Guide for Identifying and Converting High-Potential Petroleum Brownfield Sites to Alternative Fuel Stations
5/1/2011
Former gasoline stations that are now classified as brownfields can be good sites to sell alternative fuels because they are in locations that are convenient to vehicles and they may be seeking a new source of income. However, their success as alternative fueling stations is highly dependent on location-specific criteria, how to prioritize them, and then applies that assessment framework to five of the most popular alternative fuels?electricity, natural gas, hydrogen, ethanol, and biodiesel.
The second part of this report delves into the criteria and tools used to assess an alternative fuel retail site at the local level. It does this through two case studies of converting former gasoline stations in the Seattle-Eugene area into electric charge stations.
The third part of this report addresses steps to be taken after the specific site has been selected. This includes choosing and installing the recharging equipment, steps to take in the permitting process and key players to include.

Clean Alternative Fuel Vehicle and Engine Conversions; Final Rule
4/8/2011
EPA is streamlining the process by which manufacturers of clean alternative fuel conversion systems may demonstrate compliance with vehicle and engine emissions requirements. Specifically, EPA is revising the regulatory criteria for gaining an exemption from the Clean Air Act prohibition against tamperingfor the conversion of vehicles and engines to operate on a clean alternativefuel. This final rule creates additional compliance options beyond certification that protect manufacturers of clean alternative fuel conversion systems against a tampering violation, depending on the age of the vehicle orengine to be converted. The new options alleviate some economic and proceduralimpediments to clean alternative fuel conversions while maintainingenvironmental safeguards to ensure that acceptable emission levels from converted vehicles are sustained.

Compressed Natural Gas (CNG) Transit Bus Experience Survey
9/1/2010
The U.S. Department of Energy (DOE) and the National Renewable Energy Laboratory (NREL) commissioned this survey to collect and analyze experiential data from U.S. transit agencies with varying degrees of compressed natural gas (CNG) bus and station experience. This information helps DOE and NREL determine areas of CNG transit bus success and priority areas for which further technical or other assistance might be required to enable success.This survey was intended to focus on the problems, mistakes, and lessons learned the hard way. By focusing on and reporting the negative experiences, it is hoped that others can avoid these pitfalls and learn from the experience of the pioneers in the industry.

Natural Gas Vehicles: Status, Barriers, and Opportunities
8/1/2010
In the United States, recent shale gas discoveries have generated renewed interest in using natural gas as a vehicular fuel, primarily in fleet applications, while outside the United States, natural gas vehicle use has expanded significantly in the past decade. In this report for the U.S. Department of Energy's Clean Cities Program we have examined the state ofnatural gas vehicle technology, current market status, energy and environmentalbenefits, implications regarding advancements in European natural gas vehicletechnologies, research and development efforts, and current market barriers andopportunities for greater market penetration. The authors contend that commercial intracity trucks are a prime area for advancement of this fuel. Therefore, we examined an aggressive future market penetration of natural gas heavy-duty vehicles that could be seen as a long-term goal.

Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles
3/1/2010
Technologies and Approaches to Reducing the Fuel Consumption of Medium- and Heavy-Duty Vehicles evaluates various technologies and methods that could improve the fuel economy of medium- and heavy-duty vehicles, such as tractor-trailers, transit buses, and work trucks. The book also recommends approaches that federal agencies could use to regulate these vehicles' fuel consumption. Currently there are no fuel consumption standards for such vehicles, which account for about 26 percent of the transportation fuel used in the U.S.
The book estimates the improvements that various technologies could achieve over the next decade in seven vehicle types. For example, using advanced diesel engines in tractor-trailers could lower their fuel consumption by up to 20 percent by 2020, and improved aerodynamics could yield an 11 percent reduction. Hybrid powertrains could lower the fuel consumption of vehicles that stop frequently, such as garbage trucks and transit buses, by as much 35 percent in the same time frame.
The Contribution of Natural Gas Vehicles to Sustainable Transport 2010
1/1/2010
The number of natural gas vehicles and fuel stations has grown very strongly in the past decade and continues to do so, although it is still a niche market from the perspective of transport, representing less than 1% of the world road fuel consumption. Natural gas can play a significant role in cutting vehicle carbon dioxide emissions but over the long term there will need to be a commitment to transition to very low CO2 gas sources. Depending on the context, NGVs can have strong benefits in different countries by improving air quality, reducing noise in urban areas; diverting oil from domestic consumption to export; and improving energy security.

An Action Plan for Cars: The Policies Needed to Reduce U.S. Petroleum Consumption and Greenhouse Gas Emissions
12/1/2009
Reducing petroleum consumption and GHG emissions from cars and light?]duty trucks in the United States over the next several decades requires that we implement a clear and coordinated set of policies now. This report describes a portfolio of policies which, in the view of the authors, is needed to put personal vehicle transportation on the road to sustainability in the longer term. To incentivize adoption of more fuel efficient vehicles, we propose coupling existing near?]term fuel economy standards with a feebate incentive program and gradual increases in fuel taxes. We further propose driver education initiatives that would give vehicle owners information on how to maximize fuel savings in their purchase and driving decisions. Finally, we underscore the need for a long?]term strategy for fuels that evaluates fuels?]related programs based on their contribution to reducing life?]cycle petroleum consumption and greenhouse gas (GHG) emissions. Together, these policies offer a robust plan of action that will focus and streamline current efforts to achieve these two important national goals. Perhaps most importantly, this plan lays a much?]needed foundation for a comprehensive, adaptable long?]term policy effort. A more detailed summary of the recommended set of policy measures can be found in Section 2.

Clean Cities Annual Metrics Report 2008
9/1/2009
Each year, the U.S. Department of Energy (DOE) asks Clean Cities coordinators to submit an annual report of their activities and accomplishments for the previous calendar year. Approximately 412 million gallons of gasoline were displaced through the Clean Cities efforts in 2008?14% more than in 2007. This displacement represents the combined results of the activities reported by coalitions (as analyzed by NREL) and the impacts of the Fuel Economy Guide and related activities (as estimated by ORNL). Three major changes were made to the Clean Cities survey this year: E10 is no longer counted toward petroleum displacement goals, coordinators no longer relied on a default assumption for the percent of time flex-fueled vehicles used alternative fuel, and B20 was moved from the AFV to the blends category. The first of these changes substantially reduced the reported petroleum displacement by blends from what they otherwise would have been in 2008. AFVs still accounted for the largest share (48%) of the total 412-million-gallon displacement. Fuel economy impacts (combined impacts of coalition and ORNL activity) were responsible for displacing 129 million gallons. The use of biofuels (ethanol and biodiesel) as fuels for AFVs and in low-level biodiesel blends displaced 100 million gallons, or 24% of the total, and idle reduction and HEV technologies combined to displace 20 million gallons. 2008 was the first year that greenhouse gas (GHG) reductions were estimated for Clean Cities activities. The program kept a total of 2.7 million tons of carbon dioxide equivalent (CO2e) from being emitted to the atmosphere?the equivalent of removing over 507,000 passenger cars from U.S. roads.

CNG Fuel System Inspector Study Guide
1/1/2009
The CSA test contains approximately sixty multiple choice questions. There may be additional test questions included that are for evaluation purposes only and will not be part of the final scoring. The questions are based on expert opinions from a cross section of the CNG industry after consideration of the skills and knowledge that a minimally qualified applicant should have. They are taken in proportion to their importance from a carefully constructed set of objectives or tasks that inspectors would be expected to perform.
In preparation for taking the exam, you should first evaluate yourself against these objectives. Honestly consider if you are confident that you know each specific task listed in the following Task List. Note the percentage of questions you can expect in each category and check Yes (Y) or No (N) as you grade yourself. This will form the basis for any additional study you need prior to taking the test.
