Abstract
A landmark review of concrete as thermal energy storage material is presented through a bibliometric analysis approach. This study shows influential literature and the current relevant research directions. Geographical source and the identification of the significant publications enable determining the leading authors and research groups of the topic. The methodology is based on an accurately defined query, composed of remarkable keywords for the study. Two queries are set out, the first one from a holistic point of view of the topic, while the second one has a special consideration on concrete as TES under high-temperature conditions. Most part of the literature research pays attention to concrete applications in buildings, while other applications such as solar energy are in the rear face. Throughout the years, great interest in latent heat storage technology is observed using phase change material (PCM), implementing them in concrete mixtures or in other formats integrated into a building component. Despite the fact that the area of research is currently in prominent development, some literature gaps and new research directions are identified. Concepts such as climate change mitigation, concrete components, maintenance, are possible in-progress initiatives which need to be further studied.
Highlights
The planet ecosystems and future fate of mankind are in danger, claiming for an urgent sustainable alternative growth pathway
An energy transition is ur gently required, especially in the building sector, in which energy use accounts for 40% of the worldwide and is responsible for 36% of greenhouse emissions [2]
The objective of this research is, to obtain a chronological overview of concrete and cement-based material when used as thermal energy storage material through a bibliometric approach aiming to provide organized information of the outstanding literature and re searchers on the topic
Summary
The planet ecosystems and future fate of mankind are in danger, claiming for an urgent sustainable alternative growth pathway. Resource scarcity and landfill limits are affecting the environment, responsible for climate change growing-speed. High indoor climate comfort needs are leading to further-up energy consumption. Conse quently, it is becoming a great concern among society. According to the IEA [1], to satisfy space cooling needs, the energy demand today is three time higher than that in the 1990 decade. An energy transition is ur gently required, especially in the building sector, in which energy use accounts for 40% of the worldwide and is responsible for 36% of greenhouse emissions [2]
