USDA recognized that different regions of the country have a comparative advantage to the type of feedstocks that can be produced and utilized in biofuel production.  By leveraging the availability of these regional resources, diversification of biofuel production will be a national solution to reducing the Nation’s dependence on oil, much of which is imported.

 

These regions were determined based upon the prevalence of potential crop and woody biomass feedstocks adapted to different ecological regions of the county, their yields, and current producer interest.  USDA estimated 4 the following regional biofuel contributions to the RFS2 advanced biofuel goal of at least 21 billion gallons a year by 2022:

 

Southeast: 49.8%

Northeast :               2.0%

Central-Eastern: 43.3%

Northwest:  4.6%

Western:              < 0.3%,

assumed 0 for crop biomass, though there is opportunity for algae and woody biomass

 

 

(1)             RFS2 basis - higher density fuels receive higher weighting relative to ethanol. Biodiesel weight is 1.5

(2)                 Feedstocks: Perennial grasses, soyoil, energy cane, biomass (sweet) sorghum, logging residues

(3)             Feedstocks: Perennial grasses, canola, soyoil, biomass (sweet) sorghum, corn stover, logging residues

(4)             Feedstocks: Perennial grasses, soyoil, biomass (sweet) sorghum, corn stover, logging residues

(5)             Feedstocks: C anola,straw, logging residues

(6)             Feedstocks: Biomass (sweet) sorghum, logging residues

 

 

 

 

This section of the report lays out the availability and regional distribution of the resources needed to produce the biofuels to reach the RFS2 target of 36 bg of renewable biofuels per year. In addition, it presents a path to the regional diversification of advanced biofuels, benefiting multiple local communities across the country.  This information should assist the government in pinpointing potential barriers and bottlenecks to investment and assist the industry in developing commercially viable enterprises that will benefit both the rural economy and U.S. consumers.

 

Assuming an average biorefinery size of 40 million gallons per year, USDA estimates it meeting the RFS2 advanced biofuels goals will mean building of 527 biorefineries, at a cost of $168 billion.5   While we expect the market to react to this need, biorefineries will need to be constructed in a timely manner, while accounting for transportation needs for feedstocks and fuel distribution.

美国农业部认识到，在能够生产出来、并用于生物燃料生产的原料类型方面，美国的不同地区拥有着比较优势。通过发挥这些地区资源的可用性，我们就能将生物燃料生产的多元化作为一种全国性的解决方案，以减少我国对石油的依赖性——大部分石油都是进口的。

在划分这些地区时，我们采用的依据，是适应美国不同生态区域的、具有潜力的农作物原料与木质生物质原料的普遍程度，以及它们的产量和生产商当前的重视程度。美国农业部估计，对于可再生燃料标准第二阶段规定的、到2022年使先进生物燃料至少达到210亿加仑的这一目标，各地区能够贡献的生物燃料比例如下：

         东南：49.8％

         东北：2.0％

         中部－东部：43.3％

         西北：4.6％

         西部：不足0.3％

假定该地区的农作物生物质产量为0，不过该地区尚有提供藻类和木质生物质的机会。

   

 

（1）可再生燃料标准第二阶段规定的基准容积——相对于乙醇，密度更高的燃料得到更高的权数。生物柴油的权数是1.5。

（2）原料：多年生禾草、豆油、能源甘蔗、生物质高粱（甜高粱）、伐木残留物。

（3）原料：多年生禾草、油菜籽、豆油、生物质高粱（甜高粱）、玉米秸秆、伐木残留物。

（4）原料：多年生禾草、豆油、生物质高粱（甜高粱）、玉米秸秆、伐木残留物。

（5）原料：油菜籽、麦秸、伐木残留物。

（6）原料：生物质高粱（甜高粱）、伐木残留物。

 

 

可再生燃料标准第二阶段提出了达到每年使用360亿加仑可再生生物燃料的目标。对于生产这些生物燃料所必需的资源，它们的可用性以及它们的地区分布情况将在本报告的这一部分中列出。此外，这一部分还将提出先进生物燃料地区多元化的一种途径，它将使全国各地许多地方社区受益。这些信息将有助于政府辨识出投资潜在的障碍和瓶颈，并帮助产业部门发展商业上具有存续能力的实业，以使美国的乡村经济和消费者双方都能受益。

假定每家生物精炼厂的年均生产规模是4,000万加仑燃料，那么美国农业部估计，为达到可再生燃料标准第二阶段规定的先进生物燃料目标，就需要建设527家生物精炼厂，成本为1,680亿美元⁵。一方面我们期望市场对这一需求做出反应的同时，另一方面生物精炼厂也需要及时建成，同时还要满足原料及燃料分配对交通运输方面的需求。
