Description
Sustainability is paramount to preserving essential resources for future generations. The widespread use of fossil fuels generates significant pollution, severely impacting both terrestrial and aquatic ecosystems through phenomena such as acid rain. Despite their rapid growth, high photosynthetic efficiency, and ability to thrive in a variety of conditions, algae have become a viable alternative biomass feedstock for biofuel production. This review explores the efficiency and scalability of algae-based biofuels, focusing on key factors such as biomass yield, lipid content, and conversion technologies. Algae have a higher lipid yield compared to traditional biofuel feedstocks such as corn or soybeans, making them an attractive option for large-scale fuel production. However, several obstacles hinder the widespread adoption of algae-based biofuels, including high production costs, energy-intensive cultivation, and water consumption. This paper also examines the efficiency and suitability of various cultivation technologies, including open ponds and photobioreactors, for large-scale production. Algal biofuel production could become more economically viable and environmentally sustainable through the integration of carbon capture technology and wastewater treatment. Advances in genetic engineering and metabolic optimization are further increasing lipid productivity, offering promising prospects for large-scale applications. This review additionally provides an analysis of genetic engineering techniques aimed at increasing biofuel yields. The study emphasizes the potential of algae-based biofuels to serve as environmentally friendly alternatives to traditional fossil fuels, highlighting these innovative approaches. While the evaluation acknowledges that algae-based biofuels can reduce dependency on fossil fuels and help mitigate climate change, it also notes that further research and development are necessary to overcome current financial and technological challenges. This review explores the recent advancements in algae cultivation, harvesting techniques, and biofuel extraction processes. Its goal is to present a comprehensive understanding of the current state of algae as a sustainable and effective feedstock for biofuel production, along with future prospects. 2025 Elsevier B.V.
