Norcal Prototype LNG Truck Fleet: Final Data Report
2/1/2005
This final data report provides detailed data and analyses related to the report Norcal Prototype LNG Truck Fleet: Final Results, published in July of 2004. It should be used in conjunction with the descriptions, analysis, and conclusions presented in the above-referenced final report to give a complete picture of the evaluation. The detailed data and analyses are divided into four sections:
- Vehicle Systems Descriptions: This section lists the trucks involved in the Norcal evaluation and gives detailed descriptions of the equipment included in the LNG trucks.
- Vehicle Use by Study Group: This section provides a detailed summary of truck use for each of the three truck study groups (LNG, new diesel, and old diesel); these detailed data support the data in the final report, Figure 10 (page 13).
- Fuel Consumption and Fuel Economy: This section provides monthly summaries of fuel consumption and fuel economy by truck and by group for each of the three truck study groups (LNG, new diesel, and old diesel).
- Maintenance Summary: This section provides monthly summaries of maintenance costs by truck and by group for each of two study groups (LNG and new diesel); maintenance costs were not studied for the old diesel trucks.

Peaking of World Oil Production: Impacts, Mitigation, and Risk Management
2/1/2005
The peaking of world oil production presents the U.S. and the world with an unprecedented risk management problem. As peaking is approached, liquid fuel prices and price volatility will increase dramatically, and without timely mitigation, the economic, social, and political costs will be unprecedented. Viable mitigation options exist on both the supply and demand sides but to have substantial impact, they must be initiated more than a decade in advance of peaking.

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.

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.
