Market Definition and Scope

The Direct Air Capture Materials Market covers the sorbents, solvents, membranes, and structured contactor media engineered to bind atmospheric CO2. It spans amine-impregnated and metal-organic framework sorbents, potassium and sodium hydroxide solvents, and polymeric or ion-exchange membranes supplied to DAC equipment integrators, project developers, and carbon storage and utilization operators.

The scope excludes DAC plant hardware such as fans, compressors, and heat-exchange equipment, and excludes point-source carbon capture sorbents and solvents used on flue-gas streams, which follow separate specification and regeneration requirements from ambient-air capture chemistries.

Market Trends

Sorbent Formulators Are Moving From Amine-Impregnated Media Toward Metal-Organic Frameworks and Zeolites

Solid Sorbent-Based DAC, the leading technology segment, is shifting away from first-generation amine-impregnated substrates toward metal-organic frameworks and zeolites that desorb CO2 at lower temperatures. ASTM and ISO working groups are extending material-qualification protocols to these chemistries, giving buyers a specification path that amine sorbents lacked. Formulators serving contactor OEMs absorb the switching cost first. Over the forecast period, this redirects sorbent replacement spend toward higher-value framework and zeolite grades rather than volume amine sorbent.

Liquid Solvent Producers Are Re-Engineering Around Regeneration Energy, Not Absorption Capacity

Liquid Solvent-Based DAC systems built on potassium and sodium hydroxide have historically competed on CO2 absorption capacity. Solvent suppliers now compete on the energy needed to regenerate the sorbent in the calciner, since that cost sets the delivered price per ton captured. The European Union’s Directive 2009/31/EC adds purity and monitoring obligations for CO2 destined for geological storage, pushing solvent blends toward tighter carbonate control. Formulators supplying storage-linked projects bear the reformulation cost first.

Carbon Storage Is Anchoring Materials Demand Ahead of Utilization Pathways

Carbon Storage leads the application axis, and capital is following it. The broader direct air capture market moved from USD 147.0 Million in 2025 toward a projected USD 3.34 Billion by 2033, with storage-bound projects the primary destination for that spending. Solid sorbent and liquid solvent suppliers tied to storage offtake capture most of this growth, while electrochemical and membrane routes tied to utilization remain smaller, earlier-stage segments through the forecast period.

Growth Drivers and Restraints

EU Storage Permitting Under Directive 2009/31/EC Is Locking In Purity Specifications for Capture Materials

The European Union’s Directive 2009/31/EC, as amended, requires storage-complex characterization, injection monitoring, and financial security for geologically stored CO2, which pushes operators toward materials that deliver certified, verifiable CO2 purity. Amine-based sorbents and hydroxide solvents used ahead of storage-linked injection fall under REACH registration through the European Chemicals Agency, adding a compliance layer that favors formulators with existing chemical dossiers. Liquid Solvent-Based DAC and Solid Sorbent-Based DAC suppliers serving European storage projects absorb this qualification cost first.

Financing Flowing Into Direct Air Capture Is Pulling Material Orders Upstream of Plant Construction

The broader direct air capture market moved from USD 147.0 Million in 2025 toward a projected USD 3.34 Billion by 2033, a 46.3% CAGR. Developers are pre-committing to sorbent and solvent offtake years ahead of plant commissioning to lock in supply. The American Chemistry Council’s tracking of formulator capacity announcements shows this ordering concentrating in Solid Sorbent-Based DAC, the leading technology segment, ahead of membrane and electrochemical routes still in pilot scale.

Standards Bodies Are Building Qualification Pathways That Reduce Buyer Risk on New Sorbent Chemistries

ASTM and ISO working groups are extending material-testing and qualification protocols to metal-organic framework and zeolite sorbents, giving contactor OEMs a documented basis for approving chemistries beyond first-generation amines. That qualification pathway lowers technical risk for buyers switching sorbent suppliers mid-contract, a switching cost that previously locked amine incumbents in place. Solid Sorbent-Based DAC’s framework and zeolite sub-segments gain OEM approval faster as a result, redirecting new specification wins away from impregnated-amine grades.

Regeneration Energy Intensity Sets a Cost Ceiling on Amine and Solvent Chemistries

Thermal regeneration, whether temperature-swing desorption for solid sorbents or calciner reheating for hydroxide solvents, consumes energy roughly proportional to the mass of CO2 released, and that energy line sets a floor under delivered cost per ton captured. US EIA industrial power price data show this cost is least forgiving for Liquid Solvent-Based DAC’s high-temperature calciner step, keeping solvent-route material suppliers dependent on low-cost power siting rather than sorbent performance alone.

Demand Is Concentrated in a Narrow Set of Storage-Linked Projects, Exposing Suppliers to Single-Region Cycles

Within the broader direct air capture market, North America accounted for 46.7% of activity in 2025, concentrating early sorbent and solvent offtake among a small number of US storage-linked projects. Material suppliers built around that pipeline carry exposure to single-region permitting delays and financing cycles rather than diversified geographic demand. Solid Sorbent-Based DAC and Liquid Solvent-Based DAC formulators tied to those projects absorb the resulting order volatility most directly.

Regional Analysis

Asia Pacific held the largest share of the direct air capture materials market in 2025, at 40.0%. Japan’s Green Innovation Fund, administered by NEDO, channels state R&D financing into sorbent and capture-train development, positioning domestic manufacturers ahead of commercial-scale deployment. Regional demand centers on solid sorbent chemistries suited to humid, variable-climate operation rather than the alkaline-solvent trains more common in drier basins. Government-backed pilot financing, rather than voluntary carbon markets, is the primary channel bringing new sorbent formulations to field trial in the region.

North America accounted for 28.0% of the market in 2025. The finalized Internal Revenue Code Section 45X Advanced Manufacturing Production Credit gives US-based sorbent and electrode-material producers a direct cost offset, anchoring a cluster of developers, including 1PointFive, Heirloom Carbon Technologies, and Global Thermostat, around domestic manufacturing rather than imported base materials. That fiscal structure ties material margins to production volume, not to carbon-price movements alone, which is a distinct commercial logic from the credit-driven build-out seen in other capture segments.

Europe held 20.0% of the market in 2025. Climeworks opened its Mammoth facility in Iceland in May 2024, with a design capacity of 36,000 tonnes of CO2 capture per year, the largest sorbent-based DAC plant running commercially in the region. Geothermal power access, rather than a specific EU subsidy, underwrites Iceland’s cost position, and it is shaping where European sorbent suppliers locate qualification testing. Basalt-hosted mineralization storage nearby differentiates the region’s disposal route from the saline-aquifer injection more common elsewhere.

Segment Analysis

By Material/Technology

• Solid Sorbent-Based DAC (largest) – DAC systems that pass ambient air over amine- or zeolite-coated solid materials which chemically bind CO2 for later release through heating or vacuum
• Amine-Based Sorbents

• Impregnated Amine Sorbents
• Grafted Amine Sorbents

• Metal-Organic Frameworks (MOFs)
• Zeolites
• Activated Carbon Sorbents
• Liquid Solvent-Based DAC – DAC systems that contact air with an aqueous alkaline solution, such as potassium hydroxide, which absorbs CO2 before regeneration in a high-temperature calciner

• Potassium Hydroxide (KOH) Solvents
• Sodium Hydroxide (NaOH) Solvents
• Amine-Based Liquid Solvents
• Electrochemical DAC – DAC systems that use electrically driven redox reactions or pH-swing cells to capture and release CO2 without relying on thermal sorbent regeneration

• Electro-Swing Adsorption (ESA)
• Electrodialysis-Based Systems
• Electrolysis-Based Systems
• Membrane-Based DAC – DAC systems that use selectively permeable polymer or inorganic membranes to separate CO2 molecules from ambient air based on differential diffusion rates

• Polymeric Membranes
• Facilitated Transport Membranes
• Ion-Exchange Membranes
• Hybrid DAC Systems – DAC configurations that combine two or more capture mechanisms, such as sorbent and membrane stages, within a single integrated process train

Solid Sorbent-Based DAC leads the material and technology segmentation in 2025, ahead of liquid-solvent, electrochemical, membrane, and hybrid configurations. Amine-impregnated and zeolite sorbents regenerate at lower temperatures than the aqueous potassium-hydroxide trains used in solvent-based systems, cutting the thermal energy load per tonne captured and letting suppliers ship modular contactor units rather than build a calciner on site. That lower-temperature regeneration is also why solid sorbents dominate the commercial plants running today, including Climeworks’ facility class. Electrochemical DAC, built around electro-swing adsorption and electrodialysis cells, is positioned to grow fastest over the forecast period. Removing the thermal-regeneration step entirely ties its capture cost to grid electricity price rather than heat-supply logistics, an advantage that widens as renewable power gets cheaper and more available on-site.

By Application

• Carbon Storage (largest) – Applications where captured CO2 is compressed and injected into deep geological formations such as saline aquifers or depleted reservoirs for long-term sequestration rather than reuse
• Geological Storage

• Saline Aquifers
• Depleted Oil & Gas Reservoirs
• Basalt Formations
• Mineralization
• Carbon Utilization – Applications where captured CO2 is converted into products such as synthetic fuels, chemicals, building materials, or used as a feedstock in industrial processes

• Food & Beverages
• Chemicals & Fuels
• Building Materials
• Agriculture
• Enhanced Oil Recovery/Other Uses – Applications where captured CO2 is injected into aging oil reservoirs to boost hydrocarbon extraction, alongside niche uses like food-grade carbonation or greenhouse enrichment

• Enhanced Oil Recovery
• Enhanced Coal Bed Methane Recovery
• Other Uses

Carbon Storage is the leading application in 2025, ahead of utilization and enhanced-oil-recovery pathways. Injecting captured CO2 into saline aquifers or basalt formations for permanent sequestration lets an operator sell a verified removal credit without needing a buyer for a finished product, which keeps offtake risk low for early DAC operators. Carbon Utilization is set to expand at the fastest pace through 2035. Turning captured CO2 into synthetic fuels, chemicals, and building-material inputs gives sorbent suppliers a second revenue path beyond storage credits, pulling demand toward higher-purity sorbent and membrane grades capable of delivering fuel-grade CO2 streams rather than a bulk stream destined only for injection.

Competitive Landscape

The direct air capture materials market is led by a group of specialized technology developers rather than a small number of dominant suppliers, with Climeworks AG, Carbon Engineering Ltd., Heirloom Carbon Technologies, Global Thermostat Operations, 1PointFive, Occidental Petroleum Corporation, Holocene Climate Corporation, Mission Zero Technologies, CarbonCapture Inc., and Skytree B.V. named among the active suppliers. Competition centers on sorbent and solvent formulation IP, the energy intensity of regeneration per tonne captured, and a track record of running a plant at design capacity rather than on price alone, since no commodity-grade substitute yet exists for a qualified capture material. Backward integration into project development and storage offtake is a second axis. Occidental Petroleum’s stake in 1PointFive ties its materials demand directly to a captive injection and enhanced-oil-recovery pipeline, a position independent sorbent suppliers such as Skytree and Mission Zero Technologies do not hold. Climeworks opened its Mammoth plant in Iceland in May 2024, with a design capacity of 36,000 tonnes of CO2 per year, extending its lead in commercially operating solid-sorbent capacity and giving it a reference plant other developers lack.

Strategic Outlook

Carbon Utilization is the clearest whitespace through 2035, since a sorbent or membrane supplier that qualifies for fuel- and chemical-grade CO2 streams captures a second buyer beyond storage-credit purchasers. That shift depends on utilization pathways such as synthetic fuels and building materials reaching cost parity with storage-only offtake.

Materials mix should keep moving toward solid sorbents and electrochemical cells as thermal-regeneration energy costs weigh more heavily on solvent-based trains. Buyers are expected to weight qualified capture efficiency and plant track record over price as more facilities move from pilot to commercial operation.
