Limenet, a deep tech startup founded by Stefano Cappello, Giovanni Cappello, and Enrico Noseda, recently completed a €7 million funding round to advance its CO2 capture and ocean storage technology. The technology, inspired by the natural carbon cycle, aims to decarbonize lime production and combat ocean acidification.

The funding was led by Cdp Venture Capital and includes support from Fassa Bortolo. Limenet’s process involves capturing CO2 and converting it into bicarbonates in seawater, enabling long-term CO2 storage for over 10,000 years.

The startup, established in 2022 in Galbiate, has opened its first industrial plant in Augusta, Sicily, capable of processing over 800 tons of CO2 annually. Limenet has received a positive verification opinion from Rina and holds ISO 14064-2 certification for its carbon removal method. The technology involves three phases: limestone processing, CO2 reduction using seawater, and storage as calcium bicarbonate.
