To date, all commercial CO2capture plants use processes based on chemical absorption with a monoethanolamine (MEA) solvent. MEA was developed over 60 years ago as a general, non-selective solvent to remove acid gases, such as CO2and H2S, from natural gas streams., The electrochemical reduction of carbon dioxide, also known as CO2RR, is a process that converts carbon dioxide (CO 2) to more reduced chemical species using electrical energy. CO2RR can produce diverse compounds including formate, carbon monoxide, methane, ethylene, and ethanol. [1] Provided the process is run using renewable energy and the CO 2 is sourced from flue gas or direct air capture , Here, we review adsorption technologies for carbon dioxide capture with focus on materials, techniques, and processes, additive manufacturing, direct air capture, machine learning, life cycle assessment, commercialization and scale-up., Opportunities and upcoming challenges of solid CO 2 adsorbents are discussed. Current modification strategies and research directions for selected CO 2 capture materials are summarized. The extensive collection of performance data on solid adsorbents for CO 2 capture efficiency is presented., A new way of removing carbon dioxide from a stream of air could provide a significant tool in the battle against climate change. The new system can work on the gas at virtually any concentration level, even down to the roughly 400 parts per million currently found in the atmosphere., (Bi)carbonate salt formation has been widely recognized as a primary factor in poor operational stability of the electrochemical carbon dioxide reduction reaction (CO2RR). We demonstrate that flowing CO2 gas into an acid bubbler—which carries trace .
