About this Research Topic
With the intensification of climate change issues and the serious environmental burden caused by the use of traditional fossil fuels, the development and adoption of sustainable energy solutions have become urgent. Among the various renewable energy sources, hydrogen is considered a highly potential clean energy carrier due to its unique advantages, and it has been attracting increasingly more attention globally in recent years. Advanced Hydrogen Combustion Technology (AHCT) represents a key direction in the use of hydrogen energy. Compared to other hydrogen utilization methods, hydrogen combustion has advantages such as high energy density, wide applicability, and strong adaptability to existing power equipment. This special research topic is dedicated to exploring the latest advancements, challenges, and future directions in the field of advanced hydrogen combustion technology, with a focus on developing efficient, safe, scalable and clean hydrogen combustion methods that have the potential to completely transform the global energy system.
In this Research Topic, we aim to address the complex challenge of efficiently and safely harnessing hydrogen as a clean energy source through Advanced Hydrogen Combustion Technologies (AHCT). The core problem revolves around improving the efficiency and safety measures of hydrogen combustion processes to ensure they can be feasibly integrated into existing energy infrastructures and meet the growing global energy needs in an environmentally sustainable manner. Achieving this involves overcoming the intrinsic challenges associated with hydrogen, including its high diffusivity, high flame speed, low ignition energy, thermo-diffusive instabilities, and the need for advanced containment and control technologies to prevent unwanted leakage, ignition and high NOx emission.
The scope of the Research Topic includes the issues related but not limited to:
• Hydrogen Combustion Reaction Kinetics;
• Hydrogen Flame Dynamics;
• Hydrogen Combustion Applications Including Engines, Gas Turbines, and Rocket Engines;
• Hydrogen Combustion in Micro Combustor;
• Hydrogen Detonation;
• High-Fidelity Numerical Simulation Research on Hydrogen Combustion;
• Emission Control of Hydrogen Combustion (eg.NOx).
