Our activities in Ravenna

Eni and Snam are working on a CO₂ storage facility off the coast of Ravenna that will use depleted gas fields to contain carbon hydroxide emissions from the industrial districts.

Survey on the potential market for CO₂ transport and storage at the Ravenna site

As part of the Ravenna CCS project, Eni and Snam are launching a collection of non-binding expressions of interest for CO2 transport and storage. The objective is to involve stakeholders in the modular and integrated development of CO2 transport in the Italian industry, to launch the collection of technical/economic data to identify the optimal transport modes and to understand market interest in CO2 transport and storage at the Ravenna site.

Survey on the potential market

Decarbonization creates new opportunities for growth

The Ravenna CCS consists in a CO₂ storage facility in which carbon dioxide emissions will be stored in depleted gas fields in the Adriatic Sea using the Carbon Capture and Storage (CCS) methodology. The goal is to contribute to reducing the emissions of industrial districts to make them more sustainable and competitive in the market, thereby creating the conditions for new opportunities for economic growth through decarbonization.

Thanks to the admission by the European Commission of the Callisto integrated Carbon Capture and Storage (CCS) project to the list of Projects of Common Interest (PCI Projects), the Ravenna COstorage hub will play a key role in the creation of a high-tech international supply chain in the decarbonization sector. Admission to the CIP project list will enable the project, once it has completed the steps of the current process, which is expected to be concluded in 2024, to be eligible for the Connecting Europe Facility Fund (CEF), which is intended to provide non-reimbursable funding to support studies and the development of infrastructure for the reception, transport and storage of CO2.

Capturing, transporting and storing CO₂

The plan is to capture carbon dioxide directly from industrial chimneys, isolate it from other flue gases and transfer it via underground pipelines to the future pumping station at Casal Borsetti. This plant currently receives and processes natural gas from offshore fields and will be converted for its new purpose. From there, CO₂ will be pressurised and transported to offshore platforms where, using existing wells, it will be injected into depleted reservoirs that are now being repurposed for long-term storage. Once it reaches the deepest layers of the subsurface, more than 2,500 metres below the seabed, the CO₂ will be locked in the same geological trap that had caused it to accumulate there over millions of years. Scientifically speaking, carbon dioxide is essentially the carbon component of methane and other gases that were extracted in the past years. Once adapted for this new purpose, these reservoirs will not be available for further production cycles. To transport CO₂ - an inert gas that is neither flammable nor explosive - the existing pipelines will mostly be reused, after they have been modified and upgraded.

Some data about the project

Exploiting the great capacity of the Adriatic sea’s depleted natural gas fields, the Ravenna hub is set to become one of the world's largest CO₂ storage sites and the largest in the Mediterranean.

The project involves an initial test phase, to be launched in 2024, with the aim of capturing 25,000 tonnes of CO₂ from Eni's natural gas processing plant at Casalborsetti, in the province of Ravenna. Once captured, the CO₂ will be piped to the Porto Corsini Mare Ovest platform, from where it will be injected into the depleted gas field by the same name off the coast of Ravenna.

When fully operational, starting in 2027, 4 million tonnes of CO₂ are expected to be stored to contribute to the decarbonization of hard-to-abate industrial sectors.

From 2030 onwards, the significant capacity of these reservoirs could allow for an increase in volume, potentially reaching more 16 million tonnes per year, depending on market demand.

A unique opportunity

The Ravenna CCS project aims to establish itself as a global centre of excellence for carbon capture and storage, with a total capacity of over 500 million tonnes (Mton). The expansive capacity of the depleted Adriatic reservoirs will allow for a gradual increase in storage volume, starting at 4 million tonnes per annum (Mtpa) from 2027 - the planned launch date - and rising to 16 Mtpa after 2030. This progression will accelerate the decarbonization of an expanded range of industrial activities. Once activated, the project will immediately reduce up to 90% of the Ravenna district and Italian's industrial CO₂ emissions, such as those from thermal power plants or the so-called hard-to-abate sectors (e.g. (cement, steel, chemical and petrochemical industries, etc.), which lack effective decarbonization solutions in the short to medium term. By harmonising Eni's extensive knowledge of reservoirs with Snam's decades of experience in natural gas transport and storage and the world's most advanced techniques in emissions capture, the depleted gas reservoirs under the Adriatic sea will be repurposed, thus helping Italy and Europe reach their decarbonization targets. In the meantime, regardless of this new industrial plan, the production of natural gas is on track to be fully phased out in the coming years, in line with the decommissioning strategies agreed with the relevant authorities.


Enhancing skills and converting infrastructure

The execution of the Ravenna CCS project will make it possible to upgrade and enhance of already available skills, for example in logistics and offshore operations - sectors known for their highly skilled workforce. The conversion of approximately 10% of the current infrastructure, such as pipelines and offshore facilities, will not only accelerate the achievement of ambitious decarbonization targets at controlled costs, but will also ensure that the project leaves no footprint on the local environment. The remaining 90% of existing infrastructure will be gradually phased out in line with current regulatory requirements. All production wells, including those associated with converted storage fields, will be systematically phased out.

Preserving the competitiveness of the manufacturing district

In addition to assisting Italy in its decarbonization efforts, the Ravenna CCS project has the potential to bring significant economic benefits to Ravenna's industrial district and, more broadly, to the entire Italian manufacturing sector. The ability to capture industrial emissions will usher in an ecosystem of products and services characterised by reduced CO₂ emissions, stimulating both economic growth and job creation. A key element to highlight is the minimisation of the risk of companies relocating to non-EU countries that offer more relaxed environmental standards. The trend, known as “carbon leakage”, not only damages the competitiveness of the eurozone's economy, but is also detrimental to the common goal of curbing global greenhouse gas emissions. The presence of a large hub in the area dedicated to the capture and storage of CO₂ emissions will not only serve to preserve the district's competitiveness, but will also increase its attractiveness with respect to national and international companies seeking to embark on new sustainable industrial initiatives.
