Summary: The future of power generation is expected to rely more on renewable energy, which presents a challenge in matching intermittent supply with demand. The use of latent thermal energy storage with phase change materials (PCMs) can address this issue. However, the low thermal conductivity of PCMs limits the energy storage rate. In this study, a flow structure-informed fin configuration for triplex-tube heat exchangers (TTHXs) was designed and optimized to accelerate the melting process of PCMs. Results showed that the optimized fin geometry reduced the melting time by 57.4%, demonstrating the effectiveness of fins in reducing PCM melting times.

Summary: This study investigates the influence of inlet velocity and temperature of the heat transfer fluid (HTF) on the phase transition process of phase change material (PCM) in a latent heat thermal storage (LHTS) system with metal foam. A novel multi-channel LHTS tank is designed and a three-dimensional numerical model is established to describe the transient melting process. Additionally, a new LSTM-BP neural network is developed to predict the behavior of the PCM based on HTF inlet velocity, temperature, and time. The results demonstrate that increasing the HTF velocity or temperature reduces the melting time of the PCM. The machine learning model provides new adaptive approaches for thermal storage design and operation.

Summary: This study focuses on improving the thermal conductivity of phase change materials in order to enhance the performance of a square latent heat storage device. The addition of fin and foam metal reduces the complete melting time of the phase change materials and increases temperature uniformity. However, it also leads to a decrease in total heat storage. Dynamic temperature studies further investigate the effect of fins and metal foam on the internal melting process.

Summary: In this study, the flip mechanism is applied to improve the characteristics of uneven melting in the melting process of the triplex-tube latent heat energy storage unit. Numerical simulation is used and verified by experimental data. The results show that a single flip can significantly improve the melting performance of the unit under different dimensionless times. However, the flip has a negative effect on the total heat absorption in one melting cycle. The addition of flip effectively reduces the negative influence of the hard-to-melt zone during the melting process.

Summary: This study proposes a solar power plant with multiple combinations, including photovoltaic (PV) plants, thermal storage systems (TES) and batteries. By conducting multi-objective optimization, it is found that, in the current economic scenario, combinations including TES have better economy and reliability, and integrating CSP into PV systems can most economically improve reliability. With the reduction of energy storage costs, there is a competitive relationship between batteries and TES, but solar power plants with integrated CSP remain effective in enhancing generation reliability. In cost-reduction scenarios, batteries gradually show their advantages and integrating batteries into PV plants becomes more competitive.
