Which company is leading in carbon capture?

There isn’t one company that leads every part of carbon capture. The leaders depend on whether you mean capturing CO₂ directly from industrial facilities, removing it from the atmosphere, or transporting and storing it underground.

If you're looking at this as an investment opportunity or trying to identify the most important companies in the industry, I'd separate the market into three groups: established industrial players, emerging direct-air-capture companies, and companies building carbon-storage infrastructure.

The leading carbon capture companies

1. ExxonMobil

Best overall for established CCS

A leading contender in conventional carbon capture and storage, with extensive CO₂ transport and underground storage infrastructure. ExxonMobil reports that it has cumulatively captured more CO₂ than any other company, at 120 million metric tons. Carbon capture and storage

2. Occidental Petroleum

A major contender in direct air capture through its subsidiary 1PointFive. Its STRATOS facility in Texas is designed to capture up to 500,000 metric tons of CO₂ annually at full capacity. Actual output during ramp-up may be much lower. 1PointFive and Bain & Company Announce Agreement for…Global Direct Air Capture Market Size & Forecast

3. SLB

A major technology and services provider for industrial carbon capture. Its SLB Capturi business combines capture technology with engineering and project delivery, with projects targeting industries such as cement and power generation.

4. Climeworks

One of the best-known pioneers of direct air capture, which removes CO₂ already present in the atmosphere rather than capturing concentrated emissions from a factory. Its technology is commercially deployed, but scaling it economically remains a challenge. High-quality carbon removal companyLargest operational CCS projects globally 2025

My assessment:

• Most established carbon capture infrastructure: ExxonMobil.
• Most ambitious large-scale direct-air-capture bet among public companies: Occidental through 1PointFive.
• Industrial capture technology and engineering: SLB.
• Specialist direct-air-capture pioneer: Climeworks.

One important distinction: capturing CO₂ from a concentrated industrial exhaust is generally easier and cheaper than extracting it from ordinary air. These are related but different markets.

Are you asking from an investment perspective?

If so, I'd focus first on XOM, OXY, and SLB. They offer different ways to participate in the sector, but their stock performance also depends on their broader oil-and-gas businesses, capital spending, regulation, and whether carbon capture projects become profitable.

I can compare these three on growth potential, valuation, carbon-capture revenue exposure, and risk to identify which looks most promising as an investment.

When evaluating who is "leading" in carbon capture and storage (CCSS) or carbon dioxide removal (CDR), leadership is typically split into different categories depending on whether you are looking at large-scale industrial infrastructure, direct air capture (DAC), technology providers, or energy majors.

The primary leaders in the carbon capture space are categorized below by their domain:

1. Energy Majors & Infrastructure Leaders (Point-Source & Transport)

These energy giants are leading in large-scale deployment, pipeline networks, and capital integration, transforming carbon capture from a compliance tool into an operational business.

• ExxonMobil (NYSE: XOM): Widely considered a major infrastructure leader, especially after its acquisition of Denbury, giving it the largest operational carbon dioxide pipeline network in the United States. It handles major industrial point-source capture deals along the U.S. Gulf Coast. Top Carbon Capture Stocks for 2027: The Money Is Underground

• Occidental Petroleum (NYSE: OXY): A dominant force through its 1PointFive subsidiary, heavily scaling both industrial capture and massive Direct Air Capture (DAC) infrastructure (such as the Stratos project). 6 energy companies investing most in carbon capture

• Equinor (NYSE: EQNR): A pioneer in offshore carbon storage, leading European efforts with landmark cross-border storage projects like Northern Lights in Norway. 6 energy companies investing most in carbon capture

2. Direct Air Capture (DAC) Pioneers

Direct air capture removes CO2 directly from the ambient atmosphere rather than a smokestack.

• Climeworks: Based in Switzerland, Climeworks is a global bellwether for solid-sorbent direct air capture, operating major facilities like the Mammoth and Orca plants in Iceland. Top 10 Leading Carbon Capture Companies in 2026 - Carbelim

• 1PointFive / Carbon Engineering: Utilizing captured technology originally developed by Carbon Engineering, 1PointFive is building out some of the world's largest commercial DAC facilities.

• Heirloom Carbon: An American innovator using a unique, accelerated limestone-based process to permanently remove atmospheric carbon. Top 10 Leading Carbon Capture Companies in 2026 - Carbelim

3. Industrial Technology & Equipment Providers

These companies supply modular capture technology and solvent-based systems to heavy emitters like cement, steel, and power plants.

• Mitsubishi Heavy Industries (MHI): Exceptionally experienced in solvent-based post-combustion capture for large industrial facilities globally. Top 10 Leading Carbon Capture Companies in 2026 - Carbelim

• SLB Capturi: A prominent player formed via joint efforts (including SLB/Schlumberger) delivering modular and large-scale industrial capture solutions.

• Carbon Clean & Svante: Both are widely recognized for developing compact, solid-sorbent filters and modular technology tailored to retrofit existing industrial plants.

Are you looking at carbon capture from an investment perspective, or are you researching specific technologies (like direct air capture vs. industrial point-source reduction)?

Because "carbon capture" spans different approaches - such as industrial point-source capture (capturing emissions from factories/power plants) versus direct air capture (pulling CO2 straight from the atmosphere) - leadership depends heavily on the category:

• • Industrial Point-Source & Market Share Leader: Mitsubishi Heavy Industries (MHI) is widely considered the market-share leader in traditional industrial carbon capture. They have deployed numerous large-scale post-combustion capture plants globally using their proprietary KM CDR process. Other legacy engineering and energy heavyweights like Fluor Corporation and Shell also hold major market positions. Top 10 Leading Carbon Capture Companies in 2026 - Carbelim

• Oil & Gas / Sequestration Heavyweight: ExxonMobil claims the title of sequestering and capturing more cumulative industrial

than almost any other commercial entity, backed by multi-billion-dollar investments in industrial hubs. Meanwhile, Occidental Petroleum has taken a massive industry footprint by acquiring major direct-air-capture firm Carbon Engineering to build out massive hub infrastructure.

• Direct Air Capture (DAC) Pioneer: Climeworks (based in Switzerland) is the most prominent and high-profile pioneer specializing strictly in modular, geothermal-powered direct air capture facilities (such as their plants in Iceland).

If you're looking into a specific angle, let me know:

• Are you interested in Direct Air Capture (DAC) startups or heavy industrial/factory capture?
• Are you looking from an investment/stock perspective or a technology comparison?

There isn’t one clear leader across all carbon capture: Climeworks is a prominent direct-air-capture company, while SLB Capturi and ExxonMobil are major players in industrial capture and large-scale storage infrastructure.(carboncredits.com)(energy-oil-gas.com)

🌍 Key Players in Carbon Capture (2026)

🔑 Insights

• Climeworks is the most credible operator today, with real-world capture at scale, though actual tonnage is still modest compared to targets.

• 1PointFive has the largest ambitions and strongest customer commitments but remains unproven until its facilities deliver verified capture.

• SLB Capturi is a leader in industrial CCS, already running one of the world’s largest cement capture projects.

• Heirloom and Carbon Clean represent innovative approaches - mineralization and modular point-source capture - that could complement DAC at scale.

⚠️ Challenges & Risks

• Cost remains high: Deals in 2026 show prices ranging from ~$444/tonne (CarbonCapture Inc.) to ~$989/tonne (Heirloom), far above long-term targets of <$100/tonne.Top 7 Direct Air Capture Companies in 2026

• Scaling gap: Announced capacities often exceed actual delivered tonnes, raising concerns about overpromising.

• Policy uncertainty: U.S. federal support has become less reliable, with cancellations of clean-energy awards in 2025.Top 7 Direct Air Capture Companies in 2026
