The Chemistry of Carbon Capture: Techniques and Challenges in Reducing Greenhouse Gas Emissions

Abstract

One of the main causes of climate change and global warming is emissions of carbon dioxide (CO2), hence carbon capture and storage (CCS) technology is essential for reducing these effects. chemical aspects of carbon capture, with an emphasis on the numerous methods that are employed to extract CO2 from both ambient air and industrial emissions. Chemical solvents, adsorbents, and membranes are utilised in these methods to isolate CO2, which comprise oxy-fuel combustion procedures, post-combustion, and pre-combustion. promising new ways to remove CO2 on a massive scale, including biological technologies and direct air capture (DAC). Numerous obstacles, including as energy demands, cost, scalability, and long-term storage stability, remain in the way of the broad use of CCS, notwithstanding the technical advances. In addition, we cover topics including legislative and regulatory frameworks, social and environmental acceptability, and more. Through an analysis of these methods and obstacles, we may better understand carbon capture's potential as an important tactic in the worldwide fight against climate change and the reduction of CO2 emissions.
