Reducing thermal energy use in industry is an effective way to improve energy efficiency. Process integration methods tackle this challenge, of which pinch analysis is a popular approach for identifying direct heat recovery measures. Many processes are batch processes that can profit from indirect heat recovery using thermal energy storage (TES). This paper presents a systematic conceptual TES integration methodology. In addition, functionality to support this methodology has been implemented in the PinCH software and is presented in a case study.
