NGV Texas expects to convert 400 trucks, buses to run on CNG in 2015

Fury Zaidi beams with pride at the rows of big rigs, school buses and disassembled motors that fill up his sprawling warehouse.

All will be converted to either compressed natural gas vehicles or duel fuel, where they run on both CNG and diesel.

The president of Natural Gas Vehicles Texas Inc. said an estimated 400 heavy-duty vehicles will pass through the shop in 2015. A bold claim for sure but he says the demand is coming from school districts and trucking fleets across the country.

Natural gas burns cleaner, gets produced domestically, in the case of North Texas it comes from the Barnett Shale, and it's cheaper than diesel. Natural gas as a vehicle fuel is growing faster than anticipated, according to the fuel taxes the state collects.

The Dallas-based company has grown from a small 3,000-square-foot garage toa 30,000-square-foot facility and in June moved into a large 65,000-square-foot facility near Dallas Love Field.

The shop builds the CNG fuel tanks and even retools diesel engines to run on natural gas.

"We build natural gas engines here now," he said.

That involves modifying the pistons to reduce the compression ratio, adding spark plugs and rebuilding the valves on the engine heads.

Zaidi also provides maintenance on the light duty side to CNG taxis and AT&T vans and trucks.

The shop has a few demonstration vehicles that it will loan out so curious customers can take them for a test drive.

"If it make sense for them then we help them write grants and do the conversion," he said.

North Texas school districts can apply for grants to purchase CNG buses, too. The North Central Texas Council of Governments is offering $1 million in grant funding that's available to schools in Dallas-Fort Worth and surrounding counties.

NGV has two Saddle Creek Logistics big rigs that are being retrofitted this week. One will be a dedicated CNG truck while the other will be duel fuel. Saddlecreek is based in Florida but recently opened a logistics center in Fort Worth.

"If they are happy with product, and there's no reason why they won't be, they will do at least 50 of each," Zaidi said.

Saddlecreek, which hauls wine and liquor, will also buy new CNG trucks and install its own fueling station at its Fort Worth location.

Having your own CNG fueling station lowers the price per gallon equivalent to about $1 to $1.50.

If a truck does run out of CNG on the road, NGV will have a mobile fueling truck that can carry 100-gallon equivalent of natural gas.

"This will make service calls for CNG trucks," Zaidi said. "We have plenty of fueling stations but they still run out of fuel. This is a mobile service unit for CNG."

Ford F-150 to Offer Ability to Run on Compressed Natural Gas

DEARBORN, Mich. - Ford, America’s truck leader, will offer the 2014 F-150 with the ability to run on compressed natural gas, making Ford the only manufacturer with an available CNG/LPG-capable half-ton pickup.

The 2014 Ford F-150 with 3.7-liter V6 engine will be available this fall with a factory-installed, gaseous-fuel prep package that includes hardened valves, valve seats, pistons and rings so it can operate on either natural gas or gasoline through separate fuel systems.

When the 3.7-liter V6 F-150 is equipped with a CNG/LPG engine package, it is capable of achieving more than 750 miles on one tank of gas, depending on the tank size selected. The Ford F-150 averages 23 mpg on the highway.

“Businesses and fleet customers have been asking Ford to make F-150 available with CNG capability to take advantage of the fuel’s low price and clean emissions,” said Jon Coleman, Ford fleet sustainability and technology manager. “With the money saved using CNG, customers could start to see payback on their investment in as little as 24 to 36 months.”

CNG/LPG engine prep from the factory costs approximately $315 before the customer chooses a Ford Qualified Vehicle Modifier to supply fuel tanks, fuel lines and unique fuel injectors. Upfits run approximately $7,500 to $9,500 depending on fuel tank capacity.

CNG conversions can provide stability against fluctuating fuel prices as well as lower vehicle operating costs for fleet administrators. CNG sells for an average of $2.11 per gallon of gasoline equivalent, and is as low as $1 in some parts of the country, representing a significant savings over unleaded regular fuel. The national average for unleaded regular fuel is $3.66 per gallon.

2015 Impala, A Green Car Journal Green Car Of The Year Finalist 

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.

Ivy League Fleet Deploying Compressed Natural Gas Buses

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.

2015 Chevrolet Silverado 2500 Bi-Fuel CNG Pickup

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.

Forecast Natural Gas Fundamental Analysis

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.

ABS to Class the World's First CNG Ship

​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 challenges."

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 pipeline.

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.

Natural gas chain opens fueling station

​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.”

Ohio's Largest Compressed Natural Gas Station Ready For Fueling Action

​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 Completes First Fleet of CNG Trucks

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.
