Innovative Approaches to Low- and Zero-Carbon Fuel Engines: Efficiency and Challenges

Low- to zero-carbon fuels, including biofuels and their blends, are essential for developing sustainable energy systems and serve as effective alternatives to fossil fuels. The infrastructure requirements and economic challenges associated with zero-carbon options, such as hydrogen, highlight significant barriers to their widespread adoption. Innovative efforts in this field aim to transform how both low and zero carbon fuels can effectively replace traditional internal combustion engines. Recent studies have begun to reveal the potential of hydrogen engines, measuring their brake thermal efficiency and comparing it to conventional fuels. While these advancements demonstrate promising progress, challenges related to cost competitiveness and infrastructure development remain critical hurdles to overcome.This Research Topic aims to develop a comprehensive understanding of low- to zero-carbon fuels, including biofuels and their blends, by examining their operational efficiency and scalability challenges. It will explore key questions regarding the efficiency levels achievable with these fuels and their compatibility with, or superiority over, conventional engines. Additionally, the goal includes evaluating the economic and environmental impacts of adopting low to zero carbon fuel technologies across the automotive and energy sectors, providing insights into their potential for fostering sustainable development.To enhance our understanding of the complexities involved in implementing engines powered by low- to zero-carbon fuels and biofuel blends, this call for papers focuses on both fundamental studies and advanced applications.We invite contributions that explore a range of themes, including:• Experimental, computational, and AI-driven analyses of efficiency and emissions in low to zero carbon fuel and biofuel engines;• Economic evaluations related to the scalability of zero carbon fuels, such as hydrogen, including infrastructure and storage solutions;• Innovative engineering solutions that address challenges in fuel systems, air handling, and aftertreatment for low to zero carbon fuel engines.Additionally, we encourage the submission of Original Research Articles, Review Articles, Mini Reviews, and Perspectives that discuss recent advancements and practical challenges in the technologies of low- to zero-carbon fuels, including biofuels and their blends.
