Title
(EN) ENERGY STORAGE AND DELIVERY SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE STOCKAGE ET DE DISTRIBUTION D'ÉNERGIE
Abstract
(EN) An energy storage and delivery system (100) includes a crane (120) or elevator cage (1200), where the crane or elevator cage is operable to move one or more blocks (1300) from a lower elevation to a higher elevation to store energy (e.g., via the potential energy of the block in the higher elevation) and operable to move one or more blocks from the higher elevation to the lower elevation (e.g., by gravity) to generate electricity (e.g., via the kinetic energy of the block when moved to the lower elevation). The blocks are moved between the lower elevation and the higher elevation by an equal vertical distance.
(FR) L'invention concerne un système de stockage et de distribution d'énergie (100) comprenant une grue (120) ou cage d'élévateur (1200), la grue ou cage d'ascenseur pouvant servir à déplacer un ou plusieurs blocs (1300) depuis un niveau inférieur vers un niveau supérieur afin de stocker de l'énergie (par exemple, par le biais de l'énergie potentielle du bloc situé au niveau supérieur) et pouvant servir à déplacer un ou plusieurs blocs depuis le niveau supérieur vers le niveau inférieur (par exemple, par gravité) afin de générer de l'électricité (par exemple, par le biais de l'énergie cinétique du bloc lorsqu'il est déplacé vers le niveau inférieur). Les blocs sont déplacés entre le niveau inférieur et le niveau supérieur sur une distance verticale égale.
