Abstract
Energy transition will not be abrupt but slow till we find sustainable energy resources for the mankind. In view of increasing global warming and CO2 emissions, immediate actions are required to address these issues, which may involve storing large amounts of anthropogenic CO2 in geological and oceanic repositories. In terrestrial storage sites, CO2 tends to rise due to the underground temperature profile. Therefore, if the reservoir is not properly sealed, stored CO2 can escape from geological formations. On the other hand, oceanic sequestration holds great potential for long-term CO2 storage beneath the seabed, supporting the broader scientific and industrial community in achieving carbon neutrality. Subsea CO2 sequestration holds significant promise for ensuring stable, long-term CO2 storage and, consequently, can make a substantial contribution to achieving global carbon neutrality and mitigating the challenges of global warming. However, several key factors at the macroscopic level, including salinity, sediment porosity, sedimentary types, and the use of additives, are essential in realizing the full potential of subsea CO2 sequestration. A deeper understanding of the chemical interactions among CO2, hydrate-bearing sediments, additives, and marine environments is crucial for comprehending hydrate formation within subsea sediments. These dimensions offer a vast landscape for discussion, paving the way for future technological innovations. Consequently, there exists a broad scope for discourse in this field that will drive the development of novel technologies in the years to come.
