The main challenge into accelerate the sustainable development of power and thermal energy technologies is to optimize and reduce global warming impact while increasing efficiency and dispatchability of generated energy. Hence the role of storage systems as a link between production and optimal load distribution is becoming more and more prominent.

Therefore, the role of suitable cementitious materials as the binder in the manufacture of concrete for thermal energy storage (TES), both in terms of feasibility and lowering the environmental impact to substitute commonly used ordinary Portland cement (OPC) materials for use in concentrated solar power (CSP) plants are inevitable.

So, current research focuses on the development of appropriate OPC concrete mixing to increase thermal performance and durability of cements at high temperature ranges. Therefore, there is a possibility to integrate it with related applications such as power generation, industrial energy recovery and thermal plants, also other concept of storage such as active scheme can be further examined after real condition tests. So, the future steps in this research are to convert the laboratory and numerical obtained values to a more practical scale and to study the viability under real operation scenarios, also heat- exchanger design and cost analysis will be included for scalability evaluation.
