Energy Storage

Background
Advancement in technology and an increasing demand for more reliable energy systems has created growth in the energy storage industry. As weather continues to change and become more extreme, it has become increasingly vital to have energy infrastructure systems that can withstand and resist such natural disasters.

While solar energy may be the leading renewable energy source, storage challenges have limited its adoption by utilities. Thanks to innovations in thermal energy storage in MWh quantities, solar thermal energy has become more feasible for large-scale applications.

Thermal energy can be stored in sensible, latent, or chemical form. The storage of industrial quantities of thermal energy is in a nascent stage and primarily consists of sensible heat storage in nitrate salt eutectics and mixtures.

Current status
ASME formed the Thermal Energy Storage (TES) Standards Committee which will oversee development of  design, construction, testing, maintenance, and operation requirements of thermal energy storage systems for the life cycle of the equipment

The committee has completed the draft for TES-1, Safety Standards for Thermal Energy Storage Systems: Molten Salt. The first edition of TES-1 is expected to be published in late 2020. The Committee is now actively seeking participants with expertise in phase change thermal energy storage systems to begin work on a draft for TES-2, Safety Standard for Thermal Energy Storage Systems: Phase Change.

ASME formed the Performance Test Codes (PTC) 53 Mechanical and Thermal Energy Storage Systems Committee which oversees the development of uniform test methods, procedures, and quantifiable methods for assessing, determining, and reporting the performance of mechanical or thermal energy storage systems across varying technology platforms. This applies to systems including, but not limited to, compressed air, fly wheels, molten salts, or pumped hydro for storing energy mechanically or thermally from any source.

The committee published the PTC 53 Mechanical and Thermal Energy Storage Systems Draft Standard for Trial Use. Following the trial use period, the committee finalized the PTC 53 document and it is expected for publication in early 2021.

Meetings and Events
Thermal Energy Storage Standards Committee - meets every 2-3 months via teleconference.
PTC 53 Mechanical and Thermal Energy Storage Systems Committee - meets by teleconference quarterly and holds 1-2 in-person meetings throughout the year.
