Sumitomo SHI FW to deliver another carbon capture demonstration plant at a2a’s waste-to-energy facility

Carbon capture technologies are vital for reaching carbon neutrality by 2035. Launched at the turn of this year, the EU funded project HERCCULES demonstrates the utility of Carbon Capture, Utilization, and Storage (CCUS) solutions. The CO2 captured in the project will be delivered to two permanent storage sites in Italy and Greece. ​

The focal technology for the HERCCULES project, Calcium Looping (CaL), is developed by Sumitomo SHI FW (SFW). The technology will deliver a solution to match the decarbonization objectives of the hard-to-abate industrial sectors. SFW's mission is to power a decarbonized world for everyone, leveraging the company’s extensive experience of delivering over 800 commercial fluidized bed 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.

SFW’s Director of R&D

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% of emitted CO2 while providing synergy with green hydrogen plants. Biogenic CO2 can 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.
Mohamed Magdeldin
SFW, Director of Carbon Capture

The CO2 capture plant will be installed at the Milan Silla-2 waste-to-energy plant, owned and managed by a2a Ambiente, a member of the a2a group. The plant is one of the largest Italian waste management facilities that handles around 550 000 tons of municipal solid waste and non-hazardous special waste per year. 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. In addition, the calcium oxide by-product 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,
