Direct Air Capture Systems Market Trends: How Carbon Removal Technologies Are Advancing Climate Action
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.
