Limenet has developed a patented technology that converts atmospheric CO2 into calcium bicarbonate, which is then stored in seawater, effectively utilizing natural processes to enhance ocean alkalinity. This method addresses the rapid increase of CO2 emissions and ocean acidification, providing a stable and long-term carbon storage solution that lasts between 10,000 and 100,000 years.

Problem
The rapid increase in atmospheric CO2 levels is causing ocean acidification, endangering marine ecosystems and accelerating climate change. Existing carbon sequestration methods often lack the scalability and permanence needed to address the magnitude of the problem.
Solution
Limenet has developed a patented technology that converts atmospheric or industrial-source CO2 into calcium bicarbonate, a stable compound naturally present in seawater. The process utilizes calcium carbonate, seawater, and renewable energy to transform captured CO2 into an aqueous solution of calcium bicarbonates, which is then safely stored in the ocean. This method not only sequesters CO2 for an estimated 10,000 to 100,000 years but also increases the ocean's alkalinity, potentially benefiting marine life by counteracting acidification. The technology mimics and accelerates natural carbon absorption processes, offering a scalable and eco-friendly approach to carbon removal and storage.
Target Audience
Limenet's primary customers include governments, corporations, and organizations seeking long-term, verifiable carbon removal solutions, as well as industries with significant CO2 emissions looking to offset their carbon footprint.
