Mechanical Storage

These requirements cover energy storage systems that are intended to receive and store energy in some form so that the energy storage system can provide electrical energy to loads or to the local/area electric power system (EPS) when needed. The types of energy storage covered under this standard include electrochemical, chemical, mechanical and thermal. The energy storage system shall be constructed either as one unitary complete piece of equipment or as matched assemblies, that when connected, form the system. This standard is a system standard, where an energy storage system consists of the an energy storage mechanism, power conversion equipment and balance of plant equipment as shown in Figure 6.1. Individual parts (e.g. power conversion system, battery system, etc.) of an energy storage system are not considered an energy storage system on their own. This standard evaluates the compatibility and safety of these various components integrated into a system.

With the increase of new technologies of energy storage there is need for a global overview of an energy storage system for use in stationary information and communication technology (ICT) installation in network, data centre and customer premises equipment (CPE), and simple evaluation of acceptable duration and characterization methods for this specific purpose. This Recommendation introduces an open series of documents for different families of technologies (battery systems, super-capacitor systems, etc.) that will be enriched progressively as new technologies emerge that may have a possible significant impact in the field of energy storage. Identified parts of the Recommendation series innovative energy storage technology for stationary use are: - Part 1: Overview of energy storage - Part 2: Battery - Part 3: Super-capacitor technology

This Code applies to mechanical or thermal ESS including, but not limited to, compressed air, flywheel, molten salt, and pumped hydromechanical ESS and sensible, latent, cyrogenic, thermochemical, ice-based, or phase-change-material thermal ESS. ASME PTC 53 applies to the measurement of the performance of an ESS at the specified conditions, with all equipment associated with the system functioning in accordance with those conditions.
