  • Using Saline or Brackish Aquifers as Reservoirs for Thermal Energy Storage

    Tools to evaluate reservoir thermal energy storage (RTES; heat storage in permeable zones that underlie well-connected regional aquifers) are developed and applied to the Columbia River Basalt Group (CRBG) beneath the Portland Basin, Oregon, USA. The performance of RTES for heat storage and recov...

  • Community-scale Geothermal Energy Systems (E-Poster)

    Much of the focus surrounding geothermal energy resource utilization has been on high enthalpy resources for electrical power generation – these systems are typically restricted to regions with high heat flow. However, there exists a much more extensive set of geothermal resources that can be emp...

  • Energy Storage Coupling System of Low-cost Geothermal Heating (E-Poster)

    With the increasingly serious environmental pollution, the utilization of clean resources such as geothermal energy is gradually increasing. Building heating is the main application mode of geothermal energy, but the existing geothermal energy heating system is mainly based on a single mode. Its ...

  • Rapid Geothermal District Heating Assessments (E-Poster)

    Fourth generation district heating (4GDH) materials technology and methods are making previously uneconomic conventional geothermal resources feasible for district heating development. Numerous low-temperature conventional geothermal resources exist near communities in the Western United States. ...

  • Groundwater Flow and Heat Transport Modelling at Zeta Valley Aquifer (E-Poster)

    An intergranular aquifer in the Zeta Valley (Montenegro) represents one of the largest groundwater reservoirs in the region. The depth to the water table is around 20 m on average, so the temperature of the groundwater remains almost constant throughout the year (around 14°C). The quantitative an...

  • Ground-source Heat Exchangers for Cooling Applications in Hawai‘i (E-Poster)

    We investigate the potential of ground source heat exchangers (GSHE) for HVAC, particularly in cooling applications, in the tropical environment of Hawai‘i. Recent studies in Southeast Asia showcase the capacity of GSHE for space cooling in tropical environments (Yasukawa and Uchida, 2018). In Ha...
