We provide a perspective on the development of direct air capture (DAC) as a leading candidate for implementing negative emissions technology (NET). We introduce DAC based on sorption, both liquid and solid, and draw attention to challenges that these technologies will face. We provide an analysis of the limiting mass transfer in the liquid and solid systems and highlight the differences.

观点 - 负排放技术的需求和前景 - 通过当前吸附过程开发的镜头直接空气捕获

我们对直接空气捕获 (DAC) 作为实施负排放技术 (NET) 的主要候选者的发展提出了看法。我们介绍基于液体和固体吸附的 DAC，并提请人们注意这些技术将面临的挑战。我们对液体和固体系统中的极限传质进行了分析，并强调了差异。
