About this Research Topic

Background

Concentrating Solar Thermal (CST) technologies are pivotal in the transition to renewable energy, providing a highly efficient method to harness and convert solar energy into thermal and electrical power. These systems, which include parabolic troughs, solar power towers, and linear Fresnel reflectors, utilize solar concentrators to focus sunlight onto a small area, achieving the high solar flux required for various applications, i.e., solar thermal, solar membrane distillation, solar hydrogen production, etc. CST technologies are instrumental in addressing the global energy demand while mitigating the environmental impact associated with fossil fuels. As the pursuit of sustainable energy solutions intensifies, the refinement and enhancement of CST systems become imperative. These advancements not only improve the efficiency and scalability of solar energy capture but also contribute to diverse applications such as solar desalination, solar hydrogen production, and integration with other renewable energy sources, underscoring the broad potential of CST technologies in the renewable energy landscape.

The primary objective of this research topic is to address the challenges faced by Concentrating Solar Thermal (CST) technologies and enhance their performance. While CST systems hold great promise, they encounter various barriers that hinder widespread adoption and optimal efficiency. These challenges include the need for cost-effective and durable materials for solar receivers, improvements in the efficiency of heat transfer fluids, and the optimization of solar concentrator designs to maximize sunlight capture and concentration. Additionally, enhancing thermal energy storage solutions is crucial to ensure the reliable and uninterrupted energy supply, particularly during periods of low solar irradiance.

To achieve these goals, this research topic seeks to encourage collaboration among researchers, industry experts, and academics to explore innovative solutions and advancements in CST technologies. By investigating new configurations of solar concentrators and receivers, developing advanced materials and coatings, and researching new thermal storage methods, we aim to significantly improve the efficiency, scalability, and economic viability of CST systems. Moreover, the integration of CST technologies with other renewable energy sources and applications, such as solar desalination and solar hydrogen production, can further enhance the energy efficiency. Through rigorous research and collaboration, we aim to address current limitations and unlock the full potential of CST technologies.

The scope of the research topic includes, but is not limited to, the following themes:

• Concentrating solar thermal designs: Research on novel configurations of solar concentrators and solar receivers to enhance efficiency and scalability. Development and optimization of advanced heat transfer fluids to improve efficiency and stability in CST systems.
• Materials and coatings for solar receivers: Studies on advanced materials and coatings that enhance the performance, durability, and cost-effectiveness of solar receivers, with a focus on high-temperature resistance and anti-corrosive properties.
• Optics of concentrators: Investigations into the optical properties of concentrators, optimizing their design to maximize sunlight capture and concentration.
• Thermal energy storage: Exploration of thermal storage methods, including the use of phase change materials, sensible and thermochemical storage to store excess solar energy for later use, ensuring a continuous energy supply.
• Integration with other renewable technologies: Studies on integrating CST systems with solar photovoltaic technologies and other renewable energy sources to create hybrid systems, enhancing overall energy efficiency.
• Solar desalination: Research on the application of CST technologies in solar desalination and membrane distillation processes, addressing global water scarcity issues.
• Solar hydrogen production: Innovations in using CST systems for solar hydrogen production contribute to the development of clean fuel alternatives.
• Thermal management and thermodynamics: Analysis of thermal management strategies to optimize heat transfer and thermodynamic efficiency in CST systems.
• Solar cookers and practical applications: Case studies on the use of solar cookers and other practical applications of CST technologies, highlighting real-world implementations.
• Economic and environmental impact: Assessments of the economic viability and environmental benefits of CST technologies, focusing on cost reduction strategies and lifecycle analyses.

We are interested in original research articles, case studies, and reviews that contribute to the advancement of CST technologies. Manuscripts should present innovative research, insightful analyses, or practical applications related to the themes outlined above.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
