The increasing demand for petroleum based fuels, global warming and environmental pollution has driven the world to search for newer, safer and cleaner sources of fuel. Also, the transportation sector in India is dependent on petroleum and other non-renewable sources of energy. In view of the increased attention to climate change, there is a renewed focus on alternative fuels. Algae have recently received a lot of attention as a new biomass source for the production of renewable energy. Some of the main characteristics which set algae apart from other biomass sources are that algae (can) have a high biomass yield per unit of light and area, can have a high oil or starch content, do not require agricultural land, fresh water is not essential and nutrients can be supplied by wastewater and CO2 by combustion gas. This paper investigates the ABB production techniques available to holds future promise for developing countries like India.
