Are phase change materials suitable for thermal energy storage?
Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.
What is energy storage technology?
Energy storage technology is one tool that can increase the value and reduce the cost of all renewable energy supplies. Concentrating solar power (CSP) technologies have the ability to dispatch electrical output to match peak demand periods by employing thermal energy storage (TES).
How can thermal energy storage help commercial solar power plants?
Energy can be stored at relatively high efficiencies in the form of thermal energy. Thermal energy storage (TES) increases plant capacity factors and improves dispatchability. Reducing the capital cost of TES technologies will also result in a reduced cost of energy and ultimately serve as an enabler for commercial solar power plants .
What are the design principles for improved thermal storage?
Although device designs are application dependent, general design principles for improved thermal storage do exist. First, the charging or discharging rate for thermal energy storage or release should be maximized to enhance efficiency and avoid superheat.
What is a heat exchanger?
The heat exchangers are the largest cost system component. They not only facilitate the transfer of energy from the HTF to the PCM, but also contain the PCM. The heat exchangers used in this project are based on prefabricated heat exchangers that can be shipped to the site.
What is a dynamic thermal storage strategy?
For example, combined heat and power (CHP) systems for recovering and using waste heat can synchronously generate electricity and heat.86 To regulate the heat load from the CHP system, a dynamic thermal storage strategy is desired to enable an enhancement by considering the transient waste heat and dynamic electricity generation.
