ABSTRACT
The energy produced during industrial processes that are misplaced, wasted, and released into the surroundings is known as industrial waste heat (IWH). Various waste heat recovery systems can retrieve waste heat, generating useful energy sources while lowering overall energy usage. The prospect of waste heat recovery in industrial operations is enormous. IWH is currently underutilized while having great potential. It could result from both the transient or regional mismatch between the energy discharged and its demand, as well as the technical and financial challenges in deploying conventional heat recovery systems. By rescuing the IWH and reserving it for prospective usage, thermal energy storage (TES) is a technique that can address the current mismatch. Additionally, using recovered IWH results in reduced CO2 emissions and financial and energy savings. TES techniques can be installed on-site, or the IWH could be moved using mobile TES (M-TES) strategies to an off-site heat requirement, depending on the space between the IWH reserve and the heat requirement. The present chapter discusses the possible IWH recovery, storage, and utilization routes both on-site and off-site, considering various industrial activities and processes.
