Among the different ES technologies, compressed air energy storage (CAES) can store tens to hundreds of MW of power capacity for long-term applications and utility-scale. The increasing need for large-scale ES has led to the rising interest and development of CAES projects.
Advanced adiabatic compressed air energy storage (AA-CAES) is a large-scale and environmental-friendly storage technology that can supply heat and power. It can be adopted as an energy hub that integrates electricity and heating systems.
Starting in 1896, Paris used compressed air to power homes and industry. Beginning in 1978 with the first utility-scale diabatic CAES project in Huntorf, Germany, CAES has been the subject of ongoing exploration and development for grid applications. The U.S. Department of Energy (DOE) has a history of supporting CAES development.
One example they mention is precisely CAES. The IEA Technology Roadmap states that the key to achieving widespread storage technology deployment is enabling compensation for multiple services delivered across the energy system.
Compressed air has been used for mechanical processes around the world since 1870. Buenos Aires, Argentina, used air pulses to move clock arms every minute. Starting in 1896, Paris used compressed air to power homes and industry.
During heat purchase periods, the maximum bidding demand is 45 MW. And during heat selling periods, the heating capacity bidding range is 0, 30 MWh. The proportion of flexible demands is ρ = 0. 4 for both the EH and general consumers in the heating market.
