“…Optimum production line configuration for 600 liter/day biodiesel production. [45] Methanol cost in the current study is in the higher range of the global price which is expected for low production capacity below 1000 ton/year similar to the biodiesel production facility at Caetes/Brazil. [46] Future perspective A comprehensive technical and economic feasibility study was performed for small and medium scale biodiesel production in Yemen.…”

“…For economically feasible production of microalgal biofuels, the production cost should be comparable to that of other commercialized biofuels, ethanol and biodiesel from corn, sugarcane, oil palm, and soybean oil. The production costs for biofuels from conventional energy crops ranged from 0.21 to 0.99 USD L −1 . In the case of biofuel production from microalgae, 1 USD L −1 was set as the cost to achieve economic feasibility.…”

Microalgae have long been considered as one of most promising feedstocks with better characteristics for biofuels production over conventional energy crops. There have been a wide range of estimations on the feasibility of microalgal biofuels based on various productivity assumptions and data from different scales. The theoretical maximum algal biofuel productivity, however, can be calculated by the amount of solar irradiance and photosynthetic efficiency (PE), assuming other conditions are within the optimal range. Using the actual surface solar irradiance data around the world and PE of algal culture systems, maximum algal biomass and biofuel productivities were calculated, and feasibility of algal biofuel were assessed with the estimation. The results revealed that biofuel production would not easily meet the economic break‐even point and may not be sustainable at a large‐scale with the current algal biotechnology. Substantial reductions in the production cost, improvements in lipid productivity, recycling of resources, and utilization of non‐conventional resources will be necessary for feasible mass production of algal biofuel. Among the emerging technologies, cultivation of microalgae in the ocean shows great potentials to meet the resource requirements and economic feasibility in algal biofuel production by utilizing various marine resources.

“…Studies indicate that the oil feedstock share in the total biodiesel cost stayed between 50 and 90%, increasing in function of raising production scales. [43][44][45][46][47][48] As shown in Figs 3 and 4, the reduction of the soybean oil price in the analyzed period and the considerable share of this feedstock contribute strongly to the evolution observed in the biodiesel total cost.…”

The biodiesel blending mandate was launched at 2005 in Brazil, by a governmental program based mainly on sustainability concerns, especially toward social and environmental aspects. Since 2007, B7, i.e., 7% biodiesel in diesel, in volume terms, has been mandatory, and B10 is the next target. In this context, this paper aims to evaluate the biodiesel program along the ten years from 2005 to 2015 in Brazil, considering the evolution of the estimated costs and the auction prices intending to verify some tendency in a learning curve perspective. A decreasing tendency of the biodiesel production costs and prices was observed, with a reduction of the profit margin in recent years, suggesting a learning trend. The Progress Ratio (PR) of the whole period was 101.7%, but in the 2011–2015, it was estimated at 59.3%. Relevant technology changes in biodiesel production process were not verified, but the increased competitiveness in the market, the gains of scale of plant profiles, and mainly the decrease of soybean oil prices explain this evolution. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd
