High temperature heat pump energy storage system design

Can high temperature heat pumps be integrated into pumped thermal energy storage systems?

The model concerned high temperature heat pumps integrated into pumped thermal energy storage systems with discharge temperatures below 160 °C and sink temperatures above 60 °C.

What is a high-temperature heat pump (HTHP)?

High-temperature heat pumps (HTHPs) are electrically powered systems that supply heat above 90°C. HTHPs have the potential to serve two valuable functions in United States (U.S.) industry. First, by valorizing and elevating waste heat streams, HTHPs can improve industrial energy efficiency.

What is the application scenario of high-temperature heat pumps?

Finally, the application scenario of high-temperature heat pumps is prospected. In addition to the application of industrial heating, it is often used for heat storage to improve the regulatory characteristics of the system. The new heat pump electricity storage system has great application potential in the field of renewable energy consumption.

Can high-temperature heat pumps improve industrial processes?

Higher temperature heat pumps offer significant potential to enhance thermally demanding industrial processes due to their high temperature lift capability. This review looks at how future improvements in HTHP technology can take use of breakthroughs in high-temperature heat pump research to address important technical obstacles.

What are high-temperature heat pumps used for?

As reported in Arpagaus et al. , high-temperature heat pumps have the potential to be used in various applications, including hot water supply, plastics, textiles, wood, construction, beverages, cement, food, paper, metal, energy storage, and chemical industries. Fig. 8 shows possible heat sources for HTHPs in industry.

What are the development prospects of high-temperature heat pumps?

Based on the above analysis of high-temperature heat pumps, four development prospects are put forward: low-Global-Warming-Potential (GWP) working fluid; cycles of temperature lift greater than 80 °C; a compressor with better high-temperature performance; and circulation characteristics of heat pump electricity storage. 1.
