Abstract

In the current study the feasibility of using concentrated solar power (CSP) coupled with thermal energy storage (TES) to displace gas for heating was explored. To assess the feasibility, a numerical model of an air-based encapsulated phase change storage system was developed, validated, optimised, and economically costed. The optimised air-based EPCM system utilised a high and low melting temperature PCM with a sensible filler. It was found that a capsule radius of 10 mm and PCM volume of 13 % resulted in the lowest cost of discharged energy of $25.55/kWht. This system was then coupled to typical meteorological year (TMY) solar data for Adelaide, South Australia, to simulate performance of a 1 MWt heat load over a year. By solving an hourly system generation and demand profile, it was found that the system could provide an economical alternative to gas when the gas price was $20/GJ for a variety of demand profiles
