“…The characterisation analysis conducted by Jarimi et al (2017) demonstrated the feasibility of using the vermiculite-based composite adsorbents in THS systems. The THS system is still under the research and development stage, which requires more studies on the innovative composite adsorbents and reactor designs (Shen et al, 2021).…”

Industrial processes and the building sector (e.g., for space and water heating) are responsible for the majority of the total energy consumed for heat. Although fossil fuels remain to dominate the heating sector, renewable heating technologies have been lately widely deployed. Thermochemical energy storage (TES) can be a promising advanced technology in addressing the mismatch between renewable energy supplies and the end-user's demand. In this paper, a novel Vermiculite-based Solar Thermochemical Heat Storage (VS-THS) system was proposed for domestic space heating applications, which could also overcome the intermittency challenges and realise long-term solar energy storage. A small-scale prototype was set up to evaluate the energy storage performance of the proposed system using a patented ChainStore panel to accommodate vermiculite-based composite. The unique design of the ChainStore arrangement offers great heat and mass transfer and good flexibility for system resizing in the case of varying the building energy demand. Due to the low regeneration temperature (63 °C) and high energy storage density (253.8 kWh/m 3 ) of the vermiculite-based adsorbent impregnated with MgSO 4 and CaCl 2 , it was chosen as the THS composite in the experiments. The experimental results showed that the proposed VS-THS is feasible for domestic space heating, with the highest space heating supply temperature of 37.6 °C, and the system COP in the reaction process is 7.9-10.4. In addition, the results also demonstrate that the composite of vermiculite impregnated with MgSO 4 and CaCl 2 , with a good water adsorption performance. This proposed concept of VS-THS could be sized for different building applications.

“…As one of the prominent renewable energy, solar energy has been widely used for domestic water or space heating around the globe due to its various merits of cleanliness, abundance, effectiveness, etc. , It was reported that two thirds of the land areas of china have direct normal irradiance levels exceeding 1095 kW·h/m 2 /year (3 kW·h/m 2 /day). Solar radiation resources are quite abundant in the cold regions in the west of China and Inner Mongolia .…”

A novel solar energy storage heating radiator (SESHR) prototype filled with low-temperature phase change material (PCM) has been developed to accommodate the urgent demand in thermal storage and the fluctuation in renewable energy utilization. This equipment integrated by several independent heat storage units (HSUs) and water and paraffin wax was used as a heat transfer fluid and an energy storage material, respectively. The experimental test platform for low-temperature SESHR was designed and established. The total storage/dissipation time, average storage/dissipation capacity, and the rate and overall thermal efficiency were investigated under different operating conditions. Experimental results showed that a higher temperature difference between the heat source and the melting point of the PCM could significantly improve the heat storage capacity and rate. The heat dissipation rate of the SESHR could be controlled by adjusting the opening ratio of the air convective channel. The average storage rate of the SESHR with 2#PCM reached 1106 W at a heat source temperature of 85 °C, and the average heat dissipation rate reached 80.7 W at 100% opening ratio when the SESHR was filled with 1#PCM.

This study consists of a sensitivity analysis of photovoltaic/thermal (PV/T) collectors, liquid thermal storage, and battery systems applied for the offices of a school building near Montreal, Canada to enhance building performance and resiliency to power outages during winter operation. The analysis was applied for 3 days in January with mixed solar conditions by varying the sizing of each of the components to achieve at least 8 h of self-sufficiency, the average length of power outages. It was found the optimal sizing for the studied system, while minimizing component costs, is to dimensions PV/T collectors to meet the base heating load, while maximizing thermal storage, and diminishing battery capacity to meet the base heat pump electricity consumption. For the case study, the optimal configuration was 27 PV/T, a 908 L thermal storage tank, and 10 kWh of battery capacity, to consistently achieve over 8 h of self-sufficiency in mixed sunny and cloudy winter conditions.
