Sumitomo SHI FW to deliver carbon capture demo plant

Sumitomo SHI FW to deliver carbon capture demo plant
At the a2a Ambiente Milan Silla-2 waste-to-energy (WtE) plant, Sumitomo SHI FW (SFW) will install a demo unit of its proprietary CaL carbon capture technology as part of the EU-funded HERCCULES project. On an annual basis, the Milan Silla-2 facility processes around 550 000 tonnes of municipal solid waste (MSW) to supply 480 GWh of heat and 290 GWh of electricity (photo courtesy a2a).

Sumitomo SHI FW (SFW), a subsidiary of Japan-headed Sumitomo Heavy Industries Ltd (SHI) has announced that it will supply its proprietary Calcium Looping (CaL) carbon capture technology to a demonstration plant in Italy as part of the recently started EU-funded HERCCULES project.

Carbon capture technologies are vital for reaching carbon neutrality by 2035. Launched at the beginning of 2023, the EU-funded project HERCCULES aims to demonstrate Carbon Capture, Utilization, and Storage (CCUS) value chains.

The captured carbon dioxide (CO2) in the project will be delivered to two permanent storage sites in Italy and Greece.

Demo Calcium Looping

The focal technology for the HERCCULES project, Calcium Looping (CaL), is developed by Sumitomo SHI FW (SFW) which is also a partner in the project.

The technology will deliver a solution to match the decarbonization objectives of the hard-to-abate industrial sectors, leveraging SFW’s extensive experience of delivering over 800 commercial fluidized bed (FB) plants.

SFW has traditionally developed, designed, and delivered combustion systems for industry and power plants, including waste-to-energy plants. Today, SFW is focused on providing solutions for the decarbonization of industries that have high carbon dioxide emissions, including cement, steel, and power, said Edgardo Coda Director of R&D at SFW.

Flexible solution

In the HERCCULES project, CaL creates added value for industrial plant operators in the form of circular economy applications, decarbonizing energy generation, and enabling sector coupling opportunities.

In an essence, CaL addresses Scope 1, 2, and 3 emissions throughout the value chain.

CaL is a flexible solution to capture more than 90 percent of emitted CO2while providing synergy with green hydrogen plants. Biogenic CO2can be directed for low-carbon fuel and material production where the by-product oxygen is used to capture CO2. The solution also generates green electricity and lime as by-products, said Mohamed Magdeldin, Director of Carbon Capture at SFW.



The HERCCULES project has the combined strength of 23 partners from nine European countries and is being funded by the European Union (EU) under the Horizon Europe program.

The five-year project aims to demonstrate the feasibility of the entire carbon dioxide (CO2) Capture, Utilisation, and Storage chain (CCUS) in the regions of southern Europe with a high industrial density, in this case in the Po Valley and Greece.

The primary focus is the decarbonization of cement production and waste-to-energy (WtE), two strategic sectors for the circular economy.

Under the coordinator LEAP – Piacenza Energy and Environment Laboratory (Italy), consortium members include EU CORE Consulting (Italy), Energan Oil&Gas (Greece), Buzzi Unicem (Italy), Titan cement (Greece), Sumitomo SHI FW (Finland), Air Liquide (Italy), Fraunhofer ISI (Germany), Politecnico di Milano (Italy), BCG (Italy), CSIC (Spain), Celitement (Germany), Università di Utrecht (The Netherlands), Wietersdorfer Alpacem (Austria), Artidek (Ukraine), Shogenergy (Estonia), Università di LUT (Finland), TPI (Italy), ClustER Greentech (Italy), CRES (Greece), a2a Ambiente (Italy), a2a S.p.A (Italy), and Eni S.p.A (Italy).

To be installed at Milan Silla-2 WtE plant

The CO2capture plant will be installed at the Milan Silla-2 waste-to-energy plant, owned and managed by a2a Ambiente, a member of a2a S.p.A, an independent multi-utility major.

The plant is one of the largest waste management facilities in Italy and the combined heat and power (CHP) plant processes around 550 000 tonnes of municipal solid waste (MSW) and non-hazardous special waste annually.

The demo plant will operate for up to 4 000 hours and conclude with commercial-scale activities.

SFW will adapt the plant design to optimize performance and footprint specific to the site conditions. The delivery will include the commissioning, operation, and training of the facility personnel.

此外,氧化钙(曹)副产品from the demo will be collected and sent to act as a low-carbon raw material in cement and concrete manufacturing.

a2a’s goal is to reach Net Zero by 2040. To achieve this goal, a2a is engaged in various research activities aimed at identifying and developing the most promising technologies for carbon capture utilization and storage. a2a chose to work with SFW’s Calcium Looping technology as we believe that it can play an important role in our decarbonization process, said Adriano Carrara, Progam Manager CCUS R&D at a2a.
