압축 공기 에너지 저장(CAES)은 잉여 전기 에너지를 지하 지질 구조(소금 동굴, 대수층 또는 다공성 암석 저장소)에 공기를 압축하여 저장한 후, 최대 수요 시 팽창 터빈을 통해 회수함으로써 기계적 에너지로 변환합니다.
Thermodynamic performance hinges on compression and expansion staging, intercooling, recuperation, and thermal store integration, distinguishing diabatic, adiabatic, and isothermal variants with substantially different round-trip efficiencies. Geomechanical integrity of the storage medium, wellbore sealing, and cavern leaching processes govern long-term operational viability. Current research targets advanced adiabatic configurations eliminating combustion entirely, isothermal approaches reducing exergy losses, and grid-dispatch optimization.

Scroll compressor
Patent published on the 2026-09-10 in WO under Ref WO2026186952 by LG ELECTRONICS INC [KR] (Park Sangbaek [kr], Jung Seongmun [kr], Kim Cheolhwan [kr])
Abstract: A scroll compressor is provided. The scroll compressor is configured such that a fixed wrap comprises a fixed wrap portion and an extension wrap portion extending from a discharge end of the fixed wrap portion and having a wrap height lower than a wrap height of the fixed wrap portion, wherein a wrap accommodation groove in which the extension wrap portion is rotatably accommodated is formed between the outer circumference of a rotary shaft insertion portion and the inner circumference of an orb[...]
Our summary: A scroll compressor features a fixed wrap with an extension wrap that has a lower height. This design improves wrap strength and reduces tipping moments while minimizing leakage between compression chambers. The variation in wrap heights also mitigates inter-wrap frictional loss and abrasion from corner protrusions.

A CFD–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[...]

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 ±2%, thereby permitting direct calculation of corresponding enthalpy ratios accurate to ±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[...]
