Algae as a Feedstock for Bioethanol and Biomethane Production

  • Chapter
  • First Online:
Novel Feedstocks for Biofuels Production

Part of the book series: Clean Energy Production Technologies ((CEPT))

  • 308 Accesses

Abstract

The current energy demands and depleting fossil fuel reserves have generated a need for searching alternative renewable fuels. This has prompted scientists worldwide on systematically researching third-generation biofuels, bioethanol and biomethane, as a suitable alternative. Algae, a renewable fuel generating biomass, are rich in macromolecules such as carbohydrates, lipids and proteins. Due to the sustainability of the feedstock and environmentally friendly nature, biofuels produced from algal biomass are becoming increasingly popular. This chapter discusses bioethanol and biomethane production from algal biomass using different cultivation, harvesting and extraction techniques. Focus was also given to biochemical and genetic engineering approaches and life cycle assessment studies to increase biofuel production from algae. Overall, the chapter unravels how blending these practices can improve the utilization of algal biomass to develop biofuels and establish it as a promising future energy feedstock.
