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.

The underground storage method for compressed air of the present invention to achieve the above object is carried out at a predetermined depth underground, for example, 200 m
An air storage chamber capable of storing air is formed by partitioning a horizontal shaft connected to the bottom of a vertical shaft excavated to a depth of about 300 m with a partition wall, and water is poured into the horizontal shaft and vertical shaft. When the air is full, compressed air is filled into the air storage chamber using nighttime electricity using a compressor installed on the ground, etc.
The compressed air in the air storage chamber is discharged through a pipe during peak power consumption, such as during the day, to rotate a power generation turbine and supply power.

According to the underground storage method and device for compressed air of the present invention described above, the air storage chamber is set in a horizontal shaft excavated underground, so that floating due to buoyancy as in conventional cases installed on the seabed is not possible. There is no need for protection, and since the air storage chamber is constructed directly underground, there is the advantage that underground space can be used effectively.
また、空気貯蔵室には、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 storage chamber, there is an 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
る場合のように、空気貯蔵槽の曳航や、沈設等の
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、仕切壁を用いて横坑自体を
そのまま空気貯蔵室に使用しているので、それだ
け設備費が安価になるという利点がある。 In particular, in the present invention, since the horizontal shaft itself is used as an air storage chamber by using a partition wall, there is an advantage that the equipment cost is reduced accordingly.
