Conventionally, the method of storing excess power at night as compressed air and extracting it as energy for power generation during peak power consumption was to set up an air storage tank on the seabed at a depth of about 200 to 300 meters, and use it to store the night power. The idea was to use a compressor to send compressed air from a compressor and store it, and then discharge this compressed air during peak power consumption during the day to turn a power generation turbine to generate electricity and supply electricity.

Since it is quite far from land, there was a problem in that it was difficult to tow and install the air storage tank.

According to the underground storage method and device for compressed air of the present invention described above, the air-filled bag is provided in a horizontal shaft excavated underground, so it floats up by buoyancy as in the case where it is installed on the seabed as in the past. There is no need to prevent air pollution, and since the air-filled bag is placed underground,
This has the advantage that underground space can be used effectively.
また、空気充填袋には、常時水圧が掛つている
ので、高圧の圧縮空気を貯蔵するのに、大きな強
度を必要としないという利点がある。 Furthermore, since water pressure is constantly applied to the air-filled bag, it has the advantage that great strength is not required to store high-pressure compressed air.
更に、従来のごとく空気貯蔵槽を海底に設置す

作業が不要であるので、従来例に比べてその設置
施工がはるかに容易であり、それだけ設備費が安
価になるという利点がある。 Furthermore, unlike the conventional case of installing an air storage tank on the seabed, there is no need to tow the air storage tank or sink it, so the installation is much easier than in the conventional case. This has the advantage that equipment costs are reduced accordingly.
特に、本発明では、空気充填袋を横坑内に配設
しているので、空気洩れを完全に防止でき、信頼
性の高い運転が可能になるという利点がある。 In particular, in the present invention, since the air-filled bag is disposed within the shaft, there is an advantage that air leakage can be completely prevented and highly reliable operation is possible.
