Oberon DME Receives RFS Approval

September 18, 2014 in Alternative Fuels

September 3, 2014 – Southern California’s Oberon Fuels Inc. (Oberon) announced that the U.S. EPA approved its dimethyl ether (DME) as a renewable identification number (RIN) eligible product under the Renewable Fuel Standard (RFS).   EPA determined that compared to baseline diesel fuel, the biogas-based DME produced by Oberon lead to in an estimated 68% reduction in greenhouse gases.

Obern converts natural gas and biogas from various waste streams (i.e. wastewater, landfills, and animal and food waste) to commodities such as DME. Fuel-grade DME is currently being used by Volvo Trucks in some of its commercial heavy-duty trucks.

DME is a clean-burning fuel with diesel-like performance and propane-like handling properties. Due to the fuel’s clean-burning properties no diesel particulate filter is required.  The fuel is stored in the vehicle similar to propane, with a tank pressure of about 75 psi.  The Oberon Fuels website has additional information on how they process DME and vehicle requirements.

San Diego Plumbing Fleet Gets Hybrids

September 5, 2014 in Fleets, Fuel Economy, Hybrid Vehicles, Uncategorized

One of San Diego’s certified green plumbers, Anderson Plumbing, Heating & Air, is adopting a more fuel-efficient vehicle option for their fleet: the diesel-electric hybrid Hino COE (cab-over engine). The fleet currently has one Class 5 Hino 195h diesel-electric hybrid, with two more to be added. Anderson reported averaging 14 miles per gallon (mpg) with the hybrid Hino compared to 8 mpg with the their previous Isuzu trucks.

Utilizing hybrid technology results in monetary fuel and maintenance savings and environmental benefits of petroleum displacement and greenhouse gas emission savings.  For example, say one of Anderson’s vehicles drives 15,000 miles a year. With this increased mpg (from 8 mpg to 14 mpg)  the fleet could see fuel cost savings of $3,008 and 804 gallons of diesel fuel displaced.

What Influences Consumer Vehicle Purchasing Decisions?

August 21, 2014 in Alternative Fuel Vehicles, Fuel Economy, Hybrid Vehicles, Uncategorized

A recent consumer survey by the Fuels Institute, a non-partisan think tank founded by the National Association of Convenience Stores, found that for consumers, fuel economy is the largest deciding factor when it comes to buying gasoline or alternative fuel vehicles (AFVs).  Additionally, the cost of the vehicle plays a huge role in a consumer’s purchasing decision.

In regards to gasoline vehicle purchases, 84 percent of consumers said that fuel economy was the most important consideration, while 84 percent said that the cost of the vehicle was a key factor in the type of vehicle they purchase.

Looking at AFVs the Fuels Institute found that 80 percent of survey respondents said fuel economy was the main consideration. The fact that AFVs are better for the environment was important to 52 respondents. Of the AFV options 84 percent of respondents chose hybrids. There was an increased interest in electric vehicles from previous surveys (55 percent in 2014 compared to 37 percent in 2012).

Fleet Transition Blueprint: Natural Gas

July 24, 2014 in Alternative Fuel Vehicles, Alternative Fuels, Clean Air, Compressed Natural Gas (CNG), Fleets

While listing the benefits of transitioning a fleet to natural gas is easy, actually going through with a fleet conversion requires thorough research and analysis.  For those fleet managers seeking to move from gasoline to a cleaner fuel source like natural gas, the task may at first seem overwhelming.

If you are a manager considering transitioning your medium-duty fleet to natural gas, Work Truck Magazine recently published an article that will provide advice and clarify the process.  In an attempt to answer many of the common questions that come along with natural gas fleet conversion (i.e. What is involved with acquiring natural gas trucks? What should fleet managers expect with order logistics and delivery times? What are the factors to consider with fueling and service infrastructure?), Work Truck spoke with experts at Clean Energy, Freightliner, Cummins Westport, GE Capital Fleet Services, and Ryder to get their advice on these questions and more.

The experts provide sound advice on a number of issues:

On deciding whether the investment makes business sense:

“One of the key drivers is fuel use,” said Jeff Campbell, director of marketing for Cummins Westport Inc., which manufactures dedicated natural gas engines as a factory-direct option for several truck and bus OEMs (Original Equipment Manufacturer). “The higher the fuel use — in terms of both miles and engine hours — the better the business case.”

On deciding whether CNG or LNG is most suitable for your fleet:

“LNG is best suited for high-mileage applications where the fuel is consumed more quickly so that the fleet is not exposed to fuel venting (a characteristic of LNG),” said Perry of Ryder. “LNG fueling infrastructure is more limited than CNG, which also has an impact on the applications that can be supported. CNG is much more widely available and provides a lower cost per diesel gallon equivalent and overall operating costs under current conditions.”

On acquisition logistics:

“The availability of factory-converted natural gas trucks is limited and thus the fleet’s OEM [purchase] agreements will drive some of the decision,” said Ken Gillies, manager of truck purchasing and engineering for GE Capital Fleet Services. “Where possible, the factory-converted vehicles tend to increase customer confidence in the vehicle’s overall performance.”

On creating a fueling strategy:

If a fleet is one where trucks “return-to-base” at the end of each shift, private onsite fueling might be a practical option.

“When trucks come home every night, the drivers can park the vehicles in the yard, snap on the CNG nozzle hooked to a time-fill station, and then walk away,” said Peter Grace, senior vice president, sales and finance, Clean Energy Fuels Corporation, a provider of natural gas fuel for transportation in North America.

Finally, on maintaining natural gas vehicles:

“Fleet managers must look at what sort of modifications they need to do to their garage or service bays to ensure their shop complies with government standards for working with natural gas vehicles,” said Grace. “The ventilation has to meet certain standards and the heating systems have to be modified because if there is a gas leak, that can create a fire hazard.”
