Internal combustion engines (ICEs) power our cars, trucks, big rigs, trains, generator sets, ships, and a host of other applications worldwide. Unfortunately, conventional ICEs boast low efficiency – most convert only 30% of fuel into usable work, and that is under optimal conditions. When accounting for idling and sub-optimal speeds, efficiency drops to 15 to 20%. That means, for every gallon of fuel placed into the engine, only 15 to 20% of the energy in that fuel is ever transferred into usable mechanical energy under typical conditions. The remaining 80 to 85% of energy contained in the fuel is wasted – wasted on friction, losses to heat, incomplete burning, and other inefficiencies characteristic of conventional ICEs.

WASHINGTON – The U.S. Environmental Protection Agency (EPA) and the Department of Energy (DOE) are releasing the 2013 Fuel Economy Guide, giving consumers clear and easy-to-read information to help them choose the most fuel efficient and low greenhouse gas emitting vehicles that meet their needs. The 2013 models include efficient and low-emission vehicles in a variety of classes and sizes, but notable this year is the growing availability of hybrids and the increasing number of electric vehicles.

“This Administration has been working to foster a new generation of clean, fuel-efficient American vehicles, and part of that effort is ensuring that Americans have access to the best possible fuel economy information when they’re choosing a car,” said Administrator Lisa P. Jackson. “The 2013 Fuel Economy Guide provides Americans information about which car on the lot offers the greatest fuel economy and the lowest environmental impact. These are important considerations that can help families save money while protecting their health and the environment.”

“The Fuel Economy Guide gives consumers easily accessible information to help them choose the vehicle that’s right for them,” said Energy Secretary Steven Chu. “Fuel efficient vehicles help American families save money at the pump, continue to deliver on vehicle performance, and help reduce our dependence on foreign oil while limiting carbon pollution.”

This year’s guide gives consumers a broad range of information that they can use to select their next fuel efficient vehicle, whether they want to consider an electric vehicle or one that uses a more conventional fuel. This year, for the first time, EPA and DOE have added a second top ten list of most efficient vehicles — separating advanced technology vehicles from conventional gasoline and diesel vehicles. Electric and plug-in hybrid electric models are the most fuel-efficient and lowest-emission vehicles available today and are becoming more common. At the same time, consumers may still look up the conventional gasoline and diesel models that offer superior fuel efficiency.

The 2013 guide provides an estimated annual fuel cost for each vehicle. The estimate is calculated based on the vehicle’s miles per gallon (mpg) rating and national estimates for annual mileage and fuel prices. The online version of the guide allows consumers to enter their local gasoline prices and typical driving habits to receive a personalized fuel cost estimate. The 2013 guide also includes a greenhouse gas rating for each model.

Consumers may view the guide at and it will be available in hard copy at dealer showrooms. EPA and DOE will update the guide online as more 2013 vehicles become available.

All 2013 model year vehicles will display a new fuel economy and environment label to provide consumers with more comprehensive fuel efficiency information, including five-year fuel costs or savings compared to the average new vehicle, as well as new ratings for greenhouse gas and smog. These labels are required for model year 2013, but some automakers voluntarily adopted the new label design on some 2012 models.

Peake Fuel Solutions LLC, a wholly-owned subsidiary of Chesapeake Energy Corporation, has announced the development of a diesel natural gas conversion kit that could cut heavy-duty truck operators fuel costs by 30 percent.

Diesel natural gas allows trucks to run on a mixture of diesel and up to 70 percent natural gas. When compressed natural gas or liquefied natural gas fuels are not available, trucks retain the ability to run on 100 percent diesel.

Long-term natural gas prices in the $4-6 per mcf range will translate into CNG and LNG prices of around $2.00 per diesel gallon equivalent, or about 50 percent lower than diesel prices, Peake says. Assuming a typical DNG blend, truckers would save about $0.20 per mile on their fuel costs. The return on investment for a DNG conversion kit is typically less than 18 month, Peake estimates.

The Drive Natural Gas Initiative, a collaboration between utilities and producers, has launched a calculator to help fleet owners analyze the cost of converting vehicles to natural gas.

The Natural Gas Fleet Savings Calculator, which was developed for the American Gas Association by product innovation consulting firm Ricardo, is a spreadsheet-based tool designed to evaluate the total cost of ownership. The calculator includes the cost of financing terms and state incentives.

Fleet owners can determine how much trucking fleets would save by converting from diesel-fuel vehicles to natural gas. The tool also allows users to compare the cost savings of switching from gasoline to natural gas.

A natural gas advocacy group has developed a detailed formula to calculate how much trucking fleets would save by converting from diesel-fueled vehicles to natural gas vehicles.

The tool marks the latest effort by the Drive Natural Gas Initiative to move the country away from crude-based transportation fuels, touting compressed natural gas as a cleaner and cheaper alternative.

Using specific fleet characteristics like vehicle cost, miles driven, and maintenance charges, the calculator determines a company’s total cost of operating natural gas vehicles. It also calculates how quickly the lower natural gas fuel cost makes up for the higher vehicle price.

“With the opening of shale gas plays, there’s this new abundance of domestic gas and the price for North American natural gas is significantly lower on an energy basis than petroleum,” said Executive Director Kathryn Clay. “We can see it at the pump today.”

WASHINGTON – As part of the Obama Administration’s all-of-the-above energy strategy, the Energy Department today announced 20 new projects to help states and local governments cut red tape and develop the infrastructure, training and regional planning needed to help meet the demand for alternative fuel cars and trucks, including vehicles that run on natural gas, electricity and propane. These projects build on the important steps the Obama Administration has taken to expand the transportation options available for businesses and communities and improve the fuel efficiency of vehicles in the market today and for years to come.

“Building a clean and secure U.S. transportation system that leverages our domestic energy sources will give American families, businesses and communities more options and reduce fueling costs,” said U.S. Energy Secretary Steven Chu. “At the same time, these projects will help lead the way to further reducing America’s dependence on foreign oil and protecting our nation’s air and water.”

Through the Department’s Clean Cities initiative, these projects address a range of community infrastructure and training needs, such as providing safety and technical training for fleet operators, mechanics, first responders and code officials; streamlining permitting and procurement processes; and helping public and private fleets integrate petroleum reduction strategies into their operations.

Fleet managers and operators are searching for ways to combat rising fuel prices and meet government fuel economy regulations. The current corporate average fuel economy (CAFE) standards call for an average of about 29 miles per gallon, with a gradual increase leading to 35.5 mpg by 2016. With the new mandate, the government standards require automakers to almost double the average fuel economy of new cars and trucks by 2025 – calling for an average fuel economy of 54.5 mpg.

With the demands of fleet managers and operators voiced, vehicle manufacturers are scrambling for a way to increase the fuel efficiency of their vehicles. There are many steps to take to increase fuel efficiency: start stop technology, recovering energy from shock absorbers and regenerative braking, but some provide a bigger bang for the buck than others. Micro hybrids, or vehicles using start stop technology, and recovering energy from shock absorbers improve the vehicles’ fuel efficiency by only about 2 to 3 percent. The clear leader is regenerative braking, which can improve fuel efficiency by a whopping 20 to 30 percent. Evaluating the primary energy storage solution for these initiatives is typically the best place for carmakers to start, as choosing the right energy storage technology will further increase the fuel efficiency gain and position the vehicle to be attractive to buyers. Vehicle manufacturers are concluding that using ultracapacitor technology, as opposed to batteries, is the best way to achieve this high fuel efficiency and offer vehicles that consumer want to buy. Here’s why.

GE will collaborate with Clean Energy Fuels in its plan to provide liquefied natural gas as a fueling option at truck stops across the country, the companies announced Tuesday.

Clean Energy, which is backed by Texas investor T. Boone Pickens, said it would buy two MicroLNG plants from GE Oil & Gas, with each plant capable of producing 250,000 gallons of LNG per day.

The GE plants would be able to rapidly transform dry natural gas into LNG for efficient use in long-haul trucks and would support Clean Energy’s plan to add 150 LNG refueling stations at truck stops across the country by 2014 , the companies said.

LNG is more expensive than natural gas, but still far cheaper than diesel and can provide the same driving range and power as the conventional  trucking fuel, gas advocates say.

Truckers switching to LNG can cut their fuel costs more than 25 percent and reduce their greenhouse gas emissions, the companies said.

The MicroLNG plants will be especially significant because they can  generate LNG at any point along a natural gas distribution network, the companies said. No specific site for the plants has yet been developed.

“With an abundance of cleaner, more affordable natural gas here in the U.S., this is an important opportunity for GE to join Clean Energy in changing the way America drives,” GE  Chairman and CEO Jeff Immelt said in a statement. “It’s also a critical step in developing a natural gas-for-transportation fuel model that can be easily exported to other countries interested in exactly these kinds of breakthrough projects.”

Booming production of natural gas from shale has made the resource especially cheap in the United States, making it an increasingly attractive option as a fuel and power resource. But the United States lags far behind other nations in its use of natural gas for transportation, with only one consumer car model available and few refueling stations.

Hertz and Liberty Tire Recycling have launched what they call the first nationwide tire recycling program in the U.S. car rental industry.

Hertz says the program also makes it the first to commit to zero landfill waste for tires.

Under the program, Hertz will use Liberty’s nationwide service to collect its used tires, more than 160,000 annually, which will be transformed into a range of products for playgrounds, public parks, highways and other applications.

The companies say that volume of tires could produce enough rubber mulch for 366 playgrounds, or could pave 20 miles of a four-lane highway with rubber-modified asphalt, which reduces urban heat island effects when compared to conventional asphalt. Rubberized asphalt also rides quieter, lasts longer, and uses significantly less paving material than traditional asphalt, Liberty says.

Liberty Tire Recycling describes itself as the largest tire recycling company in North America. Its recycled rubber feedstock produces a range of products including mat flooring and crumb rubber for composite railroad crossties.

Hertz’s sustainability efforts include offering a collection of alternative fuel and high-MPG vehicles, from electric vehicles to clean diesel, in its Green Traveler Collection lineup. The company’s car sharing service, Hertz On Demand, offers EV and hybrid options including the Nissan LEAF, Chevy Volt and Mitsubishi iMiev. Recently, Hertz also expanded its electric car rental program through a pilot initiative with Plugless Power, which allows EVs to charge without being plugged into an outlet.

In July Hertz completed a 229 kW solar system at its global headquarters building in Park Ridge, NJ, and announced plans to build 11 additional solar installations totaling 2.2 MW.
