Manuscript Submission Deadline 30 November 2022

There is an increase in the consumption of fossil fuels for power generation and heating purposes, which is causing global warming and other environmental problems. To proceed securely into the future, it is necessary to develop effective heating and power generation techniques based on renewable energy. Wind, geothermal, solar, and ocean thermal energy, and others, are among the renewable energy sources that can be used to replace fossil fuel-based systems. Among these, solar energy is regarded as one of the most abundantly available and conveniently accessible renewable energy sources. Consequently, solar thermal and solar power technologies are two of the major ways to harvest solar energy. Especially, solar thermal technologies have been employed for a wide range of purposes, such as heating and cooling buildings, drying fruits, vegetables, and herbs, heating water for industrial and domestic purposes, heating swimming pools, operating pumps and engines, driving refrigerators, generating electricity, and desalinating water, among many others.

However, efficiently utilising the incoming solar energy for the aforementioned purposes is not a simple task. In the past decade, numerous researchers have worked to improve the thermal efficiency and overall performance of solar thermal systems operating at low, medium, and high temperatures. In comparison to typical fossil fuel-based systems, this system is unreliable due to issues such as intermittent solar radiation, system inactivity during non-sunlight hours, and unpredictable performance due to seasonal/climatic/location changes.

This Research Topic is intended to examine the innovative recent advancements in enhancing the performance and reliability of low, medium, and high temperature solar thermal technologies, including solar flat plate collector, parabolic trough concentrator, compound parabolic concentrator, solar parabolic dish concentrator, and other CSP (concentrating solar power) technologies employed for desalinating sea/brackish water, drying fruits, vegetables, and herbs, vapour absorption refrigeration systems, thermoelectric power generation, etc. Furthermore, thermal energy storage materials (sensible and latent heat) utilised to store excess energy during the daytime and use it at night-time for the aforementioned applications also been explored.

The scope of this Research Topic includes but is not limited to:

• Enhancement of drying rate and operation time of solar dryer.
• Receiver configuration of a solar parabolic dish concentrator
• Utilization of naturally available materials in solar still desalination
• Industry effluents utilization for solar dryer and solar desalination
• Hybridization of solar thermal and solar PV/CPV technologies for simultaneous heating and electrical power production
• Numerical studies of the solar thermal energy system
• Predicting the performance of the solar thermal system based on the previous data using Machine Learning (ML) techniques such as Artificial Neural Networking (ANN).
• Solar refrigeration

Keywords: Solar energy, solar thermal, solar dryer, solar desalination, thermal energy storage, thermoelectric power generation, Artificial Neural Networking, Solar refrigeration, Solar PV


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
