A Circular Approach to Upgrade Cement-based CO2 and Renewable H2: Techno-economic Analysis of SNG Production

The present work introduces a feasible, carbon-free integrated process that is based on the catalytic hydrogenation of industrially captured CO2 via green H2 towards the production of synthetic natural gas (SNG). Overall, three systems are being assessed from an economic point of view (sizing and si...
