Lehigh University researchers test concrete thermal battery for data center cooling
Researchers at Lehigh University have built a prototype concrete thermal battery capable of storing heat from data centers.
Prototype capacity and temperature limits
The fabricated system holds 150 kWh of stored energy. Testing confirms the unit can withstand temperatures up to 500 degrees centigrade during operation.
Heat recovery and efficiency results
This technology captures waste heat removed from computing equipment for later use. After a full charging and discharging cycle, the reported efficiency exceeds 70 percent.
Potential applications for stored energy
The recovered thermal energy supports flexible power generation and industrial processes. It also aids in reducing emissions and powering high-temperature solar thermal applications.
