Scaling Algae Growth For Co2 Sequestration and Biofuels
Biodiesel derived from microalgae could be looked at as a potential long term replacement for fossil fuels and could meet all transportation needs in the future. The algal feedstock is inherently capable of metabolizing various waste streams such as wastewater and industrial flue gas emissions and can harvest solar energy to yield biofuel and its product derivatives. In this article, simulation of a biochemical plant design with Chlorella sp. serving as the algal feedstock that utilizes industrial by-product CO2 and artificial light for effective production of biodiesel is discussed. The incentive for this research is to analyze the merits of biofuel generation and devise the creation of a more cost effective and environmentally friendly alternative renewable energy source. The process entails growing algae in a bioreactor under predetermined operating conditions and concentrating the resulting biomass. Extracted contents such as proteins, lipids and starch from this biomass are further processed via transesterification to yield the desired biofuel. The simulated design projected a production of 248,000 barrels of biodiesel along with 18,000 barrels of glycerol.
