ANALYSIS OF 100% RENEWABLE ENERGY SCENARIO IN TOKYO METROPOLITAN AREA WITH GREEN RECOVERY BY 2050

抄録

This study presents investigation of the possibility of 100% Renewable Energy Scenario in Tokyo metropolitan area with green recovery process by 2050. In the Zero Emission Tokyo Strategy, the Tokyo Metropolitan Government aims to decarbonize 100% of its energy use by 2050 to achieve net zero CO2 emissions by using renewable energy as main energy sources and strengthen energy efficiency. To achieve this goal, a scenario for 100% renewable energy in Tokyo is examined, which corresponds to a sustainable economic recovery so called green recovery from the COVID-19, and the potential for energy conservation and the possibility of energy conversion through sector coupling are shown. The amount of renewable energy introduced in Tokyo will be increased as much as possible in consideration of its potential for introduction in the area, and mainly solar and wind power electricity will be procured from outside the area. Electrification for the use of renewable energy electricity will be promoted, but the use of renewable heat and hydrogen and green gas/fuel from surplus electricity in the region is also envisioned.
