About
Limenet is an Italian climate tech company operating an ocean alkalinity enhancement facility in Augusta, Sicily, where CO2 from a nearby biogas plant is combined with hydrated lime and seawater to form calcium bicarbonate discharged to the ocean. The plant has been operational since September 2023 (~800 tpa) with plans to scale, and the company received a Frontier prepurchase in 2025 for zero-carbon quicklime development and raised €7M in December 2025.
