Decentralized biomass processing facilities, known as depots, may be necessary to achieve feedstock cost, quantity, and quality required grow the future U.S. bioeconomy. In this paper, we assess three distinct depot configurations for technical difference economic performance. The designs were chosen compare contrast a suite of capabilities that could perform ranging from conventional pelleting sophisticated pretreatment technologies. Our analyses indicate costs are likely range ∼US$30 US$63...
Abstract Pioneer cellulosic biorefineries across the United States rely on a conventional feedstock supply system based one‐year contracts with local growers, who harvest, locally store, and deliver in low‐density format to conversion facility. While is designed for high biomass yield areas, pilot scale operations have experienced shortages price volatilities due reduced harvests competition from other industries. Regional dependency inability actively manage stability quality, provide...
Abstract The 2011 US Billion‐Ton Update estimates that by 2030 there will be enough agricultural and forest resources to sustainably provide at least one billion dry tons of biomass annually, displace approximately 30% the country's current petroleum consumption. A portion these are inaccessible cost targets with conventional feedstock supply systems because their remoteness or low yields. Reliable analyses projections biofuels production depend on assumptions about system biorefinery...
Incorporation of dedicated herbaceous energy crops into row crop landscapes is a promising means to supply an expanding biofuel industry while benefiting soil and water quality increasing biodiversity. Despite these positive traits, remain largely unaccepted due concerns over their practicality cost implementation. This paper presents case study for Hardin County, Iowa, demonstrate how subfield decision making can be used target candidate areas conversion production. Estimates variability in...
To meet Energy Independence and Security Act (EISA) cellulosic biofuel mandates, the United States will require an annual domestic supply of about 242 million Mg biomass by 2022. improve feedstock logistics lignocellulosic biofuels in order to access available resources from areas with varying yields, commodity systems have been proposed designed deliver quality-controlled feedstocks at preprocessing “depots”. Preprocessing depots densify stabilize prior long-distance transport delivery...
This work shows preliminary results from techno-economic analysis and life cycle greenhouse gas of the conversion seven (7) biomass feedstocks to produce liquid transportation fuels via fast pyrolysis upgrading hydrodeoxygenation. The consists five (5) pure feeds (pine, tulip poplar, hybrid switchgrass, corn stover) two blends. Blend 1 equal weights pine, blend 2 is 67% pine 33% poplar. Upgraded oil product yield one most significant parameters affecting process economics, a function both...
Engineering feedstock supply systems that deliver affordable, high-quality biomass remains a challenge for the emerging bioenergy industry. Cellulosic is geographically distributed and has diverse physical chemical properties. Because of this cellulosic resources to biorefineries require integration broad set engineered unit operations. These operations include harvest collection, storage, preprocessing, transportation processes. Design decisions each system operation impact engineering...
Abstract With growing demand for internationally traded biomass, the logistic operations required to economically move biomass from field or forest end‐ users have become increasingly complex. To design cost effective and sustainable feedstock supply chains, it is important understand economics, energy greenhouse gas ( GHG ) emissions, their interdependencies, related uncertainties of process international chains. This paper presents an approach assessing lignocellulosic systems at...
This paper analyzes the rural Chinese biomass supply system and models chain operations according to U.S. concepts of logistical unit operations: harvest collection, storage, transportation, preprocessing, handling queuing. In this paper, we quantify logistics cost corn stover sweet sorghum in China under different scenarios. We analyze three scenarios from northeast stalks Inner Mongolia China. The case study estimates that stalk be $52.95/dry metric ton $52.64/dry ton, respectively, for...
<abstract> <bold>Abstract.</bold> Developing uniformly formatted, densified feedstock from both forest and agricultural based biomass is of interest to decrease cost increase quality through influencing storage, transportation, handling characteristics. Raw biomass, by nature, highly variable. Densification eliminates variability achieving consistent size, shape, bulk unit density, durability. A variety densification systems such as (1) pellet mill, (2) cuber, (3) screw extruder, (4)...
