Design of Thermal Energy Storage / Buffer Tank. 1. Introduction. Thermal Energy Storage (TES) systems store thermal energy for use at a later time when it is more cost-effective or necessary to generate energy. With TES tanks, the operating cost and required capacity of the cooling and heating plants are reduced.

A simple ordinary differential equation was used to model the TES state of charge, depending on the primary chilled water flow from the chillers (m ˙ c h) and the chilled water flow needed by the secondary loop (m ˙ l o a d).(4) S O C ˙ = m ˙ c h − m ˙ l o a d where SOC is the state of charge and m ˙ c h, m ˙ l o a d are the primary and secondary

Compressed Air Energy Storage (CAES) at large scales, with effective management of heat, is recognised to have potential to provide affordable grid-scale energy storage. Where suitable geologies are unavailable, compressed air could be stored in pressurised steel tanks above ground, but this would incur significant storage costs.

A solar thermal storage tank is an essential part of a solar thermal system, which harnesses the sun''s energy to produce heat.
