Definitions
- Underground storage system for storing fluids
- the invention relates to the field of underground storage, in particular for the storage of fluids. More particularly, the invention relates to the field of underground storage systems for gas storage, for example for hydrogen storage or for oxygen storage. Even more particularly, the invention relates to the field of storage of high pressure fluids.
- high pressures is meant pressures which may be between 100 bar to 1200 bar, more particularly between 200 bar and 500 bar.
- the invention also relates to an underground storage method for the storage of fluids.
- [5]Certain gases such as hydrogen
- their low density requires storage at high pressure, and their small molecules and low viscosity make them prone to leaks. Consequently, they must be stored in a perfectly sealed device, capable of storing large quantities of gas, while meeting strict safety standards, in particular to minimize the risk of leaks.
- Underground storage is also interesting for consumers and manufacturers because it makes it possible to very effectively reduce the space used above ground for these storage facilities.
- a device comprising a unit fixed in a single underground borehole, the unit comprising a plurality of containers separated and fixed via at least one retaining device, each container of the plurality of separate containers having at least one cap including an inlet hole, an outlet hole and a central hole, the central hole being positioned eccentrically relative to a radial center of a upper surface of the plug, the unit being secured in the single underground borehole by cement extending continuously between the plurality of containers to surround the unit and contact a side wall of the underground borehole. Additionally, the unit is attached to an anchor element near the bottom of the underground borehole.
- a first aim of the invention is to facilitate maintenance operations on an underground storage system for fluids, such as gases. Furthermore, a second aim of the invention is to make it possible to store large quantities of fluids at high pressures while respecting strict safety standards. Finally, a third aim of the invention is to allow the underground storage of several different fluids, at different pressures, in a single device, within a single storage system.
- the invention provides an underground storage system for the storage of fluids, said storage system comprising:
- a support element comprising at least one opening capable of receiving an assembly element
- At least one tank said tank having a longitudinal axis (1), a lower end and an upper end,
- first closing means capable of closing the tank at its lower end

- G is the length of the axial clearance expressed in meters
- L represents the length of a tank (10) expressed in meters
- P represents the geothermal gradient expressed in degrees Celsius per meter
- a represents the thermal expansion coefficient of the metal expressed in Celsius' 1 .
- the geothermal gradient P varies depending on the geological formation in which the storage system is placed.
- P is such that 0.02°/m ⁇ p ⁇ 2°/m.

- the coefficient of thermal expansion varies depending on the type of metal that makes up the tubes used to form a tank.
- a is such that 8*10' 6 °C' 1 ⁇ a ⁇ 18*10' 6 °C' 1 .
- the reservoir is composed of a single tube.
- the tubes used to make a tank are metal tubes, preferably threaded metal tubes.
- these may be metal tubes made of titanium, or steel tubes of the type used in the gas and oil industry, in particular tubes used to create gas and/or oil production wells. oil.
- the first closing means and/or the second closing means is capable of closing the tank by screwing.
- the thread of said closing means can be a male or female thread.
- the first closing means and/or the second closing means may also comprise a metal surface. The presence of a metal bearing helps to improve the tightness of the closure, which is particularly advantageous for gas storage, particularly for the storage of hydrogen which is a gas particularly prone to leaks.
- the first closing means and/or the second closing means is a weld.
- Closing means capable of closing the tank by screwing are preferred to welds, because the screwed closing means do not significantly modify the thickness of the tank wall at the level of the closure. Thus, with screw closure means the mechanical properties of the tank at the closure level are unchanged. In addition, in the case of hydrogen storage, they make it possible to avoid potential problems of corrosion by dihydrogen, which can occur on a weld.
- the support element comprises an upper surface 54 and a lower surface 56.

- the collar 52 has a second thickness e which can be between 5 mm and 200 mm.
- the support element 4 is a metal plate in which the first thickness E is equal to 250 mm, and the second thickness e is equal to 100 mm.
- the support element 4 further comprises an upper surface 54, said upper surface 54 being opposite the lower surface 56 of the flange 52 and, said upper surface 54 having an area equal to 8.6 m 2
- the support element 4 also comprises six openings 7.
- the openings 7 are through holes, arranged in the first thickness E of the body 50 of the support element 4.
- each tank 10 is suspended from the support element 4 via an assembly element 18.
- an axial play G remains between on the one hand , the first way to closure 16 which closes the tank 10 at its lower end 14, and on the other hand, the bottom 3 of the recess 2.
- This axial clearance G has the function of absorbing axial thermal expansion of the tank 10, which occurs in particular during filling and emptying operations.
- the dimensioning of the axial clearance G depends directly on the surrounding conditions of the storage system 1, in particular on the conditions of temperature, pressure, and the capacity of the tank 10 to elongate. when subjected to variations in temperature and pressure, particularly during filling and emptying operations.
- the axial clearance G of any tank 10 of the storage system 1 responds to the following inequality:
- G is the length of the axial clearance expressed in meters.
- L represents the length of a tank 10 expressed in meters.
- P represents the geothermal gradient expressed in degrees Celsius per meter.
- the geothermal gradient P varies depending on the geological formation in which the storage system 1 is placed. Thus P is such that 0.02°/m ⁇ p ⁇ 2°/m.
- a represents the coefficient of thermal expansion of the metal expressed in degrees Celsius' 1 .
- the thermal expansion coefficient a varies depending on the type of metal that makes up the tubes used to form a tank 10.
- a is such that 8*10' 6 °C' 1 ⁇ a ⁇ 18*10' 6 °C' 1 .
- the tanks 10 are tubular, of circular section, and each have a longitudinal axis (1), a lower end 14 and an upper end 12.
- each reservoir is closed at its lower end 14 by a first closing means 16, and each tank 10 is closed at its upper end 12 by a second closing means 17.
- the lower end 14 and the upper end 12 of each reservoir 10 are threaded ends, and the first closing means 16 and the second closing means 17 also have a thread, said thread being complementary to the thread of the lower ends 14 and upper end 12.
- the second closing means 17 is equipped with sensors 19 which are pressure gauges, thermometers and leak detectors.
- the first closing means 16 can also contain pressure gauges, thermometers and leak detectors. Other types of sensors can be used depending on the objective that has been set.
- each tank 10 can be composed of a plurality of tubes A.
- the tanks 10 are composed of several threaded tubes A.
- the tubes A are assembled by screwing so as to form a column C of tubes A.
- a reservoir 10 can also be composed of a single tube A, closed at its ends 12 and 14 by closing means 16 and 17.
- each reservoir 10 is assembled to an assembly element 18.
- Each assembly element 18 is inserted into an opening 7 and is retained by a flange 62 which abuts against the upper surface 54 of the support element 4.
- Each assembly element 18 is therefore suspended from the support element 4. In this way, each tank 10 is suspended from the support element 4 via the assembly element 18 to which it is assembled.
- an assembly element 18 is a tubular metal part, of circular section, which comprises a tubular body 60 and a flange 62.
- the body 60 of the assembly element 18 is fixed to the upper end 12 of a tank 10, preferably by screwing. It is possible to use welding in an alternative embodiment.
- the body 60 of the assembly element 18 has a male or female thread (not shown) complementary to the thread of the upper end 12 of the tank 10 to which said assembly element 18 is assembled.
- the flange 62 comprises an upper surface 64 and a lower surface 66.
- each assembly element 18 is inserted into an opening 7 of the support element 4.
- Each assembly element 18 rests on the element support element 4 via its lower surface 66 which abuts against the upper surface 54 of the support element 4.
- each assembly element 18 is assembled to a tank 10 by screwing to the upper end 12 of said tank 10.
- the flange 62 of the assembly element 18 therefore allows the latter to rest on the upper surface 54 of the support element 4.
- the assembly element 18 does not need to be fixed to the support element 4, for example by welding or by screwing, which simplifies the assembly of the storage system 1, in particular for suspending the tanks 10.
