ALGAL BIOFUELS: A SUSTAINABLE WAY FOR FUTURE ENERGY NEEDS
Dr. Shalu Tyagi* and Dr. Abha Dubey
ABSTRACT
Increasing global energy demand at a rate faster than the population growth has led the researchers to look for alternative fuel. The current fossil fuel reserves are not sufficient to meet the increasing demand and very soon be depleted irreversibly. Pollution, global warming, and turbulent oil prices have led the quest for renewable and carbon neutral energy sources. Algal bio-fuels represent a potential source of renewable energy. Algae, as the third generation feedstock, are suitable for biodiesel and bioethanol production owing to its’ rich energy (lipid and carbohydrate) content, high growth rate, excellent biomass yield, inexpensive culture approaches, the notable capacity of CO2 fixation and O2 addition to the environment. Lately, there is an increasing research interest for the advancement of biofuel technologies. With their huge potential, algae are expected to surpass the first and second generation feedstocks hence can thus be used for increased biofuel production. This paper aims to analyze the integration approaches for sustainable micro algal biofuel production to meet the future energy needs of the society.
