  • This form will search for any of the words you enter in a field, not the exact phrase you enter. If you would like to search for an exact phrase, put double quotes (") around the phrase. For example, if you search for Bike Path you will get results containing either the word Bike OR the word Path, but if you search for "Bike Path" you will get results containing the exact phrase Bike Path.

  1. Professor Yu-Feng Lin Featured on 'Wired' Article

    UIUC's Yu-Feng Lin was featured on a "wired" article. Andrew Stumpf explains, "The authors did a simulation for a residential district in Chicago. They don’t provide much detail about the geology and hydrogeology that is the basis for the geotechnical model. In Chicago, aquifer thermal energy storage (ATES) has yet to be used because groundwater is pretty scarce in the shallow subsurface and one would need to tap aquifers deeper in the bedrock. In the northern and western suburbs, the subsurface conditions in the glacial deposits is much better and I believe Kane County is looking into using the aquifers for a geothermal resource."

    Hi folks,

     

    Here is an update. Dom and Todd worked to get half of the hole grouted today and now wait until tomorrow morning to see if the battery floats, or not. Theoretically it should not, but we will see. They will start up again at 8 am if anyone is over that way. Xiaobing and Tony have gone back to Tennessee.

     

    Best,

  3. Project Announcement for UTB Installation

    Geothermal Battery at Energy Farm

    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
