The Potential of Algae Biofuel as a Renewable and Sustainable Bioresource †

Abstract

Algae are promising sources of biofuel. Microalgae’s ability to grow quickly with photosynthesis, carbon dioxide, and nutrients makes them ideal biofuel sources that do not compete for resources with food crops like corn. Algae cultivation on non-arable land allows it to produce biofuel while not competing with them for resources. Algae biofuel has many advantages over fossil fuels, including reduced greenhouse gas (GHG) emissions and carbon emissions. There are various methods for turning algal feedstock or biomass into advanced biofuels. Algae biofuels have become widely used as fossil fuel replacements; however, several challenges must still be overcome, such as high production costs, the need for extensive growing systems, harvesting techniques that enable efficient harvesting/extraction techniques, as well as efficient harvesting/extraction technologies.
