Geothermal phase change energy storage

In geothermal energy storage systems, phase change materials play a crucial role by storing excess thermal energy generated from geothermal sources. When the geothermal system produces more heat than needed, the PCMs absorb this energy and store it as latent heat during phase changes. [pdf]

Energy storage materials geothermal

This technology plays a crucial role in improving efficiency and enabling year-round utilization of geothermal resources, bridging the gap between energy production and demand. Various types of geothermal storage systems exist, including borehole thermal energy storage, aquifer thermal energy storage, and underground thermal energy storage [pdf]

Geothermal well energy storage

“It can't just be any hole in the ground,” explained Augustine, a researcher with NREL’s geothermal research group. The idea is to use depleted oil and gas wells as a reservoir for the storage of compressed natural gas. As needed, the gas can be released to spin a turbine and generate electricity. [pdf]
