Electric vehicles are currently performing a wide variety of off-road functions at warehouses and airports. eTug , LLC has built two electric baggage tractor models that can tow as many as five loaded baggage carts from the terminal to airplane loading gates. eTugs are currently being operated by airlines and ground handling companies at six different airports and more are being evaluated.
The eTug DC-20 model can tow up to 20,000 lbs. and operates on direct DC drive. The eTug AC-30 model has a 30,000-lb. capacity, operates on AC current, and like the DC-20 model, can be charged at a standard 110v outlet or a fast charge station. Regenerative braking, on-board battery charger, backup alarm and rear inching switch are standard on both models.
According to Neil Bennett, president of eTug LLC, "Even if companies are under mandates to switch to environmentally friendly operation, it's hard for companies to spend money during difficult economic times. Our machines operate on zero emissions and offer savings from the first day of operation that directly affect the bottom line. Electric charging costs nine cents for an hour of operation while a gas or diesel tug costs in the three- to four-dollar range for the same hour of operation." Leasing is another option, costing $900 per month compared to $2,200 or more in operating costs of a gasoline vehicle.
"Environmental compliance and reduced fuel costs are available in the off-road sector," Bennett said. "Electric vehicles offer versatility and function at a low cost per unit. Contact Neil Bennett for more information about eTug applications.

The Dallas/Fort Worth International Airport (DFW), with more than 700,000 takeoffs and landings a year, is the third busiest in the world. Because of its expansive size, covering 29 square miles, DFW is a mini-city, with their own fire department and a huge fleet of more than 500 maintenance vehicles, most of which operate on compressed natural gas (CNG). An onsite CNG refueling station, built in 2000, makes it easy for airfield sweepers and other off-road support equipment to stop in and fill up.
DFW uses about 1.7 million gallons of CNG a year, instead of gasoline or diesel fuel, to keep its shuttle buses and other CNG vehicles up and running. Airport employees also use hybrids, like the Toyota Prius, to travel throughout the property. Alternative fuels for this huge fleet help to keep the Texas skies blue and clear. View the MotorWeek video of this story.

The Portland International Airport (PDX) in Oregon has become a dedicated user of alternative fuel vehicles in almost every aspect of operation from baggage loading vehicles to shuttle buses, police vehicles, and street maintenance equipment. PDX began replacing conventional petroleum diesel buses with vehicles fueled with compressed natural gas (CNG) in 1997 and currently has 46 dedicated CNG vehicles including 26 shuttle buses, 6 Ford Crown Victorias, one Honda Civic, one F450 service truck, a forklift, 9 vans and two step vans. PDX also has two bi-fuel CNG/gasoline pickups and two vans. Propane vehicles include four forklifts and 1 small scrubber/sweeper. There are 15 flexible-fuel vehicles fueled with E85 and seven hybrid light-duty vehicles used for police activities.
Biodiesel also plays an important part in the alternative fuel plan. PDX has fueled its diesel vehicles with B20 since 2002 and currently operates 26 heavy-duty on-road vehicles including four buses, 19 trucks and three F450 service vehicles plus 27 additional pieces of off-road equipment.
PDX installed fueling infrastructure to meet its alternative fuel needs. The airport currently has CNG, LPG, and B20 fueling stations on the property, althought it cannot sell fuel to other fleets or the public because of access limitations. PDX is also looking to expand CNG availability by adding an additional fueling station or purchasing back-up components for its existing infrastructure.
Rick Elliott, aviation maintenance superintendent, points to lower emissions and longer operational life, which means more miles between rebuilds, as advantages to the alternative fuel fleet. "Whenever we look at purchasing a vehicle, our first question is 'Is it available in an alternate fuel?'" Elliott said. For more information, contact Rick Elliott at the Port of Portland.

The Carmeuse Lime Mine Company now includes B99 (99% biodiesel; 1% petroleum diesel) in the assortment of biodiesel blends it uses in its underground equipment operating in two Kentucky lime mines. Carmeuse began using B99 (99% biodiesel; 1% petroleum diesel) one year ago at both their Black River (Pendleton County) and Maysville (Mason County) sites. The Maysville mine continues to use B99 exclusively, while the Black River mine uses blends ranging from B50 to B99. Between the two mines, one million gallons of biodiesel are used annually. Biodiesel was not unfamiliar to Carmeuse operations when the company began using the fuel at the higher blend in 2007. Carmeuse officials had worked with the Kentucky Clean Fuels Coalition (KCFC) and the Kentucky Division of Energy to address mining industry regulations for underground air quality. The regulations, established in 2001 by the Mine Safety and Health Administration (MSHA), adopted new limits on human exposure to diesel particulate matter (DMP) in underground mines. MSHA is the governing body that sets limits for the concentrations of DPM in the atmosphere of a mine as well as limits for personnel exposure. A pilot biodiesel program, launched at the Kentucky mines in 2003, was conducted in two phases, using two different biodiesel blends (B20 and B50) with No. 2 diesel. The testing was done in conjunction with the Governor?s Office of Energy Policy and KCFC. The results, published by MSHA, showed a significant reduction in DPM. In the Black River mine study, B35 use resulted in DPM reductions between 16% and 33%. Inside equipment cabs, where DPM concentrations are higher, the DPM reductions were between 40% and 55%. In the Mayfield mine study, B50 use resulted in DPM reductions between 49% and 71%. Since these studies were done in 2003 ( Maysville study and Black River study) both mines have switched to using B99, with the help of the Commonwealth Clean Cities Partnership.?By utilizing biodiesel as their primary fuel, Carmeuse supports the health of their workers and the health of the Kentucky and U.S. farm economy,? said Jeff Lykins, president of KCFC.Contact: Bob Mondron, Sourcing Manager, Carmeuse (Bob.Mondron@carmeusena.com)

Disneyland Resort, Inc. is continuing its commitment to the environment by introducing two initiatives to reduce its petroleum use while maintaining its reputation for excellent guest services. The Resort has begun using compressed natural gas (CNG) to fuel its 16 guest trams that transport guests between Disneyland, Disney's California Adventure park, and parking facilities. The switch to CNG from a diesel/hybrid engine was made possible through a $1.17 million grant from the Carl Moyer Memorial Air Quality Standards Attainment Program, which paid for nearly half the conversion costs. According to Disneyland transportation specialists, using CNG will eliminate the need for approximately 50,000 gallons of diesel per year.
The Carl Moyer grant was created by the California state legislature in 1998 to encourage the use of alternative fuel vehicles. Each year, the California Air Resources Board disburses money to the South Coast Air Quality Management District, which administers Carl Moyer funds in Southern California.
The Resort is also using a special B99 biodiesel made from recycled cooking oil to power its Disneyland Railroad steam trains and the Mark Twain riverboat. The move is expected to save approximately 200,000 gallons of petroleum diesel per year, according to Frank Dela Vara, Disneyland Resort's director of environmental affairs and conservation. The Disneyland Railroad's five trains have been using a soy-based biodiesel since April 2007. The B99 used cooking oil-based biodiesel will continue to reduce emissions by up to 80%.

Cranmore Mountain Resort in North Conway, New Hampshire, has been recognized by the National Biodiesel Board for proving the viability of biodiesel in winter conditions through its use of B20 to operate four snow groomers since 2003. The resort uses more than 20,000 gallons of B20 (20% biodiesel, 80% diesel) each year, which results in a 4,000-gallon reduction in the use of conventional diesel. The resort also invested in a 4,000-gallon above-ground, non-heated biodiesel storage tank with collaborative help from the New Hampshire Department of Environmental Services and the Granite State Clean Cities Coalition.
According to Director of Operations Jim Mersereau, Cranmore's use of biodiesel has resulted in a significant improvement in air quality because it burns cleaner than conventional diesel. "This is especially true when the machines are being worked on in the repair shop," says Mersereau. Employees have also found that not only is biodiesel better for the environment but it is convenient to use. "We have never had any problems with the biodiesel fuel in the cold, and we didn't have to make any modifications to our machines in order to use it," Mersereau says.

Oregon's Portland Water Bureau (PWB) is committed to using the highest blend of biodiesel available. Since 2006, it has been using B99 (99% biodiesel, 1% diesel) in its city-owned, diesel-powered vehicles and equipment from spring through fall and B50 (50% biodiesel, 50% diesel) in the winter.
PWB's switch to B99 is the latest in a string of initiatives aimed at building alternative fuel infrastructure in the region and state. "We're doing our part to increase biodiesel demand and help spur the development of Oregon-based production facilities, reduce greenhouse gas emissions, and decrease reliance on foreign oil," says Portland City Commissioner Randy Leonard. A long-time biodiesel advocate and an instrumental leader in the bureau's switch to biodiesel, Leonard promotes B99 as a cleaner-burning renewable fuel and an opportunity to boost the local economy.
To that end, the biodiesel used by PWB is locally produced. The city's partners in the effort--Oregon-based Star Oil and SeQuential Pacific Biofuels--blend and distribute the fuel, while regional farmers (from Oregon, Washington, Idaho, and Montana) grow the seed crops that eventually become the feedstock for B99. PWB and its project partners are stakeholders in the local Columbia Willamette Clean Cities coalition.
With PWB's approximately 144 vehicles--ranging from backhoes and forklifts to dump trucks and tractors--running on B99, the emissions benefits are adding up. During the first quarter of 2007, the fleet offset:

On August 30, 2007 a new combined liquefied natural gas (LNG) and fast-fill compressed natural gas (L/CNG) clean fueling facility opened in South Los Angeles. LA Mayor Antonio Villaraigosa was on hand to explain how the station will help serve the City's growing fleet of alternative fuel vehicles (AFVs), which now includes 307 LNG solid refuse collection trucks, 54 CNG street sweepers, and various other city-owned AFVs. Los Angeles has the largest municipally-owned alternative fuel solid refuse collection fleet in the U.S. The South LA Fueling Station has a storage capacity of 45,000 gallons of LNG, and is the third in a series of similar stations. The first two stations were constructed in the West San Fernando Valley (45,000 gal.) and East Valley (60,000 gal.). All 3 stations were partially funded using $450,000 in Clean Cities U.S. Department of Energy grant awards received through the California Energy Commission. A fourth station is operating in the Harbor area, at a 6,000-gallon capacity.
The project took over 18 months to build. The station was then put into demonstration/testing mode for 8 months prior to the grand opening. The greatest challenge during the project was the site preparation and cleanup required prior to construction. Some 27,000 tons of contaminated soil were removed and cleaned up over a period of three months at a cost of $330,000.
A total of over $15 million in grants have been secured by the Environmental Affairs Department to help the City's solid resources collection fleet grow in size, and over 4 million gallons of diesel have been displaced since 2000, when the City started using LNG and L/CNG in its alternative fuel in its solid resources collection fleet.

With a population of around 65,000, Hoover, Alabama, is the sixth largest city in the state. The City of Hoover currently operates 179 flex-fuel vehicles as well as 21 other light-duty vehicles, 60 medium- and heavy-duty trucks, two buses, two shuttles, and 96 off-road vehicles on B20, a blend of 20% biodiesel and 80% petroleum diesel. The city currently boasts that 80% of the fuel used by its fleet is alternative fuel.
Hoover's police force operates 130 of the flex-fuel vehicles, which are fueled 100% of the time on E85. The remaining 49 flex-fuel vehicles are used by the city's administative personnel. Hoover has also started a test program to use B20 in its fire trucks and plans to forward the results to the National Fire Protection Association.
Hoover may also be the first municipal government in the U.S. to manufacture its own B100 using waste vegetable oil collected from local restaurants. The city also plans to start home collection of waste vegetable oil by providing gallon jugs to homeowners who want to participate.
"The price of the alternative fuels is below the price of petroleum fuel. With our own B100 production, we might even turn a profit," says David Lindon, fleet management director for the City of Hoover. "The mayor and the city council are committed to clean fuel. It's the right thing to do for our energy security and it's cost effective."

In 2005, after only one month of testing B5 biodiesel fuel in its diesel fleet, Eastman Chemical Company moved all of its diesel vehicles to B20, a blend of 20% biodiesel and 80% petroleum diesel fuel. Now, two years later, the entire fleet has transitioned to B30. The diesel fleet, located at the Kingsport, Tennessee facility, numbers about 200 pieces and includes tractor trailers, cranes, medium-duty trucks, bulldozers, dump trucks, backhoes, and farm tractors. Eastman also has more than 150 pieces of diesel-powered stationary equipment, such as welders, air compressors, generators, and water pumps that are fueled with biodiesel.
The decision to move from B5 to B20 and then from B20 to B30 was based on positive comments from drivers about equipment performance and decreased odor and smoke. Darren Curtis, a staff engineer with Eastman's transportation department, says the company switched to biodiesel because it was an excellent opportunity to do something beneficial for the community and the environment at the same time. "It's not often that something this simple and easy comes along that can have a potentially major impact on the environment and the community."
In mid-2007 Eastman took B20 to a new level using it to fuel its onsite locomotives that are used for in-plant switching operations. According to Curtis, the move has been a smooth one. "We moved the rail system first to B10 and then a month later went to B20. We don't anticipate any unexpected problems based on three things: our previous experience with biodiesel blends, our experience thus far with B10 in the locomotives, and Genesee & Wyoming's (GWI) testing of biodiesel." GWI own the locomotives and perform the in-plant switching, and Eastman provides the fuel. Curtis credits GWI with extensive testing using biodiesel blends.
The switch has triggered a lot of interest in the Northeast Tennessee and Southwest Virginia areas, according to Curtis. The general hope is that other large users of diesel fuel will follow Eastman's lead. "Eastman alone can make a small contribution, but it's going to take everyone working together to make the kind of impact we'd like to see," he says.

In 2001, the Port of Seattle Aviation Division adopted a fleet vehicle purchase policy that required the purchase of alternative fuel vehicles (AFVs), whenever feasible and practical, to replace conventional petroleum vehicles. The Seattle Tacoma (Sea-Tac) International Airport's fleet is currently composed of 60 compressed natural gas (CNG) vehicles, including 16 buses and 41 light-duty vehicles (LDVs)--all of which display the slogan "Doing our share for cleaner air naturally." Sea-Tac's fleet also includes seven propane LDVs, nine hybrid LDVs and 91 ground support units that operate on electricity. In 2005, the Sea-Tac Airport received the Environmental Protection Agency's Clean Air Excellence Award in recognition of the implementation of air quality programs such as the fleet vehicle purchase policy.
The Port required airport taxi and shuttle services to switch to CNG vehicles. Shuttle Express currently has 27 CNG shuttle vans serving the airport. Shuttle Express operates more than 33% of its total trip mileage using the CNG vans. The Seattle-Tacoma International Taxi Association operates all of its 166 taxi cab fleet with CNG-fueled Ford Crown Victorias. The Port of Seattle's Air Quality Web site reports that the CNG fleet is expected to produce 149 fewer tons of carbon monoxide and 24 fewer tons of oxides of nitrogen each year compared to conventional vehicles.
The Port partnered with Clean Energy to install, operate, and maintain a full-service CNG fueling station at Sea-Tac, which is open to the public and operates 24 hours a day. Sea-Tac currently has plans to add an additional public CNG fueling station, as well as increase the number of CNG buses in its fleet.

Located near Eureka, California, the Redwood National and State Parks are currently using a variety of alternative fuels in its fleet. They are using biodiesel (B20) to operate 32 heavy-duty vehicles (HDVs) used for park maintenance. The park also uses five light-duty electric vehicles and two Toyota Prius hybrid electric vehicles (HEVs) for light maintenance and park transportation. In addition, the park has an electric tractor vehicle used to haul cleaning supplies to the restrooms, pick up and transport garbage, and to perform routine maintenance work. "The electric tractor is quieter than a conventional vehicle, and it does not disturb the wildlife as much," says Roads and Trails Supervisor Richard Mayle.Redwood National and State Parks currently has an onsite biodiesel (B20) refueling station. "Biodiesel is inconsistent because it usually takes a few weeks to get a shipment to our remote location. Sometimes the fuel arrives in a few days and other times it takes a couple of weeks," says Mayle. "Biodiesel also costs a little bit more than conventional fossil fuel diesel, but we have noticed that biodiesel is cleaner and seems better for the environment."
