelerating carbon capture project deployment – onshore and offshore. We continue to advocate for streamlined permitting and regulation for long-term CO2 storage.
  • Studying storage: We are working with leading universities and other research organizations to advance knowledge in monitoring requirements and modeling of geologic storage. This work includes seal characterization for containment assessment,18 as well as optimal long-term monitoring of stored CO₂. 

Hydrogen

What it is

When used for energy, hydrogen does not emit carbon, and it can generate the high temperatures needed to produce steel, cement, and refining and chemical products without carbon dioxide emissions. This means it could serve as an affordable and reliable source of energy for hard-to-decarbonize industrial processes.

What respected third parties are saying about hydrogen

In 2024, the National Petroleum Council (NPC) published “Harnessing Hydrogen: A key element for the U.S. Energy Future.” The study details deployment of low-carbon-intensity hydrogen at scale in the United States. 

The NPC assembled a diverse team of more than 300 experts from over 100 organizations, 70% of which come from outside of the oil and natural gas industry. This study applied scenario-based modeling, partnering with Massachusetts Institute of Technology (MIT) Energy Initiative. 

The key finding? Deploying lower-carbon hydrogen at scale in hard-to-abate sectors in the United States can lower the cost of reducing carbon emissions. In fact, under the MIT’s Net Zero by 2050 scenario, closely modeled on IEA’s NZE, achieving net zero would cost approximately 30% more without hydrogen.19

Leading now

Just as we have a long history with carbon capture and storage, we have deep and broad experience with hydrogen. We use hydrogen in just about every one of our refining and chemical plants, and we’re looking to expand its use further.  

In Baytown, Texas, we are working to develop the world’s largest low-carbon hydrogen production facility. This project is being designed to produce 1 billion standard cubic feet of hydrogen per day.21 The plan will also produce around 1 million metric tons of low-carbon ammonia per year. 

The Baytown facility's access to the certified lower-emission natural gas we produce in the Permian Basin and nearby CCS and hydrogen infrastructure are key advantages. Industry peers and major players have recognized this and joined the project: 

  • Air Liquide: Air Liquide's project centers around building, owning, and operating four Large Modular Air separation units (LMAs) to produce and supply 9,000 metric tons of oxygen and up to 6,500 metric tons of nitrogen daily to the facility.  The agreement would leverage Air Liquide’s existing pipeline infrastructure to foster the development of low-carbon hydrogen.
  • ADNOC: ADNOC entered the Baytown project with a 35% equity stake. This investment will support both companies’ net-zero ambitions, accelerate decarbonization of hard-to-abate sectors, and meet rising demand for low-carbon hydrogen and ammonia.

We’re getting our foundational project in Baytown ready, but we need the right policy and necessary regulatory permits to make it a reality. Our Baytown project meets nearly 10% of the U.S. Department of Energy Hydrogen Program Plan’s projected 10 million metric tons of hydrogen per year by 2030.22 We expect to capture and store approximately 98% of the CO2, or about 7.5 million metric tons per year, associated with producing this hydrogen.23  The new plant could supply Gulf Coast industrial customers, as well as our own facilities in the Baytown area, with clean-burning hydrogen fuel for process operations. Front-end engineering is underway.  

What’s next

  • Policy advocacy: Advocate for policies that advance hydrogen and ammonia projects, as well as broader policies that create a market for carbon abatement.
  • Research and development: We are working with universities to expand understanding of the end-to-end carbon emissions from different technologies, including hydrogen. For example, the life-cycle tool we helped to develop as part of the MIT Energy Initiative is being used by policymakers and others as they consider policies to reduce global emissions at the lowest cost to society.24

Lower-emission fuels

What they are

These fuels generate fewer GHG emissions over their life-cycle than the traditional fuels they replace. They include biofuels made from renewable sources like plants and waste, biomass and synthetics made from hydrogen, and captured CO2 to form methanol. Lower-emission fuels have the high energy density required to move heavy trucks, airplanes, trains, and ships. Renewable diesel may reduce life-cycle carbon emissions by up to 80% compared to conventional diesel.25 Demand for these fuels is expected to grow rapidly. Our Global Outlook projects the global transportation sector will use nearly 9 million barrels of biofuels per day by 2050, more than four times 2021 levels.26

Our Product Solutions business is working to grow lower-emission fuels by applying technology and infrastructure. At the same time, our Low Carbon Solutions business is working to develop lower-emission fuels, underpinned by our other low-carbon businesses. 

We’re exploring the combination of biomass-based fuel production with carbon capture and storage. This opportunity could open the door to very low- or negative-carbon intensity fuel production. Low-emission fuels can utilize existing distribution infrastructure, lowering the cost of deployment.  

We’re also looking at how we can efficiently transform natural gas into methanol-based fuels. And, we already have the capability to convert methanol to multiple end-use fuels, such as marine and jet fuel. This ability could enable a range of lower-emission fuels. 

Leading now

  • Canada: We are building renewable diesel facilities at our majority-owned affiliate Imperial Oil’s Strathcona refinery. The facility is expected to be the largest of its kind in Canada and capable of producing up to 20,000 barrels a day.
  • France: Our affiliate Esso France began producing SAF in November 2023. We’re targeting production of more than 3,000 barrels per day of biofuels – including sustainable aviation fuel – at the Gravenchon facility in 2025. 

What’s next

  • Co-processing: Critically needed to expand the production of biofuels, co-processing is the ability to process biofeed and conventional feedstock together. Where policy allows, we are conducting co-processing trials in our facilities to produce lower-emission fuels, including SAF. With constructive policy, co-processing would enable faster, lower-cost delivery of these fuels to customers versus constructing new facilities.
  • Maritime goals: We support the International Maritime Organization’s GHG emission-reduction goals, and we are working to help our customers determine the best ways to meet them. For example, we have supplied ExxonMobil bio marine fuel oil blends in Singapore and Amsterdam-Rotterdam-Antwerp bunkering hubs. 
  • Testing with Toyota: Toyota and ExxonMobil recently conducted public road tests using our innovative lower-GHG-emission fuels in Toyota’s advanced engines and vehicles. So far, the program has demonstrated that these research fuels can be compatible with today’s vehicles and have the potential to use existing infrastructure. 
  • New jet fuel technology: We announced a new technology that can produce jet fuel using renewable methanol as the feedstock.27 This renewable methanol has a lower carbon intensity and can be derived from processes that use biofeeds (e.g., wood waste) or low-carbon hydrogen. We expect this process to provide a higher yield of jet fuel than other techniques, using feeds derived from gasification and captured CO2 and hydrogen, which has the additional potential to be used to make other fuels or chemicals.

Lithium

What it is

Lithium is a key component of battery technology. Batteries account for over 80% of global lithium use, and EVs rely on lithium for their rechargeable batteries. EVs can play a key role in reducing emissions in transportation, and lithium demand is expected to triple by 2030.28

Leading now

In 2023, we announced plans to produce lithium carbonate for use in EV battery manufacturing by employing direct lithium extraction (DLE) technology in southern Arkansas. By applying technology to separate the lithium from deep brine reservoirs, we’re working to produce this critical mineral more efficiently and with fewer environmental impacts than traditional hard rock mining. We believe our existing skills in subsurface exploration, drilling, refining, and chemicals will allow us to bring meaningful scale to this technology and provide auto battery manufacturers with a more reliable, lower-carbon lithium supply option.29

Other solutions

Expanding our advantage through integrated value chains

Image Expanding our advantage through integrated value chains

Carbon capture and storage, hydrogen, lower-emission fuels, and lithium are far from the only emission-reduction technologies in the world. We are always looking for opportunities that fit our strengths, capabilities, and businesses.

For example, many of our natural gas and LNG customers have significant post-combustion emissions that they’d like to reduce. We offer a “one-stop shop” for CO2 capture, transportation, and storage that will help these customers reduce their emissions. 

We also see a growing opportunity in the market for carbon materials to become a large domestic supplier of yet another key component of electric vehicles. Synthetic graphite in EV batteries can potentially provide up to a 30% improvement in range, as well as faster charges.

We’re building on our technology, scale, project execution, and integration advantages to establish an attractive new business. We believe this new business complements our traditional businesses and will underpin the company’s growth and returns for decades to come.
