A Cost-Benefit Analysis for Extraction of Atmospheric Water by Direct Cooling in South Korea

초록

In this study, the aim is to first determine the atmospheric water potential, as a sustainable water resource, in the six major cities of South Korea. Thus, a cost-benefit analysis was performed to assess the economic feasibility of atmospheric water in three scenarios: Inbound, Outbound, and Hybrid. The findings from the empirical results show that all six South Korean cities had a positive net present value (NPV) less than a year after the use of air water generator (AWG) devices in Inbound and Hybrid scenarios. Finally, considering the drinking capacity of atmospheric water, this study examined the potential reduction in CO2 emissions through a reduced consumption of water bottles. The results show that using a single AWG device will reduce on averagethe consumption of 5421.5-liter water bottles in a five-year period , equivalent to 135.76 Kilograms of GHG emission reduction.
