My research interests are primarily focused on developing new sustainable energy systems on the grounds of a strong engineering approach, with particular attention on transferring the application from lab/theory to industrial-relevant size. Process synthesis, system integration and performance evaluation are based on first principle theoretical models and computer simulations, which are complemented with test rigs and experimental validation whenever possible.
Looking at the research activity on energy, three main areas of investigation stand out: (i) fundamental research on new materials, (ii) process development and process intensification and, iii) system integration and optimization. Indeed, most of the efforts are primarily focused on the first category as it implies great advancements and technical breakthroughs. However, simple analyses based on the material properties are often conducive to the overestimation of the performance. As a result, only a limited number of the proposed new materials reaches the commercialization phase. For example, the number of materials used in commercial adsorption, membrane or catalytic-based processes is very limited compared to what is found in the open scientific literature. In order to achieve tangible improvements in the energy system area, there is the need of considering: (i) the overall energy requirement of the process, and (ii) the real working conditions (e.g. temperature, impurities, multi-component behavior). Therefore, I believe that a comprehensive methodology for new materials and technology assessment is key.
Following my research background, I am primarily interested in modelling and developing innovative solutions for power production, both at centralized and decentralized scale, and energy-intensive industry processes (refineries, iron and steel, chemical productions). The final goal is to develop and improve efficient energy systems while keeping in mind the current technology level.
My research focus on the following three pillars:
The application of CO2 capture technologies is an essential element for the achievement of carbon neutrality by 2050, based on the scenarios outlined in the European directives and in the recommendations of the Commission itself. In Europe, there are today about 70 CCUS (Carbon capture, utilization, and storage) projects at various stages of development, concentrated almost exclusively in the Northern countries. In this framework, HERCCULES aims at defining a first-of-a-kind, integrated and replicable approach for the implementation of the whole CCUS chain to two strategic sectors of the circular economy - Cement and Energy-from-Waste (EfW) – in an area – Italy and Greece – where the industrial promise of CCUS is largely unexplored. Leveraging on the potential of two clusters of emitters in Northern Italy (cement + EfW) and Greece (cement), HERCCULES will pave the way towards the implementation of the first full-scale CCUS chain in Southern Europe.
Over 9,000 hours of testing will be dedicated to demonstrating innovative CO2 capture processes installed in two cement plants. The experimental plants will be based on advanced oxy-combustion and post-combustion capture technologies such as Calcium Looping combined with cryogenic purification processes, capable of separating CO2 with efficiencies and purities close to 100%. Part of the pure CO2 flow will be used in mineralization processes for new cementitious materials production that could replace conventional concrete (characterized by a high carbon footprint).
The activities will also include the transport of CO2 from the industrial capture sites to the two geological storage sites at Ravenna (in Italy and Prinos in Greece, to complete the demonstration of the entire CCUS supply chain.
The technological, infrastructural, safety, regulatory, and financial aspects will be addressed with a multidisciplinary approach, which will allow the creation of industrial communities capable of exploiting the synergies between the processes of the CCUS supply chain. Universities, research centers, and consulting companies will develop business models of HERCCULES technologies sized for future full-scale applications.
Matteo Gazzani leads the workpackage on full CCS chain integration and optimization
As the only technology that can substantially reduce CO2 emissions from fossil fuels and industrial processes, CCS is an essential component in the vast majority of IPCC scenarios with a likely global global warming of 2°C or less. Indeed, without CCS, it will be extremely difficult to keep the rise in global temperature within the limits set by the Paris Agreement. Yet there is a large disconnect between policy ambitions and technology readiness – and industrial uptake. This is mainly due to the lack of a business model: costs are immediate, but the benefits are long term.
