Energy storage system is a system built to store high grade or low grade energy of a system, which can be
utilized in near future. Energy storage becomes a key element in achieving goals in energy sustainability that lead to
energy and cost savings. A device that stores energy is sometimes called an accumulator.
This Accumulator can be used to store waste heat energy, of waste water of a system, by a process called Waste Water
Energy Recovery (WWER). Waste heat is the unused heat (secondary/low-grade heat) of a system, which is given to
the surrounding (in the form of thermal energy) by a heat engine in a thermodynamic process. This heat can be
useful in the majority of heating applications; however, difficulty is faced for storage and transportation of waste
heat. Power stations, Industries, and electronics market are the major sources of waste heat.
The Heat Accumulator or Thermal energy storage (TES) system to be used is a Double tube Heat Exchanger with
Phase Change Material (PCM) as one of its crucial components. PCM is a ‘latent’ heat storage material which works
on its solid-liquid phase cycle.
