Thermal energy storage
Le stockage d'énergie thermique (TES) utilise divers mécanismes pour une gestion efficace de la chaleur et une optimisation des performances. conception de produits et l'ingénierie.

Le stockage d'énergie thermique (SET) capte la chaleur ou le froid selon trois mécanismes fondamentaux : le stockage sensible dans des matériaux tels que l'eau, la roche ou le sel fondu ; le stockage latent par transitions de phase dans les matériaux à changement de phase (MCP) ; et le stockage thermochimique via des réactions réversibles dans les hydrures métalliques, les zéolites ou les systèmes à boucle de calcium. La capacité de stockage, l'efficacité des cycles de charge-décharge, la rétention d'exergie et la gestion des pertes thermiques définissent les performances du système sur des échelles de temps allant du tamponnage diurne au stockage intersaisonnier.

Les contextes d'intégration s'étendent solaire concentré Production d'énergie à partir de centrales à sels fondus à deux réservoirs, réseaux de chauffage urbain, récupération de chaleur résiduelle industrielle et refroidissement par absorption. Les régénérateurs à garnissage, les réservoirs à thermocline, les systèmes aquifères et de forage élargissent encore les possibilités de conception.
