The design and analysis of a hydro-pneumatic energy storage
Considering the hydraulic system, energy efficiency can be increased by reducing throttling losses and energy storage/re-utilization. There are two ways to store the potential/kinetic energies, including electric and hydraulic energy regeneration systems (EERS and HERS) [3, 4].The EERS usually contains a hydraulic motor, generator,

Compressed-air energy storage
OverviewTypesCompressors and expandersStorageHistoryProjectsStorage thermodynamicsVehicle applications

Compressed-air energy storage (CAES) is a way to store energy for later use using compressed air. At a utility scale, energy generated during periods of low demand can be released during peak load periods. The first utility-scale CAES project was in the Huntorf power plant in Elsfleth, Germany, and is still operational . The Huntorf plant was initially developed as a load balancer for fossil-fuel-generated electricity
