System and method for storing and recovering energy using compressed-gas with recovery liquid

A heat storage and recovery system and process includes at least one cylindrical external wall, at least one first volume, at least one second volume and at least two fluid injection/withdrawal devices. The first and second volumes are separated by at least one heat storage system comprising at least one bed of heat storage particles. Furthermore, the storage system and the first and second volumes extend substantially over the entire axial length of the cylindrical external wall. The longitudinal axis of the said cylindrical external wall is horizontal. A system and a process for the storage and recovery of energy by compressed gas include such a heat storage means.

The invention relates to a system and to a method for compressed-gas energy storage and recovery comprising at least a first and at least a second heat exchanger, a cold liquid storage means and a hot liquid storage means, as well as a separation means. The separation means is positioned after at least a first heat exchanger. The system comprises at least one means for feeding the liquid leaving the separation means to the cold liquid storage means.

Method for storing and producing energy with optimized water management

The present invention concerns a device and a process for the storage and restitution of heat which comprises at least two concentric heat storage volumes (TES, TES, TES). The walls () delimiting these storage volumes are configured in a manner such that the thickness of the wall delimiting the central storage volume is greater than the thickness of the wall delimiting the peripheral storage volume.

The invention is a compressed gas energy storage and recovery system and method, of AACAES type. The system and the method according to the invention heats at constant volume stored compressed gas to increase the pressure of the stored compressed gas.

Compressed air energy storage and recovery system and method with constant volume heating

The invention relates to a container () for a heat storage and restitution system, comprising a vessel in which a gas is circulating in order to be cooled or heated. The vessel is limited by a first jacket formed from concrete () surrounded by a thermally insulating layer (), which is itself surrounded by a steel shell (). The vessel comprises at least two modules (), each comprising a double wall formed from concrete and a perforated base () limiting at least two volumes (and) which are each capable of containing a fixed bed of particles of a material for storage and restitution of heat (). The modules are disposed one above the other in a centered manner such that the double wall formed from concrete forms the first jacket formed from concrete () and a second jacket formed from concrete ().

Container for a system for storing and restoring heat, comprising a double wall formed from concrete

The invention is an ocean thermal energy conversion method and a system in which a motive fluid having predetermined characteristics is circulated in a closed loop between a cold source in cold deep ocean water and heat sources in warm surface water. The motive fluid is compressed between the cold source and a first primary warm water heat source resulting in the motive fluid being substantially totally vaporized at an outlet of the warm water heat source. The motive fluid is heated downstream from the primary heat source by a secondary heat source. The thermal energy of the heated motive fluid is recovered from a turbine and the motive fluid is condensed in the cold source.
