Global Production of Second Generation Biofuels: Trends and Influences
GLOBAL PRODUCTION OF SECOND GENERATION BIOFUELS: TRENDS AND INFLUENCES January 2017 Que Nguyen and Jim Bowyer, Ph. D Jeff Howe, Ph. D Steve Bratkovich, Ph. D Harry Groot Ed Pepke, Ph. D. Kathryn Fernholz DOVETAIL PARTNERS, INC. Global Production of Second Generation Biofuels: Trends and Influences Executive Summary For more than a century, fossil fuels have been the primary source of a wide array of products including fuels, lubricants, chemicals, waxes, pharmaceuticals and asphalt. In recent decades, questions about the impacts of fossil fuel reliance have led to research into alternative feedstocks for the sustainable production of those products, and liquid fuels in particular. A key objective has been to use feedstocks from renewable sources to produce biofuels that can be blended with petroleum-based fuels, combusted in existing internal combustion or flexible fuel engines, and distributed through existing infrastructure. Given that electricity can power short-distance vehicle travel, particular attention has been directed toward bio-derived jet fuel and fuels used in long distance transport. This report summarizes the growth of second-generation biofuel facilities since Dovetail’s 2009 report1 and some of the policies that drive that growth. It also briefly discusses biofuel mandates and second-generation biorefinery development in various world regions. Second generation biorefineries are operating in all regions of the world (Figure 1), bringing far more favorable energy balances to biofuels production than have been previously realized. Substantial displacement of a significant portion of fossil-based liquid fuels has been demonstrated to be a realistic possibility. However, in the face of low petroleum prices, continuing policy support and investment in research and development will be needed to allow biofuels to reach their full potential. -

ABSTRACT Technology for creating also applying biodiesel has been recognized for more than 50 years. Microalgae are a various type of prokaryotic as well as eukaryotic photosynthetic microorganisms that grow rapidly due to their simple structure. Biodiesel is considered as a renewable fuel because it can be obtained from the transformation of vegetable oils, cooking greases or animal fats. Microalgae are sunlight-driven cell factories that convert carbon dioxide to potential biofuels, foods, nourish also high-value bioactives. In addition, these photosynthetic microorganisms are beneficial in bioremediation applications nitrogen fixing biofertilizers. This article focuses on microalgae as a potential source -

However, large-scale biorefineries are not yet cost-competitive with their fossil-fuel counterparts, and it is important to identify biorefinery concepts with high economic performance. For evaluating early-stage biorefinery concepts, one needs to consider not only the technical performance and process costs but also the economic performance of the full supply chain and the impacts on feedstock and product markets. This article presents and demonstrates a conceptual interdisciplinary framework that can constitute the basis for evaluations of the full supply-chain performance of biorefinery concepts. This framework considers the competition for biomass across sectors, assumes exogenous end-use product demand, and incorporates various geographical and technical constraints. -
Biochars and Their Use As Transesterification Catalysts for Biodiesel Production
catalysts Review Biochars and Their Use as Transesterification Catalysts for Biodiesel Production: A Short Review John Vakros Department of Chemistry, University of Patras, GR 26504 Patras, Greece; [email protected]; Tel.: +30-26-1099-7143 Received: 16 October 2018; Accepted: 14 November 2018; Published: 20 November 2018 Abstract: Biodiesel can be a significant alternative for diesel. Usually, it is produced through transesterification with a base catalyst. Using heterogeneous catalysts for transesterification, the process can be more efficient. Among the possible catalysts that can be used, biochars combine high performance for transesterification and valorization of waste biomass. Biochars are cheap materials, and are easy to activate through chemical treatment with acid or base solutions. In this short review, the application of biochar as solid heterogeneous catalysts for transesterification of lipids to produce biodiesel is discussed. Keywords: biodiesel; biochar; acid modification; base modification; transesterification; pseudocatalytic transesterification 1. Introduction Two great challenges that people are called to face in our time is to meet the increasing demand for energy and to reduce the wastes released in the environment. The energy challenge is approached with CO2 neutral fuels like biofuels. Among them, biodiesel has significant advantages and it is preferable for using in existing engines and transport infrastructures. Biodiesel is usually produced through transesterification/esterification of lipids [1]. This process requires the presence of a catalyst. On the other hand, biomass is a class of solid wastes with interesting properties. Biomass can be used directly as fuel, or through gasification or pyrolysis, and produce valuable products. What is more attractive is that the by-product of the pyrolysis process is a carbon rich solid called biochar. -

Production of biodiesel from sunflower oil and ethanol by base catalysed transesterification Production of biodiesel from sunflower oil and ethanol by base catalyzed transesterification MSc Thesis Alejandro Sales Department of Chemical Engineering Royal Institute of Technology (KTH) Stockholm, Sweden June 2011 Production of biodiesel from sunflower oil and ethanol by base catalysed transesterification Production of biodiesel from sunflower oil and ethanol by base catalyzed transesterification MSc Thesis Alejandro Sales Supervisor Rolando Zanzi Vigouroux Department of Chemical Engineering Royal Institute of Technology (KTH) Stockholm, Sweden Examiner Joaquín Martínez Department of Chemical Engineering Royal Institute of Technology (KTH) Stockholm, Sweden June 2011 Abstract Biodiesel is an attractive alternative fuel for diesel engines.The feedstock for biodiesel production is usually vegetable oil, pure oil or waste cooking oil, or animal fats The most common way today to produce biodiesel is by transesterification of the oils with an alcohol in the presence of an alkaline catalyst. It is a low temperature and low‐pressure reaction. It yields high conversion (96%‐98%) with minimal side reactions and short reaction time. It is a direct conversion to biodiesel with no intermediate compounds. This work provides an overview concerning biodiesel production. Likewise, this work focuses on the commercial production of biodiesel. The Valdescorriel Biodiesel plant, located in Zamora (Spain), is taken like model of reference to study the profitability and economics of a biodiesel plant. The Valdescorriel Biodiesel plant has a nominal production capacity of 20000 biodiesel tons per year. The initial investment for the biodiesel plant construction is the 4.5 millions €. The benefits are 2 million €/year. -

Government support for the development of biofuel production is a relevant part of the system of budget regulation of agricultural production in the Russian Federation. Currently, there is no sound financing method for mechanisms of state regulation of biofuel production which impedes impartial allocation of funds and makes this procedure non- transparent and not motivated enough. In view of this situation, a mathematical economic model was developed that allows one to calculate the optimum level of government support for every type of biofuel considering main areas of state support. We propose to consider three scenarios for the determination of the optimum level of public funding. The first one allows for optimization of the level of government support considering sizes of agricultural production for the i-th crop to provide farms of the region. The second scenario suggests the determination of the maximum profit from the biofuel production through increased agriculturally used areas. Finally, the third one considers calculation of the minimum expenses of achieving the volume of production that provides the farm with raw materials. -
Algae's Potential As a Transportation Biofuel
Algae’s Potential as a Transportation Biofuel Kelsi Bracmort Specialist in Agricultural Conservation and Natural Resources Policy April 1, 2013 Congressional Research Service 7-5700 www.crs.gov R42122 CRS Report for Congress Prepared for Members and Committees of Congress Algae’s Potential as a Transportation Biofuel Summary Congress continues to debate the federal role in biofuel research, biofuel tax incentives, and renewable fuel mandates. The debate touches on topics such as fuel imports and security, job creation, and environmental benefits, and is particularly significant for advanced biofuels, such as those produced by algae. Congress established the Renewable Fuel Standard (RFS2)—a mandate requiring that the national fuel supply contain a minimum amount of fuel produced from renewable biomass. The RFS2 is essentially composed of two biofuel mandates—one for unspecified biofuel, which is being met with corn-starch ethanol, and one for advanced biofuels (or non-corn starch ethanol), which may not be met in coming years. Within the advanced biofuels category, the RFS2 requirements for the cellulosic biofuels subcategory (e.g., ethanol from switchgrass) have not been met for the last few years, which could cause alarm, as this subcategory is slated to ramp up from roughly 3% of the standard in 2012 to roughly 44% of the standard in 2022. Limited cellulosic biofuels production has occurred to date. As a result, as allowed under the RFS2, the Environmental Protection Agency (EPA) has lowered the required cellulosic biofuels volume for 2010, 2011, and 2012 and has proposed to do the same for 2013. Currently, algae-based biofuel qualifies as an advanced biofuel under the RFS2, but not as a cellulosic biofuel. -

Lantmännen Agroetanol, Sweden Bioenergy Stringent CO reduction criteria lead to business Success Stories 2 success IEA Bioenergy: 02 2018 Year of implementation: 2005, updated 2015 Location: Norrköping, Sweden Technology: Ethanol biorefinery Location of the ethanol plant close to biomass-based CHP ensures deliveries of renewable electricity and process heat. Principle feedstocks: Wheat and other grains, as well as starch-rich residues from the food industry Products/markets: Fuel ethanol and co-products in the form of protein-rich feed. A further co-product here is the (biobased) carbon dioxide that is captured and sold as industrial raw material to customers in the food processing and packaging industry. Technology Readiness TRL 9 – actual system proven in operational environment Level (TRL): DESCRIPTION Lantmännen is a Swedish agricultural cooperative owned by 25,000 Swedish farmers, providing food, feed and fuel nationally and internationally. Since 2001, Lantmännen has produced fuel ethanol at a facility in Norrköping in South-Eastern Sweden based on wheat and other grains as well as residues from the food industry. The plant was initiated to develop new markets for agricultural products. Thanks to efficient processes, the use of renewable process energy from adjacent biomass-fueled CHP and important co-products in the form of protein-rich feed and biogas, the fuel ethanol produced reduces GHG emissions by more than 90 % compared to fossil fuels. From 2015, Lantmännen is also marketing a renewable ethanol fuel for diesel engines called Agro Cleanpower 95, which reduces GHG emissions by up to 90% compared to fossil diesel. A noteworthy co-product here is the (biobased) CO2 sold as industrial raw material to customers in the food processing and packaging industry, i.e.
