Green Car Journal is preparing to announce its Green Car of the Year at the upcoming Los Angeles Auto Show in November and has officially revealed its five finalists. Among them is Chevrolet’s 2015 Impala CNG, which has a flex fuel system allowing the full-size sedan to run on both normal gasoline and compressed natural gas.
The Impala CNG is available only with a 3.6-liter V6 engine, which has been upgraded with hardened valves and valve seats to accommodate the use of CNG. The CNG tank is stored in the trunk and provides about 150 miles of range. A button on the dash enables the driver to seamlessly switch between gasoline and CNG, or the car will do it automatically once the CNG tank is fully depleted. Chevrolet says CNG is not only much friendlier to the environment than gasoline, but can provide savings of up to $1.25 a gallon.
The Impala CNG is up against some stiff competition for Green Car of the Year. The four other finalists consist of the Honda Fit, Volkswagen Golf, BMW i3 and Audi A3 TDI, all of which have much smaller engines than the Impala. The A3 recently proved it can travel 834 miles on one 13.2 gallon tank of diesel, while the Golf is available in both clean diesel and all-electric configurations.
Despite its relative size and V6 engine, the Impala offers a more innovative solution to fuel economy than the Fit or standard gasoline-powered Golf it’s up against and is the largest and most practical car in the competition, factors which may work in its favor as judges deliberate over their decision. The winner will be announced on November 20.
Yale University has added four compressed natural gas (CNG) buses to its on-campus fleet of 42 transit buses as a part of its shift to alternative fuels. Two of the buses are medium-sized, 20-passenger units built on the Ford E-450 chassis, and two are 38-passenger shuttle buses.
"Over the past several years, our operations have grown, so we are running more facilities vehicles, shuttles, nighttime safe ride cars, and special services vans," says George E. Longyear, Yale's director of fleet and housing. "While we are trying to shrink our emissions output of a larger fleet, we are looking at alternative-powered vehicles of all sizes."
He notes that CNG will play a prominent role in this shift. Yale's fleet management group is planning to purchase 13 new vehicles in the next year that are either factory-equipped with CNG systems or ready to be converted to CNG. Yale also currently has three MV-1 natural gas vehicles in its fleet.
Right now, Yale accesses fuel for its natural gas vehicles at a public-access CNG station located in West Haven, Conn. Another CNG station is scheduled to come online soon in New Haven, offering a closer option for refueling.
I had an opportunity to test drive the 2015 Chevrolet Silverado 2500 Crew Cab with the bi-fuel CNG option for a week and was very impressed. In fact, I primarily drove the pickup using CNG and was struck as to how indistinguishable it was from being powered by gasoline.
I’ve driven a number of CNG vehicles over the years and I must say this was one of the most seamless bi-fuel transitions I have experienced, segueing from CNG to gasoline and back all with a simple flip of the switch — while you are driving. This produces a very pleasant user experience and also a strong appreciation of the engineering that allows this to occur.
Also, the effortless transition from one fuel to the other will help facilitate use by fleet drivers who, in the past, were reluctant to use the bi-fuel option and switch to the alternative fuel. Not all bi-fuel systems allow drivers to manually switch fuels.
The beauty of these models is that they provide reduced CO2 emissions (compared to the gasoline engine), while continuing to deliver full-size truck utility.
The CNG option is available on all 2015 Silverado 2500HD configurations and Silverado 3500HD models with single rear wheels, along with the 2500HD double cab and crew cab models, and with 2500HD regular cab and all 3500HD models. The bi-fuel CNG option is available on standard- or long-box models in both 2WD and 4WD.
The bi-fuel CNG Silverado/Sierra 2500/3500HD uses the 6.0L Vortec V-8 with factory-installed hardened exhaust valves and intake/exhaust valve seats engineered for gaseous fuel use. As mentioned earlier, the Vortec 6.0L V-8 engine can seamlessly transition between CNG and gasoline.
However, there is a slight difference in power between CNG and gasoline. The gasoline engine produces 360 hp and 380 lb.-ft. of torque. While running on CNG, the engine produces 301 hp and 333 lb.-ft. of torque.
Besides allowing the driver to seamlessly switch fuels with the flip of a switch, the fuel system automatically switches to gasoline when the CNG tank is empty. This greatly expands the pickups driving range, which compensates for the lower power in the CNG mode. The combined 17 gasoline gallon equivalent (GGE) CNG tank and 36-gallon gasoline tank provide a range of more than 650 miles, it is very impressive.
The CNG tank is located in the pickup bed providing easy access when refueling. On the interior, the gasoline fuel gauge also doubles as the CNG fuel gauge, a very nice touch.
From a fleet maintenance perspective, the CNG fuel delivery and storage system is covered under GM’s limited warranty and is serviceable by Chevrolet and GMC dealers. Plus, all major components have GM service part numbers for broad availability.
In the CNG system, all high-pressure fuel lines are located between the frame rails, which increase vehicle safety in the event of a collision. There is a full 10-year corrosion validation, which is similarly value in Snow Belt regions. Lastly, the bi-fuel CNG Silverado/Sierra has a comprehensive five-year/100,000-mile transferable powertrain limited warranty, which is not the case for all manufacturers. All in all, I walked away really liking my experience with the truck and feeling like it will help expand CNG usage among fleet users.
Natural gas eased a bit ahead of today’s inventory report to trade at 3.96
as temperatures remained warm but traders booked profits after the
price was unable to break the $4 range. Several weather forecasts grew
notably higher, causing the early buying, analysts said. Heat causes
people to turn on air conditioning and use more gas-fired electricity,
and the pattern developing for the weekend includes some of the
strongest heat in what has been a mild season. Above-normal temperatures
should cover nearly all of the country..
The rally hasn’t been stronger because traders aren’t certain any
demand increase has staying power, analysts said. The peak season for
summer demand is nearly past, and there are signs that unseasonably cool
weather could return late next week, limiting any demand spike. There
are also signs the buying is from technical traders or short
sellers–traders who bet prices would fall–buying back in to close out
their past bets, analysts said.
The record pace of production already dropped gas prices about 20%
between mid-June and mid-July, and government forecasters said Tuesday
that trend is likely to continue. Unconventional gas from the Marcellus
shale and increased drilling in Texas are leading record production,
likely to increase 5.3% from last year, according to the Energy
Information Administration’s monthly Short-term Energy Outlook. It
expects annual growth to continue at 2.1% next year.
The agency dropped its price projections accordingly. It expects 2014
prices to average $4.46/mmBtu, down 6.5% from its July forecast. It
dropped its 2015 projection to $4.00/mmBtu, down 11% from what it
forecast a month ago.
The award for the precedent-setting ship, to be built at Qingdao Wuchuan
Heavy Industry's shipyard in northern China, is the latest example of
ABS' leadership in the gas ship sector, where the largest share of LNG
ships is presently being built to its classification standards.
"This prestigious contract is a testament to our commitment to high
quality service, technical innovation and remaining a pioneer in the
safe transport and handling of gas," said ABS Chairman and CEO
Christopher J. Wiernicki. "As society's demands continue to drive the
search for cleaner forms of energy, new methods of marine transport,
propulsion and processing for gas are being required. ABS remains
committed to being on the leading edge of that technical evolution,
supporting industry and regulators as they navigate through the
The CNG ship has been designed by China's CIMC Ocean Engineering Design & Research Institute.
ABS has long been a leader in the safe transport and handling of gas,
having classed the world's first LNG carrier, the Methane Pioneer in
1959, and subsequently responding to the evolving technology demands of
the largest and most modern units currently in service.
In China, it was the class of choice for the first ten large LNG ships
(147,000 m3 and 172,000 m3) built in the country's yards. ABS has also
worked on several CNG carrier concepts, supporting them through the
approval in principle process or to final approval.
PT PLN's inaugural CNG ship, which will be dual-classed with the
Indonesian class society Biro Klasifikasi Indonesia, will be 110 meters
in length and offer sailing speeds of 14 knots. It is designed to offer a
nominal CNG capacity of 2,200 m3 and will fly the Indonesian flag.
The ship is expected to transport natural gas from Indonesian fields in
East Java to communities on the island of Lombok, benefiting relatively
remote communities that are not economically feasible to supply by
The contract award comes just months after ABS unveiled its new Global
Gas Solutions team, a multi-disciplinary group of technical specialists
formed to respond to the rapidly escalating number of gas-related
projects, including LNG and LPG transportation, the use of LNG and LPG
as fuel and a growing number of FLNG projects.
The operator of Charleston’s compressed natural gas vehicle filling station on Tuesday celebrated the opening of its sixth station. IGS CNG Services has opened its latest CNG fueling station located near Youngstown, Ohio, along Interstate 80 in Girard. It is the sixth station the company has opened in the region in recent years. The company already operates stations in Charleston, Bridgeport and Jane Lew in West Virginia, along with two others in Dublin and Orrville in Ohio. It plans to open additional stations in Dayton and Findlay, Ohio, in the near future. IGS Energy president Scott White said the company hopes to develop a regional infrastructure that can serve businesses and individuals who choose to switch to natural gas-powered vehicles. “Our plan responds to the emerging market demand for fast, convenient refueling of CNG vehicles,” White said. “We want to create the opportunity to travel all over the region without a worry of whether you can find a location to fuel up with compressed natural gas.”
The city of Columbus, Ohio, has completed its second municipally owned compressed natural gas (CNG) refueling station, located at 2333 Morse Rd.: a facility that Columbus officials say is the largest public-access CNG station in the state.
Columbus' first CNG facility, on Morse Rd., came online in April 2012. To date, that station has pumped more than 500,000 GGE of CNG - about 40% of which has been used in non-municipal natural gas vehicles.
The new station on Morse Rd. will primarily serve the Columbus refuse fleet that is operating in the northern part of the metro, but it will also provide CNG to other city departments and the general public, according to Mayor Michael B. Coleman.
Three 250 hp compressors are on site, along with a single tower dryer with a manual on-skid regeneration package, 140,000 SCF of CNG storage, and three high-flow single-hose dispensers. All told, the station offers a fill rate of approximately 6-7 GGE per minute, allowing a CNG-powered refuse truck to refuel in five to seven minutes, on average.
The city of Columbus alone plans on having 440 natural gas vehicles in its fleet by 2020, which will represent a fuel-cost savings of approximately $1.9 million per year. A third CNG station is being targeted for the west side of Columbus, and fourth station - located downtown - is in the works.
City officials note that CNG is priced at $1.90/GGE at the Morse Rd. station.
J&J Truck Bodies & Trailers, a leading manufacturer of dump bodies, trailers, oil and gas field equipment, and custom transportation solutions, announced the completion of 11 commercial tri-axle dump bodies that will be fueled by Compressed Natural Gas (CNG).
The owner of the trucks, Michael Forte of MJF Materials located in Lindenwold, NJ, purchased the Peterbilt trucks from Hunter Peterbilt and the CNG tanks from d-HYBRID Systems. J&J technicians assisted with the installation of the d-HYBRID fuel systems prior to mounting the J&J aluminum dump bodies onto the trucks. The trucks will be used to haul sand and stone from quarries to asphalt and concrete plants in New Jersey and Pennsylvania. Forte has built a state-of-art CNG station on his property that will support his fleet.
CNG-powered trucks are becoming a viable solution for fleet managers who are looking for alternatives to costly diesel fuel, less reliance on foreign supplies, and a need for cleaner, renewable and safer source of fuel. Natural gas is readily available and plentiful in the United States, making it a cost effective option for company fleets. The boom in natural gas drilling is also providing a boost to local economies and an increase in job creation. "We expect to see more and more of the CNG configured trucks come to our facility for fuel system and dump body installations," said Mike Riggs, senior vice president of J&J Truck Bodies & Trailers. "To meet that demand, J&J has invested in employee training and capital equipment to support the increasing popularity of the natural gas option."
J&J Truck Bodies & Trailers is a division of Somerset Welding & Steel and was founded in 1958. The company also operates J&J Truck Equipment, both located in Somerset, Pa. Somerset Welding & Steel is an ISO 9001:2008 certified company, serving clients worldwide.
Westport says the California Air Resources Board (CARB) has certified model-year 2015 Ford F-250 and F-350 pickup trucks with the 6.2-liter Ford engine that are fitted with dedicated compressed natural gas (CNG) WiNG Power Systems.
The company had already received certification from the U.S. Environmental Protection Agency (EPA) for the same CNG system configurations on 2015 F-250 and F-350 trucks, as well as received CARB certification for model-year 2014 Ford F-150 pickup trucks with the 3.7-liter Ford engine and WiNG Power System.
The EPA- and CARB-certified Westport WiNG system installations performed on 2015 F-250 and F-350 Super Duty trucks are available with a 17 GGE, 23 GGE or 27 GGE CNG tank, the company says.
The conversions are conducted through Ford's Qualified Vehicle Modifier (QVM) program, whereby all Westport NGV conversions undergo the same safety testing required for Ford OEM products, and the original vehicle warranty remains intact following the conversion.
More information about Westport's bi-fuel and dedicated CNG vehicles is available here.
The world's largest chemical company has set its sights on improving natural gas vehicles.
BASF is developing materials that could increase the capacity of natural gas storage tanks by as much as 30 percent, said Raghu Gummaraju, business development manager for the company's energy storage materials division.
"We have a lot of ideas," he said.
Gummaraju was part of a panel on evolving natural gas vehicle technology Tuesday at the 2013 Energy Policy and Future of Passenger Transportation Conference sponsored by Oklahoma City University's Meinders School of Business.
He said BASF's technology has been tested only in a laboratory at this point, but the company has been working on a demonstration vehicle to help commercialize it.
The company also is looking for partners to help test the technology's performance in the field.
Gummaraju said BASF has developed a metal-organic framework that can increase the amount of gas that can be stored in a conventional storage tank. Each pellet acts as a small tank inside to regularize storage.
He said the technology also could make it possible to fill compressed natural gas tanks at a lower pressure.
