Despite the technical viability and maturity of the conventional processes, the energy penalty associated with carbon capture (CC) is still significantly higher than the thermodynamic minimum . Especially at low mixing ratios, up to 30% of a fossil-fueled power plant's energy is required for capturing CO 2 from a flue gas . Hence, for many applications, the conventional processes are economically not feasible . Consequently, significant research and development efforts are ongoing investigating unconventional methods such as chemical looping combustion , algae-based CC , and hybrid methods . Amid these methods, hydrate-based carbon capture (HBCC) has been gaining increased attention due to its potential for economically feasible and large-scale CO 2 separation . This can be attributed to several factors.
