The Pacific Northwest Laboratory (PNL) conducted an assessment of the adiabatic compressed air energy storage (CAES), hybrid CAES, CAES with coal gasification, and CAES with pressurized fluidized bed combustion concepts based on information provided in conceptual design studies.
The description of the concepts can be found in Kato (2007) and (Cabeza, 2012) and in Chapter 1, Introduction to Thermal Energy Storage Systems, of this book. Heat/cold storage in ATES consists of extracting groundwater from a well, heating/cooling this water with an available heat/cold source, and then re-injecting it back into the aquifer
What Is Energy Storage? "Storage" refers to technologies that can capture electricity, store it as another form of energy (chemical, thermal, mechanical), and then release it for use when it is needed. Lithium-ion batteries are one such technology. Although using energy storage is never 100% efficient—some energy is always lost in
Solid chemisorption technology is an effective form of energy conversion for recovering low-grade thermal energy, but limited thermal conductivity and agglomeration phenomena greatly limit its performance.
