美国南部的桉树种植园为可再生生物能源提供了可行的原料。模拟了桉树生物质向生物能源设施的交付成本，以了解关键变量如何影响生物质交付成本。在财务分析方面，比较了两种投资情景下16.8、22.4和28.0 Mg ha(-1) y（-1，干重基础）的三种产量，评价了生产力和土地投资对项目财务指标的影响。生物质的交付成本被模拟为每交付毫克55.1美元至66.1美元（从种植园到生物精炼厂的货运距离为48.3公里），这取决于6% IRK的现场生产力（不考虑土地投资）。当分析中包括土地投资时，根据6% IRR的现场生产力，交付的生物质成本增加到每交付毫克65.0美元至79.4美元。如果生物质转化成本低于66毫克（-1），转化为纤维素乙醇可能是有希望的。这些交付的成本和投资分析表明，桉树种植园是美国南部生物能源生产的潜在生物质来源(C) 2010 Elsevier Ltd.。版权所有。
Eucalyptus plantations in the Southern United States offer a viable feedstock for renewable bioenergy. Delivered cost of eucalypt biomass to a bioenergy facility was simulated in order to understand how key variables affect biomass delivered cost. Three production rates (16.8, 22.4 and 28.0 Mg ha(-1) y(-1), dry weight basis) in two investment scenarios were compared in terms of financial analysis, to evaluate the effect of productivity and land investment on the financial indicators of the project. Delivered cost of biomass was simulated to range from $55.1 to $66.1 per delivered Mg (with freight distance of 48.3 km from plantation to biorefinery) depending on site productivity (without considering land investment) at 6% IRK When land investment was included in the analysis, delivered biomass cost increased to range from $65.0 to $79.4 per delivered Mg depending on site productivity at 6% IRR. Conversion into cellulosic ethanol might be promising with biomass delivered cost lower than $66 Mg(-1). These delivered costs and investment analysis show that Eucalyptus plantations are a potential biomass source for bioenergy production for Southern U.S. (C) 2010 Elsevier Ltd. All rights reserved.
