Our Research Areas
INL’s geothermal portfolio brings together complementary research areas that expand the use of Earth’s subsurface resources. Explore the laboratory’s work in geothermal energy and storage, geologic hydrogen and critical materials.
Geothermal Energy and Storage
Geothermal energy storage uses the Earth’s subsurface as a natural battery—storing heat or energy underground and delivering it when it’s needed most. This approach supports long-duration energy storage and strengthens grid resilience.
Geologic Hydrogen
Hydrogen is an adaptable, versatile and abundant source of energy. Most hydrogen comes from industrial processes, which can be energy-intensive to produce. Geologic hydrogen forms within Earth’s crust. This largely untapped resource is estimated to cost less than $2 per kilogram in the United States.
Critical Materials
Critical materials must be characterized before extraction, separation and use. INL uses advanced analytical instruments to detect, quantify and characterize critical materials in natural waters, tailings, recycled materials and more.
