Abstract
L'invention concerne un dispositif de stockage d'énergie à air comprimé basé sur un réservoir de liquide isolé contenant un compresseur d'air, un réservoir d'air comprimé et un moteur ou une turbine pneumatique. L'appareil utilise l'énergie mécanique d'entrée pour comprimer l'air et la chaleur générée est stockée dans le réservoir de liquide. L'air comprimé alimente un moteur pneumatique qui peut être couplé à un générateur électrique externe. L'énergie thermique stockée pourrait également être utilisée. Il pourrait être utilisé comme stockage d'énergie sur réseau ou hors réseau, ou comme mécanisme de stockage d'énergie à long terme. En outre, une version simplifiée du dispositif pourrait être utilisée comme source de stockage d'énergie de secours. Le dispositif pourrait également accepter et stocker l'énergie thermique fournie par l'utilisation de sources d'énergie renouvelables. A compressed air energy storage device based on an insulated liquid tank containing an air compressor, a compressed air tank and a pneumatic motor or turbine. The device uses input mechanical energy to compress the air and the generated heat is stored in the liquid reservoir. The compressed air powers a pneumatic motor which can be coupled to an external electrical generator. Stored thermal energy could also be used. It could be used as on-grid or off-grid energy storage, or as a long-term energy storage mechanism. Additionally, a simplified version of the device could be used as a backup energy storage source. The device could also accept and store thermal energy provided by the use of renewable energy sources.
Description
L'énergie produite par les sources renouvelables primaires est de nature très fluctuante. L'énergie solaire dépend des heures de la journée et du ciel clair, tandis que l'énergie éolienne est par nature intermittente et moins prévisible. Cela a de graves répercussions sur la fiabilité et le coût de l'énergie produite.
Le stockage d'énergie par air comprimé (CAES) est déjà testé à grande échelle depuis des décennies, mais son utilisation est restée limitée en raison de la complexité du système ainsi que de la nécessité d'utiliser des cavernes souterraines naturelles appropriées comme réservoirs.Energy produced by primary renewable sources is highly fluctuating in nature. Solar energy depends on the hours of the day and clear skies, while wind energy is inherently intermittent and less predictable. This has serious implications for the reliability and cost of the energy produced.
Compressed air energy storage (CAES) has been tested on a large scale for decades, but its use has remained limited due to the complexity of the system as well as the need to use suitable natural underground caverns as reservoirs.
L'invention est une "batterie à air comprimé" avec une entrée de puissance mécanique qui pourrait être mécaniquement couplée à n'importe quelle source d'énergie mécanique externe comme le vent ou l'hydroélectricité. La puissance mécanique est utilisée pour comprimer l'air et le forcer à travers un échangeur de chaleur vers un stockage submersible. La majeure partie de la chaleur générée lors de la compression serait stockée dans le liquide environnant. L'air comprimé est utilisé en même temps ou plus tard. L'air comprimé stocké passe dans un échangeur de chaleur lors de la détente, se terminant par un moteur à air submersible. La puissance mécanique créée est utilisée par d'autres appareils pendant que l'air est évacué et l'énergie thermique stockée est utilisée par l'air en expansion. L'ensemble est isolé d'un seul tenant de façon à limiter au maximum les échanges thermiques avec l'extérieur. Pratiquement, l'appareil agit comme une batterie physique qui stocke l'énergie mécanique et thermique d'entrée. Cette batterie pourrait aussi servir uniquement de réserve d'énergie thermique. Un générateur d'électricité pourrait convertir l'énergie mécanique de l'appareil en électricité. L'air comprimé pourrait également être utilisé directement par des dispositifs pneumatiques. Le système pourrait recevoir et stocker de l'énergie thermique de n'importe quelle source, comme l'énergie solaire thermique.
The invention is a "compressed air battery" with a mechanical power input that could be mechanically coupled to any external mechanical energy source such as wind or hydroelectricity. The mechanical power is used to compress air and force it through a heat exchanger to a submersible storage. Most of the heat generated during compression would be stored in the surrounding liquid. The compressed air is used at the same time or later. The stored compressed air passes through a heat exchanger during expansion, ending with a submersible air engine. The mechanical power created is used by other devices while the air is evacuated and the stored thermal energy is used by the expanding air. The whole is insulated in a single piece so as to minimize heat exchange with the outside. Practically, the device acts as a physical battery that stores the input mechanical and thermal energy. This battery could also serve only as a thermal energy reserve. An electricity generator could convert the mechanical energy of the device into electricity. Compressed air could also be used directly by pneumatic devices. The system could receive and store thermal energy from any source, such as solar thermal energy.
