Abstract 

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. The review investigates the complexities of DAC implementation, examining real-world case studies and pilot projects to extract valuable insights into operational challenges, successes, and lessons learned. Looking forward, the paper discusses future prospects and research directions within the DAC landscape. It explores emerging technologies, the integration of DAC with carbon utilization strategies, and the importance of collaborative initiatives and international cooperation. The abstract concludes by summarizing key findings, emphasizing the implications for climate change mitigation, and issuing a call to action for policymakers, researchers, and stakeholders to collectively address challenges and advance the deployment of DAC technologies. This comprehensive review aims to contribute to the evolving discourse on carbon removal strategies by providing a holistic and up-todate analysis of DAC technologies, paving the way for informed decision-making and accelerating progress toward achieving global carbon reduction goals.
