Eni, Snam Launch Italy's First Carbon Capture and Storage Project

Eni and Snam, within the framework of the equal Joint Venture set up for the purpose, have announced the commencement of CO2 injection activities in the reservoir for Phase 1 of Ravenna CCS. Designed to support industrial decarbonisation, Ravenna CCS is the first project for the capture, transport and permanent storage of CO₂ in Italy created for exclusively environmental purposes.

Phase 1 of the project will capture, transport and store CO₂ emissions from Eni’s natural gas treatment plant in Casalborsetti, in the municipality of Ravenna, estimated at approximately 25,000 tonnes of per year. Once captured, the carbon dioxide is transported to the offshore Porto Corsini Mare Ovest platform through reconverted gas pipelines. The CO2 will then be injected and stored at a depth of 3,000 metres in the depleted Porto Corsini Mare Ovest gas field.

The project is already delivering a reduction of over 90% in CO₂ emissions from the Casalborsetti plant’s chimney, rising to peaks of 96% - a notable achievement given the conditions of a carbon concentration of less than 3% and the low level of atmospheric pressure making achieving success more challenging. This excellent performance makes Ravenna CCS the world’s first industrial-scale project with such high levels of carbon capture efficiency.

Another distinctive element of the Ravenna CCS project is that the facility is fully powered by electricity from renewable sources, avoiding further CO₂ emissions.
