To solve the issues of flowing and leaking of myristic acid (MA) as phase change energy storage material in practical application, a novel microencapsulated composite phase change energy storage material was prepared by sol-gel method using myristic acid (MA) as core material and titanium dioxide (TiO2) as shell material. The chemical structure, crystal structure, micromorphology, phase change characteristics and thermal stability of phase change microencapsulated energy storage materials were characterized by using Fourier transform infrared spectrometer (FT-IR), X-ray diffraction analyzer (XRD), field emission scanning electron microscope (FE-SEM), differential scanning calorimetry (DSC), thermogravimetric analyzer (TGA). The consequents illustrated that the ideal sample melted at 54.97 °C with the latent heat of 55.76 J/g and solidified at 49.85 °C with the latent heat of 54.55 J/g. In general, the prepared microencapsulated phase change materials possessed good thermal properties and thermal stabilities. It is predicted that the shape-stabilized MA/TiO2 composites have great potential for thermal energy storage.

Organophilic Bentonite / Paraffin composite phase change energy storage materials (OB/P PCM composite) were prepared by melting intercalation method. Under high temperature, no melt paraffin seep out from the PCM of organophilic bentonite/paraffin (OB/P) mass ratio is 2:1, which paraffin content is largest. Samples were tested by X ray diffraction (XRD), Scanning Electron Microscope (SEM), Differential scanning calorimetry (DSC) and Fourier Transform Infrared Spectroscopy (FTIR). Paraffin was well intercalated into layerd bentonite. Melting point and fussion heat of composite PCM with mass ratio2:1 are 45.7 °C and 68.7 kJ/kg, it can be added to solar energy.

Adsorption Quantity

Paraffin/expanded perlite composite phase change energy-storage material (PPCM) was prepared by vacuum adsorption method with expanded perlite as adsorption material and paraffin as phase change energy-storage material. The diffused-exudative circle method was used to determine that the best adsorption quantity of expanded perlite was 65%. The phase transition process and microstructure of PPCM with the best adsorption quantity were characterized by DSC and SEM. The results shown that the internal micropores of expanded perlite particles were almost completely filled with paraffin and the expanded perlite particles became close-grained particles. The phase change temperature of PPCM was basically similar with that of paraffin and its phase change latent heat was corresponded with that of paraffin in the PPCM.

Desalination of seawater and brackish water is an issue of concern of many researchers in today’s scenario. Solar energy is realizable, simple, profitable choice for water distillation. The present experimental study shows the effect of different operating parameters (water depth, solar radiation, energy storage materials) on a single slope plane solar still. An improvement of distillate output of solar still has been recorded using energy storage material. A comparison between the modified still and conventional still was carried out under the same climate conditions with 5 cm depth of water. The effect of sensible heat storage material have been investigated. The average distilled water production achieved was 2065 ml/m2/day.

Storage Materials

Renewable energy has the ultimate capacity to resolve the environmental and scarcity challenges of the world’s energy supplies. However, both the utility of these sources and the economics of their implementation are strongly limited by their intermittent nature; inexpensive means of energy storage therefore needs to be part of the design. Distributed thermal energy storage is surprisingly underdeveloped in this context, in part due to the lack of advanced storage materials. Here, we describe a novel family of thermal energy storage materials based on pyrazolium cation, that operate in the 100-220°C temperature range, offering safe, inexpensive capacity, opening new pathways for high efficiency collection and storage of both solar-thermal energy, as well as excess wind power. We probe the molecular origins of the high thermal energy storage capacity of these ionic materials and demonstrate extended cycling that provides a basis for further scale up and development.
