Hydrate based carbon capture and sequestration (HBCCS): An innovative approach towards decarbonization

Abstract

The surge in global greenhouse gas emissions (mainly CO2) has introduced the world to the significant problem of climate change. A paradigm shift towards sustainable energy sources is necessary to meet the sustainable development goals (SDGs). Applying carbon capture and sequestration (CCS) technologies could be a suitable approach for minimizing anthropogenic CO2. Implementation of CCS involves enormous capital expenditure along with transportation, sequestration, and purification cost making its adaptability economically unfeasible. A novel approach to hydrate-based CO2 capture and sequestration (HBCCS) has gathered significant attention due to its potential to provide long-term CO2 sequestration. Herein, the methane-carbon dioxide sweeping process (CH4-CO2 replacement) has gained considerable interest as it produces clean energy (natural gas) from natural gas hydrate deposits while sequestering anthropogenic CO2. In this review paper, we presented a thorough assessment of the HBCCS process while highlighting the critical factors along with the economic/environmental/technical barriers controlling its deployment in actual field applications.
