The air storage pressure of the compressed air energy storage system gradually decreases during the energy release process. In order to make the turbine work efficiently in non-design conditions, it is necessary to adopt a reasonable air distribution method for the turbine.
Argonne''s thermal energy storage system, or TESS, was originally developed to capture and store surplus heat from concentrated solar power facilities. It is also suitable for a variety of commercial applications, including desalination plants, combined heat and power ( CHP) systems, industrial processes, and heavy-duty trucks.
Their new demonstrations show that it converts heat to electricity with over 40 percent efficiency — a performance better than that of traditional steam
Steam Turbine. In general, a steam turbine is a rotary heat engine that converts thermal energy contained in the steam to mechanical energy or to electrical energy. In its simplest form, a steam turbine consist of a boiler ( steam generator ), turbine, condenser, feed pump and a variety of auxiliary devices. Unlike with

Emission free compressed air powered energy system can be used as the main power source or as an auxiliary power unit in vehicular transportation with advantages of zero carbon emissions and improved the overall energy efficiency of the integrated energy system.
The main steam and reheat steam provides the energy storage mode for Case 3 as shown in Fig. 4. 350 t/h and 205 t/h of main steam and reheat steam are extracted respectively, both at a temperature of 538 °C. The cold salt tank discharges 2500 t/h of cold salt at 250 °C and is diverted by a three-way valve to the condenser and ME2

The integration of a novel steam storage system into the plants process enables a decoupling of the steam (boiler) and the power generation (steam turbine). By buffering the steam, the power output of the turbine can be adjusted without changing the rated thermal capacity of the plant.
A heat engine that extracts thermal energy from pressurized steam by expansion over several stages to do mechanical work on a rotating output shaft. The basic operation of a steam turbine is similar to that of the gas turbine. The ideal (theoretical) steam turbine is considered to be an isentropic process, or constant entropy process, in which
