Below is a message from Andrew Stumpf regarding the installation of the underground thermal battery at the UIUC Energy Farm:

Dear colleagues,

It is with great excitement that I can announce the project to install Underground Thermal Battery (UTB) system developed by Dr. Xiaobing Liu’s team at Oakridge National Laboratory at UIUC Energy Farm will begin next week. This will be a several weeks project that includes installing the UTB, associated geothermal boreholes, geothermal heat pump, HVAC upgrades and control center. On Monday the UTB will be placed in the ground. Skinner Drilling will be installing the UTB with assistance from Durbin Geothermal. All the other work will follow over the coming weeks. I expect drilling will start between 8:00 and 8:30 and take about 1 hour, and then the battery will be lowered into the ground and be done before noon.

You're most welcome to visit.

Best,

Andy
