Title (EN) SYSTEM FOR DIRECT ELECTRICAL CHARGING AND STORAGE OF THERMAL ENERGY FOR POWER PLANTS
(FR) SYSTÈME DE CHARGE ÉLECTRIQUE DIRECTE ET DE STOCKAGE D'ÉNERGIE THERMIQUE POUR CENTRALES ÉLECTRIQUES
Abstract:
(EN) System for storage of electricity in the form of thermal energy, and release of thermal energy during times of demand. The system includes a unit for containing at least one electrically conducting phase change material and electrical circuitry for driving electrical current through the phase change material to heat the phase change material into a molten state, or at least one electrical heater used to convert electricity into heat stored in the phase change material. Structure is provided for transferring heat in the phase change material to a working fluid such as steam or gas for electricity generation in a steam turbine or gas turbine, capable of generating supercritical fluids. Structure is also provided for transferring heat in the phase change material to a thermal energy to electrical energy conversion device. A suitable phase change material is elemental silicon or an aluminum-silicon alloy.
(FR) L'invention concerne un système de stockage d'électricité sous forme d'énergie thermique et de libération d'énergie thermique pendant des temps de demande. Le système comprend une unité pour contenir au moins un matériau à changement de phase électriquement conducteur et un circuit électrique pour faire passer un courant électrique à travers le matériau à changement de phase pour chauffer le matériau à changement de phase dans un état fondu, ou au moins un chauffage électrique utilisé pour convertir l'électricité en chaleur stockée dans le matériau à changement de phase. Une structure est destinée à transférer de la chaleur dans le matériau à changement de phase à un fluide de travail, tel que de la vapeur ou du gaz, pour la génération d'électricité dans une turbine à vapeur ou une turbine à gaz, pouvant générer des fluides supercritiques. L'invention concerne également une structure destinée à transférer de la chaleur dans le matériau à changement de phase en une énergie thermique à un dispositif de conversion d'énergie électrique. Un matériau à changement de phase approprié est le silicium élémentaire ou un alliage aluminium-silicium.
