This article highlights different research efforts to utilize thermal energy and thermal energy storage technologies. At several technical and panel sessions at the November ASME International Mechanical Engineering Congress and Exposition in Houston, there has been much discussion of cutting-edge work in thermal energy storage, including thermal energy storage materials, applications, and systems. Research into thermal energy storage is not limited to the confines of government and academia. Private companies are investigating whether they can incorporate thermal storage into some of their systems. Another potential advantage for solar thermal power is efficiency. Storing thermal energy as sensible heat is the most straightforward of the three methods, and the one that is the most widely deployed. A wide range of materials from simple concrete to synthetic oils has been tried for storing thermal energy. An energy storage system based on latent heat released as a material changes phase can be cost-effective. Thermal energy storage can become a game-changing technology wherever energy demand does not align exactly with energy supply. However, significant development challenges remain before these potential benefits can be realized.

This paper describes simulation-based results of a large-scale investigation of a commercial cooling plant including a thermal energy storage system. A cooling plant with an ice-on-coil system with external melt and a reciprocating compressor operating in a large office building was analyzed under four different control strategies. Optimal control as the strategy that minimizes the total operating cost (demand and energy charges) served as a benchmark to assess the performance of the three conventional controls. However, all control strategies depend on properly selected design parameters. The storage and chiller capacities as the primary design parameters were varied over a wide range and the dependence of the system’s cost saving performance on these parameters was evaluated.

Thermal Energy Storage System

Because of the capability of large capacity thermal storage and extended operation during night and cloudy days, concentrated solar thermal power generation is getting more and more attention in the recent years. Dual-media thermal energy storage system is typically adopted in industry for reducing the use of the heat transfer fluid, which is usually expensive. In such a dual-media system, the solid filler material can be a phase change material relying on latent heat or a regular solid material using sensible heat for energy storage. Two strategies of starting-up fluid charge and discharge are considered for the operation of a concentrated solar thermal power plant incorporated with a dual-media thermal storage system. These two strategies include: 1) starting daily cyclic charge and discharge operation with an initially cold tank; 2) to fully charge the thermal storage system before operation of the cyclic discharge/charge for the power plant. The energy storage efficiency and the effects to the power plant operation due to the application of these two strategies are studied in the current work based on an enthalpy-based 1-D model, and significant difference is found in starting-up process of the daily cyclic operations, which will help us decide the best strategy of operating a thermal energy storage system with more electrical energy output.
