Abstract
Present industrialization and global mobility era is an energy intensive period of the human history with
an ever increasing energy demand. Unfortunately, fossil fuels are no more sustainable due to growing gap
between the demand and supply. Biofuels are considered as promising alternative liquid fuels in recent
global energy scenario. Food crops and ligno-cellulosic plant biomass have been widely studied as an
alternative feedstock for biofuels production. After decades of research, the competition of fuel with food
and recalcitrant nature of plant biomass, these feed stocks are losing their popularity. Marine macroalgae
have come forward as another potential feedstock for biofuels production. Marine algae have several
advantages over the traditional energy crops including absence of lignin, higher growth rates and no
competition with human food. Moreover, along with several environmental benefits, they can be grown
using saline and waste water and have higher abilities to sequester the atmospheric CO2 than traditional
energy crops. Although there are several challenges associated with the algal biomass conversion to
bioenergy yet these problems can be overcome using integrated biorefinery approach.
