A global transition towards more sustainable production and consumption systems has led to an increasing share of renewables in the energy market. Renewables, majorly solar PV and wind power are accounted for around 10 % of the global power production in 2020. In this context, concentrated solar power (CSP) technologies are seen to be one of the most promising ways to generate electric power in coming decades. However, because of the intermittent nature of solar energy, one of the key factors that determine the development of CSP technology is the integration of efficient and cost-effective thermal energy storage (TES) systems. TES system not only plays a crucial role in bridging the gap between energy supply and demand but also increases the performance and reliability of energy systems and plays a crucial role in energy conservation. Though there have been many reviews on TES system, however the existing literature is either over 5 years old or focus on thermal storage materials for low temperature applications. To bridge this gap, this work presents a comprehensive review on the actual state of all major components of cutting-edge TES technologies for CSP application and condenses all the available information and categorizes them considering the main functional parts and remarking the current research progress in each part as well as the future challenging issues. It intends to understand and explain the foundations of the innovative concepts, future research directions and strategies developed over the past 10 years to tune the engineering and thermal sciences of TES systems. Insight into classes of TES storage materials with details on geometrical configurations, design parameters, physical properties, operational issues, cost, technology readiness level, suitability to CSP application and comparative assessment of various TES systems is provided.
