Ravenna: Upstream operations and CO₂ storage

Here business and the local area coexist in harmony. We produce gas in a sustainable way and we are creating a hub to store CO₂.

Working in synergy with the local community

Our commitment to the development and maintenance of gas assets has resulted in a major investment plan for the Central Northern District (DICS) of Ravenna. The plan has seen over 1.1 billion euros invested over the last three years. In the next few years an offshore decommissioning plan will also begin. This involves taking down an initial batch of nine offshore facilities. The plan should begin in 2023 or 2024. Upstream activities are in step with the local community, having reached common ground over environmental, economic and social sustainability. Emilia Romagna is a good example of the coexistence of tourism, agriculture and Oil & Gas activities. With a long history of E&P in the area, Italy’s ‘Food Valley’ has developed exceptionally high food and agriculture standards alongside its hydrocarbon fields. The coastal strip between Ravenna and Riccione, home to Eni's gas platforms, also boasts numerous Blue Flag beaches.

In the circular economy initiatives, a program in collaboration with national research institutions was launched to redevelop asset in the decomissioning phase. In particular, activities started up to convert an offshore platform into a marine science park. 

In the gas assets of the Adriatic Sea, development activities concerned:

  • maintenance and production optimization at offshore gas fields Annalisa (Eni’s interest 100%) and Calipso (Eni’s interest 51%)
  • Decommissioning plan to plug-in depleted wells and to remove idle platforms progressed in the year.

In compliance with Italian Ministerial Decree 15 February 2019 “Linee guida nazionali per la dismissione mineraria delle piattaforme per la coltivazione in mare e delle infrastrutture connesse”, a total of six offshore platforms to be removed are currently under the ministerial authorization process. In the circular economy initiatives, a program in collaboration with national research institutions was launched to redevelop asset in the decommissioning phase. Activities started up to convert an offshore platform into a marine science park. In 2021 the IX Collaboration Agreement was signed with the Municipality of Ravenna. The agreement includes:

  • environmental projects by means of studies, monitoring program and environmental protection activities at the coastline areas
  • energy efficiency measures
  • professional training initiatives, programs to support local market and activities
  • social projects and environmental education and sustainable development projects in collaboration with several local stakeholders.

A major CO₂ storage site for Ravenna

Leveraging Carbon Capture and Storage (CCS) technology, we are aiming to build one our biggest centres in the world for CO₂ storage off the coast of Ravenna. In fact, in light of the following, the Ravenna District represents an ideal environment in which to develop the CCUS model, similar to other European projects currently at various stages of their development:

  • Eni's natural gas production assets in the Adriatic offshore are characterised by depleted or depleting fields that can be converted quickly and safely
  • It has existing infrastructures both on land and at sea that are currently serving the fields in production and that will operate in synergy with the new CCS developments since a small part will be reused, allowing for a reduction in both the cost of and the time frame for implementation and moreover eliminating the need to use or commit new areas or land resources
  • Its location is favourable in terms of transport and connecting infrastructure (presence of a large industrial port, land connections with the railway line and the national gas network) and the presence of a developed industrial system and culture
  • It has specific technical skills and knowledge of the subsoil acquired over decades of mining activity, which can be effectively converted for the purposes of decarbonization and the energy transition
  • It benefits from the presence in the area of a highly competent industrial sector that has developed over the years.

There will be a Phase 1 starting in 2023, and a Phase 2 starting in 2027. During Phase 1 carbon dioxide will be captured by Eni’s natural gas treatment plant in Casalborsetti (Ravenna), then conveyed toward the Porto Corsini Mare Ovest platform, and lastly injected into depleted gas field with the same name, offshore Ravenna, for an overall storage capacity of 25,000 tons of CO2. In Phase 2, 4 million tons of CO2 will be stored, to contribute to the decarbonisation of steel mills, cement plants, ceramic and chemicals industries, and “hard to abate” sectors in general. Overall, the scheduled activities will help create new work opportunities, with a total estimate of over 500 new jobs during the first phase of the project alone. In Italy, for instance, in 2019, “hard to abate” sectors issued approximately 67 million tons of CO2, out of a national total of 340 millions, that is, 20% of the total and 42% of the industrial sector, responsible for the emission of 158 million tons of CO2 (according to ISPRA 2021). The timeline is proceeding and, in December 2022, Eni and Snam signed an agreement to establish an equally owned joint venture to develop and manage Phase 1, including also the studies and preparation activities for subsequent development phases.

The large storage potential of the Adriatic offshore fields, which, on the basis of preliminary assessments, is estimated to be up to 500 million tonnes of CO2, gives the project flexibility for further industrial expansions with an annual storage capacity that can be easily increased from the initial one to meet the decarbonization needs of additional national and even international industrial third-party sites.

The CCUS model in Ravenna represents a great opportunity not only for Eni, but also for Italian industry to create one of the world's largest CO2 storage hubs and the leading hub not only for Italy but also for all of Southern Europe.

2021 Eni local sustainability Report for Ravenna

Every year, we publish a complete report on the activities carried out by Eni’s companies within the Ravenna multi-company site to highlight the contribution to the path towards Just Transition undertaken by Eni, towards to local development, to protect and enhance the territory, to improve the quality of life of its residents. Over the last years, our just transition path brought the Ravenna industrial hub at the heart of Eni’s decarbonisation and circular economy strategies, with initiatives being implemented or recently launched, such as the COcapture and storage project, Ponticelle’s redevelopment, and the research projects on latest-generation elastomers. In 2021, despite the context characterized by the ongoing emergency status due to the pandemic, we designed and implemented the main innovation and development interventions.

The document forms part of Eni’s sustainability reporting, which also includes the 2021 Consolidated Disclosure of Non-Financial Information (NFI), drafted in accordance with Legislative Decree 254/2016, and Eni’s 2021 Sustainability Report. These can be consulted for further information.
