Rural electrification is bound by high capital costs, low dependability, and unworkable business models, whereas decentralised renewable energy power is constrained by high capital costs, low reliability, and unworkable business models. Solar thermal energy may generate electricity, heat, cool, water, and fuel, and it has the ability to be stored for future use.

By using pressureless sintering, ceramic anorthite solar thermal energy storage materials were created from solid magnesium slag waste. On the physical, chemical, and thermophysical properties of ceramics, the impacts of the CaO/SiO2 ratio and the sintering temperature were investigated. The creation of anorthite was shown by X-ray diffraction data to be a result of the thermal shock process, and the conversion of anorthite (CAS2) into melilite was facilitated by an increase in the CaO/SiO2 ratio (C2AS).

In this study, a hybrid heating system made up of a ground source heat pump (GSHP) and a loop heat pipe solar collector (LHPSC) is proposed to regulate greenhouse temperature in Harbin, the coldest provincial capital in China. For the purpose of predicting transient greenhouse temperature corresponding to the energy supplied by GSHP, a combined thermal resistance network and energy balance model is created.

In order to create ideal weather conditions for growing plants during cold weather, greenhouse heating is necessary. The performance of an Active Solar Heating System (ASHS) made up of two solar water heaters outfitted with flat solar collectors, two storage tanks, and exchanger pipes has been examined in this paper.
