Toyota Motor Corporation will begin to sell fuel cell buses (FC buses) under the Toyota brand from early 2017. After repeated field tests of the hydrogen-powered buses for practical use, the Bureau of Transportation of the Tokyo Metropolitan Government plans to utilize two of the Toyota FC Buses as fixed-route buses.
Toyota plans to introduce more than 100 FC buses mainly in the Tokyo area, ahead of the Tokyo 2020 Olympic and Paralympic Games. In view of this, the FC buses will be sold for the first time in Japan in early 2017, so as to help increase the level of understanding by the general public of the utilization of FC buses as a form of public transportation.
Moreover, in preparation for the Tokyo 2020 Olympic and Paralympic Games, the number of FC buses being introduced will increase steadily going forward. Together with this, Toyota aims to engage continuously in the development targeted at the expansion of the introduction of the new FC buses from 2018.
The Toyota FC Bus was developed by Toyota, based on the company's experience in developing FC buses together with Hino Motors, Ltd. (Hino). The Toyota Fuel Cell System (TFCS)—which was developed for the Mirai fuel cell vehicle (FCV)—has been adopted to provide better energy efficiency in comparison with internal combustion engines, as well as to deliver superior environmental performance with no CO2 emissions or substances of concern (SOCs) when driving.
The bus also can function as a high-capacity external power supply system. With a power supply capable of a 9 kW maximum output, and a large capacity of electricity supply at 235 kWh, the FC bus can be used as a power source in the event of disasters, such as at evacuation sites such as in school gymnasiums or for home electric appliance use.
