Porto Corsini E

Location

The project is located in the offshore area of the Adriatic Sea, near Ravenna, Italy. Specifically, the CO₂ storage site is at the depleted Porto Corsini Mare Ovest gas field.

Project Overview

The Ravenna CCS project is a joint venture between Eni and Snam, aimed at capturing, transporting, and storing CO₂ emissions. This is Italy's first CCS project designed exclusively for environmental purposes.

Phase 1

• The initial phase involves capturing approximately 25,000 tonnes of CO₂ per year from Eni's natural gas treatment plant in Casalborsetti, in the municipality of Ravenna.
• The captured CO₂ is transported through reconverted gas pipelines to the offshore Porto Corsini Mare Ovest platform.
• The CO₂ is then injected and stored at a depth of 3,000 metres in the depleted Porto Corsini Mare Ovest gas field.
• This phase has already achieved a significant reduction in CO₂ emissions, with efficiency rates exceeding 90% and peaking at 96%.

Technical and Environmental Aspects

• The facility is fully powered by electricity from renewable sources, avoiding additional CO₂ emissions.
• The project leverages existing infrastructure, with Snam developing the onshore transport capability by reusing existing pipelines where possible.

Future Expansion

• Phase 2 of the project aims to increase the storage capacity to up to 4 million tonnes of CO₂ per year by 2030, aligning with Italy’s Integrated National Energy and Climate Plan (PNIEC).
• The joint venture will initiate necessary procedures to obtain permits and collaborate with authorities and stakeholders for the expansion.

Economic and Social Impact

• The project is expected to create new job opportunities, with an estimate of over 500 new jobs during Phase 1.
• It supports the decarbonization of highly energy-intensive sectors such as steel mills, cement plants, ceramics, and chemical industries, contributing to Italy’s overall decarbonization goals.

Geological Context

• The storage site is a depleted gas field, which has been repurposed for CO₂ storage. The geological formation consists of sand layers, with a caprock of clay and silt to ensure the secure storage of CO₂.

In summary, the Porto Corsini Mare Ovest site is integral to the Ravenna CCS project, focusing on carbon capture, transport, and storage to support Italy's decarbonization efforts.
