Mission of this page is to aware people about the energy scarcity and understand them the importance of biofuels, specially biodiesel. Awareness to the damages modernization has caused to the environment is growing rapidly and has triggered a worldwide search for ways to protect the environment and its critical resources.
The rapid depletion of fossil based fuels, their over increasing costs and the environmental pollution caused by burning these fules have led intensive search for substitute fuels. Oilgae and can be taken as a next generation biofuel. Up to 70% of algal biomass has usable oils. Microalgae does not compete for land and space with other agricultural crops. Microalgae can survive in water of high salt concentration and use water that was previously deemed as unusable. Algae presents multiple possibilities of fuel and other products as biodiesel, ethanol, methane, jet fuel, biocrude and more via a wide range of processes. Algae produce higher biomass and oil yielding than conventional energy crops, and they can be on marginal land or in seawater. Additional benefits can be achieved from co-production food, feed and high-value chemicals as well as from environmental services, such as bio-fixation of CO2 and wastewater treatment. However, biotechnical, environment, and economic challenges, need to be overcome for large scale production of oilgae which can be economically feasible. Major bottlenecks are high cultivation and harvesting costs, unfavorable energy balance, and the demand of nutrients. Long-term R&D in biotechnology is needed to develop systems for production of sustainable oilgae. Moreover, the availability of demands such as nutrients for mass algae cultivation sites are identified. Some transgenic verities can enhance the production of oil content from algae.
