Geologic energy storage is a practical solution that can store 100 or more hours of energy. Batteries are primarily designed for storing electrical energy, but geologic storage methods have an advantage of being able to store chemical and thermal energy (for space heating, for example) directly without conversion to electricity.
We present an approach that uses the huge fluid and thermal storage capacity of the subsurface, together with geologic carbon dioxide (CO 2) storage, to harvest, store, and dispatch energy from subsurface (geothermal) and surface (solar, nuclear, fossil) thermal resources, as well as excess energy on electric grids.
Much of the technol-ogy for geologic energy storage is still undergoing research and development (Crotogino and others, 2017; Matos and others, 2019), although several industrial-sized underground storage projects are already operating in the United States and world-wide (fig. 1).
The initial research goal is to compile a report containing recommendations on the geologic datasets needed and the key process steps required to build a probabilistic assessment methodology to assess various geologic subsurface energy storage options.
