Sustainable Fuel Additives Derived from Renewable Resources: Promising Strategies for a Greener Future

Abstract

In the current era of energy transition, the development of synthetic fuel production pathways has revolutionized the prospects for sustaining carbon-based hydrocarbon fuels in the transportation sector. Notably, technologies such as Power-to-X (PTX) and biofuels have emerged as promising solutions, fostering cleaner fuels with reduced carbon intensity. However, it is imperative to note that synthetic fuels like e-gasoline, e-ATF, and e-diesel generated via PTX methods, along with biofuels, may possess distinct physiochemical properties compared to their conventional crude oil-derived counterparts. Achieving the requisite fuel quality, performance standards, and adherence to stringent environmental regulations demands the incorporation of environmentally friendly additives. This review aims to offer a comprehensive review of potential green additives for use in synthetic and biofuels, ensuring that they meet necessary fuel properties and performance criteria. This approach not only addresses the immediate need for cleaner transportation fuels but also aligns with the global imperative of achieving net-zero emissions targets.
