“…The conventional fossil fuels have almost been depleted worldwide, mainly because of the rapid economic development, population boom and rising thermal comfort levels . Latent heat thermal energy storage (LHTES) system using phase change materials (PCMs) is regarded as one of the most promising technique to reduce the dependency on fossil energy sources . During heating‐cooling stages, PCMs undergo a completely reversible switching known as fusion‐solidification cycle, which includes: (1) the melting process, when heat is captured from the surroundings and stored in the material, and (2) the freezing process, when the stored thermal energy is discharged to the atmosphere …”

“…[5][6][7] Latent heat thermal energy storage (LHTES) system using phase change materials (PCMs) is regarded as one of the most promising technique to reduce the dependency on fossil energy sources. [8][9][10] During heating-cooling stages, PCMs undergo a completely reversible switching known as fusionsolidification cycle, which includes: (1) the melting process, when heat is captured from the surroundings and stored in the material, and (2) the freezing process, when the stored thermal energy is discharged to the atmosphere. [11] PCMs could contribute a lot to the thermal energy management, such as leveling off the interior temperature fluctuation, and diminishing costs of the heating, ventilation, and air conditioning system (HVAC), due to its peculiar capability to furnish a high energy storage density at the narrow temperature zone.…”

The effect of nitric acid on the thermal performance of stearic acid/kaolinite (SA/Kaol) composite phase change materials (PCMs) was studied. SA/Kaol was subjected to HNO3 manipulations at different acidity conditions. The results indicated that inferior thermal properties were detected at the acid‐treated composites with pH < 2. The latent heat value of SA/Kaol‐0.5 demonstrated an obvious reduction of about 30% compared with that of SA/Kaol, and its supercooling extent could reach as many as 11.2 °C while that of SA/Kaol was only 1.4 °C. Based on interfacial reaction analysis, the reduced crystallinity of SA should be attributed to the confinement effect originated from acid molecular clusters, while the supercooling behavior was caused by external ions. These ions could hinder SA molecules from adsorbing to the surface of crystal nucleus and thus delay the solidification process. As a result of segregation effect, the latent heat value of acid‐treated samples was deteriorated but the supercooling extent was relieved during thermal cycles. This work was the first that reported the effect of nitrogen oxides on PCMs. We believe that the results could play an enlightening role in the stability study of thermal property during PCMs practical applications.

Summary Energy plays an important role in a fast‐paced modern society. With the depletion of fossil energy, effective utilization of solar energy is getting increasingly urgent. Thermal energy storage is an inevitable choice for effective utilization of renewable energy sources. As one of the most promising renewable energy sources, solar energy is inexhaustible. But it has some shortcomings such as instability and intermittency, affected by time, climate, and geographical location. Thermal energy storage technology, which can effectively reduce the cost of concentrated solar power generation, plays a crucial role in bridging the gap between energy supply and demand. In addition, thermal energy storage subsystem can improve performance and reliability of the whole energy system. According to different principles, thermal storage technology is generally classified as sensible heat storage, latent heat storage, and thermochemical energy storage. Most solar thermal power generation systems, currently demonstrated and operated in the world, adopt the method of sensible thermal energy storage. In contrast, thermochemical energy storage is a relatively new concept, which is still in the stage of basic test and verification. Thermochemical energy storage technology stores and releases energy through endothermic and exothermic reversible reactions. A closed system with separated reactants and products, in theory, can store energy indefinitely. The main thermochemical energy storage systems include redox system, metal hydride system, carbonate decomposition system, ammonia decomposition system, methane reforming system, and inorganic hydroxide system.

Higher shares of fluctuating generation from renewable energy sources (RES) in the power system lead to an increase of grid balancing demand. One approach for avoiding RES curtailment, is to use excess electricity feed-in for heating applications. To assess in which regions power-to-heat (PtH) technologies can contribute to RES integration, detailed data on the spatial distribution of the heat demand are needed. In this contribution, we determine the overall heat load in the residential building sector and the share covered by electric heating technologies for each administrative district (NUTS-3) in Germany, with a temporal resolution of 15 minutes. For the detailed regionalisation of the residential building stock, we ordered a special evaluation of the German census data at the Research Data Centre with a combination of six building features. Using these data, 729 building categories were defined and heat demand values were assigned to each category. Furthermore, heating types and different classes of installed heating capacity were defined. Our analysis showed that the share of small scale single-storey heatings and large scale central heatings is higher in cities, whereas there are more medium scale central heatings in rural areas. Both is caused by the different shares of single and multi-family houses in the respective regions. To determine the electrically covered heat demand, we took into account heat pumps and resistive heating technologies. All results, as well as the developed code are published along with this contribution under open source licenses and can thus also be used by other researchers for the assessment of power-to-heat for RES integration.
