The shortage of sustainable energy and the extensive environmental pollution along with the global warming effect caused by CO2 emissions are major problems facing the world today. The use of microalgae to overcome these problems has gained enormous research interests in recent years, primarily...

Microalgae represent a sustainable energy source because of their high biomass productivity and ability to remove air and water born pollutants. This paper reviews the current status of production and conversion of microalgae, including the advantages of microalgae biodiesel, high density...

A technical evaluation of a plant for biodiesel production from microalgae was investigated in which a novel configuration of a CPR (closed pond photobioreactor) is proposed. The entire process was simulated by Aspen Plus® and optimized energetically in order to obtain the best profits in...

Pyrolysis characteristics of three species of microalgae (SC (Scenedesmus almeriensis), NG (Nannochloropsis gaditana) and CV (Chlorella vulgaris)) have been studied by TGA–MS (thermogravimetric analysis coupled with mass spectrometry). The thermal behavior of microalgae samples could be...

The effect of different organic solvents, such as methanol, ethanol and 1,4-dioxane, on thermochemical liquefaction characteristics of Spirulina (a kind of high-protein microalgae) was systematically studied. The liquefaction experiments were conducted in a 1000 mL autoclave at different...

This work presents the results of a thorough EROEI (Energy Return on Energy Investment) analysis for biocrude production from microalgae processes. We have investigated different alternatives to maximize the energy recoveries of each process considered, which has been modeled and simulated by...

The Present study investigates the carbon sequestration potential and biodiesel production ability of a microalga isolated from a marble mining site. The microalgal isolates were grown in BG-11 medium supplemented with sodium bicarbonate (NaHCO3) as a carbon source. The growth behavior of the...

In response to energy crisis, global warming and climate changes, microalgae have received a great deal of interest as a biofuel feedstock. However, the development of microalgal biofuels witnesses an obvious and serious dilemma. The reported literature shows that “fuel only” option is not...

Research studies on microalgae have increased in the last decades due to the wide range of applications associated to these photosynthetic microorganisms. Microalgae are an important source of oils and other biomolecules that can be used in the production of biofuels and high-valued products....

Excessive uses of fossil fuels and environmental degradation have forced the scientists to find alternative and clean sources of energy. Biofuels are considered as potential alternatives as they are green in nature and are sustainable energy sources. Biodiesel is one of the most commonly used...
