未来几十年，必须大幅减少温室气体排放，以使国际社会能够避免人为造成的全球变暖的最危险后果。这一事实反映在2018年通过的德国第七个联邦能源研究计划(EFP)中。用于从大气中吸收二氧化碳(CO2)的直接空气捕获(DAC)技术是实现这些温室气体减排的一种方法。DAC已被确定为仍存在重大技术差距的技术(组)。本文的目的是通过多维分析来探索DAC对EFP的潜在作用，展示该技术对德国政府能源和气候政策目标的可能贡献，以及对德国工业在现代能源技术领域的全球声誉的贡献，以及将DAC整合到现有能源系统的可能性。研究结果表明，DAC未来的作用受到多种不确定性因素的影响。该技术仍处于早期开发阶段，尚未证明其大规模技术可行性以及经济可行性。多维评估的结果，以及进一步技术开发、综合评估和系统级分析的必要性，证明了将DAC技术纳入EFP等国家能源研究计划的合理性。
A significant reduction in greenhouse gas emissions will be necessary in the coming decades to enable the global community to avoid the most dangerous consequences of man-made global warming. This fact is reflected in Germany’s 7th Federal Energy Research Program (EFP), which was adopted in 2018. Direct Air Capture (DAC) technologies used to absorb carbon dioxide (CO2) from the atmosphere comprise one way to achieve these reductions in greenhouse gases. DAC has been identified as a technology (group) for which there are still major technology gaps. The intention of this article is to explore the potential role of DAC for the EFP by using a multi-dimensional analysis showing the technology’s possible contributions to the German government’s energy and climate policy goals and to German industry’s global reputation in the field of modern energy technologies, as well as the possibilities of integrating DAC into the existing energy system. The results show that the future role of DAC is affected by a variety of uncertainty factors. The technology is still in an early stage of development and has yet to prove its large-scale technical feasibility, as well as its economic viability. The results of the multi-dimensional evaluation, as well as the need for further technological development, integrated assessment, and systems-level analyses, justify the inclusion of DAC technology in national energy research programs like the EFP.
