BACKGROUND: The increasing cost of fossil fuels as well as the escalating social and industrial awareness of the environmental impacts associated with the use of fossil fuels has created the need for more sustainable fuel options. Bioethanol, produced from renewable biomass such as sugar and starch materials, is believed to be one of these options, and it is currently being harnessed extensively. However, the utilization of sugar and starch materials as feedstocks for bioethanol production creates a major competition with the food market in terms of land for cultivation, and this makes bioethanol from these sources economically less attractive.

Microalgae as biomass are a potential source of renewable energy and they can beconverted into energy such as biofuel oil and gas. This paper presents a briefreview on the main conversion process of microalgae becoming energy. Sincemicroalgae have high water content, then not all biomass energy conversion processescan be applied. By using thermochemical process it can be produced oil and gas,and by using biochemical process it can be produced ethanol and biodiesel. Theproperties of microalgae product is almost similar to offish and vegetables oil andtherefore it can be considered as a substitute of fossil oil.

“…Depending upon the strain and composition of the algal species significant yields of ethanol can be produced from algal biomass [77][78][79][80]. Strains with filamentous cells such as Spirulina and Spirogyra are considered most promising due to the higher percentage of carbohydrate in their make-up.…”

Abstract:Research investigating the potential of producing biofuels from algae has been enjoying a recent revival due to heightened oil prices, uncertain fossil fuel sources and legislative targets aimed at reducing our contribution to climate change. If the concept is to become a reality however, many obstacles need to be overcome. Recent studies have suggested that open ponds provide the most sustainable means of cultivation infrastructure due to their low energy inputs compared to more energy intensive photobioreactors. Most studies have focused on strains of algae which are capable of yielding high oil concentrations combined with high productivity. Yet it is very difficult to cultivate such strains in open ponds as a result of microbial competition and limited radiation-use efficiency. To improve viability, the use of wastewater has been considered by many researchers as a potential source of nutrients with the added benefit of tertiary water treatment however productivity rates are affected and optimal conditions can be difficult to maintain year round. This paper investigates the process streams which are likely to provide the most viable methods of energy recovery from cultivating and processing algal biomass. The key findings are the importance of a flexible approach which depends upon location of the cultivation ponds and the industry targeted. Additionally this study recommends moving towards technologies producing higher energy recoveries such as pyrolysis or anaerobic digestion as opposed to other studies which focused upon biodiesel production.
