GLIDES is a modular, scalable energy storage technology designed for a long life (>30 years), high round-trip efficiency (ratio of energy put in compared to energy retrieved from storage), and low cost. The technology works by pumping water from a reservoir into vessels that are prepressurized with air (or other gases).
The target formation for CO 2 storage in Sleipner project is the Utsira sandstone reservoir with eight intralayer shales and 50 m of shale as caprock (Chadwick et al., 2012; Eiken, 2019). The caprock prevents CO 2 from leaking upwards and ensures the permanence of CO 2 storage (Bickle, 2009; Song and Zhang, 2013; Vilarrasa and Carrera, 2015).

The results of the Fenton Hill EGS project demonstrated the potential for in-reservoir energy storage (IRES) in such systems, wherein accumulated geofluid and reservoir pressure are used to shift the output of a geothermal plant from one time to another. Importantly, the ability to store energy in this manner is an inherent property of an EGS ...
The concept of reservoir thermal energy storage (RTES), i.e., injecting hot fluid into a subsurface reservoir and recovering the geothermal energy later, can be used to address the issue of imbalance in supply and load because of its grid-scale storage capacity and dispatchable nature [2]. Note aquifer/geological thermal energy storage (ATES ...
