Project description
The Lämpöakku (Heat Battery) project aims at developing energy efficient, profitable, modular, scalable, and sustainable energy storage technology based on heating of inorganic materials from secondary sources. In the Heat Battery concept, the excess electricity generated by VRES can be stored as high temperature thermal energy (>500°C), to be used later for heating of solids and gases as well as for production of steam in industrial applications on-demand. Additionally, the thermal energy can be used as heat source for district heating or for heating of houses and commercial greenhouses, as well.
The Heat Battery concept generates options for creating new businesses and jobs related to the construction and operation of heat batteries as well as for the generation of thermal energy for the customers. Additionally, the heat battery enables the energy sector to capture excess VRES generation, which will also help reducing electricity price volatility. As the Heat Battery is based on industrial side stream materials, this concept will also enhance the integration of the energy industry and the circular economy.
In this joint project of University of Oulu and Oulu University of Applied Sciences, the characteristics and thermal properties of industrial side products will be studied in detail. The operation of the Heat Battery will be modelled at different levels, i.e., at the level of a piece of material, at the battery level and at the systemic level of the energy production network.
