The direct air capture systems market is advancing as developers, technology providers, and industrial buyers look for ways to remove carbon dioxide directly from ambient air. Polaris Market Research values the market at USD 147.07 million in 2025, with a 2026 estimate of USD 214.74 million and a projection of USD 4,542.05 million by 2034, reflecting a CAGR of 46.4% from 2026 to 2034. Direct air capture (DAC) works through capture and regeneration: air contacts a material that captures CO₂, which is then separated and collected for storage or further use. Three technology pathways are central: solid sorbent systems, liquid solvent systems, and electrochemical capture.

Solid Sorbent Systems

In solid sorbent systems, air passes through a porous solid material with sites that hold CO₂ molecules. When the material has captured the maximum possible amount, the CO₂ is released through heating or a change in pressure, and the sorbent can be reused. The solid DAC segment led the global market with a 62.4% share in 2025, with lower operating temperatures and material advancements supporting its position. Its modular nature has also helped developers add capacity incrementally.

Research continues into sorbents that perform effectively at lower CO₂ concentrations and maintain performance over multiple cycles, alongside improvements in contactor design, control systems, and component durability. Continued testing of new materials and system components can improve the performance of solid sorbent systems.

Liquid Solvent Systems

Liquid solvent systems introduce air to a solvent that reacts with carbon dioxide. The mixture is then treated to isolate CO₂, and heating is a common means of regenerating the solvent. The liquid DAC segment is projected to grow at a 48.1% CAGR, driven by ongoing project development, efforts to improve performance and reduce energy consumption, and rising investment in commercial facilities. 1PointFive is positioned in solvent-based liquid DAC under Occidental, with corporate offtake deals that include Microsoft and United Airlines Ventures. As more projects scale up from the pilot stage, demand for equipment based on liquid solvent systems is expected to increase.

Electrochemical Capture

Electrochemical capture uses an electrical potential to regulate the capture and release of carbon dioxide. An electrical energy input leads to a chemical transformation in the capture medium, helping transport CO₂ independently of thermal regeneration. RepAir Carbon, based in Israel, is positioned in electrochemical DAC, claims substantially lower energy intensity, and is at a pilot or early commercial stage. In June 2026, Siemens partnered with Ucaneo to support the scale-up of electrochemical DAC through automation and digitalization technologies. By comparison, traditional carbon capture takes CO₂ from point-source industrial emissions and must sit near the emitting facility, whereas DAC can be located flexibly.

Design and Energy Trends

The report notes a shift toward modular DAC plant designs that can be built in smaller increments. Developers need not build a complete large plant immediately, and individual modules can be tested before more are added, enabling staged investment rather than paying all costs upfront. Skytree, a Netherlands-based provider of modular solid DAC, offers compact units for vertical farming and industrial CO₂ supply.

Energy is the other design variable. The benefit of carbon removal may be reduced if a plant relies on high-emission energy, so efforts are underway to couple DAC systems with low-carbon energy sources for power and heat. Energy availability also affects project location and operating hours, and access to nearby low-carbon energy sources can reduce emissions from the project.

Regional Snapshot

North America led the market with a 45.8% share in 2025, and the US Department of Energy has been engaged in DAC hubs across Louisiana, Texas, California, Utah, and North Dakota. Asia Pacific is projected to grow at a CAGR of 49.7%, Latin America at 43.2%, and the Middle East and Africa at 41.7%, while Europe accounted for a 27.4% share in 2025. In February 2026, Climeworks and the Royal Commission for Jubail and Yanbu signed an agreement to assess a DAC demonstration plant at Jubail in Saudi Arabia.

Key Players in the Direct Air Capture Systems Market

Climeworks, based in Switzerland, uses solid DAC with sorbent filters and has the largest operating capacity to date; its Generation 3 technology claims twice the capacity and roughly half the energy use of its predecessor. The report's company list also includes 1PointFive, Avnos, Capture6, Carbon Capture Inc., Carbon Collect Limited, Carbyon (acquired by Airhive), Deep Sky, Heirloom Carbon Technologies, Infinitree, Mission Zero Technologies, Noya, Octavia Carbon, Prometheus Fuels, RepAir Carbon, Skytree, Soletair Power, Spiritus, Sustaera, and Zero Carbon Systems. In July 2026, Airhive acquired Carbyon, combining their solid-sorbent DAC technologies.

Conclusion

Technology choice, plant design, and energy sourcing are central to how the direct air capture systems market matures. Each capture pathway carries its own trade-offs, and the competitive environment includes both large centralized projects and small firms developing specialized systems. Demonstration projects and collaboration will remain crucial for validating new approaches as the industry moves from early commercial projects toward broader deployment.
