Algaeculture: An Alternative to Solving Energy Sustainability Crises in Developing Countries

Abstract

There is an impending need to reduce the dependency on fossil fuels in these areas of the world considering the ever depleting conventional oil resources and climate change, induced by greenhouse gas emissions. Algae are currently being prompted as a potential next generation bioenergy feedstock due to the fact that they do not compete with food or feed crops. They also produce much higher areal oil yields than the current agricultural crops. They can be produced on barren lands and have broad bioenergy potentials as they can be used to produce liquid transportation and heating fuels such as biodiesel and ethanol, or anaerobically digested to produce biogas. Algae are fast growing organisms capable of fixing high amount of carbondioxide through photosynthesis to produce biomass. Diverse technologies are currently being pursued to produce algae for bioenergy applications. The successful culture of algae could serve as a solution to the impending energy crises in both developed and developing countries.
