Italgas and Buzzi Unicem sign power to gas agreement

Italgas and Buzzi Unicem have signed an agreement for the development of a feasibility study on the implementation of Power to Gas plants in combination with carbon capture systems at Buzzi Unicem's cement production plants. 

The implementation of these technologies is aimed at promoting the decarbonisation of cement and concrete production processes to increase environmental sustainability and facilitate the energy transition. In particular, the study will assess the possibility of producing and using, in the most suitable Buzzi Unicem plants, synthetic methane obtained from the combination of green hydrogen produced by the Power to Gas plants with part of the CO₂ released in the production processes.

Luigi Buzzi, Group Technical Director at Buzzi Unicem, confirms that: "we are very interested in the opportunity to collaborate with Italgas as an experienced partner to develop a project that is fully integrated into our industrial investment plan aimed at identifying technologies for capturing and reusing the CO₂ released by our plants, in line with the roadmaps defined by industry associations. 

“Our aim is to responsibly contribute to containing climate change by developing CO2 capture technologies and identifying the best solutions for its reuse. We are currently experimenting with Calcium Looping technology for capturing the carbon dioxide released by the production process at our plant in Vernasca (PC). Thanks to the EU Horizon 2020 project "CLEANKER" (CLEAN- clinKER), it will be possible to assess the technical and economic sustainability of this technology and estimate the changes to the plant and the investments required to adopt this process in existing cement plants.”
