Title
(EN) SYSTEM AND METHOD FOR DENSE ENERGY STORAGE
(FR) SYSTÈME ET PROCÉDÉ POUR LE STOCKAGE D'ÉNERGIE DENSE
Abstract
(EN)
A system for storing energy for outputting on demand, is disclosed, comprising a flywheel, constituting a spinning mass upon rotation thereof, an energy exchanging arrangement configured to convert energy into angular momentum of the spinning mass, and to retrieve kinetic energy from the spinning mass, a rechargeable electrical storage device which its mass constitutes a portion of the mass of the flywheel, and a control system for administering energy flow into and out from the flywheel and from the electrical storage device, whereby when the flywheel spins and the electrical storage device is both spinning as part of the flywheel and electrically charged, the density of extractable energy, stored in the electrical storage device includes the amount of extractable kinetic energy stored in its mass due to spinning. Method for increasing energy storage density in combined flywheel and electrical storage devices is also disclosed.

L'invention concerne un système pour stocker de l'énergie à délivrer en sortie à la demande, comprenant un volant d'inertie, constituant une masse tournante lors de la rotation de celui-ci, un agencement d'échange d'énergie conçu pour convertir de l'énergie en un moment cinétique angulaire de la masse tournante et pour récupérer l'énergie cinétique à partir de la masse tournante, un dispositif de stockage d'énergie électrique rechargeable dont la masse constitue une partie de la masse du volant d'inertie, et un système de commande pour administrer un flux d'énergie dans le volant d'inertie et hors du volant d'inertie et à partir du dispositif de stockage d'énergie électrique, moyennant quoi, lorsque le volant d'inertie tourne et que le dispositif de stockage d'énergie électrique est à la fois en rotation en tant que partie du volant d'inertie et chargé électriquement, la densité d'énergie extractible, stockée dans le dispositif de stockage d'énergie électrique, comprend la quantité d'énergie cinétique extractible stockée dans sa masse due à la rotation. L'invention concerne également un procédé d'augmentation de la densité de stockage d'énergie dans des dispositifs de stockage d'énergie électrique et un volant d'inertie combinés.
