Biomethane from Dairy Waste: A Sourcebook for the Production and Use of Renewable Natural Gas in California
7/1/2005
This report examines the feasibility of producing biomethane from dairy manure. We investigated a number of possible technologies for producing renewable forms of energy and fuel from dairy wastes as well as applications and markets for these products. Although some of the applications proved to be technically or economically infeasible at this time, we believe that the information gathered could prove useful for other investigators or future studies. With this in mind, we designed this sourcebook for readers and investigators interested in exploring alternate uses of biogas created from dairy wastes.

Clean Cities Alternative Fuel Price Report - March 28, 2005
3/28/2005
This is the fourteenth issue of the Clean Cities Alternative Fuel Price Report, a quarterly newsletter keeping you up to date on the prices of alternative fuels in the U.S. and their relation to gasoline and diesel prices. This issue discusses prices that were gathered from Clean Cities coordinators and stakeholders between March 8 and March 22, 2005, with comparisons to the prices in the previous Price Report, which were collected in November, 2004. The changes in prices from one reporting period to the next can be attributed not only to price volatility, but also to an inconsistent set of respondents. Thus, differences from one report to the next should not be assumed to reflect trends.

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.

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.

In 2002/2003, under contract to NREL, BBI International conducted state-level ethanol workshops in Hawaii, Nevada, Kentucky, and California. These four workshops followed over 30 other workshops previously held under the Ethanol Workshop Series program sponsored by DOE. Two other workshops were conducted by BBI during 2003 in OK and KS under contract to the Western Regional Biomass Energy Program.

Production of Butyric Acid and Butanol from Biomass
1/1/2004
Butanol was used to replace gasoline gallon for gallon in a 10,000 mile trip across the U.S. without the need to highy modify a 1992 Buick. Butanol can now be made for less than ethanol and yields more BTUs from the same corn, making the plow-to-tire equation positive. Butanol when substituted for gasoline gives better gas mileage and does not pollute the atmosphere.

The Economic Costs of Fuel Economy Standards Versus a Gasoline Tax
12/1/2003
In recent years, there has been renewed interest in the Congress in policies that would reduce gasoline consumption in the United States. That interest has been motivated primarily by concerns about the nation's energy security and about the risk that carbon emissions, 20 percent of which come from gasoline consumption, may affect the Earth's climate. This Congressional Budget Office (CBO) study—prepared at the request of the Senate Committee on Environment and Public Works—compares the economic costs of two methods for reducing gasoline consumption: raising the corporate average fuel economy (CAFE) standards for passenger vehicles and increasing the federal tax on gasoline. In analyzing CAFE standards, the study also estimates the potential cost savings from allowing automakers to trade fuel economy credits with one another as a way of complying.
The study breaks down the costs that each of the alternative policies would impose on both producers and consumers. Further, it discusses the prospects for CAFE standards to improve social welfare given that the existing gasoline tax also provides consumers an incentive to buy more-fuel-efficient vehicles. In keeping with CBO's mandate to provide objective, impartial analysis, this study makes no recommendations.
