Emerging towards zero carbon footprint via carbon dioxide capturing and sequestration

Concerns about climatic changes and global temperature enhancements have sparked efforts worldwide to curb the magnitude of atmospheric carbon dioxide. A key tactic for achieving carbon dioxide emission mitigation goals is Carbon dioxide capturing and sequestration, which is critical for the seamless changeover from the prevailing fossil-based power systems to more eco-friendly future energy systems. Among the carbon dioxide capturing techniques, post-combustion capture is the most practical method for retrofitting existing power plants although it result with 3-15 vol.% concentrated carbon dioxide gas stream. Chemical looping combustion captur-ing receives much attention receives much attention owing to its non-pollution nature and the yielding of highly concentrated carbon dioxide stream, up to 100%. This review also explores a variety of sequestration strategies, including geological carbon dioxide sequestration with multiple geological carbon dioxide storage sinks, mineral carbonation sequestration, as well as marine sequestration. The carbon dioxide transportation and the storage facilities comprising pressure vessels, pipelines, and cryogenic storage tanks are also discussed briefly. The En-hanced gas recovery, Enhanced water recovery, and Enhanced oil recovery, which rely on geologically stored carbon dioxide are also taken into account in this analysis as a part of the commercial-economic application of carbon dioxide capturing and sequestration. Along with the risk considerations related to the sequestration pro-cesses, the efficient exploitation of the sequestered carbon dioxide is delineated as a road map leading to future prospects. Concerns have been raised that the widespread adoption of carbon dioxide capturing and sequestra-tion will likely be affected by the general public perceptions due to unawareness, along with potential leakage risks and the enormous capturing cost, which should be puzzled out for the effective uptake of carbon dioxide capturing and sequestration strategies.
