The ever increasing energy demands have necessitated the development of alternative energy sources. Unbridled utilization of fossil fuels, coupled with public awareness has directed research focus towards the production of non-polluting and sustainable fuel sources. Algae have garnered tremendous research interest in the present time to meet the challenges faced by existing fuel sources. Ethanol has been widely used since the 1800s as a fuel of choice for internal combustion engines (ICE). Compared to conventional feedstock (corn/sugar beet), microalgae has a better potential in terms of ethanol yield: 40–140 ML ha−1 versus 3–6 ML ha−1 and can be a promising alternative for the future. Although various approaches have been presented to convert algal biomass to fuels, feed and chemicals; none of them are feasible from the economic point of view. Therefore, it is prudent to develop a biorefinery concept where multiple numbers of products can be recovered from the same algal biomass with a limited expense on unit operation. In order to address the present bio-economy challenges, it is pertinent to focus on the development of multiple products from the same biomass. In the present chapter the recent developments on algal refinery concept have been studied focussing on integrated bioethanol production under a biorefinery paradigm. The review also covers the technical challenge which inhibits the realization of algal biorefinery, along with providing insight on how to overcome the technical hurdles.
