Study on Molten Salt Phase Change Material Application in Stirling Engine

One of the most important economic challenges, affecting nations, officials, economies, and individuals, is energy. Fossil fuels, such as coal, oil, and natural gas, have long been the primary energy sources used in energy production. emissions from fossil fuels in the long term can accelerate global environmental deterioration and climate change. The development of renewable energy and energy storage technology as an alternative to fossil fuel needs to be done immediately. This article discusses the use of molten salt-based thermal energy storage for storing thermal-based renewable energy such as solar energy. Examples of molten salts based on nitrate, chloride, fluoride and carbonate for thermal storage media at various working temperatures, applications and thermophysical properties are discussed in this article. The conversion of thermal energy to electrical energy using a Stirling engine is also discussed in this article. Several proposed systems, designs, and performance for converting heat energy to electricity using the Stirling engine are introduced and discussed in this article. The prototype Stirling-molten salt system has been analyzed and is available in several studies. As a result, molten salt capability to supply heat over a long period of time and affects the performance of the heat-to-electricity conversion by the Stirling engine.
