Direct Air Capture Carbon Credits: A Buyer's Guide

Direct air capture (DAC) represents the highest-permanence category of carbon removal available today. Unlike nature-based offsets, DAC credits guarantee geological storage for thousands of years, making them the preferred choice for science-based net-zero targets.

Market Landscape

As of mid-2025, 31 suppliers from 10 countries have sold approximately 2.4 million tonnes of DAC carbon removal credits through 680 orders, according to CDR.fyi. However, the market is highly concentrated: just three companies — 1PointFive, Climeworks, and Heirloom — account for 80% of all DAC credits sold.

Pricing Tiers

DAC credit prices vary significantly based on technology maturity and delivery timeline:

Premium (delivered credits)
$600–$1,000+ per tonne — credits from operational facilities with verified removals
Forward contracts
$200–$600 per tonne — advance purchase agreements for future delivery, typically 3-7 year horizons
Blended portfolios
$100–$250 per tonne — mixed with nature-based removals for lower average cost

Technology Approaches

DAC sellers deploy three primary technology families:

Solid Sorbent Systems

Used by Climeworks and others, these systems pass air over solid chemical filters that bind CO2, then apply heat to release concentrated CO2 for storage. Climeworks' Mammoth plant in Iceland represents the current state of the art.

Liquid Solvent Systems

Pioneered by Carbon Engineering (now integrated into 1PointFive), this approach uses potassium hydroxide solutions to capture CO2, enabling larger-scale facilities like the STRATOS plant in Texas.

Enhanced Mineralization

Heirloom accelerates natural limestone weathering from years to days, offering a potentially lower-cost pathway. Octavia Carbon in Kenya combines solid sorbents with geothermal energy and basalt storage.

What Buyers Should Evaluate

When selecting a DAC credit supplier, corporate sustainability teams should assess:

  • Delivery track record — Only 0.05% of contracted credits have been delivered; understand the timeline risk
  • Storage permanence — Geological storage (1,000+ years) vs. utilization pathways
  • Third-party verification — Look for MRV (measurement, reporting, verification) by independent auditors
  • Additionality — Confirm your purchase directly enables new capture capacity
  • Energy source — Clean energy inputs ensure net-negative lifecycle emissions

Frequently Asked Questions

Q.How does ReqoData verify that listed sellers actually operate DAC facilities?

When you request data, our AI crawls public sources including CDR.fyi registry data, company disclosures, DOE grant records, and third-party MRV reports to confirm operational status and credit availability.

Q.Can I get pricing data for forward purchase agreements?

Yes. Our dataset includes publicly disclosed credit prices and contract terms. Note that many large deals are negotiated privately, so published prices represent indicative ranges rather than guaranteed rates.

Q.Are pre-revenue DAC startups included?

We focus on companies that have sold or contracted carbon removal credits. Early-stage companies without credit sales may appear if they have publicly announced capacity and pricing, but we flag their delivery status clearly.

Q.How current is the supplier data?

Data is collected in real-time when you make a request. Our AI crawls the latest public sources, so you get the most current information available from company websites, registry databases, and industry trackers.
