LIMENET S.R.L. SOCIETA' BENEFIT

Oceans have regulated the Earth's climate for millennia, absorbing enormous quantities of CO₂ through natural geochemical processes. But the rate at which anthropogenic emissions are accumulating in the atmosphere has outpaced the response capacity of natural cycles, creating an imbalance that requires active carbon removal solutions. Limenet, a benefit company based in Galbiate in Lombardy, has developed a technology that restores and accelerates one of these natural processes: the mineralization of CO₂ into calcium bicarbonate dissolved in seawater. Limenet's process enables permanent storage of carbon dioxide in the ocean in a stable, non-re-emissive form, converting captured CO₂ into calcium bicarbonate — the same compound produced by the natural weathering of limestone rocks that has maintained stable atmospheric carbon balance for millennia. Unlike other carbon capture and storage solutions that require geological cavities or high-cost infrastructure, this approach uses the ocean itself as the reservoir, offering virtually unlimited storage capacity. The business model is B2B, with customized solutions for companies that need to purchase certified carbon credits or demonstrate net removal impacts as part of decarbonization strategies. The carbon removal credits market is one of the fastest-growing segments in the climate-tech landscape, with surging demand from companies that have committed to net-zero targets and are seeking permanent, verifiable removal solutions. Limenet enters this market with a solution that combines scalability — marine infrastructure is available wherever there is coastline — and permanence of storage, two characteristics critical to high-quality carbon markets. A concrete technological response to one of the most urgent challenges of our time.
