Prospects for the Use of Thermal Storage in Municipal Energy Infrastructure.

One of the areas for increasing energy efficiency in the production of electrical and thermal energy is the use of cogeneration units (CGU), which is due to an increase in the share of useful heat output to heat supply systems. Large combined heat and power plants (CHPs), as a rule, use steam turbine units, which serve as sources of thermal energy for heating and hot water supply in cities with a high concentration of heat load. In small and medium-sized cities, the main sources of thermal energy are boiler houses. With the advent of modern gas piston and gas turbine units on the market, it is possible to predict the creation of mini-CHPs based on them. To increase their fuel efficiency, it is advisable to use seasonal thermal storage (TS) as part of the municipal energy infrastructure in order to reduce the volume of thermal emissions during the nonheating period.
