a critical review on membrane technology and its application in co₂ capturing

Co2 emission resulting from rapid urbanization and industrialization is a significant contributor to global climate change, resulting from the burning of fossil fuels such as coal, oil, and natural gas. approximately two billion tons of co2 are released annually by all of the coal-fired power plants that are still in operation today. various strategies that have been implemented to reduce co2 emissions includes energy efficiency, renewable energy, carbon capture and storage. membrane technology has emerged as a promising solution for co2 capture and is currently being investigated for co2 capture from power plant emissions due to their fundamental engineering and cost effectiveness over competing separation technologies. this technology involves the use of selective membranes that allow the separation of co2 from gas mixtures such as flue gas, natural gas, and biogas. the performance of the membranes can be enhanced through the use of advanced materials, surface modification, and process optimization. the aim of this study is to review the literature on the recent advancements made in membrane technology and its application in reducing co2 emissions from the past few years.
