Abstract
The rising demand for energy in the face of declining fossil fuel reservoirs requires a transition towards renewable alternatives. Among them, biofuels have emerged as promising solutions, with microalgae-based biofuels attracting considerable attention. Microalgae, characterized by their rapid growth, efficient photosynthesis and high lipid content, offer a sustainable source for biofuel production. Unlike traditional energy crops, microalgae cultivation alleviates concerns regarding land use and food prices. Moreover, they excel in diverse environmental conditions, exhibiting remarkable productivity and versatility in biofuel synthesis. The production process involves cultivation, harvesting and oil extraction, followed by trans-esterification to obtain biodiesel. Additionally, microalgae present opportunities for bio-ethanol and bio-hydrogen production through fermentation and photolysis processes. Anaerobic digestion further transforms microalgae into biogas, underscoring their potential as a comprehensive bioenergy source. This article explores the cultivation techniques, harvesting methods and conversion processes integral to harnessing microalgae for sustainable biofuel production, offering insights into the future of renewable energy.
