Presentation: Underground Thermal Energy Storage: A Not-So-New Resource for Supply/Demand Flexibility and Energy Resilience in the U.S. Energy Transition
Presenter: Ryan Cahalan, Ph.D.; Research Geologist, U.S. Geological Survey (USGS)
About Our Presenter:
Ryan is a research geologist with the GMEG Science Center in Portland, Oregon. Since joining the USGS in 2020, Ryan has devoted his career to studying shallow geothermal energy and volcanic systems. Presently, his research focuses on modeling heat recovery in underground thermal energy storage (UTES).
Ryan Cahalan joined the USGS after completing a PhD at the University of Oregon on modeling multiphase transport in water-rich volcanic eruptions. His first project with the USGS was in collaboration with Cascades and Hawaiian Volcano Observatories, studying the December 2020 Kīlauea Volcano eruption focusing on the interaction of the erupted lava and the summit water lake. In November 2022, Ryan joined the Geothermal Resource Investigations Project (GRIP) where he applies his flow modeling background to new problems in underground thermal energy storage. Ryan is also the Powell Center Fellow for the City-scale Geothermal Energy Project.
About Our Presentation: The United States has defined goals to de-carbonize the energy sector, though incentives to do so vary state-by-state. One promising de-carbonizing energy option for cities focuses on their heating and cooling needs, which constitutes around one-third of U.S. and one-half of European energy. If heating and cooling loads can be met by geothermal direct-use technologies, then the need for new electric sources can be greatly lessened. Despite the proven efficacy of geothermal energy as a district-scale heating and cooling resource in Europe and elsewhere, it is currently only a niche resource in the heating and cooling sector, though has significant potential for future growth in the US. Historically, emphasis has been placed on geothermal electricity generation potential that requires higher temperature (greater than 90 °C) resources at drillable depths, but potentially viable areas are geographically limited and typically well removed from urban centers. In addition, the increased prominence of renewable electricity sources, such as wind and solar onto city-scale electric grids, has led to new urgency around questions of energy storage. Underground thermal energy storage (UTES), wherein surplus or waste heat is stored underground for later use, presents a long-duration energy storage solution. Within the suite of UTES technologies, there is an option for nearly any set of hydrogeologic conditions. I will overview the advantages and limitations of UTES across the US, highlight examples of working installations in Europe and promising advancements in the US, and showcase the USGS UTES team's progress toward nationwide UTES resource assessments.
Directions to North Lake Dallas College, 5001 North MacArthur Boulevard, Irving, TX 75038:
Via the Walnut Hill Lane main entrance:
Enter on North Lake College Boulevard at the west side of the campus. Turn right at the stop sign into a parking lot. Building C will be ahead when you're at that stop sign, on the southwest side of Liberty Circle (with the flagpoles). There is handicap parking in the lot closest to Building C.
Via the MacArthur Boulevard east entrance:
From Interstate 635 or Highway 114, take MacArthur Boulevard southward.
From Interstate 30 or Highway 183, take MacArthur Boulevard northward.
The North Lake campus entrance is a short distance south of the DART Orange light rail line overpass across MacArthur Boulevard. Don't enter the light rail stop! Follow the main road to the left. At the stop sign, turn right and follow that road to the next stop sign. Liberty Circle (with the flagpoles) will be on your left, and Building C will be ahead. Continue ahead into the lot in front of Building C. Handicap parking is along the northeast side of the parking lot.
