Special Issue Information

Dear Colleagues,

New energy sources, which mainly include solar, wind, hydrogen, geothermal, biomass and nuclear energies, are meaningful for promoting the sustainable development of the world. Currently, different types of new energy systems are at different development stages, facing different kinds of challenges and issues. For instance, how can we increase energy efficiencies of new energy systems? How can long-term stable power be generated using renewable energies? Are new types of multi-energy complementary systems feasible in the future? How can we further develop the potential of new energy systems to make them become polygeneration systems? Researchers all over the world are working hard on finding effective methods of meeting these challenges and solving these issues.

This Special Issue aims to provide a platform for researchers to discuss the relevant issues in thermal analysis and thermodynamic analysis for advanced new energy systems, allowing them to present the latest achievements in new energy utilization technologies as well as to propose corresponding solutions to key technical challenges of new energy systems. This Special Issue encourages original research works and literature review articles on thermal analysis and thermodynamic analysis for advanced new energy systems, with topics including but not limited to the following:

  1. Designs and thermodynamic analyses of novel new energy systems, including solar energy systems, wind power systems, biomass energy systems, geothermal energy systems, nuclear energy systems, multi energy hybrid systems, etc.;
  2. Thermal economic analyses of new energy systems;
  3. Thermodynamic analyses in new energy-based hydrogen production or desalination;
  4. Flow and heat transfer analyses in new energy systems;
  5. Energy storage issues in new energy utilization;
  6. Other thermal analysis and thermodynamic analysis issues in new energy utilization.

An innovative solar concentrating beam splitting photovoltaic thermal (CBS-PVT) system using a half-trough concentrator (HTC) and a film spectrum filter (FSF) is proposed and studied in this study. The FSF used for this system is designed and its average reflectivity and transmissivity are 0.272 and 0.728 for the full spectrum range. Performance evaluation results of the CBS-PVT system reveal the design correctness of the system. When the N-S solar tracking error (STE) rises to 0.15°, the optical efficiency of the entire CSB-PVT system can be kept at 0.8653, showing good adaptable capacity to the STE. The operation feasibility analysis shows that the PV efficiency of the PV subsystem (PVS) is 0.314 and the overall system efficiency overall is 0.26. Parametric analysis results indicate that when the solar thermal collector tube (TCT) operating temperature rises, the total power and overall efficiency of the CSB-PVT system both rise first and then decrease. When the TCT temperature is about 225 °C, the CBS-PVT system reaches its maximum output power of 1003.6 W and the maximum overall efficiency of 0.261. When the PV cell module (PVCM) temperature increases, the total power and overall efficiency of the CBS-PVT system decrease linearly. When the PVCM temperature rises to 50 °C, the two parameters decrease to 952.9 W and 0.248. Full article
