The present paper presents the results obtained in a three-year natonal research project on natural gas hydrate exploitaton and carbon dioxide disposal. The consortum of partners is led by University of Perugia (UNIPG), which includes the Applied Physics group and the Structural Geology group. The other partners are the University of Camerino (UNICAM), the Politecnico di Torino (POLITO), the Isttuto di Oceanografa e Geofsica Sperimentale (OGS) and the University of Ferrara (UNIFE). The proposed project aims to develop an innovatve technological soluton for the extracton of methane from marine natural gas hydrates and the simultaneous sequestraton of carbon dioxide in a single process (Fig. 1; Gambelli et al., 2021). The obtained fuel is neutral in terms of climate changing emissions and therefore equivalent to renewable energy sources. The multdisciplinary expertse of the consortum is focussed on the pursuit of fve specifc objectves: 1. Analysis of marine hydrate reservoirs, potentality and infrastructures for their exploitaton 2. R eproducton of hydrate sediments in the laboratory and determinaton of kinetc and thermodynamic parameters 3. CO2 replacement in methane hydrates 4. Development of a scalable technology for CO2 injecton/CH4 extracton in natural hydrate reservoirs 5. Theoretcal model applicable of marine hydrate reservoir and energy/environmental assessment of the proposed process.
