Opis

This book provides a descriptive classification of the various concepts, giving characteristic performance data and design fundamentals. Systems based on sensible heat storage, latent heat storage and thermo-chemical processes are presented, including the state of maturity and innovative solutions. Essential for the effective integration of thermal storage systems is the optimal adaption to the specific requirements of an application. This is shown in the second part, where storage solutions for conventional and solar thermal power plants are described. Further examples show the integration into batch processes, mobile applications or options to support the utilization of waste heat. Systems using thermal energy storage for facility scale storage of electricity are also described.
Storage systems for medium and high temperatures are an emerging option to improve the energy efficiency of power plants and industrial facilities. Reflecting the wide area of applications in the temperature range from 100 C to 1200 C, a large number of storage concepts has been developed.

Energy storage is considered an essential component for ensuring security of supply in future energy systems with increasing shares of renewable energies. Since thermal energy accounts for a significant portion of the total demand, the use of thermal storage systems is an obvious choice. This book focuses on systems operating between 100–1200 °C and is intended as a resource to provide the necessary information for understanding, selecting, developing, operating, and managing these storage systems.

In the first part an overview of state of the art and innovative storage concepts is given, describing their characteristics and providing the fundamentals required for the design of these storage systems. Various areas of application for thermal storage systems are described in the second part of this book, demonstrating the selection of a storage concept and its adaptation to the specific boundary conditions. One example for these applications areas are commercial solar thermal power plants, where the cumulative integrated storage capacity allows the off-sun generation of electricity in the multi-GWh range. The book also includes emerging application areas like the facility scale storage of electric energy or industrial application where thermal storage can improve the energy efficiency of batch processes or allows the demand-side management of renewable energy.
