Almacenamiento de energía en aire comprimido
El almacenamiento de energía mediante aire comprimido aprovecha la compresión de aire subterránea para una gestión energética eficiente y una respuesta eficaz a la demanda máxima.

El almacenamiento de energía mediante aire comprimido (CAES, por sus siglas en inglés) convierte el excedente de energía eléctrica en energía mecánica comprimiendo el aire en formaciones geológicas subterráneas (cavernas de sal, acuíferos o depósitos de roca porosa) y recuperándolo a través de turbinas de expansión durante los períodos de máxima demanda.

Termodinámica El rendimiento depende de la etapa de compresión y expansión, el enfriamiento intermedio, la recuperación y la integración del almacenamiento térmico, distinguiendo variantes diabáticas, adiabáticas e isotérmicas con eficiencias de ciclo completo sustancialmente diferentes. La integridad geomecánica del medio de almacenamiento, el sellado del pozo y los procesos de lixiviación de la caverna determinan la viabilidad operativa a largo plazo. La investigación actual se centra en configuraciones adiabáticas avanzadas que eliminan la combustión por completo, enfoques isotérmicos que reducen las pérdidas de exergía y la optimización del despacho de la red.

Esta página recopila las publicaciones revisadas por pares más recientes y las patentes concedidas en todo el espectro técnico de la investigación en CAES.

A CFD&ndash;DEM Numerical Study

Published on 2026-01-29 by Weiqiang Zhao, Xijie Song, Ning Wang, Yongyao Luo, Ling Ma @MDPI

Abstract: During the discharge process of a salt cavern compressed air energy storage (CAES) system, high-speed air flow may entrain salt slag from the cavern floor, posing a threat to pipeline safety. Currently, there is a lack of in-depth research into the transient mechanisms of the entrainment process, particularly the influence of particle shape. This study employs a CFD-DEM coupling approach to conduct, for the first time, a high-fidelity simulation of slag entrainment dynamics during the initial di[...]

Published on 2026-01-24 by Pasquale M. Sforza @MDPI

Abstract: Normal shock pressure ratios in equilibrium air for Mach numbers up to 30 and altitudes to 300,000 feet are shown to be correlated by a simple power law which provides an accuracy of &amp;plusmn;2%, thereby permitting direct calculation of corresponding enthalpy ratios accurate to &amp;plusmn;1% without iteration; a slight change in power-law coefficients extends this capability to Mach 65. Temperature, density, and compressibility may be then found directly from tables for high temperat[...]
