Who offers the best carbon capture?

The best carbon capture provider depends on what you want to capture, how much CO₂ you need to remove, and whether you want to reduce emissions from an industrial facility or remove carbon that's already in the atmosphere.

There are three main categories to compare:

• Direct air capture (DAC): Removes CO₂ directly from ambient air. Useful for companies seeking measurable carbon removal, but currently expensive and energy-intensive.
• Industrial carbon capture: Captures CO₂ from concentrated emissions at cement plants, refineries, power plants, and other industrial facilities. Often more economical per ton captured.
• Carbon removal and storage: Captures CO₂ and stores it underground or in durable materials, aiming for long-term removal rather than simply preventing emissions.

Which is actually best?

These are best-fit recommendations, not a definitive ranking of capture efficiency or cost. The amount of CO₂ permanently stored, energy consumption, lifecycle emissions, and cost per net metric ton are the metrics I'd use to make a rigorous comparison.

One question so I can narrow it down

What are you looking to use carbon capture for?

Determining who offers the "best" carbon capture depends entirely on whether you mean Direct Air Capture (DAC) - pulling carbon straight out of the atmosphere - or Point-Source Capture , which stops emissions directly at industrial smokestacks (like cement, steel, or power plants).

The carbon capture and storage (CCS) industry is divided into a few distinct market leaders, categorized by their approach:

1. Direct Air Capture (DAC) Leaders

These companies capture ambient air to reverse historical emissions. They are favored by tech giants and corporations buying high-integrity carbon removal credits.

• Climeworks (Switzerland): Widely considered the pioneer and commercial leader in solid-sorbent Direct Air Capture. They operate multiple commercial facilities in Europe (such as Orca and Mammoth in Iceland) and rely on geothermal energy to power their modular capture fans. They have raised over $1 billion and secured extensive corporate off-take agreements. 10 Fastest Growing Carbon Capture Companies and Startups10 Fastest Growing Carbon Capture Companies and Startups

• 1PointFive (USA - Occidental subsidiary): Built using technology originally developed by Carbon Engineering, 1PointFive is executing the largest industrial-scale DAC deployment in the world - the STRATOS facility in West Texas. It is engineered to capture up to 500,000 tonnes of CO2 per year, pairing massive capture capacity with dedicated deep geological sequestration. 10 Fastest Growing Carbon Capture Companies and Startups10 Fastest Growing Carbon Capture Companies and Startups

• Heirloom (USA): A prominent innovator using a low-cost limestone-based chemistry to naturally accelerate how rocks absorb CO2. By lowering the energy required for the mineralization cycle, Heirloom is scaling up major facilities (such as projects in Louisiana) to drive down the cost per ton of permanent carbon removal. 10 Fastest Growing Carbon Capture Companies and Startups10 Fastest Growing Carbon Capture Companies and Startups

2. Industrial Point-Source Capture Leaders

These companies focus on decarbonizing hard-to-abate heavy industries (cement, steel, chemicals, and power generation) where capturing emissions at the smokestack is critical.

• Mitsubishi Heavy Industries (Japan): MHI is an established global heavyweight with decades of experience deploying chemical solvent-based carbon capture tech (via its proprietary KM CDR Process). They have successfully delivered numerous commercial-scale flue-gas capture projects worldwide.

• SLB Capturi (Global): Formed via SLB (formerly Schlumberger) and Aker Carbon Capture, this powerhouse combines decades of oilfield engineering muscle with advanced process tech to tackle massive industrial emissions (such as pulp, paper, and waste-to-energy plants).

• Carbon Clean (UK/USA): Known for its modular, intensified carbon capture technology (CycloneCC), Carbon Clean reduces the physical footprint and cost of retrofitting carbon capture equipment onto existing industrial plants.

3. Permanent Mineralization & Storage Leaders

Capturing carbon is only half the battle; it must be stored permanently so it never returns to the atmosphere.

• Carbfix (Iceland): The undisputed pioneer in mineral storage. Carbfix dissolves captured CO2 in water and injects it deep into basaltic underground formations, where a natural chemical reaction turns the gas into stone in less than two years, permanently locking it away.

Determining who offers the "best" carbon capture depends entirely on whether you mean Direct Air Capture (DAC) - pulling legacy carbon out of the open atmosphere - or Point-Source Capture , which stops industrial emissions at the smokestack before they enter the air.

The carbon capture landscape is led by several standout organizations categorized by their approach:
