Eni starts Ravenna CCS CO2 injection

Eni, together with Snam SPA, started reservoir CO₂ injection for Phase 1 of the Ravenna CCS project off the coast of Ravenna, Italy.

Ravenna CCS is the first project to capture, transport, and permanently store CO₂ in Italy exclusively for environmental purposes, Eni said in a release Sept. 3. Phase 1 will capture, transport, and store about 25,000 tonnes/year (tpy) of CO₂ emissions from Eni’s natural gas treatment plant in Casalborsetti in  the municipality of Ravenna.

Once captured, CO₂ is transported to the offshore Porto Corsini Mare Ovest platform through reconverted natural gas pipelines. CO₂ will then be injected and stored at a 3,000 m depth in the depleted Porto Corsini Mare Ovest gas field in the Adriatic Sea.

The project is already delivering a reduction of over 90% in CO₂ emissions from the Casalborsetti plant's chimney, rising to peaks of 96%, the company said. The Ravenna CCS project is fully powered by electricity from renewable sources, avoiding further CO₂ emissions, according to Eni.

With the proposed Phase 2 industrial-scale development, the project is expected to be able to store up to 4 million tpy of CO₂ by 2030.
