Carbominer

Carbominer is a hardware startup that has developed modular Direct Air Capture (DAC) technology designed to extract carbon dioxide from the atmosphere. Their approach combines dry and wet capture methods using ion-exchange sorbent, followed by electrochemistry-based regeneration to release the CO2. A key feature of their technology is its ability to utilize intermittent renewable energy and its focus on compact, transportable units rather than large-scale infrastructure. By capturing CO2 locally, the company provides a sustainable supply of carbon for specific industrial applications, setting its technology apart through its energy efficiency and modular design.

The company primarily targets the indoor agriculture sector, providing CO2 to greenhouse operators to enhance photosynthesis and increase crop yields. By offering locally captured, fossil-free carbon dioxide as a service, Carbominer aims to help agricultural businesses adopt more sustainable growing cycles while reducing costs compared to traditional CO2 sources. Beyond agriculture, the technology also supports Direct Air Carbon Capture and Storage (DACCS) initiatives, allowing companies to permanently remove carbon from the air. Based in Kyiv, Ukraine, and Warsaw, Poland, Carbominer has been recognized for its innovation through various awards and accelerator programs, and it is actively working to pilot its units with partners across Europe.
