摘要： A carbon dioxide tank (3) is connected to a pump device (5). The pump device (5) is joined and connected with an infusion well (9), which is a tubular body. The infusion well (9) extends downward beneath the ground (7) and is provided so as to reach a saltwater aquifer (11). Part of the infusion well (9) forms a horizontal well (10) in a substantially horizontal direction. In other words, the horizontal well (10) is a location in which part of the infusion well (9) is formed in a substantially horizontal direction within a saltwater aquifer (11). The horizontal well (10) is provided with filters (13), which are porous members. For the filters (13), for example, a fired member in which ceramic particles are mixed with a binder that binds those particles can be used. Moreover, if the hole diameter for the filters (13) is small, microbubbles with a smaller diameter can be generated.

摘要： A method for providing the recharge of water into underground aquifers while preventing the mobilization of trace metals. The recharge water may be used for storage and subsequent withdrawal, or to regain or increase the long term beneficial use of an aquifer. The recharge water may be also be used to influence the groundwater flow in the aquifer. Water is treated and recharged by the addition of a small amount of a sulfide compound to remove dissolved oxygen and prevent dissolution of negative valence sulfur bearing minerals, such as pyrite, in the subsurface. The recharged water may increase the pressure head in the aquifer, alter the groundwater flow pattern to prevent the encroachment of objectionable quality water, or to segregate water of different quality. The recharge water may be fresh or brackish depending on the specific objectives of the application.

摘要： A method and system for storing and supplying hydrogen to a hydrogen pipeline in which a compressed hydrogen feed stream is introduced into a salt cavern for storage and a stored hydrogen stream is retrieved from the salt cavern and reintroduced into the hydrogen pipeline. A minimum quantity of stored hydrogen is maintained in the salt cavern to produce a stagnant layer having a carbon dioxide content along the cavern wall and the top of a residual brine layer located within the salt cavern. The compressed hydrogen feed stream is introduced into the salt cavern and the stored hydrogen stream is withdrawn without disturbing the stagnant layer to prevent carbon dioxide contamination from being drawn into the stored hydrogen stream being reintroduced into the hydrogen pipeline.

摘要： An installation for storing of natural gas or some other fluid comprises a lined underground storage space (10). Inside the rock wall (11) of the storage space there is a concrete layer (27) for supporting an inner impermeable lining layer (14). According to the invention, the concrete layer has a crack distribution control reinforcement layer (28) closer to the impermeable lining layer (14) than to the rock wall (11) in order to divide large cracks into smaller cracks and distribute the cracks over a larger area of the impermeable lining layer. Further, also according to the invention, there is between the impermeable lining layer (14) and the concrete layer (27) a non-binding sliding layer (29) to facilitate relative movements between the impermeable lining layer and the concrete layer.

摘要： A compressed gas storage tank 10 utilizes a rock-bed cavity 11 in which a bentonite slurry is fed into an underground cavity 11 formed in a rock-bed, a forcibly fed compressed gas is stored in said rock-bed cavity in a state in which the compressed gas is loaded with a pressure load of the bentonite slurry from the underside of the compressed gas, the bentonite slurry in the rock-bed cavity 11 is of a dual layer structure consisting of an upper layer composed of a light bentonite slurry 30 mixed with a filling-up material invading into and filling up a void and a crack formed in an inner wall surface and a lower layer composed of a heavy bentonite slurry 13 mixed with a high specific gravity fine powder as a load condition material. The filling-up effect of the bentonite slurry secures sufficient liquid-tightness and air-tightness in the ceiling part of the rock-bed cavity, making it possible to efficiently and economically store compressed gasses such as compressed air or natural gas without allowing them to escape.

摘要： The invention provides caverns and methods for producing caverns in bedded salt deposits. In a preferred method, a first bore hole (19) is drilled into the salt formation (10) and a cavity (13) for receiving insolubles is leached from the salt formation (10). Thereafter, at a predetermined distance away from the first bore hole (19), a second hole (17) is drilled towards the salt formation. The drill drills through the salt formation in a horizontal direction until it instersects the cavity (13) for receiving insolubles. This produces a substantially horizontal conduit (20) from which solvent is controlledly supplied to the surrounding salt formation, leaching the salt and producing a concentrated brine which is removed through the first bore hole (19). Insoluble are collected in the cavity (13) for receiving insolubles. By controlledly supplying solvent, a horizontal cavern is produced with two bore holes (17 and 19) extending therefrom.

摘要： Procédé de réduction de l'humidité dans une caverne souterraine naturelle ou artificielle. On a prévu (i) un dispositif d'injection dans la caverne d'un gaz relativement sec, et (ii) un dispositif d'extraction de gaz de la caverne. Chacun de ces dispositifs comporte un tube de transfert de gaz présentant une extrémité ouverte débouchant dans ladite caverne, l'extrémité ouverte de l'un des tubes de transfert étant placée plus bas que celle de l'autre. Ledit procédé consiste à injecter dans la caverne un gaz relativement sec par l'intermédiaire de l'un des tubes de transfert de gaz, puis à extraire par l'intermédiaire de l'autre tube un gaz présentant une teneur en vapeur d'eau plus élevée que celle du gaz relativement sec préalablement injecté. Ce procédé est bien adapté à la réduction de l'humidité dans une caverne destinée au stockage d'un fluide tel que le "gaz naturel".
