As a way to mitigate climate change, reducing greenhouse gas emissions from specific emission sources has been the focus of most research. Recently, however, increasing attention has been paid to a carbon dioxide removal approach that removes greenhouse gases from the atmosphere. While this approach utilizes diverse technologies, this paper focuses on direct air carbon capture and storage (DACCS) technologies. This technology is being considered as one of the mitigation options by governments and private sectors in several developed countries. Direct air capture (DAC) technology is also included in Korea’s 2050 carbon neutrality scenario. Yet, DAC technology, which is related to DACCS technology, has a very small stake in that scenario. Furthermore, Korea has never undertaken R&D projects on DACCS technologies. Although some R&D projects have been conducted in Korea with yielded results, they were on general carbon capture, utilization and storage (CCUS) technologies, not directly dealing with DACCS. Therefore, this paper attempts to explore Korea’s R&D potential for DACCS, focusing on DAC technologies, for DACCS technology deployment in Korea to meet the national mitigation target. In this regard, this paper questions whether the current research capacities of Korea are compatible with those required for DACCS technologies. From previous literature on three factors that influence the deployment of DACCS technologies, i) technological factors, ii) economic factors, and iii) environmental factors, this paper formulated an analytical framework with four technological factor components: i) capture materials, ii) capture process, iii) required (input) energy, and iv) carbon credits from technology project implementation. This paper analyzes current Korean R&D capacity in these four components and draws recommendations for future policy. KCI Citation Count: 0
