Thermal energy storage
O armazenamento de energia térmica (TES) utiliza diversos mecanismos para o gerenciamento eficiente do calor e a otimização do desempenho no projeto e na engenharia de produtos.

O armazenamento de energia térmica (AET) captura calor ou frio por meio de três mecanismos fundamentais: armazenamento sensível em materiais como água, rocha ou sal fundido; armazenamento latente por meio de transições de fase em materiais de mudança de fase (PCMs); e armazenamento termoquímico via reações reversíveis em hidretos metálicos, zeólitas ou sistemas de ciclo de cálcio. A capacidade de armazenamento, a eficiência dos ciclos de carga e descarga, a retenção de exergia e o gerenciamento de perdas térmicas definem o desempenho do sistema em escalas de tempo que variam do armazenamento diurno ao armazenamento intersazonal.

Os contextos de integração abrangem energia solar concentrada com configurações de dois tanques de sal fundido, redes de aquecimento urbano, recuperação de calor residual industrial e refrigeração por absorção. Regeneradores de leito fixo, tanques de termoclina, aquíferos e sistemas de poços artesianos ampliam ainda mais o espaço de projeto.
