Yamabiko Corporation (“the Company”) and MIRAI-LABO Co., Ltd. (head office: Hachijoji, Tokyo. President & CEO: Toshio Hiratsuka) recently embarked on a joint demonstration experiment aimed at the development of a hybrid autonomous energy system. On December 24, 2021, the Company signed a capital and business alliance contract with MIRAI-LABO, and until date we have been studying the development of a hybrid autonomous energy system that leverages the technologies of both companies. To verify the validity of this system, the Company installed a small-scale experimental facility on the roof of its head office and began a demonstration experiment.

1. System structure On the roof of the Company's head office, we installed solar panels and the G-CROSS refillable-battery generator (G-CROSS for short) made by MIRAI-LABO along with the Company's generator equipped with a remote supervision device. (Photo 1) The power generated by the solar panels is supplied to G-CROSS. However when the amount of generated energy supplied drops due to bad weather, or when the amount of power used increases and the battery's capacity drops below the stipulated level, G-CROSS transmits a signal which causes the Company's generator to operate automatically to supply power. This provides a stable supply of power at all times regardless of changes in the environment or amount of power used. The basic system structure is as shown in the image below. (Image 1)
   
2. Demonstration experiment During the demonstration experiment for this system, we are causing fluctuations in the amount of power used and checking whether the system could constantly provide a stable supply of power. Furthermore, the Company is also checking the operating status of our generator using a remote supervision device, the technology for which has already been established, and continuously monitoring information such as the amount of power generated by the solar panels and the capacity of G-CROSS. (Photo 2, Image 2) We are also using biofuel to operate the Company's generator, making it a hybrid autonomous energy system that contributes to carbon neutrality.
   
3. Future developments Through this demonstration experiment, we will advance our research into locally-produced and locally-consumed microgrids that use renewable energy, and promote decarbonization.
