The expanding use of fossil fuels has caused concern in terms of both energy security and environmental issues. Therefore, attempts have been made worldwide to promote the development of renewable energy sources, among which biofuel is especially attractive. Compared to other biofuels, lipid-derived biofuels have a higher energy density and better compatibility with existing infrastructure, and their performance can be readily improved by adjusting the chemical composition of lipid feedstocks. This review thus addresses the intrinsic interactions between lipid feedstocks and lipid-based biofuels, including biodiesel, and renewable equivalents to conventional gasoline, diesel, and jet fuel. Advancements in lipid-associated biofuel technology, as well as the properties and applicability of various lipid sources in terms of biofuel production, are also discussed. Furthermore, current progress in lipid production and profile optimization in the context of plant lipids, microbial lipids, and animal fats are presented to provide a wider context of lipid-based biofuel technology.
化石燃料的广泛使用引起了人们对能源安全和环境问题的关注。因此，全世界都在努力推动可再生能源的发展，其中生物燃料尤其具有吸引力。与其他生物燃料相比，脂类衍生生物燃料具有更高的能量密度，并且与现有基础设施的兼容性更好，通过调整脂质原料的化学成分，其性能可以很容易地得到改善。因此，本综述讨论了脂质原料与基于脂质的生物燃料（包括生物柴油）以及传统汽油、柴油和喷气燃料的可再生替代品之间的内在相互作用。还讨论了与脂质相关的生物燃料技术的进展，以及各种脂质来源在生物燃料生产方面的特性和适用性。此外，还介绍了植物脂类、微生物脂类和动物脂肪中脂质生产和谱优化的当前进展，为脂质基生物燃料技术提供了更广泛的背景。
