CarboMiner, a direct air capture company founded by a Ukrainian team and registered in Nicosia, Cyprus, builds transportable machines that capture CO2 from ambient air with absorbent materials and release it using an electrochemical pH swing, so greenhouses and food producers can use it on site instead of buying fossil CO2. It was selected in the EIC Accelerator's June 2023 cut-off with blended finance and received an EU grant of €1.55 million for C-DAC, "Direct Air Capture for on-site CO2 utilization in greenhouses", a €2.21 million project that ran from March 2024 to February 2026, according to CORDIS. The company said the grant would let it scale its machine to 50 tonnes a year and pilot it with greenhouses, according to CarboMiner.
The only public report, to February 2025, says CarboMiner completed the engineering design of the 50-tonne system, optimised its capture materials, fans and monitoring, and cut the energy used by its regeneration electrolyser from 19 MWh per tonne of CO2 in 2023 to 7.8 MWh, according to the CORDIS reporting page. Construction was under way, with quotes from container and electrolyser suppliers and a bill of materials being prepared. The project has ended without a public final report, and no completed 50-tonne system or greenhouse pilot has been announced.

Where CarboMiner Stands Now
CarboMiner's latest news items, from mid-2025, describe conference appearances, including a "solar-powered DAC vision" presented at ECOSUMMIT in Berlin and a sustainable energy forum in Kyiv, according to its news page. Its website footer still gives a Kyiv address. In 2023 it ran a two-week pilot of a 1.2-tonne machine with an international building materials group near Kyiv, according to CarboMiner. No investment round, customer contract or operating plant has been announced since.
"Scaling our Direct Air Capture (DAC) technology from a 1 tCO2/year prototype to a 50 tCO2/year system is a crucial milestone."
CarboMiner, first periodic report to the EICThe Technology: CO2 From Thin Air
Greenhouses add CO2 to boost plant growth and usually buy it as liquefied gas from fossil sources, whose price the report says has doubled in recent years. Air contains only 0.04% CO2, so capturing it takes a lot of energy. CarboMiner's process is fully electric, using an electrochemical pH swing to release the CO2, and its electrolyser still used 7.8 MWh per tonne in early 2025, and the company targets 4.0 MWh.
What the EIC Award Promised, and What the Record Shows
The award promised a 50-tonne-a-year system, tested internally and piloted with greenhouses. By the halfway point the design was complete and construction had begun. Whether the system was finished, tested and installed at a greenhouse within the project is not public, and there is no final report.

The Money
The EU paid 70% of the project. CarboMiner's accounts in Cyprus are not freely available. Whether the EIC Fund invested under the blended finance award, and whether any private investors have joined, has not been announced.
What Cannot Be Checked
Questions for the EIC
Whether the 50-tonne system was built and where it operates, whether a greenhouse pilot took place, whether the EIC Fund invested, and why no final report is public are not public.
Why Europe Should Care
Europe's greenhouses depend on CO2 supplies that have become expensive and unreliable. Local capture from air would decouple them from fossil supply chains. The EIC backed a Ukrainian team to build such a machine; the public record stops before showing whether it works at scale.
What the award promised
A 50-tonne-a-year air-capture system supplying CO2 to greenhouses.
What the record shows
A completed design, lower energy use, and no public evidence of a finished system or pilot.
The Verdict
Halfway documented
CarboMiner made technical progress in the first year of its EIC project. What happened next has not been reported.
