“…Revisiting algae biofuels 3.1 Algae technical specificities Several studies have been conducted on the technical feasibility of growing algae for biofuel production in the laboratory (Williams and Laurens, 2010;Demirbas and Demirbas, 2010;Tao and Aden, 2009;Chisti, 2007;Brennan and Owende, 2010;Hirano et al, 1997;Ono and Cuello, 2006;Pulz, 2001;Pulz and Gross, 2004;Sheehan et al, 1998;Spolaore et al, 2006;Terry and Raymond, 1985;Ugwu et al, 2008;Delrue et al, 2012;Wijffels and Barbosa, 2010), which have proved absence of the major drawbacks associated with current biofuels. However, several hurdles still need to be overcome in order to scale up the production, while the costs of producing this emerging biofuels are still high compared with other biofuel sources.…”

Purpose -Currently, experimental and theoretical work is being performed to ensure that biofuels from microalgae become a reality. However, there is a considerable number of discussions concerning in which processes should be focussed efforts of research and development. The purpose of this paper is to provide decision support not only to help build guidelines of research to be undertaken, but also to contribute to the design of more adequate policy and funding instruments. The key objective of this study is to determine the prospects of employing microalgae into the production of biofuels within a time scale extending to 2030. Design/methodology/approach -The Delphi method is a qualitative research aiming to support strategic future-oriented action, such as policy making in the areas of science and technology. It is especially appropriate in judgment and long-range forecasting (20-30 years) situations, when expert opinions are often the only source of information available, due to a lack of appropriate historical, economic or technical data. Findings -The Delphi method proved to be a successful research method when expert opinions are the main source of information available, due to a lack of appropriate historical, economic or technical data and the outcomes provided a clear outline of the main issues of microalgae biofuels' market at present and in the future.Research limitations/implications -The outcomes might not represent the majority of the microalgae experts' opinion due to the sample size. Originality/value -The work presented in this paper is especially original. According to the authors' knowledge, this is the first qualitative Delphi study related to algae biofuels.

“…A set of articles can be found in the literature evidencing the technical feasibility of growing algae for biofuel production [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], in which the majority of them demonstrate the absence of the major drawbacks associated with current 1st generation biofuels. For example, the most common drawback pointed out of 1st generation biofuels as being the affect on food prices due to massive arable land use.…”

“…These advantages include: (a) capability of producing oil during all year long and with superior efficiency, therefore the oil productivity of microalgae is greater compared to the most efficient crops; (b) producing in brackish water and on not arable land [41]; not affecting food supply or the use of soil for other purposes [2]; (c) possessing a fast growing potential and several species have 20-50% of oil content by weight of dry biomass [2]; (d) Regarding air quality, production of microalgae biomass can fix carbon dioxide [2]; (e) nutrients for its cultivation (nitrogen and phosphorous, mainly) can be obtained from sewage, therefore there is a possibility to assist the municipal wastewater treatment [19,20]; (f) growing algae do not require the use of herbicides or pesticides [42]; (g) algae can also produce valuable co-products, as proteins and biomass after oil extraction, that can be used as animal feed, medicines or fertilizers [3,10], or fermented to produce ethanol or methane [5]; (h) biochemical composition of algal biomass can be modulated by different growth conditions, so the oil yield can be significantly improved [43]; and (i) Capability of performing the photobiological production of "biohydrogen" [22][23][24][25]44].…”

“…As stated before, algae can also produce valuable co-products, such as proteins, natural colorants, and biomass after oil extraction, that can be used as animal feed, medicines or fertilizers [3,10], or fermented to produce ethanol, methane or other biofuels [5]. Although this possibility is widely reported, just a few studies [46,[51][52][53]55,57] looked with attention to this question and made financial calculations on the feasibility of producing biofuel and co-products together.…”

a b s t r a c tThe 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.
