The need to develop innovative technologies that could replace fossil fuels and, consequently contribute to the reduction in emissions of greenhouse gases is now clear. In this circumstance, algal biofuels are generating considerable interest around the world. The purpose of this study is to provide an integrated assessment of microalgae potential as a source of biofuels, while comparing its costs with that from other emerging biofuel technologies. This article emphasizes the importance of emerging United States and European Union energy policies that will encourage the development of innovative, and sustainable technologies in their respective regions. An ample review of the scientific literature was carried out, contributing to the analysis of cost, economic and technical indicators. The results obtained allowed the detection of important gaps of information that need to be filled, in order to guide future investment decisions concerning this rising technology.
