Abstract

Approximately 80 percent of the global energy needs are met by fossil fuels. Excessive reliance on these fuels has led to environmental pollution, climate change, and health problems for all living beings. Thus, identifying alternative energy sources is crucial to meeting global energy demands and reducing environmental pollution. It is expected that energy from cost-effective renewable resources will power the world’s energy systems in the future. Algae biomass has become a promising source for biofuel, as biofuels derived from microalgae are biodegradable, renewable, and more environmentally friendly compared to fossil fuels. Microalgae are a more sustainable option for biofuel production than traditional biofuel sources because of their high lipid content, rapid growth rates, and capacity to thrive in non-arable land. The processes of microalgae cultivation, harvesting, lipid extraction, and conversion to biodiesel are critically examined in this paper, which also discusses the technological and economic barriers to large-scale implementation. The necessity for effective cultivation systems, the high cost of harvesting and extraction technology, and the need for significant nutrients are the main problems. The findings highlight the need for more study and technological developments to improve the viability of microalgae biofuels, establishing them as an essential part of future renewable energy plans meant to mitigate climate change and advance sustainability

Keywords: Microalgae, biofuels, renewable energy, alternative fuels, climate change, sustainability
