Carbon Dioxide Separation Technologies: Applicable to Net Zero

Carbon dioxide (CO2) emissions from burning fossil fuels play a crucial role in global warming/climate change. The effective removal of CO2 from the point sources or atmosphere (CO2 capture), its conversion to value-added products (CO2 utilization), and long-term geological storage, or CO2 sequestration, has captured the attention of several researchers and policymakers. This review paper illustrates all kinds of CO2 capture/separation processes and the challenges faced in deploying these technologies. This review described the research efforts put forth in gas separation technologies. Recent advances in the existing gas separation technologies have been highlighted, and future directives for commercial deployment have also been outlined.
