SolarEV City concept in Paris and Ile-de-France: a promising idea? Deroubaix P., T. Kobashi, L. Gurriaran, F. Benkhelifa, P. Ciais, K. Tanaka



Since the Paris Agreement adopted in 2015, global societies are increasingly aware of the needs to limit global warming to 1.5 ï‚°C and reach global carbon neutrality by 2050. However, current commitments of global societies are not sufficient, party owing to the lack of cost-effective decarbonization measures. The SolarEV City concept is proposed for cost-effective urban decarbonization combining rooftop PV with EV through bi-directional charging in a city scale. In this study, we conducted techno-economic analyses to test the concept in Paris and Ile-de-France. PV+EV systems are found to add value to rooftop PV systems raising self-consumption and self-sufficiency, when the roof coverage by PV is reached to 50-60% for Paris and 20-30% for Ile-de-France, allowing to bypass expensive stand-alone battery storage. The system allows CO2 emissions reduction through accelerated development of EV.
