- Approximately 25,000 tons of CO2 is captured annually at the natural gas supply facility operated by Italian company Eni in Ravenna province.
- Through collaboration with NEXTCHEM, a subsidiary of MAIRE, Mitsubishi Heavy Industries becomes the first company to provide CO2 capture technology to an Italian company.
- Successfully recovered CO2 from exhaust gas with significantly lower concentration than conventional exhaust gas sources.
A CO2 recovery plant, to which Mitsubishi Heavy Industries provided its CO2 recovery technology “KM CDR Process™,” has begun operations at a natural gas supply facility in Casalborsetti, Ravenna province, Italy. This is the first full-scale plant operation in Europe for CO2 recovery from combustion exhaust gas. This is the first phase of Italy’s first CO2 capture and storage (CCS) project, Ravenna CCS, launched by Eni S.p.A., the country’s largest integrated energy company, in collaboration with Snam S.p.A. As a first step, CO2 emissions are expected to be reduced by approximately 25,000 tons per year.
Through NEXTCHEM, a subsidiary of MAIRE S.p.A., a major Italian engineering company, Mitsubishi Heavy Industries will provide a CO2 capture technology license and basic design package (PDP) for this project. As a technology integrator, NEXTCHEM collaborated with KT (Kinetics Technology S.p.A.), also a member of MAIRE, to coordinate the engineering, procurement, and construction (EPC) of the CO2 recovery plant and delivered it.
This recovery technology captures up to 96% of the CO2 contained in the exhaust gas from natural gas turbines used to drive turbo compressors, even when the CO2 concentration is less than 3% and the exhaust gas is at low pressure. The technical knowledge gained through this project is expected to be applied to CO2 capture from other exhaust gas sources with similarly low CO2 concentrations.
The commencement of operation of this plant is not only an important step in the decarbonization of the industrial sector, but also a major step forward for the Ravenna CCS project promoted by Eni and Snam. The CO2 captured by this plant will be transported by pipeline and injected into Eni’s Porto Corsini Mare Ovest depleted gas field, located on the ocean floor at a depth of approximately 3,000 meters. This gas field is expected to store up to 4 million tons of CO2 per year by 2030.
Mitsubishi Heavy Industries has declared that it will achieve carbon neutrality by 2040, strategically focusing on decarbonization on both the energy demand and supply sides. One of the key pillars of this strategy is the construction of a CCUS value chain to connect CO2 emission sources with storage and utilization. Through this initiative, the company aims to contribute to global greenhouse gas reductions and environmental protection.

About Mitsubishi Heavy Industries’ CO2 Capture Technology
Since 1990, Mitsubishi Heavy Industries, in collaboration with Kansai Electric Power Company, Inc., has developed the CO2 capture technologies KM CDR Process™ and Advanced KM CDR Process™. As of September 2024, 18 plants utilizing these technologies have been delivered. The Advanced KM CDR Process™ employs KS-21™, a technologically improved version of the amine absorption liquid KS-1™. KS-21™ offers superior regeneration efficiency and reduced deterioration compared to KS-1™, with enhanced energy-saving performance, lower operating costs, and lower amine emissions.
