In the drive towards a sustainable future, the energy sector is pivoting to zero-carbon and low-carbon fuel alternatives such as hydrogen, ammonia, biofuels, and synthetic fuels. This shift is crucial for the global quest for carbon neutrality. As these novel fuels take center stage, there is a profound need to understand their combustion behavior, thermal performance, and efficiency. Current research predominantly focuses on improving the efficacy of such fuels in combustion engines and power generation systems. Recent breakthroughs have offered promising insights, yet significant gaps remain, particularly in optimizing flame dynamics, emissions control, and overall system efficiency.

This Research Topic explores the combustion efficiency and thermal utilization of zero-carbon and low-carbon fuels, including the latest methodologies and technologies. By addressing critical areas such as emission reduction, energy conversion, and system stability, this Research Topic seeks to expand current knowledge and contribute to the ongoing efforts to enhance the development of zero-carbon and low-carbon fuels.

We welcome articles addressing, but not limited to, the following themes:
• Fundamental studies on combustion characteristics of zero-carbon and low-carbon fuels
• Investigations into flame dynamics, pollutant formation (e.g., NOₓ, particulates), and climate-forcing metrics such as contrails
• Exploration and application of advanced combustion technologies for improved thermal efficiency
• Comprehensive computational and experimental studies on fuel reactivity and ignition processes
• Safety, stability, and operational challenges in using emerging low-carbon fuels
• Developments in emission control strategies
• Studies on cost trajectories, regulatory frameworks, and infrastructure requirements
• Applying laboratory findings to real-world scenarios.
