Amidst the aggravation of the worldwide environmental crisis driven by persistent climate change, there is an escalating urgency to find environmentally sustainable solutions for contemporary challenges. A significant contributor to climate change is the elevation in atmospheric pollutant concentrations resulting from the emissions of conventional fuel combustion in internal combustion engines. Consequently, the imperative to create fuels to meet environmental requirements has led to the development and implementation of technologies dedicated to the production of alternative fuels. This article offers a comprehensive overview of the primary alternative fuels suitable for internal combustion engines, along with an exploration of the benefits associated with their utilization.
