Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is useful for correcting inconsistencies between energy production and consumption, such as excess or deficiency in the amount of power generation and consumption, and for effectively utilizing insufficiently developed or undeveloped energy, such as the clean and inexhaustible sun. It is related to.

0002

BACKGROUND OF THE INVENTION As energy storage methods, storage batteries, pumped storage power generation, heat storage, etc. are cited as major methods. Storage batteries have been widely used since ancient times and are a well-developed storage method for storing electrical energy by converting it into chemical energy, but the biggest unsolved problem is the loss during storage due to spontaneous discharge.

[0003] Pumped storage power generation has been known for a long time, and uses surplus electricity to pump up water in dams or water tanks, storing it as potential energy, and generating hydroelectric power when electricity consumption is high, making up for power shortages. There are many problems, such as the space required for storage, safety, and losses during storage due to water leakage and natural evaporation.

[0004] Thermal storage method is the storage of thermal energy itself, which has already been conveniently applied to household goods on a small scale. In large-scale cases, there are problems with heat storage materials and their installation space, but no matter what kind of insulation material is used, 100%
There is no such thing as insulation. That is, heat loss becomes a serious problem.

[0005] As seen in the above examples, energy storage methods such as electricity, position, and heat that are currently in practical use have overcome various problems, but they also suffer from natural discharge, water leakage, and heat dissipation. It is still difficult to prevent such storage losses. In addition, light energy, sound energy, etc. are not suitable for storage, chemical energy generally requires complicated operating equipment, and nuclear energy is very promising, but it will take a considerable amount of time to put it into practical use. .

[0006]

[Problem to be Solved by the Invention] The problem to be solved is to bring the natural loss in energy storage as close to zero as possible using the simplest possible method.

[0007]

[Means for Solving the Problems] The present invention operates a compressor using energy to be stored, changes gas into high-pressure gas or liquefied gas, and uses the kinetic energy of the gas to convert into a cylinder or a pressure-resistant container/equipment/device in place of a cylinder. It is characterized by being stored in a facility. The stored energy is released when needed, and the energy contained in the compressed gas is used directly or indirectly (converted into other forms of energy, such as rotational force using a turbine, electricity using a generator, etc.). This method uses a simple method of operating electric motors, compressors, turbines, generators, etc., and since losses during storage can only be considered by opening or destroying the storage cylinders, there is no natural loss of stored energy. Realize the purpose of

[0008]

[Example] A cylinder is filled with compressed air using a compressor linked to an electric motor driven by electricity generated by solar cells during the day on a clear day.The compressed air released from the cylinder drives a turbine at night or as needed. Then, a generator connected to this generates electricity. In addition, an integrated gas compression energy storage facility is assembled by combining an electric motor and a generator, and a compressor and a turbine.

[0009] If surplus electricity is used at night at an LPG filling station, the LPG filling fee can be saved and the price reduced. On the other hand,
Daytime electricity generated from thermal power generation will be saved, and this will become part of air pollution control.

0010

[Effects of the Invention] As explained above, the gas compression energy storage method of the present invention equalizes the excess and deficiency of energy demand regardless of whether it is for civilian use or industry, such as day and night, four seasons, or irregular electricity demand, and also uses solar heat and sunlight. - It will help promote the development of unused and undeveloped energy, such as wind power, which is clean but tends to generate irregularly, and will play a role in preventing air pollution and preserving a clean earth.
