Italian energy companies Italgas and Buzzi Unicem have joined forces to promote decarbonisation of cement and concrete production processes through the use of Power to Gas plants and carbon capture systems.

Cement production is associated with 8% of total carbon dioxide (CO) emissions worldwide, making its decarbonisation a key component of a successful energy transition. 

The agreement will focus on assessing the possibility of producing and using synthetic methane created sustainably through green hydrogen produced by the power-to-gas plants. 

Some of the CO2 emitted during the production process of the green hydrogen will also be used to produce the synthetic methane. 

Italgas sees the production of hydrogen from renewable sources as an enabler of gas networks to be used in a ‘dual function’ capacity as both a carrier and energy storage asset. 

Paolo Gallo, CEO, Italgas, added, “The agreement represents a great opportunity for us to take a further step forward in the study of innovative solutions and technological best practices.” 

The company has previously been involved with the development of a power to gas project in Sardinia to produce green hydrogen for public transport and local industry. 

Buzzi Unicem see the CO2 capture component as being essential to containing climate change, with Luigi Buzzi, Group Technical Director, saying, “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 CO2 released by the production process at our plant in Vernasca.”
