Název v původním jazyce
Design and optimization of non-supercritical CO2 thermal power cycle for "P2H2P" energy storage system
Popis výsledku v původním jazyce
Most of the current research and development of CO2 cycles for power to heat heat to power (P2H2P) energy storage systems are focused on application s of supercritical CO2 cycles . However, this work is focused on alternative application of CO2 power cycle with standard ( i.e., non supercritical) cycle and modified industrial turboexpander s as main working machine s . Thermal Cycle for power storage system with thermal energy accumulator for energy storage and non supercritical CO2 power cycle for backward production of electricity is described i n this paper The CO2 cycle is compared with Nitrogen cycle with same parameters as well . Initially the thermal accumulator design , option of accumulation media (molten salts or liquid metals) and its parameters are described. The main part of the paper is focused on non supercritical CO2 power cycle s . Possible configurations of cycle, design aspects of main parts of cycle possibilities of efficiency improvement are discussed ; such as regeneration or intercooling. Finally , advantages and disadvantages of this CO2 and N2 cycle are discussed and compared. The concluding result of this paper is a very similar efficienc y of the two working fluid s at the selected parameters.
