ADIABATIC COMPRESSED AIR ENERGY STORAGE SYSTEM AND METHOD

Номер: US20130061591A1

Принадлежит: ALSTOM TECHNOLOGY LTD.

During an adiabatic compressed air energy storage (ACAES) system's operation, energy imbalances may arise between thermal energy storage (TES) in the system and the thermal energy required to raise the temperature of a given volume of compressed air to a desired turbine entry temperature after the air is discharged from compressed air storage of the ACAES system. To redress this energy imbalance it is proposed to selectively supply additional thermal energy to the given volume of compressed air after it received thermal energy from the TES and before it expands through the turbine. The additional thermal energy is supplied from an external source, i.e. fuel burnt in a combustor. The amount of thermal energy added to the given volume of compressed air after it received thermal energy from the TES is much smaller than the amount of useful work obtained from the given volume of compressed air by the turbine. 1. An adiabatic compressed air energy storage (ACAES) system comprising:a compressed air storage;an air compressor that charges the compressed air storage with compressed air;a thermal energy storage (TES);a turbine that extracts useful work from the compressed air during discharge of the compressed air from the compressed air storage; andan energy balancer that redresses an energy imbalance between the TES and a required amount of thermal energy to raise the temperature of a given volume of compressed air to a desired temperature upon discharge of the given volume of compressed air from the compressed air storage;the energy balancer comprising a thermal energy input device selectively operable to supply additional thermal energy to the given volume of compressed air after it has received thermal energy from the TES and before it expands through the turbine, said additional thermal energy being supplied from a source external to the ACAES system, the amount of thermal energy added to the given volume of compressed air after it has received thermal energy from the ...

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. This allows the stored hydrogen stream to be reintroduced into the hydrogen pipeline without carbon dioxide removal. 1.

WATER STORAGE TANK WITH PASSIVE ENHANCED THERMAL ENERGY MANAGEMENT AND RESISTANCE

Номер: US20190145631A1

Принадлежит: FLEXCON INDUSTRIES, INC.

A water storage tank with passive enhanced thermal energy management is provided. The tank is formed of substantially cylindrical central section comprising a majority of the length along its axis and a dome-shaped section at each end, A first system of managing energy management includes providing insulation covering all or most of the tank in order to prevent heat flow energy leaving the tank. The strength of the insulation, is varied such that one end of the tank has less insulativity than the other end of the tank. Preferably change occurs gradually along the axial length of the tank. The second system for providing passive energy management is using insulation formed of a material that has a glass phase change temperature at or near the temperature of the water when it enters the tank. In order for the temperature of the water in the tank to change from the initial temperature it must first cause the insulation to make that glass phase change in order to either heat up or cool down from its initial temperature point. By varying the mass or thickness of the glass phase insulation along the axial length of the tank the amount of passive energy resistance to change varies thereby causing desired convection currents that serve to maintain a constant temperature within the tank thereby slowing any change of temperature at minimum cost. 11222. A double diaphragm tank with passive thermal management for the storage of water at temperatures up to 150° C. , while avoiding the use of active heating or cooling means , the tank comprising a central , substantially cylindrical housing section , joined at two circumferential locations and to an upper and a lower dome-shaped housing sections , and within the tank housing sections , and secured to the inner circumferential surface of the cylindrical housing section is a rigid diaphragm , and a flexible diaphragm , the upper circumferential rim of the rigid diaphragm being secured to the inner surface of the central housing ...

Thermochemical energy storage (TCES) for concentrating solar power (CSP) systems provides higher energy density than sensible energy storage systems. An ammonia-based TCES system dissociates endothermically into hydrogen and nitrogen. The stored energy is released when supercritical hydrogen and nitrogen react exothermically to synthesize ammonia. Prior ammonia synthesis systems are unable to produce temperatures consistent with modern power blocks requiring a working fluid, for example steam or carbon dioxide, to be heated to greater than 600° C., for example about 650° C. An ammonia synthesis system heats steam from, for example 350° C. to 650° C. under pressure of about 26 MPa. The hydrogen and nitrogen are preheated with a flow of supercritical fluid prior to the synthesis step to provide reaction rates sufficient to heat power block working fluid to the desired temperature. 1. A method for heating a working fluid for a power block to a temperature greater than 600° C. , the method comprising:providing a reservoir containing a thermochemical energy storage (TCES) fluid wherein the TCES fluid can transition between a higher-energy dissociated state and a lower-energy undissociated state;storing solar energy in the TCES fluid by flowing the TCES fluid from the reservoir through a dissociation reactor that is configured to endothermically transition at least a portion of the TCES fluid flowing through the dissociation reactor from the undissociated state to the dissociated state when the dissociation reactor is irradiated with concentrated solar energy, and returning the TCES fluid to the reservoir;transferring at least a portion of the stored solar energy from the TCES fluid into a power block working fluid by flowing the TCES fluid in the dissociated state from the reservoir to a synthesis reactor that is configured to exothermically transition at least a portion of the received TCES fluid from the dissociated state to the undissociated state, wherein the power ...
