Direct Air Capture (DAC) is gaining momentum as a crucial tool in mitigating climate change. This technology involves extracting carbon dioxide (CO₂) directly from the atmosphere and storing it safely underground. Recent developments have significantly improved DAC's efficiency and scalability. For instance, Climeworks' "Mammoth" facility in Iceland, inaugurated in May 2024, can capture up to 36,000 tons of CO₂ annually. This advancement is made possible by integrating renewable energy sources, such as geothermal power, which not only reduces operational costs but also minimizes the carbon footprint of the capture process. en.wikipedia.org
The economic feasibility of DAC has also seen improvements. Collaborations between industry leaders and research institutions have led to the development of advanced materials and processes that lower energy consumption and costs. Notably, electrochemical methods have reduced energy requirements to as low as 1,055 kWh per ton of CO₂ captured. Additionally, economies of scale achieved through bulk purchasing and streamlined manufacturing processes have lowered DAC modules' per-unit cost. Financial incentives and supportive policies, such as the 45Q tax credit in the United States, further enhance the economic feasibility of these technologies. sciencedirect.com
