    Building up a low-carbon society has become one of the world’s common challenges. ‘Power to Gas’ efforts – to convert electric power derived from renewable energy into hydrogen – are being actively conducted, mainly in Germany. Similar efforts are

    being made in Japan. For example, concerned Japanese cabinet members agreed on a ‘ Hydrogen basic strategy ‘ on Dec. 26 2017. This strategy, with a view to 2050, shows direction and vision toward the realization of a hydrogen society and compiles an action plan to achieve that goal. It aims to scale up hydrogen consumption volume from 0.4 ten thousand t (2020) to 30 ten thousand t (2030) and deduct the unit price of hydrogen from ¥100Nm3 (now) to ¥30Nm3 (2030).We will also try to construct a preliminary autonomous energy system using regenerative energy. In this paper, the operation and function of such a system is described.

    In this research, with the installation of Sigfox’s antenna in our university, we installed IoT equipment that makes use of the Sigfox network. As an example of an IoT device, we tried installing it on a water meter to acquire data, such as water usage fee, via internet. Also, using the system outline, we constructed it as an educational system.
