There are lots of types of TES, which can be divided by the heat storage material (e.g., steel, concrete, water), by the physical behavior of the heat storage material (sensible, latent) or by other criteria. Due to the variety of TES, there is a fitting solution for almost every customer’s process. But it is essential to consider all operational states (charging, storing, discharging) to match the TES with the energy source and the consumer.
Besides the TES itself, one also must take care of the heat transfer between the heat source, the storage material, and the consumer. This is done by the Balance of Plant (BoP), which especially includes the necessary heat exchangers, pumps, control devices and other components.
A typical use case of a TES can be found in hydraulic press applications, which usually have a cyclic load profile with heating and cooling phases. For these applications, we realized systems with a direct hot oil buffer storage, which is charged during cooling phase and can be discharged for heating. Another option would be a two-tank solution, storing hot and cold oil in different vessels whereas one of the vessels can be empty. For CST systems, we were involved in projects with different approaches, such as a solid-state TES for a thermal oil system up to 400 °C or a liquid-state TES for a pressurized water system with a design temperature of 240 °C.
