“…Nkwetta and Haghighat did a review on available technologies including active systems for thermal energy storage with PCMs [9]. Sharif et al likewise did a review on applications with PCMs for space heating and domestic hot water preparation [10]. None of these reviews included technologies that utilize supercooling of a PCM.…”

h i g h l i g h t sThermal energy storage units with supercooled of sodium acetate trihydrate are characterized. Heat exchange capacity rates were lower for units with PCM with thickening agents. Phase separation of sodium acetate trihydrate was avoided by thickening agent. a b s t r a c t Latent heat storage units utilizing stable supercooling of sodium acetate trihydrate (SAT) composites were tested in a laboratory. The stainless steel units were 1.5 m high cylinders with internal heat exchangers of tubes with fins. One unit was tested with 116 kg SAT with 6% extra water. Another unit was tested with 116.3 kg SAT with 0.5% Xanthan rubber as a thickening agent and 4.4% graphite powder. The heat exchange capacity rate during charge was significantly lower for the unit with SAT and Xanthan rubber compared to the unit with SAT and extra water. This was due to less convection in the thickened phase change material after melting. The heat content in the fully charged state and the heat released after solidification of the supercooled SAT mixtures at ambient temperature was higher for the unit with the thickened SAT mixture. The heat discharged after solidification of the supercooled SAT with extra water decreased over repeating charge and discharge cycles while the heat discharged from the SAT with Xanthan rubber remained stable. In both units, the solidification started spontaneously in the majority of the test cycles. This was due to the design of the unit or the method for handling the expansion and contraction of the SAT during charge and discharge.

“…The storage tank is an important part of the solar water heating system, generally constructed using steel, concrete, plastic, fiber glass or other materials (Shukla et al, 2013). Phasechanging materials can reduce the thermal energy loss in either pipe or duct networks and the initial cost because they do not need insulation and storage tanks and thus save space (Sharif et al, 2015).…”

The high cost and environmental impact of fossil-fuel energy generation in remote regions can make renewable energy applications more competitive than business-as-usual scenarios. Furthermore, energy and transport are two of the main sectors that significantly contribute to global greenhouse gas emissions. This paper focuses on the generation of thermal energy and the transport sector of a fossil fuel-based energy independent island in Greece. We evaluate (1) technologies for fully renewable thermal energy generation using building-specific solar thermal systems and (2) the replacement of the vehicle fleet of the island with electric and hydrogen-fueled vehicles. The analysis, based on economic and environmental criteria, shows that although solar thermal decreases greenhouse gases by 83%, when compared to the current diesel-based situation, it only becomes economically attractive with subsidy scenarios equal to or higher than 50%. However, in the transport sector, the sum of fuel and maintenance costs of fuel-cell and electric vehicles is found to be 45% lower than that of the current fleet, due to their approximately seven times lower fuel cost. Lastly, it will take approximately six years of use of the new vehicles to balance out the emissions of their manufacturing phase.

“…Various researchers have also explored the possibility of using phase change materials (PCMs) as heat storage media since they have much higher energy storage capacity and energy storage density than water [2,[10][11][12][13]. For instance, Murray and Groulx [10] evaluated a PCM based TES system and achieved about 44.3% increase in energy storage density as compared with water based system.…”

In this paper a novel microencapsulated phase change material (MF-3) has been developed and tested for solar assisted hot water storage systems. Even though the morphology of the sample was affected by the type of emulsifier used for fabrication it recorded the highest energy storage capacity of 126 kJ/kg with encapsulation efficiency of 97.4% as compared with other developed samples. For the purpose of assessing its thermal effectiveness it was theoretically evaluated in a compacted fixed bed TES unit and found to be capable of achieving a higher energy storage density as well as relatively smaller physical storage size than water based system. Despite the overall effective thermal conductivity being slightly less than water, its value was still about twice as high as most current PCM storage units. Experimental evaluation is therefore strongly encouraged.
