Available in PDF, EPUB and Kindle. Book excerpt: This study develops techno-economic models for assessment of the conversion of biomass to valuable fuel products via fast pyrolysis and bio-oil upgrading. The upgrading process produces a mixture of naphtha-range (gasoline blend stock) and diesel-range (diesel blend stock) products. This study analyzes the economics of two scenarios: onsite hydrogen production by reforming bio-oil, and hydrogen purchase from an outside source. The study results for an nth plant indicate that petroleum fractions in the naphtha distillation range and in the diesel distillation range are produced from corn stover at a product value of $3.09/gal ($0.82/liter) with onsite hydrogen production or $2.11/gal ($0.56/liter) with hydrogen purchase. These values correspond to a $0.83/gal ($0.21/liter) cost to produce the bio-oil. Based on these nth plant numbers, product value for a pioneer hydrogen-producing plant is about $6.55/gal ($1.73/liter) and for a pioneer hydrogen-purchasing plant is about $3.41/gal ($0.92/liter). Sensitivity analysis identifies fuel yield as a key variable for the hydrogen-production scenario. Biomass cost is important for both scenarios. Changing feedstock cost from $50-$100 per short ton changes the price of fuel in the hydrogen production scenario from $2.57-$3.62/gal ($0.68-$0.96/liter).

Available in PDF, EPUB and Kindle. Book excerpt: In the United States, we have come to depend on plentiful and inexpensive energy to support our economy and lifestyles. In recent years, many questions have been raised regarding the sustainability of our current pattern of high consumption of nonrenewable energy and its environmental consequences. Further, because the United States imports about 55 percent of the nation's consumption of crude oil, there are additional concerns about the security of supply. Hence, efforts are being made to find alternatives to our current pathway, including greater energy efficiency and use of energy sources that could lower greenhouse gas (GHG) emissions such as nuclear and renewable sources, including solar, wind, geothermal, and biofuels. The United States has a long history with biofuels and the nation is on a course charted to achieve a substantial increase in biofuels. Renewable Fuel Standard evaluates the economic and environmental consequences of increasing biofuels production as a result of Renewable Fuels Standard, as amended by EISA (RFS2). The report describes biofuels produced in 2010 and those projected to be produced and consumed by 2022, reviews model projections and other estimates of the relative impact on the prices of land, and discusses the potential environmental harm and benefits of biofuels production and the barriers to achieving the RFS2 consumption mandate. Policy makers, investors, leaders in the transportation sector, and others with concerns for the environment, economy, and energy security can rely on the recommendations provided in this report.

Available in PDF, EPUB and Kindle. Book excerpt: Developing the Global Bioeconomy: Technical, Market, and Environmental Lessons from Bioenergy brings together expertise from three IEA-Bioenergy subtasks on pyrolysis, international trade, and biorefineries to review the bioenergy sector and draw useful lessons for the full deployment of the bioeconomy. Despite the vast amount of politically driven strategies, there is little understanding on how current markets will transition towards a global bioeconomy. The question is not only how the bioeconomy can be developed, but also how it can be developed sustainably in terms of economic and environmental concerns. To answer this question, this book’s expert chapter authors seek to identify the types of biorefineries that are expected to be implemented and the types of feedstock that may be used. They also provide historical analysis of the developments of biopower and biofuel markets, integration opportunities into existing supply chains, and the conditions that would need to be created and enhanced to achieve a global biomass trade system that could support a global bioeconomy. As expectations that a future bioeconomy will rely on a series of tradable commodities, this book provides a central accounting of the state of the discussion in a multidisciplinary approach that is ideal for research and academic experts, and analysts in all areas of the bioenergy, biofuels, and bioeconomy sectors, as well as those interested in energy policy and economics. Examines the lessons learned by the bioenergy industry and how they can be applied to the full development of the bioeconomy Explores different transition strategies and how the current fossil based and future bio-based economy are intertwined Reviews the status of current biomass conversion pathways Presents an historical analysis of the developments of biopower and biofuel markets, integration opportunities into existing supply chains, and the conditions that would need to be created and enhanced to achieve a global biomass trade system

Available in PDF, EPUB and Kindle. Book excerpt: Rising concerns about the environmental impacts of fossil transportation fuels have motivated the development of alternative sources of energy that are renewable and environment-friendly. Biomass-derived liquid hydrocarbon fuels, offer an immediate "drop-in" alternative for displacing petroleum-derived transportation fuels, owing to their ability to use existing infrastructure. However, biomass, as an energy source is disadvantaged in terms of carbon and energy content. The Billion Ton Report 2016 predicts 1.3 billion tonnes of harvestable biomass in the U.S. by 2030. The carbon and energy content of this amount of biomass is not sufficient to support the demands of the U.S. transportation sector alone. Furthermore, traditional bioenergy systems like cellulosic fermentations to ethanol (CE), lose 1/3rd of the biomass carbon as CO2 and fail to utilize lignin ( ~40% of biomass energy) for fuel production. This calls for biomass conversion technologies that retain most of the biomass carbon and efficiently capture the inherent biomass energy in the produced liquid fuels. This can be achieved via fast pyrolysis that can convert all biomass (including lignin) to predominantly liquid bio-oil. However, this bio-oil is unstable, due to the presence of reactive functional groups. This fact combined with its low energy content makes it unfit as a fuel or a stable intermediate. In this regard, electrocatalytic hydrogenation (ECH) can harness renewable electricity from solar/wind farms and sufficiently hydrogenate the pyrolysis bio-oil to generate a stable intermediate that can be transported over long distances. Additionally, ECH employs mild conditions that allows it to be implemented at a local small-scale facility. This offers a key advantage in a bioenergy system, where transporting the low bulk density biomass can incur large transportation costs. The denser ECH-ed bio-oil can hence be transported at lower costs to conventional hydroprocessing facilities to produce a gasoline/diesel range fuel.In this study, a bioenergy system (Py-ECH) was developed that combines fast pyrolysis with ECH at decentralized depots, followed by hydroprocessing at a central refinery. The mass, carbon and energy flux through the system and the fuel yields were estimated. The fuel yields for the Py-ECH system were found to be better than CE in terms of energy, mass and carbon.To evaluate the economics of Py-ECH, a full techno-economic analysis was conducted using a discounted cash flow rate of return (DCFROR) approach and nth plant assumptions. The minimum fuel selling price (MFSP) of the Py-ECH fuel was found to be $ 3.62/gge (in 2018 $) compared to $ 3.70/gge (in 2018$) for CE. Through sensitivity analyses, key cost-contributing parameters were identified, and a pathway was charted for MFSP reduction to

This book was released on 2015 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report was developed as part of the U.S. Department of Energy's Bioenergy Technologies Office's efforts to enable the development of technologies for the production of infrastructurecompatible, cost-competitive liquid hydrocarbon fuels from biomass. Specifically, this report details two conceptual designs based on projected product yields and quality improvements via catalyst development and process integration. It is expected that these research improvements will be made within the 2022 timeframe. The two conversion pathways detailed are (1) in situ and (2) ex situ upgrading of vapors produced from the fast pyrolysis of biomass. While the base case conceptual designs and underlying assumptions outline performance metrics for feasibility, it should be noted that these are only two of many other possibilities in this area of research. Other promising process design options emerging from the research will be considered for future techno-economic analysis.

Download or read book Conceptual Process Design and Techno economic Assessment of Ex Situ Catalytic Fast Pyrolysis of Biomass written by and published by . This book was released on 2015 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ex situ catalytic fast pyrolysis of biomass is a promising route for the production of fungible liquid biofuels. There is significant ongoing research on the design and development of catalysts for this process. However, there are a limited number of studies investigating process configurations and their effects on biorefinery economics. Herein we present a conceptual process design with techno-economic assessment; it includes the production of upgraded bio-oil via fixed bed ex situ catalytic fast pyrolysis followed by final hydroprocessing to hydrocarbon fuel blendstocks. This study builds upon previous work using fluidized bed systems, as detailed in a recent design report led by the National Renewable Energy Laboratory (NREL/TP-5100-62455); overall yields are assumed to be similar, and are based on enabling future feasibility. Assuming similar yields provides a basis for easy comparison and for studying the impacts of areas of focus in this study, namely, fixed bed reactor configurations and their catalyst development requirements, and the impacts of an inline hot gas filter. A comparison with the fluidized bed system shows that there is potential for higher capital costs and lower catalyst costs in the fixed bed system, leading to comparable overall costs. The key catalyst requirement is to enable the effective transformation of highly oxygenated biomass into hydrocarbons products with properties suitable for blending into current fuels. Potential catalyst materials are discussed, along with their suitability for deoxygenation, hydrogenation and C-C coupling chemistry. This chemistry is necessary during pyrolysis vapor upgrading for improved bio-oil quality, which enables efficient downstream hydroprocessing; C-C coupling helps increase the proportion of diesel/jet fuel range product. One potential benefit of fixed bed upgrading over fluidized bed upgrading is catalyst flexibility, providing greater control over chemistry and product composition. Since this study is based on future projections, the impacts of uncertainties in the underlying assumptions are quantified via sensitivity analysis. As a result, this analysis indicates that catalyst researchers should prioritize by: carbon efficiency> catalyst cost> catalyst lifetime, after initially testing for basic operational feasibility.
