採算がとれず実用化が阻まれている状態である。(Prior art and its problems) Attempts have been proposed to extract so-called rare resources from the sea, such as uranium and lithium, which have limited reserves underground.
For example, there is a method in which a multi-layer floating body in the shape of a ship equipped with an adsorption device for the target rare resource is placed in the sea, and seawater is passed through the floating body to collect the rare resource, or a method using a pump column is available. However, since the dissolved resources of seawater are minute, in principle a large amount of seawater must be distributed, which requires a large amount of electricity. Therefore, at the current stage, it is not economically viable and practical application is being prevented.

) The air compressor (1a) is driven by nighttime electricity using, for example, a generator (1b) as an electric motor, and the compressed air produced thereby is temporarily stored in a storage tank (2) installed underground or under the sea. Then, during the daytime peak of power demand, this stored compressed air A is supplied together with fuel to the combustor (1d) to drive the gas turbine (1c) to generate electricity. Note that (1e) is a cooler.

縮空気圧を一定にする方法である。By the way, in this case, the compressed air supplied to the combustor (1d) needs to be at a constant pressure. Therefore, a method that takes advantage of the fact that gas turbine power generation plants for peak power generation are generally located near urban areas and is located on the coast of a bay to secure fuel transportation facilities, is to use seawater (4) to stabilize the stored compressed air pressure. It is being This method uses, for example, a first step underground at a depth where water pressure that can counteract the compressed air pressure created is obtained.
As shown in the figure, a storage tank (2) is provided to temporarily store the compressed air produced by the air supply pipe (5), and an inflow and outflow pipe (6) for seawater is provided to control the valve (7). This is a method of keeping the compressed air pressure constant by naturally flowing in and out of the storage tank (2) an amount of seawater that compensates for the increase and decrease in the amount of compressed air due to storage of compressed air and power generation due to switching.
