Abstract

The major objective of this research is to support future-proof applications of rooftop photovoltaics (PV) and electric vehicles (EV) as batteries for urban decarbonization. Although extensive research has been conducted, the feasible pathways have often been limited due to the complexity of analyzing interdependencies of energy, environment, and cost effects as well as a lack of sectoral analysis for cities which could offer stepwise application strategies. Therefore, this research conducted techno-economic analyses for rooftop PV + EV with respect to multiple cities in South Korea using System Advisory Model (SAM), and different building sectors in Seoul using MATLAB. The results showed that CO2 emissions can be reduced about 49% when applying rooftop PV combined with EV in Seoul in 2030. The results also indicate that the investment of PV and EV in residential buildings should be prioritized in Seoul. This research will contribute to providing decarbonization pathways for Korean cities, and ultimately alleviating global warming.
