Negative Emissions Technologies

This paper will focus on Direct Air Capture (DAC), a type of Negative Emissions Technology (NET). Unlike other NETs, DAC allows for high storage permanence without the use of arable land or water sources, which minimizes impacts on agriculture and other land uses (Lebling et al., 2022). Additionally, the captured carbon can be used to create synthetic fuels,further reducing emissions (SFC Energy, n.d.). However, the main challenge of modern DAC is that it still requires additional funding to be deployed on a large scale. In addition, governments may be hesitant to provide the necessary funding because it is still not clear which NET would be the most prominent and profitable form of CO2 emission mitigation (Erans et al., 2022). Thus, to expand the deployment and bring DAC projects to fruition, more funding is required. This literary review focuses on the comparison between DAC and other negative emission technologies based on the process, benefits, risk, economics and efficiency in carbon capture. The goal of this project is to investigate direct air capture and illustrate its role and advantages in reducing the impact on climate change.
