Climate technology investment and innovation: Potential benefits of CO₂ capture from the air

The purpose of this paper is to provide insights into technological innovation and investment for CO₂ reduction with focusing on the concepts of carbon capture and storage (CCS) and CO₂ direct air capture (DAC) technology. The paper initially argues the necessities and motivations for technology innovation as an effective approach for addressing climate change problem. Then, it undertakes investigations to track the main features, technical progresses, and potential benefits of CO₂ air capture over conventional methods. Finally, economical aspects and cost feasibility issues associated with this technology are discussed. The study approves air capture as an effective and feasible investment for climate change mitigation, subject to extensive commitments and strong policy supports.
