SAN DONATO MILANESE, Italy — The EU has added the Callisto Carbon Capture and Storage (CCS) project to the European list of Projects of Common Interest.
Eni and Italian utility Snam both put forward the Callisto (carbon liquefaction transportation and storage) Mediterranean CO2 Network integrated CCS project in collaboration with coordinator Air Liquide.
The scheme incorporates the Eni-operated Ravenna CO2 storage hub offshore/onshore eastern Italy, a co-development with Snam. Phase 1 began late last year. The aim is to develop Italy’s first full capture, transport and storage chain in Italy.
It involves capturing 25,000 metric tons/year of CO2 per year emitted from Eni’s Casal Borsetti gas power plant for injection into a depleted offshore gas field in the Adriatic Sea. The Italian authorities have awarded a CO2 storage license.
Phase 2, due to start by 2026, will target storage of 4 MMmt of CO2 per year, 1 MMmt coming from industrial plants owned by Eni and the remaining 3 MMmt reserved for third-party industrial emitters.
To date, Eni and Snam have signed a letter of intent with four emitters in the Ravenna industrial area.
Further expansions could bring the volumes up to 16 MMmt/year of CO2. Captured carbon will be stored in more offshore depleted gas reservoirs in the Adriatic with an estimated capacity to store 500 MMmt.
Callisto aims to develop a CCS value chain in southwest Europe, focusing on decarbonization of the industrial areas, initially in Ravenna and Ferrara, Italy, and the Fos-Marseille Hub in France.
Admission to the PCI projects list will allow the development, once it has passed the ongoing process (expected to be completed in 2024), to be eligible for the Connecting Europe Facility Fund, which supports studies and development of infrastructure for the reception, transport and storage of CO2.
Eni aims to transfer its experience in storing gas in depleted fields for decades to repurpose certain upstream facilities into CO2 storage hubs, to decarbonize both its own and third parties' industrial activities with a fast time to market.
