Direct Air Capture Technology Landscape

Direct air capture (DAC) removes CO₂ directly from ambient air rather than from point-source emissions. As of 2025, approximately 165 companies are developing DAC technologies worldwide, with 27 plants commissioned and 84 expected operational by end of 2025.

Technology Approaches

Approach	Mechanism	Notable Companies
Solid sorbent	Chemical filters adsorb CO₂; heat releases it for storage	Climeworks, CarbonCapture Inc.
Liquid solvent	Aqueous KOH solution absorbs CO₂; calcination regenerates solvent	1PointFive / Carbon Engineering
Mineral looping	Limestone accelerated to absorb CO₂ in days instead of years	Heirloom
Electrochemical	Electrically driven pH swing captures and releases CO₂	Mission Zero, Verdox

Market and Policy Drivers

The U.S. Inflation Reduction Act raised the 45Q tax credit for DAC from $50 to $180 per tonne of CO₂ permanently stored. The Department of Energy committed $3.5 billion under the Bipartisan Infrastructure Law for four Regional DAC Hubs, each targeting 1 million tonnes per year. An additional $1.8 billion was announced for mid- and large-scale commercial DAC facilities.

Leading Facilities

STRATOS (1PointFive) — Ector County, Texas: Designed for up to 500,000 tCO₂/year. Targeting commercial operations in 2025, making it the world's largest DAC plant.
Mammoth (Climeworks) — Iceland: 36,000 tCO₂/year capacity, operational since 2024. CO₂ is mineralized in basalt rock via Carbfix.
Project Cypress (Heirloom) — Shreveport, Louisiana: Combined 320,000 tCO₂/year across two plants, backed by $550M in DOE funding.

Investment Landscape

Private capital has surged into DAC. Climeworks raised $650 million in 2022, the largest single DAC investment to date. Frontier—a coalition including Stripe, Google, and Meta—has committed over $1 billion in advance carbon removal purchases, with significant allocations to DAC developers like Heirloom, Phlair, and Spiritus.

Frequently Asked Questions

Q.What technology approaches are covered in this dataset?

The dataset includes solid sorbent, liquid solvent, electrochemical, and mineral looping DAC technologies, as well as hybrid approaches. Each company entry specifies its primary technology type.

Q.How is capture capacity data sourced?

Capacity figures are gathered from public sources including company announcements, DOE filings, and IEA databases at the time of your request. AI crawls the web for the latest available data rather than relying on a static database.

Q.Does the dataset include pre-revenue startups?

Yes. The dataset covers the full spectrum from early-stage R&D companies to commercially operational developers. The deployment stage field lets you filter by maturity level.

Q.Can I filter by companies eligible for 45Q tax credits?

You can specify criteria such as US-based operations or minimum capture thresholds (1,000+ tCO2/year) that align with 45Q eligibility requirements when customizing your request.

Q.How is this data collected?

When you place a request, AI agents crawl publicly available web sources—company websites, regulatory filings, press releases, and industry databases—to compile and structure the data. All collection respects robots.txt and site terms of service.
