Seasonal Solar Energy Storage Technologies in Buildings

In this paper, a review of thermochemical heat storage technologies and systems with solar energy usage in buildings is presented, focusing on thermochemical materials (TCMs) with a charging temperature below 140 degrees C (284 degrees F). The paper is organized as follows: the "Thermochemical Heat Storage" section sums up the fundamentals of thermochemical heat storage and contains an overview of TCMs suitable for solar energy storage. The "Sorption Storage Systems" section presents possible system configurations for thermochemical heat storage and evaluates applications appropriate for reducing the energy needs of buildings. Energy and exergy efficiency of thermochemical storage systems is included in the "Energy and Exergy Efficiency" section, followed by a "Conclusion" section.
