Piotr Piechota, PhD, from the Division of Energy Metering Team of the Department of Thermal Sciences, involved in the development of the Ice Battery System - an energy accumulation installation based on ice batteries. The whole system is based on the use of ice cores. To store the energy required for cooling, it is sufficient to freeze the cores using glycol. The freezing process requires electricity, which can be collected, for example, from photovoltaic installations or from the grid when the tariff is lower. The process of charging ice cores in the Ice Battery system is carried out during energy surplus. As soon the ice melts, the stored energy can be collected and used for cooling.  

Another advantage of the system is its modular design, which allows for expansion with additional Ice Battery units. However, the increase in power must be tailored to the specific application.
- The idea is to match the system's power to the company's production cycle in order to keep the entire process running. Among other things, the team from the Wrocław University of Science and Technology carried out the metering of the system, as well as acted as consultants in metrological issues and prepared its energy balance, explains Piotr Piechota, PhD, from the Department of Thermal Sciences.
