Energy Storage Systems Electrochemical Systems Batteries are available in an increasing Energy Storage number of chemistries, including lead-acid, Energy storage systems can provide beneficial solutions to nickel-cadmium, lithium-ion and sodium/ the challenges faced by renewable power generation grid sulfur. Battery systems are inherently integration. Ensuring power during periods of high demand, modular and have a wide range of enhancing grid reliability, and smoothing intermittent supply applications. fluctuations are a few of the roles filled by energy storage in the drive towards a more efficient electrical grid. Compressed Air Energy Storage CAES utilizes off-peak electricity to Applications and Benefits compress and store air for expansion Energy storage systems are available in a variety of and generation during high demand, high technologies that are optimally selected for predictable pricing periods. Large CAES plants require benefits as well as the transmission system and electrical geologically-specific locations and provide generation plant they will support. Electrochemical, benefits similar to a peaking plant. compressed air with preferred storage reservoir, and flywheel Flywheels systems are three of the developed technologies that can be utilized to provide energy time-shifting, electric supply Flywheel storage employs magnetic capacity, load following, transmission and distribution upgrade levitation to spin a cylinder on a shaft deferral, time-of-use energy cost management, demand and generate electricity.
