What is compressed air energy storage (CAES)?
Introduction Compressed Air Energy Storage (CAES) has emerged as one of the most promising large-scale energy storage technologies for balancing electricity supply and demand in modern power grids. Renewable energy sources such as wind and solar power, despite their many benefits, are inherently intermittent.
What is a heat storage unit?
Heat storage units (thermal energy storage units, latent heat storage units), in particular metal-based high-temperature storage units, can make the operation of industrial cogeneration plants more flexible by storing process heat and providing process steam. Operators can thus save costs for fuels in auxiliary boilers.
