The challenges to biofuel expansion

9By Elton Alisson

Agência FAPESP – Recent resolutions by several countries, including the United States, to increase utilization of renewable fuels through 2021 – in addition to the general need to increase energy production and distribution worldwide – should boost global expansion of the biofuels industry in the coming years.

However, the sector must overcome myriad challenges to meet the greater global demand for bioenergy. These challenges include increasing cultivation of the agricultural crops that are utilized to generate biofuels without affecting food production; adapting to the impact of global climate change in agriculture; and competing on unequal footing with fossil fuels, which are strongly subsidized by innumerous countries, including Brazil… >>Continue Reading<<

Estimating the Biodiesel Supply Curve

2The CROP Site – The purpose of this post is to derive the biodiesel supply curve from the relationships first presented in the September 25 post.

We begin by reviewing the main results of that earlier post. Figure 1 shows a scatter of monthly biodiesel production and net returns above variable costs for each calendar year between 2010 and 2013. Monthly biodiesel production is estimated by the EIA and monthly biodiesel net production returns above variable costs are based on a model of a representative Iowa biodiesel plant (see the post here).

A best-fit regression line is also shown for each year, with the natural log (ln) of production used as the dependent variable. The data are divided by calendar years because in years when the blenders tax credit is not in place (2010 and 2012) there is little relationship between biodiesel production and returns. Basically, production in these years is “stuck” at the RFS biodiesel mandate regardless of the level of returns.

In the other years (2011 and 2013) market participants expect the credit to expire at the end of a calendar year, so there there is an obvious incentive for blenders to bid up the price of biodiesel in order to increase production and take full advantage of the credit before it expires. In essence, the unusual market circumstances in 2011 and 2013 provide a unique opportunity to identify a biodiesel supply curve even with a seemingly binding RFS mandate in place…>>Continue Reading<<

Brazil world leader in sugarcane and ethanol knowledge and technology

 
Mini 018FAPESP – Brazil is the largest producer of ethanol from sugarcane in the world and occupies the leadership in technology for its production. The advances in technology have meant that its productivity is outstanding and the costs of production much lower than those of its international competitors. This leadership is due to the long work of many years undertaken by researchers in institutions of higher education and research and in private enterprises, which has resulted in a valuable baggage of knowledge and technology on sugarcane and its derivatives and on the process of ethanol manufacture.

Challenges of food production and bioenergy in Brazil

0000026354-Logo 40 anosBy Manoel Teixeira Souza Jr.
Embrapa Agroenergy – In 2050, according to various estimates, our planet will have a population slightly more than nine billion people. The challenge for all of us over the coming decades is to ensure the means for producing food and energy in sufficient quantity and quality to meet the demand from a population with two billion more people than today. Demand this already suffering and will continue to suffer, more changes in its nature than its volume, which results in significant increase of input of water and soil, to name only two of the most used features. These resources need to be sustainable, both economically, as the social and the environmental.

Transgenic eucalyptus yields 20% more than conventional

2Biomassa & Agroenergia – In appearance, the small planting of 2.2 hectares of eucalyptus trees on a farm in the municipality of Angatuba (SP), is nothing unusual. But differences exist and these trees are cells that received the insertion of a gene of another species, Arabidopsis thaliana, a plant model widely used in genetic experiments. With the change, they become capable of producing 20% more wood in relation to Eucalyptus counterparts.
A small forest of eucalyptus growing GM is one of four experimental plantings of this tree made by genetically modified FuturaGene, Continue reading

The use of ethanol as fuel in Brazil will complete a century

0000002639-Agroenergia_baixaEmbrapa Agroenergy – It has long been used fuel produced by microorganisms in Brazil. Ethanol was first used in Otto cycle engines, about 50 years before the launch of Proalcool. Historical records show that in 1925, a 4-cylinder car brand Ford participated in a race of 230 km in the city of Rio de Janeiro, using 70% ethyl alcohol as fuel. Image of this car is immortalized in the book commemorating 80 years of the creation of the National Institute of Technology and is reproduced in Figure 1. Subsequently, the INT was itself made possible the production of anhydrous ethanol for blending with gasoline, allowing editing of Decree 19717 of February 20, 1931, which required importers of gasoline to blend 5% ethanol to fossil fuel.

SGB and Embrapa formalize strategic partnership in research to develop jatropha in Brazil

JatrophaBiomassa & Bioenergia – GBS, Inc. (SG Biofuels) and Embrapa (Brazilian Agricultural Research Corporation) entered into a strategic research agreement to promote the development of jatropha as an alternative source of renewable energy in Brazil. Headquartered in San Diego, USA, GBS is an energy crop company that provides high-performance solutions for the markets of renewable energy, biomass and chemicals. It is a leader in its segment and offers the largest and most diverse library of genetic material of Jatropha in the world. The company has been working on this development for five years, combining platforms breeding and genomics.
