“…Within the FlowTCS project [51], an open adsorption storage system with an external reactor configuration has been developed, whereby zeolite and salt-impregnated zeolite were used as the sorbent. The storage system consists of a reactor with approximately 30 L of zeolite and the adsorbent storage reservoir with a volume of 200 L, thereby achieving a high flexibility regarding both storage capacity and heat output.…”

Thermochemical heat storage is a very promising technology that enables us to save the excess heat produced during summer time for the needs in the winter, when we have higher heating needs. Thermochemical heat storage bases and an overview of thermochemical materials (TCMs), suitable for the solar energy storage, are given. Choosing a suitable adsorbent and adsorbate is very important. The most important properties of the substance are high energy density for high thermal storage, low charging temperature for low energy consumption, high uptake of sorbate kg(sorbate)/kg(sorbent) and environmental safety and easy to handle-nonpoisonous. The paper also presents the differences between the closed and the open sorption system. The biggest difference between those two systems is the importance of sorbent, which in case of open systems means that sorbent must be environmentally friendly. Also, various closed and open systems are presented.

Phase Change Materials (PCM) for Solar Energy Usages and Storage: An Overview

Solar energy is a renewable energy source that can be utilized for different applications in today’s world. The effective use of solar energy requires a storage medium that can facilitate the storage of excess energy, and then supply this stored energy when it is needed. An effective method of storing thermal energy from solar is through the use of phase change materials (PCMs). PCMs are isothermal in nature, and thus offer higher density energy storage and the ability to operate in a variable range of temperature conditions. This article provides a comprehensive review of the application of PCMs for solar energy use and storage such as for solar power generation, water heating systems, solar cookers, and solar dryers. This paper will benefit the researcher in conducting further research on solar power generation, water heating system, solar cookers, and solar dryers using PCMs for commercial development.

“…It is applied on a time scale from hours and days up to several months, in the latter case referred to as long-term or seasonal thermal energy storage [1,2]. This is an important asset for renewable heating of buildings [3][4][5][6][7]. Research activities in the field of long-term thermal energy storage have increased and a broad range of system designs employing different storage materials has been evaluated and tested.…”

In sorption heat storage, one of the sources of discrepancy between theoretical material based energy storage potential and resulting system performance is the choice of process type. In this paper, in order to understand this performance deviation, a sorption heat storage process categorisation is proposed. This is followed by a review of reported sorption systems categorised according to the proposed process classification. An analysis of the reported systems is then undertaken focusing on the ratio of resulting temperature gain in sorption (ad-or absorption) compared to required temperature lift in desorption. This measure is termed temperature effectiveness and enables a form of system performance evaluation in the broad landscape of sorption thermal energy storage demonstrators. It is argued that other performance parameters such as volumetric energy storage density and volumetric charge and discharge power density are not adequate for comparison due to the highly varying testing conditions applied. From the system evaluation, it is seen that best temperature effectiveness is generally found in a closed, transported process with the ability of single sorbent pass and true counter flow heat exchange. Highlights • There are four basic sorption thermal energy storage processes, open fixed, open transported, closed fixed and closed transported.• Temperature effectiveness, the ratio of resulting sorption temperature lift to required desorption temperature lift, is a universal means for sorption heat storage system performance comparison.• Closed transported sorption thermal energy storage systems show the best performance in respect to temperature effectiveness.
