Title: Feasibility Study of Large-Scale Energy Storage in the Earth

Abstract

Energy storage systems on a large scale are needed when there is a mismatch between electricity generation and demand rates. The mismatch may be due to a variety of reasons: 1. Generation rates of solar are cyclic and are often out of phase with the demand cycles. 2. Generation rates of wind are unpredictable. Furthermore, high-efficiency, low-carbon power plants (e.g., nuclear) typically have high capital cost and low operating cost. Such plants are designed for continuous base-load operation and require a high capacity factor for economic viability (Forsberg, 2017). For these reasons, it is advantageous to be able to store energy when not needed and use it when needed. Our proposed process, called the Air Earth Battery, has been developed to accomplish the task of energy storage and dispatch, using a combination of compressors, expanders, heat exchangers, and subsurface porous, permeable rock formations. This technology utilizes two issued U.S. Patents (Buscheck, 2017a; 2017b), one filed U.S. Patent Application (Buscheck, 2017c), and one filed U.S. Provisional Patent Application (Buscheck and Upadhye, 2018).
