Limenet has developed its first industrial plant with a Technology Readiness Level of TRL 7.
The plant was built in Augusta, Sicily and is able to store 800 tons of CO₂ per year.
With this project, Limenet has validated the production of decarbonised calcium hydroxide based on Limenet’s patented technology.
The core of the technology is the electric calcination of calcium carbonate, and the permanent storage of CO₂ produced during calcination in sea water in the form of bicarbonates.
Decarbonized calcium hydroxide is used to reduce emissions for industries or other “hard to abate” emitters.

Limenet has designed and built a technological industrial prototype TRL6.
Metrics:
- Maximum production of 1 kg/h of decarbonized calcium hydroxide
- 1kg/h maximum CO₂ storage capacity in the form of calcium bicarbonates
- Total production of about 250 kg of decarbonized calcium hydroxide which was used to refill and produce the first negative CO₂ emissions. This was about 150 kg.
The plant was used to analyze the chemical stability of calcium bicarbonates over time and their qualitative effect on marine biota naturally present in sea water.
