Carbon capture has a key role at the centre of industrial decarbonisation, with direct air capture and point-source systems now attracting major investment from energy, engineering and climate-tech groups.
The market is still nascent, but momentum is building as companies and governments seek durable ways to remove or avoid residual emissions that are difficult to eliminate through electrification alone.
The platforms in this list represent the sector’s most visible contenders, spanning modular capture units, mineralisation, electrochemical systems and large-scale storage infrastructure. Together, they illustrate how carbon capture is shifting from promise to commercial deployment.
10. Deep Sky
- HQ: Montréal, Québec, Canada
- CEO: Alex Petre
- Founded: 2022
Deep Sky is pursuing a portfolio approach to carbon removal, acting less like a single-technology provider and more like a platform developer.
The company is building commercial sites that can host and scale a range of removal technologies, with storage and clean power as critical enablers. That model gives it a systems-level role in the market, linking technology, infrastructure and offtake.
Deep Sky’s ambition is to help turn carbon removal into bankable industrial infrastructure rather than a collection of isolated pilots.
9. Svante
- HQ: Vancouver, British Columbia, Canada
- CEO: Claude Létourneau
- Founded: 2007
Svante has become a prominent Canadian carbon capture company by combining filtration materials with modular capture equipment.
The business serves both industrial emissions and direct air capture use cases, which gives it flexibility across markets. Its technology is built around engineered filters and rotating contactor machines, designed to make capture more efficient and deployment more repeatable.
Svante’s growth reflects broader investor interest in hardware that can move from demonstration to commercial roll-out.interviews.
8. Carbon Clean
- HQ: London, UK
- CEO: Aniruddha Sharma
- Founded: 2009
Carbon Clean has built a reputation as a practical industrial carbon capture company, targeting sectors where emissions are hardest to eliminate. Its technology is deployed across multiple sites worldwide and is designed to lower both operating cost and environmental impact.
Rather than positioning itself as a pure future bet, the company is focused on commercial deployment now. That operational emphasis has made Carbon Clean one of the better-known names in point-source capture.
7. Mission Zero Technologies
- HQ: London, UK
- CEO: Nicholas Chadwick
- Founded: 2020
Mission Zero Technologies is one of the more technically ambitious British carbon capture start-ups, with a focus on direct air capture and electrochemical approaches.
The company says its system is designed to recover high-purity CO₂ while using less energy than conventional methods. Its appeal lies in versatility: a compact, climate-first platform that could suit future distributed capture deployments.
From its London base, Mission Zero is trying to prove that next-generation DAC can be both practical and commercially relevant.
6. CarbonCapture Inc.
- HQ: Los Angeles, California, US
- CEO: Adrian Corless
- Founded: 2019
CarbonCapture Inc. is focused on modular direct air capture systems that can be assembled into larger arrays for industrial-scale removal.
The company’s engineering-led approach emphasises mass production, efficiency and AI-supported control systems. Its aim is to cut the cost of atmospheric carbon removal by designing machines that are easier to deploy and scale.
In a crowded market, CarbonCapture is trying to stand out through modularity and manufacturability rather than one-off flagship plants.
5. Heirloom
- HQ: San Francisco Bay Area, California, US
- CEO: Shashank Samala
- Founded: 2020
Heirloom is built around carbon mineralisation, using naturally occurring chemistry to pull CO₂ from the air and lock it away.
The company has gained attention for its cost ambition and for presenting direct air capture in a more nature-based, scalable form. Its strategy is to make removal durable, commercially viable and compatible with large-scale deployment.
Heirloom’s rise reflects investor appetite for technologies that promise both permanence and lower costs than many early DAC approaches.
4. Mitsubishi Heavy Industries
- HQ: Tokyo, Japan
- CEO: Eisaku Ito
- Founded: 1934
Mitsubishi Heavy Industries is a long-established industrial group that has placed carbon capture within a wider net zero strategy.
The company has made carbon neutrality a central target and is positioning its capture technologies as part of that long-term industrial transition.
Unlike newer start-ups, MHI brings manufacturing scale, process engineering and a global industrial footprint. That combination gives it influence in large infrastructure projects where reliability and integration matter as much as innovation.
3. SLB Capturi
- HQ: Oslo, Norway, and Houston, Texas
- CEO: Guillaume Verhaeghe
- Founded: 2024
SLB Capturi brings oilfield engineering and carbon capture expertise together in a modular industrial platform.
The joint venture between SLB and Aker Carbon Capture is built around standardised capture technology designed to reduce onsite installation work and improve cost efficiency. Its strength lies in deployment, not just design, with the aim of helping heavy industry cut emissions at scale.
The company’s commercial case rests on practical integration, faster installation and broad applicability across industrial sectors.
2. 1PointFive
- HQ: Houston, Texas, US
- President & General Manager: Michael Avery
- Founded: 2020
1PointFive is a major US-backed carbon removal player, combining carbon capture, utilisation and sequestration in one industrial offering.
The company is building large-scale direct air capture capacity and says it has secured geological storage for billions of tonnes of CO₂. Its pitch is straightforward: give companies a measurable way to address residual emissions while building out the infrastructure for long-term storage.
With its first major facility under development, 1PointFive is aiming to move carbon removal from pilot stage to industrial reality.
1. Climeworks
- HQ: Zürich, Switzerland
- Co-Founders: Christoph Gebald and Jan Wurzbacher
- Founded: 2009
Climeworks is one of the best-known names in direct air capture, turning a once-niche climate concept into a commercially recognised removal platform.
Its systems extract carbon dioxide from ambient air and store it permanently underground, positioning the company at the centre of the carbon removal market. Backed by high-profile projects in Iceland and a growing roster of corporate buyers, Climeworks has helped define the commercial language of durable removals.
The company’s appeal lies in scale ambition, technical credibility and a clear focus on permanent storage.
