Denryoku Sharing Co., Ltd. (D-Sharing; based in Shinagawa-ku, Tokyo; Chairman & CEO Naoki Sakai), which has a patented technology for meticulously measuring carbon dioxide (CO2) reduction and, thus, issuing granular renewable energy certificates, has been assisting Japan’s Ministry of Environment, for the last 6 years, inter alia, with a number of Randomized Controlled Trials (RTCs).
Electric Vehicles (EVs) are generally regarded as cleaner vehicles, emitting less CO2 compared with internal combustion engine (ICE) vehicles and would significantly contribute to decarbonization. However, Carbon Intensity (CI) of electricity used for charging EVs matters. If the CI of the charging electricity is 0 (zero), you can literally claim that your EV is carbon-free. On the other hand, if the CI of the charging electricity is high (e.g., in the evening when the power grid significantly needs to rely on fossil-fuel-fired thermal power plants), your EV may not be so clean. Also, as EV charging usually requires intense energy usage, it could potentially do a significant harm rather than contribute to decarbonization if done at a wrong time.
During this fiscal year, D-Sharing carried out a pilot RTC to encourage EV owners to charge their EVs during daytime when CI of electricity supplied from power grid is low under the collaborative framework of the “Daytime EV Charging Alliance (DECA)”. The effect of this time-shifting and balancing out demand and supply for smart decarbonization could be measured for the issuance of granular renewable energy certificates when relevant certification arrangements are put in place for officially creating proper incentives.
D-Sharing joined United Nations’ 24/7 Carbon-Free Energy Compact and intends to collaborate with UN by using, amongst other technologies and initiatives, the company’s patented technologies.
