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<<

Microalgae for biodiesel production and other applications: A review

4Science Direct – (Summary) –  Sustainable production of renewable energy is being hotly debated globally since it is increasingly understood that first generation biofuels, primarily produced from food crops and mostly oil seeds are limited in their ability to achieve targets for biofuel production, climate change mitigation and economic growth. These concerns have increased the interest in developing second generation biofuels produced from non-food feedstocks such as microalgae, which potentially offer greatest opportunities in the longer term. This paper reviews the current status of microalgae use for biodiesel production, including their cultivation, harvesting, and processing. The microalgae species most used for biodiesel production are presented and their main advantages described in comparison with other available biodiesel feedstocks. The various aspects associated with the design of microalgae production units are described, giving an overview of the current state of development of algae cultivation systems (photo-bioreactors and open ponds). Other potential applications and products from microalgae are also presented such as for biological sequestration of CO2, wastewater treatment, in human health, as food additive, and for aquaculture…>>Continue reading<<

The local impacts of oil palm expansion in Malasya

BiodieslThis study is part of a broader research process assessing the local economic, social and environmental impacts from feedstock expansion for the growing biofuel sector. Nonetheless, in the Malaysian context, biofuel production volumes are negligible despite government interest in romoting sector expansion.
Since Malaysia is the second largest palm oil producer in the world, palm oil is slated to become the primary feedstock for biofuel production in the country. Since palm oil consistently outperforms all other substitute vegetable oils on price, it is also becoming an important feedstock globally. While a rapidly growing global biofuel sector could develop into an important new market outlet for Malaysia, it does carry a number of risks. This paper aims to reflect on these risks by exploring the local social and land-use impacts of oil palm in the Beluran District of Sabah State. This is based on household surveys to discover the perception of impacts among relevant local stakeholder groups, and remote-sensing analysis. While the impacts of oil palm in the study site cannot be attributed to the biodiesel industry per se, lessons learnt will be directly applicable to the biodiesel sector in Malaysia, and relevant for the whole Southeast Asia region.

Brazilian soybean biodiesel emits 70% less greenhouse gases than fossil diesel

BiodieslBiomassa & Bioenergia – The Brazilian biodiesel produced from soybeans reduces emissions by 70%, at least compared to fossil diesel, when consumed within the country. If delivered for consumption in Europe, emits between 65% and 68% less greenhouse gases (GHG).
The conclusion of a new study commissioned by the Brazilian Association of Vegetable Oil Industries (Abiove), in partnership with the Association of Corn and Soybean Producers of Mato Grosso (APROSOJA / MT) and Brazilian Biodiesel Union and biokerosene (UBRABIO ). The survey was conducted by Delta CO2, a company incubated by EsalqTec, the College of Agriculture Luiz de Queiroz (Esalq / USP).

Biodiesel production in Brazil reached 2.7 billion liters

Fapespe_eBiomassa & Bioenergia – Biodiesel production in the country reached 2.718 billion liters in 2012. The monthly average was 181 million liters. The total represents an increase of almost 2% compared to 2011 production, which was 2.672 billion liters. With this performance, according to the Brazilian Association of Vegetable Oil Industries (Abiove), fuel production in Brazil reached a volume history, being the highest in the last eight years. It should be emphasized that the production of the product in 2005 reached only 736,000 liters.

Embrapa research the bottlenecks of biodiesel production from palm oil

Pailm oleoEmbrapa Agroenergy – Dendê has been considered as a promising raw material for biodiesel production for its high oil productivity and, the fact that has a well established productive system. However, some characteristics of the “palm oil” still require the addition of other oils and fats on the processing procedures to obtain biofuel.
According Dra Itânia Soares, researcher from Embrapa Agroenergy, the acidity, the main inconvenience of the palm oil, fluctuate depending of several factors, being around 5%, while of the soy oil is around 0.5%. The use of oleaginous acids raw materials in the biodiesel production entails to add further steps to the process, which increases the production costs. Using only acid oil, it is common to do primarily the esterification of free fatty acids and then the transesterelization
Embrapa Agroenergy has been testing differents ways to reduce these steps, optimizing the production process and reducing the production cost of fuel. These researches will have increasing from 2013, when the Center and a network of partners begins executing the research project called “Dendepalm” – Strategies genomic and adding value to the supply chain of palm oil – with funding from the “Financier of Studies and Projects” – FINEP.
The challenge extends beyond the biodiesel production, since the final product must attend the quality parameters which is established by the National Agency of Petroleum, Natural Gas and Biofuel (ANP). The purification of Biodiesel directly impacts on the quality parameters of the fuel, for example, the water content, in the laboratory level, task that requires attention, ressallta Dra Dra. Itânia.
It is necessary to be attentive to the impact that the addition of biodiesel from palm on petroleum diesel may cause in the final results of the physicochemical analyzes. That is why, one Center’s objective is also study the methods of controlling product quality. “We are working to optimize the biodiesel production process in a 5 liter reactor to develop a methodology for analyzing, in partnership with ANP,” she adds.
