Projects Updates for collection: Renewable Energy Projects

  1. Net Metering on campus

    Associated Project(s): 
    ECE Rooftop Solar PVs
    Rooftop Solar Potential

    For all of our buildings with renewable energy systems, we employ a net metering method.  We deduct the energy supplied by the system from the building load on the campus grid.  So, if ECE uses about 250,000 kwh of electricity per month, and the rooftop array will supply 10,000 kwh per month, then the net bill for the ECE building will be 240,000 kwh at the campus electricity rate.  Therefore, the building gets full credit for the energy supplied by the array.

  3. Geothermal monitoring borehole on the Bardeen Quad

    Associated Project(s): 
    Geothermal Monitoring Well on Bardeen Quad

    Hi everyone,

    I wanted to report that yesterday we completed the thermal response test in the borehole, and our work at the site is done. Currently, we are working on processing and analyzing the data. This work should be completed later this week, and when done we will share the results with Sachin and the rest of the project team.

    Tim Stark will also use these results to compare with the wellbore model his student is developing.

     

    Best,

    Andy

  10. Washington Post article: The next money crop for farmers: Solar panels

    Associated Project(s): 
    Solar Farm 1.0
    Issue Press Releases and Sustainability Reports

    The Washington Post published an article on February 22, 2019, about how farmers are making the transition to solar based on current corn and soybean price drops, and the implications of that. Evan DeLucia is quoted in this article.

  13. SSC funds Energy Shaft at the Energy Farm

    Associated Project(s): 
    Geothermal on Campus
    Student Sustainability Committee (SSC)

    This student-led project will involve the design, construction, and installation of an energy geo-structure for heating the UIUC Energy Farm, located near the southeast corner of Race Street and Curtis Road on the South Farms. This project has great potential in exploring and utilizing geothermal energy, a renewable energy alternative to fossil fuels. An energy shaft is a new technology designed to access the shallow geothermal energy (relatively constant ground temperature in the upper 30 m of the subsurface). The objective of the project is to determine the feasibility of using drilled shafts that are already being used to support structures on campus also as a geothermal heat-exchange element. Geothermal heat exchangers (closed absorber pipes) can be incorporated into underground infrastructure, e.g., drilled shafts, through which water is circulated to withdraw shallow geothermal heat (~55 °F) and transport it to the surface for structure heating or cooling.

  16. SSC funds Gable Home

    Associated Project(s): 
    Student Sustainability Committee (SSC)
    Illinois Solar Decathlon

    The Gable Home was designed and built by students to compete in the 2009 US Dept. of Energy's Solar Decathlon Competition. Following the competition, the house returned to campus and was located at the I Hotel until Spring 2017 at which point it had to be moved due to the expansion of the research park. Since then a team of students and faculty have been working on finding a new permanent location for the Gable Home. A suitable location was found at the Energy Farm on Race St. in Urbana. The house is a valuable educational tool for students from many units on campus to visit and experience occupying a space that is powered solely by the sun and uses passive and active systems to create desirable thermal comfort throughout the year. This SSC grant provides support for the installation costs to make Gable Home a permanent fixture at the Energy Farm, so it meets building codes.

  18. Fiber-optic cable intact

    Associated Project(s): 
    Geothermal Monitoring Well on Bardeen Quad

    Hi everyone,

    I can report today that the fiber-optic cable is intact and the test returned a signal along the entire 235 m cable. What you see in the photograph is data along the cable going down and coming back up (470 m total).

    We have ordered the drop box to store the fiber-optic cable, and a hole has been dug for it. The box will be installed by F&S after the holidays. The fencing is being left around the site until this is done.

    Wishing you all the best this holiday season.

    Andy

  19. Borehole sealed

    Associated Project(s): 
    Geothermal Monitoring Well on Bardeen Quad

    Hi Everyone, We successfully installed the geothermal loop and fiber optic cable today. The borehole is now grouted closed. My appreciation goes out to the group of colleagues and staff from the ISGS that assisted the drill crew to insert the 400-feet of tubing in the ground.

    The drill crew will be back in the morning to clean up the site and move equipment offsite. We still need to install a drop box to store the fiber-optic cable and access the geothermal loop. The box has been ordered and if it arrives in the morning, we may be able to get it installed before the holidays. In about a month we will start measuring the ground temperature and run a DTRT test once the grout cures.

    Happy Holidays!!

    Andrew

  20. Installing fiber optics

    Associated Project(s): 
    Geothermal Monitoring Well on Bardeen Quad

    Hi everyone, We had a successful day of collecting geophysical logs in the borehole. I have seen print outs of this excellent data, and is an important part of the geologic characterization. Thanks goes out to Tim Young for coming out of retirement to help us complete the work.

    Tomorrow we will install the U-bend and fiber-optic cable in the borehole. Our task is to sink a 400-foot log tube filled with water (weighing ~600 lbs) down the hole. For those nearby you may want to drop by for a visit. Once this is done, we will proceed to grout the borehole closed.

    Cheers,

    Andy
