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.
