Many counties and cities in Florida are developing resilience plans to help them minimize damage from hurricanes and accelerate recovery. Fuel diversification can add to Florida’s transportation resilience because if the supply of one fuel gets disrupted during a hurricane, there is a good chance that the supplies of other fuels are still available. The Florida Alternative Transportation Fuel Resilience Plan aims to address these factors and create a strategy for how three alternative fuels (natural gas, propane, and electricity) can best be employed to improve transportation resilience in Florida. It does this through a combination of literature review and stakeholder engagement for best practices, vehicle technology recommendations, the creation of three tools (with descriptions and brief guides included), and charting how stakeholders coordinate to overcome these hurdles.

Clean Cities Coalitions 2020 Activity Report Singer, M.; Johnson, C. 12/29/2021 Reports

National Renewable Energy Laboratory, Golden, Colorado

Clean Cities coalition activities resulted in an EUI of nearly 1 billion GGE, comprised of net alternative fuels used and energy savings from efficiency projects, in 2020. Clean Cities coalition and stakeholder participation in vehicle and infrastructure development projects remained strong, although transportation activity and resulting EUI decreased in 2020 due to the COVID 19 pandemic. Coalition-reported activities prevented nearly 5 million carbon dioxide-equivalent tons of emissions (only GHG emissions are reported here; criteria pollutants and other emissions are not included in this report). The GHG benefits increased in 2020 despite a decrease in EUI because coalitions focused more on technologies with higher GHG benefits per GGE reduced and because the lifecycle of many alternative fuels such as electricity or biofuels is becoming less carbon intense. Coalitions were successful in securing project grant awards from numerous outside (non-DOE) sources. The 90 project grant awards in 2020 generated $151 million in funds from coalition members and project partners in addition to $12.8 million in DOE grant funds. Coalitions also collected $1.1 million in stakeholder dues and $3.1 million in operational funds from host organizations. In macro terms, this non-DOE supplemental funding represents a 4:1 leveraging of the $38 million that was included in the VTO Technology Integration budget in 2020. Clean Cities coordinators spent nearly 135,700 hours pursuing their coalitions’ goals in 2020. The average coordinator is quite experienced and has held the coordinator position for nearly eight years. Coordinators logged more than 3,290 outreach, education, and training activities in 2020, which reached an estimated 31 million people. Activities that reached underserved communities were tracked for the first time in 2020 and accounted for 17% of all activities.

Clean Cities coalition activities resulted in an energy use impact (EUI) of over 1 billion gasoline-gallons equivalent (GGE), comprised of net alternative fuels used and energy savings from efficiency projects, in 2018. Participation in vehicle and infrastructure development projects remained strong, as did alternative fuel use and resulting overall EUI. Clean Cities coalition activities reduce emissions as they impact energy use. Coalition-reported activities prevented 5 million carbon dioxide-equivalent tons of emissions (only greenhouse gas [GHG] emissions are reported here; criteria pollutants and other emissions are not included in this report). Coalitions were successful in securing project grant awards from numerous (non-DOE) outside sources. For other Federal, State, and local agencies and private sector foundations, see funding section on page 25. The 84 project grant awards in 2018 generated $251 million in funds from coalition members and project partners along with $1.9 million in DOE grant funds. Coalitions also collected $1.1 million in stakeholder dues and $2.9 million in operational funds from host organizations. In macro terms, this supplemental funding represents nearly a 7:1 leveraging of the $37.8 million that was included in the VTO Technology Integration budget in Fiscal Year 2018. Clean Cities coordinators spent nearly 121,000 hours pursuing their coalitions' goals in 2018. The average coordinator is quite experienced and has held his or her position for at least eight years.

Fuel Diversification to Improve Transportation Resilience: A Backgrounder Johnson, C. 6/6/2019 Presentations

National Renewable Energy Laboratory, Golden, Colorado

Transportation fuel (like most other necessities) can be made more resilient to natural disasters by improving the redundancy of its supply, increasing local storage, strategizing access to that storage, expediting resupply, and improving the efficiency at which that fuel is used for transportation purposes. Alternative fuels such as natural gas, propane, and electricity have very different sources and distribution, and therefore add resilience to the fuel supply through redundancy. However, it is important to examine the inter-dependencies of these fuels and timing that may present vulnerabilities during a hurricane. This workshop presented a variety of perspectives to assist in making Tampa Bay's transportation system more resilient through the strategic use of alternative fuels.

Using Natural Gas for Vehicles: Comparing Three Technologies 1/4/2016 Brochures & Fact Sheets

U.S. Department of Energy, Energy Efficiency & Renewable Energy, Washington, D.C.

In the United States, natural gas as a fuel is typically used for medium- or heavy-duty vehicles in centrally-fueled fleets. It has been proposed for greater use as a fuel for light-duty vehicles (LDVs). This can mean burning natural gas in an internal combustion engine like those used in most gasoline- and diesel-powered vehicles on the road today. However, natural gas can also serve as the energy source for plug-in electric or hydrogen fuel cell electric vehicles. This fact sheet compares some efficiency and environmental metrics for three possible options for using natural gas in LDVs.

Developing a Natural Gas-Powered Bus Rapid Transit Service: A Case Study Mitchell, G. 11/4/2015 Reports

National Renewable Energy Laboratory, Golden,Colorado

The Roaring Fork Transit Authority (RFTA) and its VelociRFTA Bus Rapid Transit (BRT) program are unique in many ways. For example, VelociRFTA was the first rural BRT system in the United States and the operational environment of the VelociRFTA BRT is one of the most severe in the country, with extreme winter temperatures and altitudes close to 8,000 feet. RFTA viewed high altitude operation as the most challenging characteristic when it began considering the use of natural gas. RFTA is the second-largest public transit system in Colorado behind Denver's Regional Transportation District (RTD), and it is one of the largest rural public transit systems in the country. In 2013, RFTA accepted delivery of 22 new compressed natural gas (CNG) buses that went into service after completion of maintenance and refueling facilities earlier that year. This paper examines the lessons learned from RFTA's experience of investigating--and ultimately choosing--CNG for their new BRT program and focuses on the unique environment of RFTA's BRT application; the decision process to include CNG fueling in the project; unforeseen difficulties encountered in the operation of CNG buses; public perception; cost comparison to competing fuels; and considerations for indoor fueling facilities and project funding.

Motor Fuel Excise Taxes 9/1/2015 Brochures & Fact Sheets

National Renewable Energy Laboratory, Golden Colorado

A new report from the National Renewable Energy Laboratory (NREL) explores the role of alternative fuels and energy efficient vehicles in motor fuel taxes. Throughout the United States, it is common practice for federal, state, and local governments to tax motor fuels on a per gallon basis to fund construction and maintenance of our transportation infrastructure. In recent years, however, expenses have outpaced revenues creating substantial funding shortfalls that have required supplemental funding sources. While rising infrastructure costs and the decreasing purchasing power of the gas tax are significant factors contributing to the shortfall, the increased use of alternative fuels and more stringent fuel economy standards are also exacerbating revenue shortfalls. The current dynamic places vehicle efficiency and petroleum use reduction polices at direct odds with policies promoting robust transportation infrastructure. Understanding the energy, transportation, and environmental tradeoffs of motor fuel tax policies can be complicated, but recent experiences at the state level are helping policymakers align their energy and environmental priorities with highway funding requirements.

Alternative Transportation Refueling Infrastructure in the United States 2014: Status and Challenges Greene, D.L. 1/13/2015 Reports

University of Tennessee, Howard H. Baker JHr. Center for Public Policy, Knoxville, Tennessee

Lack of adequate refueling infrastructure is a major barrier to the success of alternative motor fuels. A transition from fossil petroleum to alternative, low-carbon transportation fuels appears to be necessary to mitigate the adverse impacts of global warming, strengthen energy security and meet air quality standards. Finding effective combinations of business models and public policies to accomplish a transition to alternative fuels poses a new and difficult challenge. Focusing on highway vehicles, this paper reviews the motivation for transition to alternative fuels, the current status of alternative fuel refueling infrastructure in the U.S., the costs of such infrastructure and business models and policies that have been proposed to achieve a successful transition. The goal of this paper is to serve as a basis for innovative thinking and discussion rather than as a comprehensive analysis of the issue. Infrastructure for producing and delivering fuels to refueling stations is equally important but is outside the scope of this paper.

Geography of Existing and Potential Alternative Fuel Markets in the United States Johnson, C.; Hettinger, D. 11/3/2014 Reports

National Renewable Energy Laboratory, Golden, Colorado

When deploying alternative fuels, it is paramount to match the right fuel with the right location, in accordance with local market conditions. We used six market indicators to evaluate the existing and potential regional market health for each of the five most commonly deployed alternative fuels: electricity (used by plug-in electric vehicles), biodiesel (blends of B20 and higher), E85 ethanol, compressed natural gas (CNG), and propane. Each market indicator was mapped, combined, and evaluated by industry experts. This process revealed the weight the market indicators should be given, with the proximity of fueling stations being the most important indicator, followed by alternative fuel vehicle density, gasoline prices, state incentives, nearby resources, and finally, environmental benefit. Though markets vary among states, no state received 'weak' potential for all five fuels, indicating that all states have an opportunity to use at least one alternative fuel. California, Illinois, Indiana, Pennsylvania, and Washington appear to have the best potential markets for alternative fuels in general, with each sporting strong markets for four of the fuels. Wyoming showed the least potential, with weak markets for all alternative fuels except for CNG, for which it has a patchy market. Of all the fuels, CNG is promising in the greatest number of states--largely because freight traffic provides potential demand for many far-reaching corridor markets and because the sources of CNG are so widespread geographically.

Biogas is a proven source of energy used in the United States and around the world for decades. As such, biogas systems can and should be an integral part of America's energy strategy moving forward. The Biogas Opportunities Roadmap builds on progress made to date to identify voluntary actions that can be taken to reduce methane emissions through the use of biogas systems and outlines strategies to overcome barriers limiting further expansion and development of a robust biogas industry in the United States.
