交通能源期货系列:在一个成熟市场的动力预计生物质利用的燃料
The viability of biomass as transportation fuel depends upon the allocation of limited resources for fuel, power, and products. By focusing on mature markets, this report identifies how biomass is projected to be most economically used in the long term and the implications for greenhouse gas (GHG) emissions and petroleum use. In order to better understand competition for biomass between these markets and the potential for biofuel as a market-scale alternative to petroleum-based fuels, this report presents results of a micro-economic analysis conducted using the Biomass Allocation and Supply Equilibrium (BASE) modeling tool. The findings indicate that biofuels can outcompete biopower for feedstocks in mature markets if research and development targets are met. The BASE tool was developed for this project to analyze the impact of multiple biomass demand areas on mature energy markets. The model includes domestic supply curves for lignocellulosic biomass resources, corn for ethanol and butanol production, soybeans for biodiesel, and algae for diesel. This is one of a series of reports produced as a result of the Transportation Energy Futures (TEF) project, a Department of Energy-sponsored multi-agency project initiated to pinpoint underexplored strategies for abating GHGs and reducing petroleum dependence related to transportation.

海军生物燃料计划署的起源和国防能源的波动性问题
This thesis presents three catalysts for the origins of the Department of the Navy's biofuel initiative: (1) Section 526 of the Energy Independence and Security Act of 2007 effectively ended the Department of Defense s (DoD s) research program into synthetic fuels derived from fossil fuels; (2) the crude oil spot price reached a maximum daily price of $145.16 on July 14, 2008; and (3) the American Recovery and Reinvestment Act of 2009 appropriated over one billion dollars for biomass research and development. Although cost volatility has impacted the DoD s budget, the DoD already has used the Defense Working Capital Fund to make perceived oil prices less volatile to DoD users. Drop-in replaceable biofuels would not remove petroleum price volatility because biofuels act as close substitutes. The governments of other countries reduce cost volatility by managing fuel price risk using futures contracts; opinions differ on whether the DoD should pursue this option. To mitigate cost volatility, the Defense Business Board recommended exploring intragovernmental transfers between the DoD and Department of the Interior on two occasions. Long-term contracts could reduce volatility, but the DoD risks losing competitors in supply.

机会和障碍的大型生物质利用:一个研讨会总结:化学科学与工程领域中的作用
Over the past two years, the federal government has released several reports highlighting the importance of biomass as a potential source of economic growth and energy independence. In January 2011, for example, the Congressional Research Service issued a report titled Agriculture-Based Biofuels: Overview and Emerging Issues that reviewed the evolution of the U.S. biofuels sector and the role that federal policy has played in shaping its development. In August, 2011, the Department of Energy (DOE) released 2011 U.S. Billion-Ton Update: Biomass Supply for a Bioenergy and Bioproducts Industry, which detailed U.S. biomass feedstock potential nationwide. The report examined the nation's capacity to produce a billion dry tons of biomass resources annually for energy uses without impacting other vital U.S. farm and forest products, such as food, feed, and fiber crops. Then in April 2012, the White House Office of Science and Technology Policy issued the National Bioeconomy Blueprint, a large portion of which described the importance of biomass as a source of energy and chemicals for manufacturing.
