“…It has been reported that the refinery plants used in HVO production need to be scaled up to become more competitive in the medium term, 52 and that the role of public policy in this context is essential. 6 One policy currently applied to help develop advanced biofuels is granting decarbonization credits. To adjust these credits with the investment required to scale-up the plants, total investment for HVO production in Brazil was calculated based on the IEA projections for investment range for HVO plants, 48 in each of the scenarios assessed (see Table 5).…”

“…Currently, in Brazil, the biodiesel production is strongly dependent on soybean, which corresponds to around 80% of the raw material used nationally for biodiesel since 2008. 6 Current national legislation demands 13% of biodiesel blended in all commercial diesel; however, in the face of the coronavirus pandemic, the national biodiesel industry has been struggling, which has led to soybean scarcity, increasing prices, and compromising biodiesel production. This resulted in a presidential decree that reduced the mandatory biodiesel fraction in commercial diesel from 13% to 10% in order to control prices.…”

“…This resulted in a presidential decree that reduced the mandatory biodiesel fraction in commercial diesel from 13% to 10% in order to control prices. 7 The most common biofuel in Brazil and South America, for diesel engines, is biodiesel from soybean oil; 6 however, due to its inferior cetane number and calorific value, and its instability with regard to oxidation and storage, 8 biodiesel is not well accepted for use in internal combustion engines. When pure biodiesel is applied to an internal combustion engine, a series of problems can be observed, such as low efficiency atomization, incomplete combustion, problems associated with injection of fuel, and sedimentation in the engine resulting from impurities.…”

Curb CO 2 emissions' is a common expression today and it will be heard even more frequently in the future. Biofuels have attracted attention for many years, and recently this attention has been directed, in particular, to biofuels in heavy-duty vehicles. This sector contributes to a significant quantity of emissions in Brazil. This class of fuels -biodiesel, fatty acid methyl esters (FAMEs) -has an established industry in Brazil. However, the limited capacity for the production of biodiesel, and the limitations imposed by its properties, make it difficult to expand the industry. Thus, hydrotreated vegetable oils (HVOs) have emerged as a more environmental friendly fuel and a potential alternative to cut emissions in the transportation sector. To identify ways to use such fuels in Brazil, this study reviews environmental indicators for diesel, biodiesel, and HVO, and compares then using a composite score. Based on specific emission factors, scenarios for the use of HVO are evaluated in terms of emissions avoided, potential granting of decarbonization credits, and feasibility for investment. The results in one of the scenarios evaluated show that 0.5 decarbonization credits can be granted for each liter of HVO consumed in Brazil. There is room for profitability in all of the scenarios. This work also shows that Brazil has the necessary public policies to foster biofuels on a large scale, and, with blend mandates being reformulated, the country could avoid emissions of over 12.9 million CO 2 tons per year in the transport sector.

“…Public support strategies include financial support for research in the field, price subsidies, blending mandates, and quantitative targets [ 14 , 147 ]. For instance, in Brazil, the National Agency for Petroleum, Natural Gas and Biofuels (ANP) establishes a mandatory biodiesel fraction in commercial diesel, which has gradually increased since 2008 reaching 13% [ 148 , 149 ].…”

Development of Microalgae Biodiesel: Current Status and Perspectives

Microalgae are regarded as a promising source of biodiesel. In contrast with conventional crops currently used to produce commercial biodiesel, microalgae can be cultivated on non-arable land, besides having a higher growth rate and productivity. However, microalgal biodiesel is not yet regarded as economically competitive, compared to fossil fuels and crop-based biodiesel; therefore, it is not commercially produced. This review provides an overall perspective on technologies with the potential to increase efficiency and reduce the general costs of biodiesel production from microalgae. Opportunities and challenges for large-scale production are discussed. We present the current scenario of Brazilian research in the field and show a successful case in the research and development of microalgal biodiesel in open ponds by Petrobras. This publicly held Brazilian corporation has been investing in research in this sector for over a decade.
