Compressed-air energy storage
OverviewHistoryTypesCompressors and expandersStorageEnvironmental ImpactProjectsStorage thermodynamics
Citywide compressed air energy systems for delivering mechanical power directly via compressed air have been built since 1870. Cities such as Paris, France; Birmingham, England; Dresden, Rixdorf, and Offenbach, Germany; and Buenos Aires, Argentina, installed such systems. Victor Popp constructed the first systems to power clocks by sending a pulse of air every minute to change their pointer arms. They quickly evolved to deliver power to homes and industries. As of 1896, the Paris system had 2.2 MW of
