HIGH-TEMPERATURE HEAT TRANSFER AND THERMAL ENERGY STORAGE MATERIALS
Low-melting, air-stable chloride salts replace costly molten salts for 750 °C heat transfer/TES at a fraction of the cost.
Researchers at Purdue University have developed a new alternative to molten salts for high-temperature heat transfer and thermal energy storage in concentrating solar power plants by integrating low-cost, low-melting chloride salts, which are resistant to oxidation, last long-term, and are reliable as they are chemically stable at 750oC. Traditional molten salts can cause air leaks, are often expensive, and must be closely monitored during use. By integrating the approach fine-tuned by Purdue researchers, energy production can now be streamed in pipelines and thermal energy storage (TES) tanks for nuclear power plants, hydrothermal power plants, and concentrating solar energy plants. In addition, simulation has shown that chloride-based salts are 8Xs less the cost of molten salts in operation.
