Question of the Month: How can I compare the energy content of alternative fuels and gasoline or diesel? What implications does this have for overall fuel and vehicle comparisons?

April 26, 2017 by Clean Cities

Measuring Fuels: Understanding and Using Gasoline Gallon Equivalents
Alternative fuels have varying energy densities and are measured using a number of different units, which can make comparing them tricky. The gasoline gallon equivalent (GGE) unit allows drivers to make apples-to-apples comparisons of a given quantity of energy from alternative fuels and assess which fuel best suits their needs. Understanding the energy content of fuels can help inform comparisons of fuel prices and vehicle driving range.

What is a GGE? How about a DGE?

A GGE is a standardized unit used to compare the energy content of all fuels. This unit quantifies the amount of alternative fuel that has the equivalent energy content of one gallon of conventional gasoline. For medium- and heavy-duty vehicle fuel applications, diesel gallon equivalent (DGE) is often used.

How are GGE and DGE values determined?

Energy content is measured in British thermal units (Btus) per gallon of fuel, and is often referred to as the lower heating value of the fuel. To calculate GGE and DGE, the energy content of one gallon of gasoline or diesel is divided by the energy content of the comparison fuel. For example, conventional gasoline has an energy content of 116,090 Btus per gallon, while propane has an energy content of 84,250 Btus per gallon. As such, 1.38 gallons of propane has the same amount of energy as one gallon of conventional gasoline.

The table below displays the energy content, GGE, and DGE values of conventional and alternative fuels.

Biodiesel (B20) 126,700 Btu/gallon 0.92 gallon 1.01 gallon

* Lower heating value. Source for CNG and hydrogen (Btu/ft3): Transportation Energy Data Book, Edition 35. Source for remaining values: Alternative Fuels Data Center (AFDC) Fuel Properties.

** E85 that is sold in the United States today actually contains, on average, approximately 70% ethanol. Therefore, E85 energy content calculated as [(.70) x (E100 energy content)] + [(.30) x (gasoline energy content)]

*** Electric vehicles are more efficient (on a Btu basis) than combustion engines, which should be taken into account when calculating and comparing miles per GGE (see below).

The values in the table above can help standardize fuel amounts for comparisons. For example, if you have 10,000 ft3 of CNG, you can determine the equivalent number of GGEs by dividing by 125.77 ft3 to get 79.5 GGE. Similarly, to determine the number of DGEs, you would divide by 139.21 ft3 to get 71.83 DGE.

How are GGE and DGE used to compare fuel prices?

Fuel prices can be represented in dollars per GGE or DGE for consistency in pricing between fuels. For that reason, the Clean Cities Alternative Fuel Price Report shows prices on an energy-equivalent basis (Table 3 in recent reports). If values for price per GGE or DGE are not available, you can do the calculation on your own. For instance, if one gallon of E85 is $2.04, you would multiply by 1.32 (see table above ) to find that this price equates to $2.69 per GGE after adjusting for energy content.

What are the factors that impact how far I can drive between fill ups?

The energy content of fuels is one factor that affects driving range. Filling up with a less energy-dense fuel often means that you will not be able to drive as far. However, tank size and vehicle efficiency also play a significant role.

Some alternative fuel vehicles (AFVs) have similar tank sizes to conventional vehicles, while others have larger fuel tanks to compensate for the difference in energy content. For example, vehicles that run on propane and biodiesel typically have similarly sized fuel tanks as their conventional fuel counterparts. As you can see in the table above, both of these fuels have lower energy densities than their conventional fuel counterparts, which subsequently can result in lower fuel economy and shorter range per tank. In the case of propane, bi-fuel vehicles are available that can operate on both conventional fuel and propane for extended driving range. In addition, propane and biodiesel offer many other benefits that can offset this difference.

CNG and hydrogen vehicles, on the other hand, often have larger tanks to offset the lower energy densities associated with these fuels. Fleets and drivers purchasing a CNG vehicle may have the option to install an additional CNG storage tank onboard the vehicle. Alternatively, bi-fuel CNG vehicles are also available to extend the range. As for hydrogen, these vehicles tend to have larger fuel tanks overall.

Tank size is not the only other factor that affects range; vehicle efficiency also plays a role. For instance, all-electric vehicles (EVs) are significantly more efficient than conventional gasoline vehicles. According to FuelEconomy.gov, EVs use anywhere from 59% to 62% of the electricity from the grid to power the vehicle, while conventional gasoline vehicles can only convert 17% to 21% of the energy from gasoline to power the vehicle. This is one reason why EVs have such significant fuel economy advantages over conventional vehicles, even when you are comparing the fuels on an energy-equivalent basis.

New and Improved! AFLEET Tool 2016

May 31, 2016 by Clean Cities

What is the AFLEET Tool, how can I use it to make decisions about alternative fuels, and what are the recent improvements?

Argonne National Laboratory’s Alternative Fuel Life-Cycle Environment and Economic Transportation (AFLEET) Tool allows you to examine both the environmental and economic costs and benefits of alternative fuel and advanced vehicles. By entering data about your light- or heavy-duty vehicle(s), you can estimate petroleum use, greenhouse gas (GHG) emissions, air pollutant emissions, and cost of ownership.

AFLEET uses data from Argonne’s Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model and the U.S. Environmental Protection Agency’s (EPA) Motor Vehicle Emissions Simulator (MOVES) model to estimate life cycle (well-to-wheel) GHG and tailpipe air pollutant emissions. Users can either use the model’s default values or get even more accurate results by customizing the tool with their real life vehicle or fleet data. By using AFLEET’s simple input mechanism, users can answer questions such as:

  • What are the emissions savings of replacing a conventionally fueled fleet with alternative fuel vehicles?
  • What is the incremental cost, and potential return on investment, of buying a flexible fuel vehicle?
  • How many passenger vehicles will be “taken off the road” by using natural gas refuse trucks?

Fleets and others that have been using AFLEET since its original release in 2013 will be pleased to hear that AFLEET has been updated to reflect more recent emissions data. In addition, Argonne added new features to help users formulate a more complete picture of the costs and benefits of alternative fuels.

Updates include:

  • Fuel Prices: AFLEET uses public and private station pricing based on the 2015 average Clean Cities Alternative Fuel Price Report data. In addition, fuel pricing is now state-based rather than based on a national average. Users may also input a range of fuel prices to determine effects on simple payback models.
  • Infrastructure Costs: The updated version of AFLEET features data on fueling station and electric vehicle supply equipment infrastructure construction, operation, and maintenance costs. Users may also calculate other infrastructure-related costs, such as public station out-of-route mileage and fueling labor costs.
  • Latest Vehicle and Emission Data: AFLEET uses the latest GREET 2015 air pollutant emissions data, which includes updated heavy-duty fuel economy and emissions data, data for fuel cell electric vehicles, and updated life cycle data for renewable natural gas. AFLEET has also been updated to use the most recent version of EPA’s MOVES data, 2014a.
  • Externality Costs: AFLEET output data now includes externality costs of national petroleum use and GHG emissions. Externality costs are the indirect damages associated with fuels that are not explicitly captured by the marketplace (e.g., property damages from increased flood risk as a result of climate change). Externality cost estimates will be useful in putting local vehicle and fleet decisions in a national perspective.

For information about and instructions for using AFLEET, refer to Argonne’s AFLEET User Guide.

Florida Power & Light Achieves Key Emissions Reductions with Biodiesel

May 12, 2016 by Clean Cities

“Powered by Biodiesel” decals adorn Florida Power & Light Company’s (FPL) diesel vehicles as they traverse Florida and beyond. The signage highlights the key role this advanced biofuel is playing in the company’s sustainability strategy.

“FPL operates one of the largest “green fleets” in the country, with approximately 1,840 biodiesel-powered vehicles and 570 electric and hybrid electric vehicles – allowing us to reduce emissions and pass on fuel savings to our customers,” said Patti Earley, FPL Fleet Fueling Operations Specialist and the newest member of the Biodiesel Ambassadors program supported by the National Biodiesel Board. “In 2015 alone, our fleet saved 684,000 gallons of petroleum fuel and prevented more than 6,600 tons of carbon dioxide emissions.”

FPL’s journey to revolutionize its fleet started in 2006 when it became the first energy company to place into service a medium-duty hybrid-electric bucket truck. Today the company’s fleet includes both electric and hybrid trucks that use up to 60 percent less fuel and reduce exhaust emissions up to 90 percent.

fpl_biodiesel“At FPL, we pride ourselves on being good stewards of the environment and have developed a comprehensive sustainability strategy,” she said. “Biodiesel is the perfect fit because it’s renewable, sustainable and cleaner burning – there is no downside,” she said.

Earley explained that FPL vehicles need reliable fuel because they are constantly put to the test by working in extremely challenging environments. FPL crews drive the trucks all over the Sunshine State, on-road and off-road, often traveling up to 300 miles a day in extreme heat. They also plow through swampy terrain in the Florida Everglades or bull across inaccessible roads to restore power.

“Our 1,840 biodiesel vehicles have accumulated more than 100 million miles using B20 without encountering any biodiesel-related issues,” said Earley. FPL’s vehicle evaluations have demonstrated no appreciable change in fuel economy, engine wear, or driver acceptance with biodiesel.

FPL purchases more than 500,000 gallons of B100 annually. While the company primarily powers its fleet with B20, it’s also used blends of up to B35. “Because biodiesel is a drop-in fuel, there is no infrastructure issues involved, making it very easy to use,” Earley added.

Biodiesel on the Road

When Superstorm Sandy devastated much of the East Coast in 2012, FPL crews headed north to help restore power. With fuel in short supply, FPL crews took transport trailers full of B20 on the road with them. They not only fueled their own vehicles with B20, but pumped it into a variety other utility vehicles that needed fuel.

“No one really knew the difference,” said Earley. “But we knew that we had fuel we could count on that also happens to be better for the environment.”

About FPL

FPL provides energy to more than 4.8 million customers in Florida, with its fleet of 3,800 vehicles covering 27,000 square miles of service territory. In 1999, the company began experimenting with B20 in diesel vehicles in two locations. Since then, the biodiesel program has achieved much success, surpassing expectations.

In 2010, Ford Motor Company asked FPL to participate in an unprecedented “extreme-duty” B20 testing program with 2011 Ford F-Series Super Duty® diesels. Positive results help spur the decision to make all 2011 Ford F-Series Super Duty® diesel pickups fully compatible with B20.

In 2008, FPL earned the National Biodiesel Board’s annual Eye on Biodiesel Award for its leadership as a biodiesel champion. FPL fields about a dozen calls a month from others interested in transitioning to biodiesel, and educates them about use of the fuel.


 

The National Biodiesel Board is funded in part by the United Soybean Board and state soybean board checkoff programs.

Tax Extenders Legislation Clears Congress: Key Tax Credits Reinstated Through 2014

December 18, 2014 by Clean Cities

IMG_4856-0.JPG

On Tuesday night, December 16, the Senate approved legislation sent from the House that extends the life of a number of tax breaks through tax year 2014. Included in the package are a number of credits important to fleets, of which are outlined below.

Alternative Fuel Excise Tax Credit – $.50 per gallon alternative fuel tax credit for compressed natural gas and propane when used as a vehicle fuel.
Biodiesel Production and Blending Tax Credit – Qualified biodiesel producers or blenders are eligible for an income tax credit of $1.00 per gallon of pure biodiesel or renewable diesel produced or used in the blending process.
Alternative Fuel Infrastructure Tax Credit – A 30 percent credit for installing vehicle refueling property for alternative fuel, such as pumps for ethanol or liquefied natural gas.
Bonus Modified Accelerated Cost Recovery System (MACRS), commonly referred to as Bonus Depreciation – allows extra depreciation to be taken for 50 percent of a truck’s purchase price, with an extra bonus depreciation deduction of up to $8,000 for automobiles, light trucks, vans, and SUVs.
President Obama is expected to sign the tax extenders legislation within days. As mentioned, the measure is only applicable to the 2014 tax year, which means the credits will not be renewed for tax year 2015 unless the new Congress takes the matter up again.

Governors Ask for Higher Biodiesel, Ethanol Mandates

October 3, 2014 by Clean Cities

A group representing 33 state governors asked the administration to increase the blending mandates for biodiesel and a certain kind of ethanol.

Illinois Gov. Pat Quinn (D) and Iowa Gov. Terry Branstad (R), the leaders of the Governors’ Biofuels Coalition, said potential decreases in the Environmental Protection Agency’s (EPA) Renewable Fuel Standard (RFS) volumes for biodiesel and cellulosic ethanol could hurt the nascent waste biofuel industry.
