As global concerns about anthropogenic climate change intensify, the imperative to mitigate carbon dioxide (CO₂) emissions has led to a growing interest in innovative carbon removal strategies. Among these, Direct Air Capture (DAC) technologies have emerged as a promising avenue for actively reducing atmospheric CO₂ concentrations. This comprehensive review seeks to provide a thorough examination of DAC technologies, encompassing their historical development, technical principles, and diverse methodologies. The review categorizes DAC technologies into chemical absorption methods, adsorption-based approaches, biological processes, and DAC with enhanced weathering, offering an in-depth analysis of each category. Technical assessments delve into the efficiency, scalability, and recent advancements within each DAC method, shedding light on the state-of-the-art developments in this rapidly evolving field. Challenges and opportunities associated with DAC are explored, encompassing technical hurdles, environmental considerations, and the evolving policy and regulatory landscape.
