Thermal Storage Material and Thermal Storage System for High Temperature Heat Storage

Can be stored at 300 to 700℃ for several hours

Higher temperature heat can be stored at the lower costs and the smaller footprints than existing technology

 

Client / Market

• Industrial plant with high temperature waste heat
  
• Concentrated solar power generation system
  
• Other systems that require high temperature heat storage

 

Necessity of this Technology

• The commercial molten salt used thus far starts to decompose at above 550℃ so that it cannot be used for higher temperature applications.
  
• Other candidate materials are unstable or can be melt at high temperature, above 400℃, which make it difficult to use them in a large scale system.
  
• Existing heat storage systems use two storage tanks of hot and cold temperature resulting in the higher capital cost.
  
• Domestic institutes or companies have not experienced this kind of high temperature heat storage systems.

 

Technical Differentiation

• Can transfer the heat at atmospheric temperature and store it at 300 to 700℃ for several hours
  
• Maintains the high temperature heat source so that the heat storage and conversion efficiency can be increased
  
• Using the thermocline single tank reduces the required footprint for the system lowering the capital cost
  
• Cost of heat storage materials can be reduced
