Most underground thermal energy storage systems involve storage of heat at temperatures between 50 and 95 C [128]. Direct use of hot water for heating requires lower temperatures (50 °C), while a temperature difference of at least 35 °C must be maintained to operate an efficient binary cycle power plant for thermo-electrical conversion.
Latent heat storage systems store energy without the medium changing in temperature but rather depends on the changing state of a medium. So called ''phase change materials'' have been developed, which can store
Waste heat minimisation and recovery is a significant opportunity to improve efficiency and reduce energy bills. It can also mean lower maintenance costs and improved equipment productivity as energy-using equipment can be operated less intensely. There are often numerous opportunities in older buildings and plants to implement heat recovery
