The world faces pressing environmental challenges, including greenhouse gas emissions, global warming, climate change, and rising sea levels. Alongside, these issues, the depletion of fossil fuels has intensified the search for alternative energy sources. Algal biomass presents a promising long-term solution to these global problems. The quest for sustainable energy has driven significant research into algal biofuels as a viable alternative to fossil fuels. Algae offers several advantages as a feedstock for biofuel production, including high biomass yield, rapid growth rates, cost-effective cultivation, carbon dioxide fixation capabilities, and the potential to grow on non-arable land using non-potable water. This manuscript provides an overview of algal biomass cultivation using renewable feedstocks, identifies potential algal strains for biofuel production, and explores bioengineering advancements in algae. Additionally, strain improvement strategies to enhance biofuel yields are discussed. The review also addresses large-scale algal biomass cultivation for biofuel production, assesses its commercial viability, examines challenges faced by the biofuel industry, and outlines prospects for biofuel production using highly potent algal strains. By overcoming and addressing these challenges, algal biofuels have the potential to become a cornerstone of sustainable energy solutions.
