Summary
Trigeneration (combined cooling, heating, and power, CCHP) systems are among the most promising solutions for increasing overall energy conversion efficiency, as they allow the simultaneous generation of electricity, heat, and cold from a single primary energy source. Integrating such systems with renewable resources, particularly solar and wind energy, further reduces greenhouse gas emissions and dependence on fossil fuels, which is especially relevant for regions with high solar irradiation and wind potential, such as Central Asia. Despite considerable progress, the efficiency of hybrid trigeneration systems remains limited by challenges in energy storage, load matching, and system optimization, which calls for continued research in this field.
This Special Issue aims to bring together original research and review articles addressing the design, modeling, optimization, and operational performance of trigeneration systems based on green energy technologies. The scope covers theoretical, numerical, and experimental studies on solar- and wind-assisted trigeneration, hybrid renewable energy systems, thermal and electrical energy storage, control and optimization strategies, and techno-economic and environmental assessments aimed at improving the overall efficiency and reliability of such systems.
Suggested themes include, but are not limited to:
- Trigeneration (CCHP) systems integrated with solar and wind energy
- Thermodynamic modeling and performance optimization of trigeneration cycles
- Hybrid renewable energy systems for combined heat, cold, and power supply
- Thermal and electrical energy storage technologies for trigeneration systems
- Control, automation, and smart management of trigeneration systems
- Techno-economic and environmental (life-cycle) analysis of green trigeneration systems
- Case studies and pilot projects of trigeneration systems under various climatic conditions
