- the compressed air is then stored in a tank, the tanks of significant capacity being to date natural or artificial underground cavities.
- the compressed air is extracted from the tank, heated by extra external heat energy, for example by fuel, natural gas, electric power or any other source heat, and expanded through a turbine that drives an electric generator.

- This arrangement makes it possible in particular while producing and storing compressed air from a source of electrical power of poor quality or fluctuating, for example provided by a wind farm, to produce, in the installation 9 of relaxation, at the same time stabilized electrical energy by destocking and relaxing compressed air.
- the reservoir 1 for storing the fluids then plays a role in damping the fluctuations of the source of electrical energy.
- the ability to use the device with the motor assembly and the generator assembly 16 operating at the same time can also be used.
- the device operates in two stages, which can take place simultaneously:
- a step of storing the gas comprising the following operations:
- a step of restitution of the gas comprising the following operations:
- the regulation and control system of the motor assembly for injecting the liquid maintaining the constant pressure in the reservoir 1 for storing the fluids.
- This main regime is used when the desired variations of the electrical power at the input of the device, in the case of the step of storing the electrical energy, or at the device output, in the case of the recovery step of the device. electrical energy, are respectively compatible with the allowable speeds of power variation of the compression installation 8 and with the allowable speeds of variation of power of the installation 9 of relaxation.
- a transient regime can be implemented, which makes it possible to temporarily increase the possible power variations of the device before reaching the main operating mode, by adjusting the power of the motor assembly and the set 16 generator.
- a first case may be the start since the shutdown of the device with a high load taking speed following a request for a level of energy.
- control and control devices will first start the installation 9 of relaxation with a speed of variation of power compatible with this installation.
- this power take-off is not fast enough, for example when the energy level is requested in a time incompatible with the speed of variation of the installation 9 of expansion, the set 16 generator will be simultaneously turned on, to allow to generate additional electrical power and reach the energy level requested.
- the control and control system of the assembly 16 generator controls the pressure drop in the reservoir 1 of fluid storage due to the simultaneous evacuation of gas and liquid.
- the generator assembly 16 and the expansion device 9 are implemented simultaneously, temporarily. Indeed, particularly in the case where the gas used is air and the liquid is water, the response time of the generator set 16 is much lower than that of the installation 9 of relaxation, so that the whole 16 generator provides a faster response, but a temporary response, to an urgent need for energy.
- the pressure in the fluid storage tank 1 will then necessarily decrease.
- the generator set 16 will see its power progressively diminished until it stops as the ramp 9 is expanded.
- the engine assembly is started and will be subjected to a gradual increase in power to allow to find the pressure levels in the reservoir 1 of fluid storage corresponding to the main operating regime .
- the device is in a step of restitution of energy, but an increase in the energy level delivered by the installation 9 of relaxation is required.
- the power of the expansion system 9 must be increased gradually from the demand, at a speed compatible with the installation 9 of relaxation. This speed may not be sufficient to satisfy the call within a reasonable time. Then, advantageously, the power of the motor assembly, which injected water into the fluid storage tank 1 in the main mode, will be progressively reduced, so that the device consumes less energy, and therefore provides more.
- the power of the source 8 compression system energy can vary.
- the compression installation 8 is powered by solar energy, the power of which necessarily varies with the weather conditions.
- the generator assembly 16 which can produce energy by virtue of the turbine 17 through which the liquid 3 discharged from the tank 1 fluid storage, can be quickly ramped up power to stabilize the power of the installation 8 compression.
- the motor assembly which is stationary in the main operating regime during the storage operation, is then quickly started and ramped up to consume some of the energy produced surplus and not consumed by the compression installation 8.
- the powers of the motor assembly and the generator assembly 16 may be modified from the main operating speed so as to allow high power variation speeds, the device returning to the main operating mode gradually.
- the gas 2 in the fluid storage tank 1 is preferably separated from the liquid 3 by fluid-tight separation means, such as a rigid and movable diaphragm 23 separating the fluid storage tank 1 into a part containing the gas. 2 and a portion containing the liquid 3.
- the diaphragm 23 then defines a separation surface between the liquid and the gas, and is movable with changes in the volume of the gas and the liquid during storage and retrieval operations of the gas.
- the separation means must be able to move during storage and retrieval operations of the gas, so that the volume of the portion containing the gas decreases when the gas is removed from storage while the volume of the portion comprising the liquid increases and, conversely, so that the volume of the gas-containing portion increases as the gas is stored while the volume of the liquid-containing portion decreases.
- the diaphragm 23 is preferably equipped with one or more seals 24 at its periphery in order to maintain a separation between the pressurized gas and the liquid in the fluid storage tank 1 and to avoid the dissolution phenomena of the fluid. gas in the liquid or pollution of one of the two fluids by the other.
- the two fluids in the fluid storage tank 1 exert pressure on each other via the diaphragm 23.
- seals 24 in particular by their material, form and sealing principle, is suitable for fluids 2 and 3, and storage conditions such as pressure and temperature. It must also ensure a sufficient life of the joints, in particular with good wear resistance resulting from the friction on the internal surface of the reservoir resulting from the displacement of the diaphragm 23 during storage and removal of the gas.
- the seals 24 may be inflatable seals. To increase the seal between the gas and the liquid, at least two seals 24 can be used so as to constitute successive dams.
- the separation surface between the air 2 and the water 3 is in a horizontal plane.
- the air 2 then necessarily occupies the upper part of the fluid storage tank 1 and the water the lower part of the fluid storage tank 1.
- the diaphragm 23 can then simply float on the surface of the water, so as to move with the variations of the volume of water.
- the diaphragm 23 of rigid separation can be replaced by a membrane of flexible material separating air and water, so that the volume of the parts containing the water and the gas are of variable volume by deformation of the membrane .
- FIG. 3 thus represents a particularly advantageous variant of separation means between a gas and a liquid in a fluid storage tank 1, in which the separation surface between the gas and the liquid is not in a horizontal plane.
- the separation surface is in a vertical plane, or in a plane inclined by a few degrees, for example between 1 ° and 10 °, with respect to the vertical plane. This may be the case if it is more advantageous that the fluid storage tank 1 is in a horizontal position, placed on the ground, buried, or when its length dimensions do not allow a vertical position.
- the rigid diaphragm 23 is then provided on its periphery with bearing surfaces on the body of the fluid storage reservoir 1, these bearing surfaces having large dimensions, so as to be offset on either side of the plane of the diaphragm 23, and therefore of the separation surface between the gas and the liquid, in order to resume the moments of the forces applied.
- bearing surfaces are made of a material resistant to compression under the effect of the pressure in the reservoir 1 for storing fluids and facilitating sliding on the body of the reservoir 1 for storing fluids to move the diaphragm 23.
- the support surfaces may be continuous over the entire circumference of the reservoir, discontinuous by being equally distributed over the circumference of the reservoir, or discontinuous by being distributed unequally, for example with a greater total bearing surface on the lower and upper parts of the reservoir, where the pressure exerted by the fluids on the diaphragm 23 is the highest.
- the width of the support surfaces 30 may be constant or not on the circumference of the reservoir.
- the unit contact surface between the bearing surfaces and the reservoir may be the same for all the supports or be different depending on the supports.
- the supports may also include rolling mechanisms such as for example wheels to facilitate the movement of the diaphragm.
- the offset of the bearing surfaces 30 from the plane of the diaphragm 23, i.e., the greatest distance between a point of a bearing surface and the plane of the diaphragm 23, may not be the same for all bearing surfaces. Thus, it may be more important for the bearing surfaces placed on the lower part of the tank, in particular because of a stronger pressure exerted by the water on the lower part of the diaphragm 23.
- the diaphragm 23 is then perfectly centered in the reservoir 1 for storing the fluids, that is to say that it does not rock under the effect of the pressures exerted on its two faces, and the seal or seals 24 are correctly maintained, even when moving during storage and retrieval operations.
- the bearing surfaces can also contribute to the seal between the gas and the liquid.
- the diaphragm 23 thus provided with bearing surfaces 30 makes it possible, in any reservoir 1 for storing fluids, to seal between two fluids contained while allowing the volume of the portion containing a first fluid and the volume containing the second fluid. to vary by displacement of the diaphragm 23.
- the fluid storage tank 1 In the case where the separation surface between the gas and the liquid is inclined a few degrees with respect to the vertical plane, it is advantageous to arrange the fluid storage tank 1 so that the lowest part 33 is the part containing the gas and therefore the highest part 34 is the part containing the liquid. Therefore, in the event of failure of the diaphragm 23 and / or seals 24 between the gas and the liquid, any leakage of the liquid 3 to the gas 2 through the diaphragm 23 will necessarily flow to the part 33 the lowest fluid storage tank 1, this liquid can be recovered and returned to the other side of the diaphragm 23, in the portion containing the liquid, by a low power hydraulic pump 31.
- any leakage of the gas to the liquid through the diaphragm 23 will necessarily flow to the highest part 34 of the fluid storage tank 1, in the part containing the liquid.
- This gas can be brought on the other side of the diaphragm 23, in the part containing the gas, by a low-power air compressor 32.
- the lowest part 33 and the highest part 34 of the fluid storage tank 1 are placed at opposite ends of the tank 1 so as not to hinder the complete movement of the diaphragm 23.
- FIGS. 11 and 12 there is shown a further provision of the present invention for storing gas and returning it according to an adiabatic cycle, particularly in the case where the gas is expanded to produce electrical energy. by the installation 9 of relaxation.

- the expansion device 9 comprises at least one stage, for example three stages 88a to 88c, of expansion of the gas, each stage 88a to 88c of relaxation being associated with at least one exchanger 87a at 87c of heat, for example placed at the entrance of each stage 88a to 88c relaxation, recovering the heat of the heat transfer fluid 86 and transfer it to the gas before or during relaxation in each stage 88a to 88c relaxation.
- the expansion stages 88a to 88c each associated with a heat exchanger 87a to 87c can be arranged in series or in parallel.
- the heat exchange system then comprises at least one heat reservoir 84, 91 for storing the heat transfer fluid heated by the compression of the gas in the compression installation 8.
- the heat reservoir 84, 91 is thermally insulated and includes means for placing a heat transfer fluid 86 under pressure.
- the heat-exchange fluid 86 coming from the exchangers 80a to 80c of the compression installation 8, passes through a pipe 83 thermally insulated and fills the heat reservoir 84, preferably also thermally insulated, placed in the portion containing the gas 2 in the reservoir 1 for storing fluids, so as not to hinder the complete movement of the diaphragm 23
- the means for putting the heat transfer fluid under pressure comprises, as in FIG. 1 1, a piston 85, thermally insulated, at the interface between the gas in the fluid storage tank 1 and the heat transfer fluid 86 in the reservoir 84, 91 heat.
- the coolant 86 is therefore maintained at the pressure of the compressed gas 2 in the fluid storage tank 1.
- heat transfer fluid 86 is water.
- the volume of the water storage, as heat transfer fluid 86, in the fluid storage tank 1 will not exceed a few% of the volume of the air storage. Heat losses will therefore remain very limited.
- Each exchanger 87a to 87c of the expansion device 9 is supplied with heat transfer fluid 86 from the heat reservoir 84 inside the fluid storage tank 1 and is connected to the fluid storage tank 1 via an isolated pipe 89. thermally.
- a pump 90 allows the pressurization of the coolant 86 at the inlet of the exchangers 80a to 80c of the stages 81a to 81c of compression.
- An expander 97 allows the expansion of the coolant 86 at the outlet of the exchangers 87a to 87c of heat.
- the storage of the coolant 86 in the heat reservoir 84 located in the fluid storage tank 1 is at the same time as the storage of the gas 2 in the fluid storage tank 1.
- the generator assembly 16 comprising the turbine 19 controlled by a control system makes it possible to maintain the pressure inside the reservoir 1 for storing the fluids constant during this operation.
- the removal of the heat transfer fluid 86 from the heat reservoir 84 located in the fluid storage tank 1 is at the same time as the removal of the gas 2.
- the motor assembly comprising the pump 17 controlled by a control system makes it possible to maintain the constant pressure inside the fluid storage tank 1 during this operation.
- the heat reservoir 91 for storing the coolant 86 is not positioned in the fluid storage tank 1, but externally thereto.
- the heat reservoir 91 comprises a portion supplied with heat transfer fluid 86 and a portion supplied with compressed gas, that of the fluid storage reservoir 1, the two parts being situated respectively on either side of a diaphragm 95 placed in the chamber. heat reservoir 91 ensuring the seal between the two parts.

- the gas coming from the fluid storage tank 1 is, before entering the heat reservoir 91, expanded to a pressure substantially greater than the vaporization pressure of the coolant 86 at its storage temperature. This prior expansion is particularly advantageous in the case where the coolant is water, to maintain the water in the liquid state and facilitate storage in the tank 91 of heat.
- the inlet and outlet port of the heat transfer fluid 86 is connected by one or more pressure-resistant pipes 93 to a pipe 83 coming from heat exchangers 80a to 80c of the compression installation 8, as described previously, and to a pipe 89 from heat exchangers 87a to 87c of the installation 9 of expansion, as described above.

- the expanded gas is not then released into the atmosphere but is advantageously used by the industrial plant.
- the gas has not been warmed beforehand or during its expansion by a heat source. Its temperature at its outlet from the expansion device 101 is therefore lower than its storage temperature in the storage tank 1, which makes it possible to use the expanded gas as a cooler either directly in the industrial process in the industrial installation 102 or in any other process.
- the industrial installation 102 is directly connected to the orifice 36 of the gas outlet of the fluid storage tank 1, so as to directly use the compressed gas.
