The power of a storage system, P, is the rate at which energy flows through it, in or out. It is usually measured in watts (W). The energy storage capacity of a storage system, E, is the maximum amount of energy that it can store and release. It is often measured in watt-hours (Wh). A bathtub, for example, is a storage system for water.
Toward that end, we introduce, in two pairs, four widely used storage metrics that determine the suitability of energy storage systems for grid applications: power & capacity, and round-trip eficiency & cycle life. We then relate this vocabulary to costs. The power of a storage system, P, is the rate at which energy flows through it, in or out.
From systems using electrochemical transformations, to classical battery energy storage elements and so-called flow batteries, to fuel cells and hydrogen storage, this book further investigates storage systems based on physical principles (e.g., gravitational potential forces, air compression, and rotational kinetic energy).
An ideal cycle for an electricity storage system is a sequence where some amount of electricity is used to add energy to the storage system and then exactly the same amount of electricity is produced when energy is extracted from the storage system while it returns to a state that is exactly the same as the initial state.
Specifically, dividing the capacity by the power tells us the duration, d, of filling or emptying: d = E/P. Thus, a system with an energy storage capacity of 1,000 Wh and power of 100 W will empty or fill in 10 hours, while a storage system with the same capacity but a power of 10,000 W will empty or fill in six minutes.
Starting with the essential significance and historical background of ESS, it explores distinct categories of ESS and their wide-ranging uses. Chapters discuss Thermal, Mechanical, Chemical, Electrochemical, and Electrical Energy Storage Systems, along with Hybrid Energy Storage.
