ENERGY STORAGE

Written and edited by a team of well-known and respected experts in the field, this new volume on energy storage presents the state-of-the-art developments and challenges in the field of renewable energy systems for sustainability and scalability for engineers, researchers, academicians, industry professionals, consultants, and designers.

The world's energy landscape is very complex. Fossil fuels, especially because of hydraulic fracturing, are still a mainstay of global energy production, but renewable energy sources, such as wind, solar, and others, are increasing in importance for global energy sustainability. Experts and non-experts agree that the next game-changer in this area will be energy storage.

Energy storage is crucial for continuous operation of power plants and can supplement basic power generation sources over a stand-alone system. It can enhance capacity and leads to greater security, including continuous electricity supply and other applications. A dependable energy storage system not only guarantees that the grid will not go down, but also increases efficacy and efficiency of any energy system.

This groundbreaking new volume in this forward-thinking series addresses all of these issues, laying out the latest advances and addressing the most serious current concerns in energy storage. Whether for the veteran engineer or the student, this latest volume in the series, "Advances in Renewable Energy, " is a must-have for any library.

This outstanding new volume:

• Is practically oriented and provides new concepts and designs for energy storage systems, offering greater benefit to the researcher, student, and engineer
• Offers a comprehensive coverage of energy storage system design, which is also useful for engineers and other professionals who are working in the field of solar energy, biomass, polygeneration, cooling, and process heat
• Filled with workable examples and designs that are helpful for practical applications, also offers a thorough, novel case study on hybrid energy systems with storage
• Is useful as a textbook for researchers, students, and faculty for understanding new ideas in this rapidly emerging field

Abstract

This chapter presents the relevance and integration of TES for CSP technologies. A TES system consists of the storage material, heat transfer equipment, and storage tank. The TES material stores the thermal energy either in the form of sensible heat, latent heat and thermochemical energy via chemical reactions. There are several requirements that must be considered to ensure optimal storage dynamics and longevity in a TES. These requirements are analysed and discussed. A broad spectrum of storage technologies, materials and methods are explored for the selection of suitable TES for CSP technologies. Materials for heat transfer fluid and material for energy storage that are generally used in TES are presented. Various limitations and problems of TES systems, such as high temperature corrosion with their proposed solutions, as well as successful implementations are reported. Further, storage media and storage type selection for CSPs based on their stability, material characterization and compatibility of materials are explained. Various available CSP technologies such as parabolic trough collector technology, linear Fresnel collector technology, solar tower technology, Stirling dish technology, etc., are discussed in detail and compared. Factors to be considered at different hierarchical levels for each CSP technologies with TES are explained.

Keywords: Solar thermal, thermal energy storage, parabolic trough collector, solar tower, stirling dish technology

1.1 Introduction

According to the International Energy Agency (IEA) in 2019, global energy demand will rise by 1.3% each year to 2040. Non-renewable energy takes up a major percentage of the global energy sector. The awareness and use of renewable energy is one of the ways to meet sustainable energy goals and to alleviate the associated environmental problems including carbon emission. Also, the development on renewable energy is significantly slow-paced as observed in the last few decades. The development of renewable energy is seen only in very few countries. The most popular renewable energy sources currently under consideration are wind energy, solar energy, tidal energy, geothermal energy, hydro energy, etc. Due to many benefits including ready availability, the larger proportion of interest is taken by solar energy among various types of renewable energy sources (Regin et al., 2008). However, the momentum of renewable energy technologies is not as significant as is needed with the expansion of the global economy and growth of population.

In the solar energy field, two major breakthrough technologies that have attracted significant attention in many countries are Solar Photovoltaic (PV) power generation and Concentrated Solar Power (CSP) plants. In solar PV plants, the solar energy is directly converted to electricity by using solar cells (Muhammad and Arshad, 2020; Jain et al., 2020; Khajepour and Ameri, 2020; Ahmed et al., 2020; Zhang et al., 2013). The solar energy to electrical energy conversion efficiency of a commercial grade PV is observed to be less than that of CSP systems and power dispatch is not possible in PV-based solar power production. Other than larger energy efficiency, one of the major advantages of CSP is its ability to provide electrical power at nighttime and during cloudy hours. This can be made possible by incorporating Thermal Energy Storage (TES) system. The capacity to dispatch power is more in a CSP system than that of a PV-based solar power sy...
