Special Session III

Economic-Technical Research on Wind-Solar-Hydrogen-Cooling Energy System

With the increasingly prominent environmental and climate change issues, renewable energy sources such as PV/wind are gradually becoming the core content of the energy transformation. However, the output of PV/wind is often random. The use of energy storage is an effective way to solve the intermittent output of wind and solar power and avoid the imbalance between power supply and demand. As clean energy and the main energy source in the future, hydrogen has the advantages of wide sources, clean and pollution-free. Hydrogen storage has an absolute advantage in terms of energy storage density and storage time among the existing energy storage. In addition to hydrogen storage, cold storage is another type of energy storage that deserves attention. A large percentage of regions rich in renewable resources have hot climates, which means the power consumption of local businesses is usually used for cooling. Cold storage has the advantage of being cheaper and has a longer life. It may be the option of entirely or partially replacing the battery. Therefore, the wind-solar-hydrogen-cooling system has excellent prospects for solving the shortage of fossil energy and environmental pollution. This special session aims to offer an opportunity for researchers and practitioners to identify new promising research directions on the wind-solar-hydrogen-cooling energy system and provide a forum to disseminate and discuss hydrogen/cooling energy storage. We hope to help the audience have deeper insights into hydrogen/cold storage roles in the power sector.

The topics of interest include, but are not limited to:
• Carbon-neutral and wind-solar-hydrogen-cooling energy system
• Research on technology to improve wind-solar-hydrogen-cooling grid-connected performance
• Research on wind-solar-hydrogen-cooling energy system planning and design considering the volatility of renewable energy
• Application of artificial intelligence in wind-solar-hydrogen-cooling systems
Simulation design and modeling analysis of hydrogen production by electrolysis and cold energy storage
Comparative study of energy systems with different energy storage
Research on the adaptability of wind-solar-hydrogen-cooling systems
Research on hydrogen development and utilization
Comparative study of chilled water and ice as the storage medium
