In this project, ENERGY prepares novel sustainable phase change materials (PCM) based on ionic liquids (IL) from natural and renewable sources. These IL-PCMs are tested to the stage of an initial demonstrator and are designed to store and manage heat in smart buildings.

Smart buildings and the energy strategy 2050 have give rise to considerable demand for compact and demand-oriented thermal storage. One solution to meet these requirements is the use of new PCMs with on-demand activation and intelligent control of the heat and cold storage, charge and discharge processes. This means that new PCM must be developed together with a measurement system of their capacity and storage level.
