Biodiesel Production Technology
7/31/2004
Biodiesel is an alternative fuel for diesel engines that is gaining attention in the United States after reaching a considerable level of success in Europe. Its primary advantages are that it is one of the most renewable fuels currently available and it is also non-toxic and biodegradable. It can also be used directly in most diesel engines without requiring extensive engine modifications. The purpose of this book is to describe and explain the processes and issues involved in producing this new fuel.

Biodiesel Analytical Methods
7/31/2004
Biodiesel is an alternative fuel for diesel engines that is receiving great attention world wide. Although it attracts the most attention because it is renewable, it can be used either pure or in blends with diesel fuel in unmodified diesel engines, and it reduces some exhaust pollutants. It is also attractive because it can be produced easily from common feedstocks. However, the relative simplicity of biodiesel production can disguise the importance of maintaining high quality standards for any fuel supplied to a modern diesel engine. It is essential to the growth of the biodiesel industry that all fuel produced and sold meet these quality standards.

Evaluation of Biodiesel Fuel in an EMD GP38-2 Locomotive
5/30/2004
This report documents results of fuel consumption and exhaust emission tests performed on a 2,000 hp EMD GP38-2 locomotive operating on four different fuels. No operational problems were observed by SwRI on any of the test fuels, and the locomotive engine was able to produce within 1% to 2% of full rated power while operating on the biodiesel blends. Locomotive tests were performed at the SwRI Locomotive Exhaust Emissions Test Center in October, 2000.

Fuel and Fuel Additive Registration Testing for Ethanol-Diesel Blend for O2Diesel, Inc.
2/1/2004
Testing was performed on a heavy-duty diesel engine in support of the Environmental Protection Agency (EPA) requirements for registration of designated fuels and fuel additives as stipulated by sections 211(b) and 211(e) of the Clean Air Act. Emission generation, collection, and analysis of the regulated emissions and speciation of vapor-phase and semi-volatile hydrocarbon compounds were performed on a Detroit Diesel Series 60 engine manufactured in 2002 and meeting the 1998 federal heavy-duty emission standards that applied in 2002.

Business Management for Biodiesel Producers
1/31/2004
The material contained in this book is intended to provide the reader with information about biodiesel in four basic areas: (1) Biodiesel and the liquid fuels industry, (2) Biodiesel business start-up issues, (3) Legal and regulatory issues, and (4) Operational concerns. Information about production of biodiesel and maintaining quality control are covered in separate publicatons.

State-Level Workshops on Ethanol for Transportation
1/31/2004
In 2002/2003, under contract to the National Renewable Energy Laboratory, BBIInternational conducted state-level workshops ethanol in Hawaii, Nevada, Kentucky and California. These four workshops followed over 30 other workshops previous held under the Ethanol Workshop Series program sponsored by the U.S. Department of Energy. Two other workshops were conducted by BBI International during 2003, Oklahoma and Kansas, under contract to the Western Regional Biomass Energy Program.The Ethanol Workshop Series (EWS) was intended to provide a forum for interest groups to gather and discuss what needs to be accomplished to facilitate ethanol production in-state using local biomass resources. In addition, the EWS was to provide a promotional and educational forum for policy makers, community leaders, media and potential stakeholders. It was recognized that to eventually achieve biomass-ethanol production, it was necessary to supportgrain-ethanol production as a bridge.The long-term goal of the Workshops was to facilitate the development of biomass ethanol plants at a state-level. The near-term goal was to provide correct and positive information for education, promotion, production and use of fuel ethanol. The EWS drew from 65 to over 200 attendees and were deemed by the local organizers to have served the objectives set out by the U.S. Department of Energy.

Ethanol Fuel Incentives Applies in the U.S.--Reviewed from California's Perspective
1/31/2004
This report describes measures employed by state governments and by the federal government to advance the production and use of ethanol fuel in the United States. The future of ethanol as an alternative transportation fuel poses a number of increasingly-important issues and decisions for California government, as the state becomes a larger consumer, and potentially a larger producer, of ethanol.

Biomass Power and Conventional Fossil Systems with and without CO2 Sequestration--Comparing the Energy Balance, Greenhouse Gas Emissions and Economics
1/31/2004
Power generation emits significant amounts of greenhouse gases (GHGs), mainly carbon dioxide (CO2). Sequestering CO2 from the power plant flue gas can significantly reduce the GHGs from the power plant itself, but this is not the total picture. CO2 capture and sequestration consumes additional energy, thus lowering the plant's fuel-to-electricity efficiency. To compensate for this, more fossil fuel must be procured and consumed to make up for lost capacity. Taking this into consideration, the global warming potential (GWP), which is a combination of CO2, methane (CH4), and nitrous oxide (N2O) emissions, and energy balance of the system need to be examined using a life cycle approach. This takes into account the upstream processes which remain constant after CO2 sequestration as well as the steps required for additional power generation.
