Shepherd (1993) derived a general expression for the available potential energy for compressible, hydrostatic flow, where the sum of this available energy and the kinetic energy is called pseudo-energy. He demonstrated that for a special basic state the small-amplitude limit of the generalized available potential energy reduces to the well

Abstract. There is an urgent global need for electrochemical energy storage that includes materials that can provide simultaneous high power and high energy density. One strategy to achieve this goal is with pseudocapacitive materials that take advantage of reversible surface or near-surface Faradaic reactions to store charge.
Herein, we design a novel Li-I2 energy storage system by inserting a nitrogen-doped graphene interlayer between the cathode and the separator. This interlayer allows the electrochemical reaction and pseudo-capacitive faradaic reaction to occur at the same reaction sites and helps the resultant battery achieve high electrochemical performance.

This article proposed the architecture of a stand-alone photovoltaic connected system (SPVS) with energy storage. An SPVS with energy storage requires power management for various operating modes. A coordinate controller is often necessary to manage the change in control architecture depending on the operating mode. This
Energy storage using reversible heat pumps is based on two closed cycles, indirectly connected by hot and cold thermal storage tanks.

Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
