Industrialization and globalization have increased the demand for petroleum
products that has increased a load on natural energy resources. The escalating fossil fuel
utilization has resulted in surpassing the Earth's capacity to absorb greenhouse gases, necessitating
the exploration of sustainable bioenergy alternatives to mitigate emissions.
Biofuels, derived from algae, offer promising solutions to alleviate fossil fuel dependency.
Algae, often regarded as third-generation biofuels, present numerous advantages owing
to their high biomass production rates. While algae have been utilized for their bioactive
compounds, their capability as biomass for the production of biofuel has gained traction
among researchers. Various biofuels such as bio-hydrogen, bio-methane, bio-ethanol,
bio-oil, and bio-butanol can be derived from algae through diverse processes like fermentation,
photolysis, pyrolysis, and transesterification. Despite the enormous commercial
potential of algae-derived biofuels, challenges such as high cultivation costs persist.
However, leveraging the utilization of algae byproducts could improve economic viability
of biofuel production. Moreover, algae derived biofuels offer environmental sustainability,
cost-effectiveness, and waste reduction benefits, promising novel opportunities for
a more sustainable energy future. Moreover, advancements in the field could lead to patents
that drive innovation and commercialization in algae-based biofuel technologies.
