Download our beautiful pitch about the CCUS market
In our CCUS market deck, you will find everything you need to understand the market
CCUS funding activity in 2026 has concentrated on technologies that either capture carbon at industrial sites or turn captured CO₂ into valuable materials, fuels and durable mineral products.
The 12 disclosed financings tracked here total approximately $142.5 million, based on reported dollar figures and contemporary conversions for euro, pound and Canadian-dollar rounds.
Most companies are funding the difficult step between laboratory validation and repeatable industrial deployment, including pilots, manufacturing capacity and first commercial systems.

Insights
- The three largest CCUS funding deals, Rivan Industries, CREW Carbon and D-CRBN, represented about 55% of the $142.5 million reported across these 12 carbon capture, utilization and storage financings.
- Six of the 12 companies use captured CO₂ as a feedstock for fuels, chemicals, textiles, diamond coatings or other materials, showing that carbon utilization remains a major venture funding theme in CCUS.
- Only two companies raised $25 million or more, which suggests that most CCUS startups still need pilot-scale capital rather than the project-finance-sized checks required for full-scale infrastructure.
- Industrial deployment was the central use of proceeds: D-CRBN, Reduciner, sequestra and Mantel are all funding the transition from technical validation to equipment operating with industrial customers.
- Marine and water-based carbon removal appeared in three deals, including Captura, CREW Carbon and pHathom, indicating that water infrastructure is becoming a practical deployment route for durable carbon storage.
- Series A capital accounted for several of the largest rounds, as investors backed companies that had moved beyond early research but still needed funding for demonstrations, engineering and commercial execution.
- Reported valuations were not disclosed for any of the 12 CCUS funding announcements, a common pattern for industrial climate technology businesses whose progress is measured through pilots, performance and customer projects.
- The April to May period produced seven of the 12 financings, making it the busiest stretch in this dataset for carbon capture, CO₂ utilization and mineralization startup funding.
As this chart shows, and as featured in our CCUS market deck, search interest in carbon credits has grown significantly
Summary table of the latest funding deals in the CCUS market as of September 2026
We define the CCUS market as the set of products and services that enable capturing CO₂, conditioning it, moving it, and then either using it or storing it to prevent atmospheric release.
We include CO₂ capture (point-source and direct air), compression/conditioning, CO₂ transport infrastructure and services, utilization pathways, and geological storage (including monitoring and verification directly tied to storage or durable utilization).
We exclude general decarbonization advisory, corporate carbon accounting not tied to specific CCUS projects, trading of carbon credits as a standalone activity, and CO₂ uses that are primarily for short-lived consumption without durable storage.
