Our projects for the capture, transportation, storage and reuse of CO₂ (CCUS), a set of technologies that are indispensable for lowering emissions.
The technological chain of capture, transport, storage and utilisation of CO₂, (CCUS) allows carbon dioxide emissions to be captured directly from the industrial plants that generate them.
Capture and storage of CO₂ (CCS) are currently available and effective solutions for decarbonising hard-to-abate sectors, i.e. industries where, due to both high energy consumption and the nature of their production cycles, there are currently no equally effective technological alternatives (e.g. steel, cement, paper and chemical industries).
The importance of the CCUS for the energy transition is emphasised by major international organisations, such as the International Energy Agency (IEA), the International Panel on Climate Change (IPCC), the International Renewable Energy Agency (IRENA) and the United Nations. Also at the international level, these projects are supported by the European Union as part of the EU Industrial Carbon Management Strategy1, as well as by the United Kingdom and the United States of America. This is why we have made it an element of our decarbonization pathway, pursuing CCS projects and supporting research in CCU.
For Eni, CCS is a key lever for the energy transition, both for the decarbonization of its own operations and for third-party industries. With the projects we have already launched in Italy and the United Kingdom, we have secured a leadership position in the sector, while we are planning to develop further initiatives in North Africa, the Netherlands, and the North Sea. In 2025 we expect to launch the new CCUS satellite company, consolidating our projects under a single entity and leveraging our technical and financial expertise.
Eni's approach to CCUS also includes monitoring, before, during, and after the injection of CO2 into the reservoir. These activities, carried out through sensor networks and the use of robotic systems, cover the surface, subsurface and offshore environment.
In 2023 we started the international research project HERCCULES, which is supported by us and other partners and coordinated by the Energy and Environment Laboratory Piacenza (LEAP). The initiative is financed as part of the Horizon Europe framework programme with European funds amounting to approximately thirty million euros. The aim of the project is to develop innovative CO2 capture technologies for the cement and waste-to-energy sectors by setting up demonstration plants in two cement plants and one waste-to-energy plant located in Northern Italy and in Greece.
Carbon Capture and Storage (CCS) is an important tool to support hard-to-abate industries in reducing their emissions. Here are some numbers that testify to our commitment.

With the launch of the Ravenna CCS project on the Ravenna coast and the development of HyNet North West in Liverpool Bay, we are conducting our Carbon Capture and Storage (CCS) activities, establishing ourselves as industry leaders.
Ravenna CCS is the first project in Italy for the capture, transport and permanent storage of CO2, developed through a Joint Venture between Eni and Snam. Phase 1, which began in September 2024, aims to capture, transport, and store 25,000 tonnes of CO2 per year from the emissions of Eni’s natural gas processing plant in Casalborsetti. With Phase 2, scheduled to start before 2030, storage capacity will progressively increase, and Ravenna CCS could become the main CCS hub for Southern Europe and the Mediterranean.
HyNet North West, located in Liverpool Bay, is one of the UK’s flagship CCS projects and is actively supported by the UK Government for its contribution to reducing hard-to-abate emissions, in line with the country’s goal of storing 20-30 million tonnes of CO2. Its objective is to transform one of the country’s most energy-intensive industrial regions into one of the world’s first low-carbon industrial clusters. The first storage activities are expected to begin in the second half of this decade, with progressive increases from 2030 onwards.

We support research and innovation across the entire supply chain of CO2 capture, storage and utilisation. Regarding the possibility of utilisation (CCU), in particular, we are working on a mineralisation technology that allows carbon dioxide to be 'recycled' in the production of Supplementary Cementitious Material (SCM) suitable for the formulation of Portland-type cements, with a high standard for use in the construction industry. The reaction at the base of the process, which involves the combination of CO2 with minerals containing silicates, occurs spontaneously in nature but over geological timescales. Eni's innovation consists in having developed a technology that accelerates the reaction to a few hours and gives the product properties that make it suitable for the formulation of cements.
