Title
(EN) SUBMERGED ENERGY STORAGE AND EXTRACTION SYSTEM
(FR) SYSTÈME DE STOCKAGE ET D'EXTRACTION D'ÉNERGIE IMMERGÉ
Abstract
(EN)
Energy storage and extraction systems for storing and extracting electric energy through use of hydrostatic potential are disclosed. The systems can comprise either or both of a buoyant member and a non-buoyant member. The buoyant member and the non-buoyant member can be coupled to a link member, in some cases via tethers, and the link member can be coupled to an anchor. The link member can also be coupled to an energy conversion device that is capable of converting electric energy to mechanical energy, or mechanical energy to electric energy, or both. In some embodiments, at least one wave harvester is used to extract energy. In other embodiments, a buoyant member can be confined within a chamber having an inlet and an outlet. In yet other embodiments, a buoyant member is used to extract energy from a body of water having a varying surface level.

L'invention concerne des systèmes de stockage et d'extraction d'énergie pour stocker et extraire de l'énergie électrique par l'utilisation d'un potentiel hydrostatique. Les systèmes peuvent comprendre l'un ou l'autre, ou les deux, d'un élément non flottant et d'un élément non flottant. L'élément flottant et l'élément non-flottant peuvent être couplés à un élément de liaison, dans certains cas des attaches, et l'élément de liaison peut être couplé à une ancre. L'élément de liaison peut également être couplé à un dispositif de conversion d'énergie qui est capable de convertir de l'énergie électrique en énergie mécanique, ou de l'énergie mécanique en énergie électrique, ou les deux. Dans certains modes de réalisation, au moins un dispositif d'exploitation des vagues est utilisé pour extraire l'énergie. Dans d'autres modes de réalisation, un élément flottant peut être confiné à l'intérieur d'une chambre ayant une entrée et une sortie. Dans encore d'autres modes de réalisation, un élément flottant est utilisé pour extraire de l'énergie à partir d'une masse d'eau ayant un niveau de surface variable.
