Advanced Analysis of Thermodynamic and Thermal Energy

Dear Colleagues,

Thermodynamic and thermal energy technologies play a fundamental role in modern energy systems, from traditional power generation to newly emerging clean-energy infrastructures. With the global transition toward sustainable and low-carbon development, increasing attention is devoted to high-efficiency conversion, advanced thermal management, and multi-energy integration. Rapid progress in materials, system integration, modelling tools, and control strategies has greatly expanded the capability and applicability of thermodynamic systems. Meanwhile, the accelerating deployment of renewable energy sources, such as solar, wind, and hydropower, together with the fast-growing hydrogen economy and fuel-cell technologies, has presented new challenges in the form of system coupling, stability, safety, and efficiency optimization. These trends have significantly driven research toward advanced analysis techniques for thermodynamic cycles, thermal energy storage, hybrid energy systems, and next-generation clean-energy devices.

Aim and Scope

This Special Issue aims to present and disseminate recent advances in the theory, modelling, design, optimization, control, and integration of thermodynamic and thermal energy systems. Contributions that address innovative concepts, computational and experimental analyses, emerging applications, and system-level solutions across various clean and renewable energy technologies are welcome.

Topics of interest for publication include, but are not limited to, the following:

• Advanced fuel-cell technologies (PEMFC, SOFC, high-temperature fuel cells, and hybrid systems).
• Hydrogen production, storage, transport, and utilization technologies.
• Multi-energy systems based on renewable resources (solar, wind, hydro, geothermal, biomass, etc.).
• Thermodynamic cycle analysis and optimization (Brayton analysis, Rankine analysis, combined cycles, and supercritical CO₂ cycles).
• Optimal design and operation strategies for low-carbon energy systems.
• System-level simulation, digital twins, and data-driven modelling for thermal-energy systems.
• Environmental impact, lifecycle analysis, and emissions reduction technologies.
