The R&D project FlexModul is developing an innovative, modular and compact sorption storage system. The so-called thermochemical storage is characterized by high energy storage density and flexibility. Furthermore, it has low losses and is easy and safe to use. The investment costs can also be reduced to a minimum, which maximizes the applicability of the concept.
The modular design of the sorption storage allows it to be scaled and adapted to various applications in the heat and power sector. Due to the different areas of application, the enormous potential of thermal storage as cross-sectional technologies becomes visible. This increases the flexibility of the entire energy system, reduces CO2 emissions and allows long-term storage with almost no loss.
The project is also about demonstrating the diverse possible uses of sorption storage using two use cases. The first use case is the seasonal storage of solar energy for a single family home. The second use case demonstrates power-to-heat (P2H) storage in the hospitality industry.
