This TECH report provides an overview of Direct Air Capture (DAC) technology and economics, as well as market aspects and climate landscape in terms of key policies and project status. This includes DAC technology process descriptions, key challenges and limitations, advantages and disadvantages, and areas for cost-reducing innovation. The report primarily focuses on sorbent- and solvent-based DAC approaches, with a minor focus on other developmental DAC methods such as moisture/humidity swing adsorption, cryogenic, electrochemical/electro-swing adsorption, and membrane-based DAC technologies. In addition, this report discusses key players and technology holders/licensors of DAC technology and includes base-case cost of CO2 capture estimates for sorbent- and solvent-based DAC processes.
