For renewable energy to be utilized at the plant, stationary pure hydrogen fuel cells with a rated power output of 3.5 kW have been installed. Additionally, an energy management system that combines solar power generation with storage batteries made by recycling used batteries from Prius hybrid vehicles has been put into operation.

With this system, energy demand from the energy management facility is being projected, and a corresponding efficient energy supply is realized mainly through the highly energy-efficient fuel cells. These are supplemented by solar power―which generates changeable supply of power, in combination with storage batteries. The excess thermal energy generated by the fuel cells is then used for air-conditioning.

Working toward zero CO2 emissions through these initiatives, Toyota will also carry out technology development and testing with the aim of minimizing CO2 emissions from the building's operation. The pure hydrogen fuel cells with rated power output of 3.5 kW that have been installed are a model newly developed for use in small offices. This project represents the first operational start within a commercial environment.

While monitoring the results of the installation and testing of the pure hydrogen fuel cells, Toyota will progress with the development and installation of efficient hydrogen utilization technology at the plant's other buildings, thus moving steadily forward with initiatives to realize zero CO2 emissions.
