“…The process begins with the calcination of CaCO 3 in a reactor using concentrated solar energy as the source of heat. As the heat source for thermochemical reactions and storage, industrial waste heat can also be used as input . In order to carry out the endothermic reaction to form CO 2 and CaO products, energy from the concentrated plants or industrial waste heat was supplied.…”

Summary Because of the unstable and intermittent nature of solar energy availability, a thermal energy storage system is required to integrate with the collectors to store thermal energy and retrieve it whenever it is required. Thermal energy storage not only eliminates the discrepancy between energy supply and demand but also increases the performance and reliability of energy systems and plays a crucial role in energy conservation. Under this paper, different thermal energy storage methods, heat transfer enhancement techniques, storage materials, heat transfer fluids, and geometrical configurations are discussed. A comparative assessment of various thermal energy storage methods is also presented. Sensible heat storage involves storing thermal energy within the storage medium by increasing temperature without undergoing any phase transformation, whereas latent heat storage involves storing thermal energy within the material during the transition phase. Combined thermal energy storage is the novel approach to store thermal energy by combining both sensible and latent storage. Based on the literature review, it was found that most of the researchers carried out their work on sensible and latent storage systems with the different storage media and heat transfer fluids. Limited work on a combined sensible‐latent heat thermal energy storage system with different storage materials and heat transfer fluids was carried out so far. Further, combined sensible and latent heat storage systems are reported to have a promising approach, as it reduces the cost and increases the energy storage with a stabilized outflow of temperature from the system. The studies discussed and presented in this paper may be helpful to carry out further research in this area.

Japan is faced with sustainability challenges such as resource security and depopulation. Well-coordinated, multifaceted actions including a shift from imported fossil to locally available renewable resources and empowering of rural areas are vital in tackling these challenges. Here, we present our co-learning approach to practice the multifaceted actions with a case study on Tanegashima, an isolated Japanese island. In these actions, thorough understanding of the feasible technologies, the locally available resources, and the socioeconomic aspects of the local community should be shared among the stakeholders to acquire the momentum for a change. In addition to the technoeconomic analysis, several other analyses were conducted to reveal the concerns of respective stakeholders, share the understandings on the possibilities of technology options, and their socioeconomic implications on local sustainability. Tools such as the life cycle assessment, input-output analysis, and choice experiments based on questionnaire surveys on the residents' preferences are used for the analyses. The stakeholders were provided with the results during a 5-year period, through more than 30 co-learning events, e.g., symposiums, seminars, and workshops. A total of ca. 1400 participants from residents, local industries, public organizations, and a high school joined these events. These opportunities gradually converted the concerns of the local stakeholders on their future regional energy systems into expectations and yielded constructive alternatives in technology implementation that can use the locally available resources. The changes in residents' mind set through the co-learning processes induced by the contributions of the outsiders, providing professional insights acquired from the analyses and through the interactions with local stakeholders were examined in this study. This study demonstrates that the holistic incorporation of scientific technology assessments into co-learning can help coordinate the collaboration between researchers and local stakeholders toward regional transformation.

“…In the aspect of TSS design, the existing research mainly focuses on the thermal calculation of parts of the TSS, such as separate heat exchangers, heat storage modules, etc. Raczka et al [13] and Fujii et al [14] introduced the design and calculation method of flue gas/waste water-heat exchanger and indirect heat exchanger, respectively. Du et al [15] also reported a design method for heat storage units.…”

Electric heating and solid thermal storage systems (EHSTSSs) are widely used in clean district heating and to flexibly adjust combined heat and power (CHP) units. They represent an effective way to utilize renewable energy. Aiming at the thermal design calculation and experimental verification of EHSTSS, the thermal calculation and the heat transfer characteristics of an EHSTSS are investigated in this paper. Firstly, a thermal calculation method for the EHSTSS is proposed. The calculation flow and calculation method for key parameters of the heating system, heat storage system, heat exchange system and fan-circulating system in the EHSTSS are studied. Then, the instantaneous heat transfer characteristics of the thermal storage system (TSS) in the EHSTSS are analyzed, and the heat transfer process of ESS is simulated by the FLUENT 15 software. The uniform temperature distribution in the heat storage and release process of the TSS verifies the good heat transfer characteristics of the EHSTSS. Finally, an EHSTSS test verification platform is built and the historical operation data of the EHSTSS is analyzed. During the heating and release thermal process, the maximum temperature standard deviation of each temperature measurement point is 28.3 °C and 59 °C, respectively. The correctness of the thermal calculation of the EHSTSS is thus verified.
