Project description The aim of this project is to develop an open, air-based liquid sorption storage system which can be regenerated using waste process heat or solar thermal energy. The prototypes developed will consist of a regenerator, absorber and liquid sorption tank, be usable for a variety of cooling, heating and drying applications and facilitate the hourly, daily or weekly storage of thermal operating energy (depending on the area of application). Efficient energy storage is especially dependent on the sorption and desorption of the medium in the liquid sorption tank, which is therefore the main area of research focus. The results of analysis of the use of liquid sorption storage systems for cooling, heating and drying applications carried out during Phase 1 will feed into the development of various system concepts for sorption/desorption modules during Phase 4. Laboratory research into potential sorbents during Phase 2 and analysis of storage density and process management during Phase 3 will provide a foundation for the development and design of absorption and regeneration/storage modules during phases 5 and 6. Assessment of the performance of both individual modules and the collector module as a whole will be followed by the development of complete liquid sorption storage systems – as well as sorption/desorption strategies for selected areas of application – during Phase 7. This will be supplemented by cost-benefit analysis and commercial assessment of the overall system during Phase 8.
