Key valuation trends in the CCUS market
Insights
- The top 10 CCUS startups capture approximately 59% of the combined midpoint valuation, showing that market value remains concentrated among a small group of scaled carbon capture platforms.
- Only five CCUS companies reach a midpoint valuation of at least $1 billion, while the median startup valuation is about $80 million. This highlights the large gap between category leaders and emerging technologies.
- Aircapture, Spiritus and Phlair represent about $578 million in combined midpoint valuation after raising $104 million, suggesting strong investor interest in modular and lower-cost direct air capture systems.
- 44.01 and Origen have a combined midpoint valuation of approximately $348 million against $60 million raised, showing the capital efficiency available in permanent carbon mineralization.
- Paebbl and Carbon Upcycling hold approximately $300 million in combined midpoint valuation after raising $84 million, reflecting growing demand for carbon removal technologies linked to cement and construction materials.
- Captura and Equatic reach approximately $200 million in combined midpoint valuation from $70 million in funding, showing that ocean-based carbon removal is attracting meaningful value before large-scale deployment.
- D-CRBN and CREW Carbon have raised a combined $44 million while reaching approximately $263 million in midpoint valuation, indicating premium pricing for differentiated industrial and wastewater carbon pathways.
- Deep Sky carries an estimated midpoint valuation of $180 million after raising $56 million, which suggests that investors value CCUS infrastructure and project aggregation alongside proprietary capture technology.
- CCUS value creation now extends beyond traditional point-source capture. Direct air capture, construction materials, ocean removal and carbon-removal infrastructure all include startups valued above $100 million.

A few word about our methodology
As you can see, we built a database that ranks startups in the CCUS market based on their current valuation.
Estimating CCUS startup valuations is not always straightforward. Many carbon capture, utilization and storage companies do not publicly disclose their valuation. The available information can also vary widely depending on the company and its stage.
To build this CCUS ranking, we applied a structured valuation methodology and cross-checked information across multiple reliable sources.
Whenever possible, we relied on direct disclosures. These include announced valuations from completed funding rounds, public filings for listed companies, or official acquisition prices.
When a CCUS company is publicly listed, we use its current market capitalization as the reference valuation.
If a carbon capture company was acquired and no independent valuation can reasonably be estimated today, we use the acquisition price as the main reference point.
When a startup recently raised capital but the valuation was not disclosed, we estimate the implied valuation using typical dilution levels for that stage of fundraising.
In some cases, we also estimate valuations using operating metrics such as revenue, ARR, contracted carbon removal capacity, project pipelines or customer traction. We combine these signals with valuation multiples from comparable CCUS companies.
When direct financial data is not available, we may rely on carefully selected comparable startups and other signals such as hiring growth, investor quality, technical progress, project development or commercial partnerships.
All estimates follow a strict evidence hierarchy. Recent funding rounds with announced valuations carry the most weight, followed by strong operating metrics and comparable company analysis.
We also carefully evaluate the age of every data point. Recent information carries more weight, while older CCUS valuation data is treated cautiously and adjusted conservatively when necessary.
Whenever information is uncertain or incomplete, we clearly distinguish between confirmed facts and reasonable inferences.
Because valuation data is not always fully public, each CCUS startup in the ranking is assigned a confidence level based on the reliability, recency and consistency of the available evidence.
Full confidence means the valuation is supported by strong and recent evidence. Strong confidence means the estimate is well supported but includes minor inference. Partial confidence means the estimate relies more heavily on indirect signals. Low confidence means available information is limited or inconsistent.
When confidence is lower, we take a more conservative approach by widening the valuation range. This helps reflect the uncertainty and increases the probability that the true valuation falls within the estimated range.
This reflects how we conduct all our research, including the work behind our report covering the CCUS market.
In a world where LLMs hallucinate and unreliable information is everywhere, our goal is simple: provide data you can trust.
If you want the full detail on a specific valuation estimate, feel free to contact us and we will gladly explain.
Finally, know that we update the dataset once per month, so come back here if you need fresh information.
