Recent progress on direct air capture (DAC) cost reduction is multifaceted, involving advancements in materials, processes, and supportive policy frameworks. A comprehensive review in *Energy & Environmental Science* appraises the state-of-the-art in DAC technologies, highlighting ongoing research into novel materials and processes that aim to lower the energy requirements and capital costs associated with capturing CO₂ directly from the atmosphere [2]. This review underscores the techno-economic challenges and the importance of sustainability and policy considerations in making DAC a more viable and scalable climate solution. Policy interventions, particularly in the United States, have played a significant role in driving down the effective cost of DAC and other carbon capture technologies. The expansion of the 45Q federal tax credit under the Inflation Reduction Act (IRA) has substantially increased financial incentives, including higher dollar values and the option for direct payment, which has spurred greater industry engagement and investment in carbon capture projects [3]. These policy enhancements are critical for bridging the gap between current high costs and the economic viability necessary for widespread deployment. While DAC technology remains expensive, the convergence of scientific innovation and robust policy support is creating a more favorable environment for cost reduction. The review in *Energy & Environmental Science* provides a foundational understanding of the technological and economic hurdles [2], while the analysis of the 45Q tax credit demonstrates how policy can directly influence the economics of carbon capture, accelerating progress toward more affordable direct air capture [3].
