CNG moves ahead on all fronts

/in , /by

The effort to substitute compressed natural gas for foreign oil in our gas tanks is moving ahead on all fronts across the country, in scores of municipal departments that are converting their fleets, in new gas stations that are opening and with entrepreneurs who are looking for ways to speed up the conversion.

Leading the pack is Clean Energy Fuels, T. Boone Pickens’ effort to put the nation’s natural gas resources to work in the transport sector. Clean Energy Fuels has targeted long-distance, heavy-duty trucks, which tend to stay on the Interstate Highway System and can be services at massive truck stops. In Pennsylvania, for instance, Clean Energy Fuels is building stations in Pittston and Pottsville that will serve trucks on heavily the traveled I-81 and I-476. They are scheduled to open later this year.

But much of Clean Energy Fuels’ real success is coming from the fleet conversion for major shipping firms that rely heavily on truck transportation. The company has had particular success with UPS. Fueling depots were recently opened in Oklahoma City and Amarillo, Texas. The carrier E.J. Madison, LLC has deployed a fleet of 20 long-haul LNG trucks that will utilize a CEF network of stations that stretches from Los Angeles to Jacksonville, Florida. Jacksonville is emerging as a hub of CEF activity as the company has opened a liquid natural gas (LNG) terminal there as well. LNG is more difficult to handle than compressed natural gas but has much greater energy density.

Rapidly expanding in Florida, CEF has just announced a grand opening of a CNG filling station that will service the Hillsborough Area Regional Transit Authority (HART), which provides public transportation throughout the Tampa metropolitan area. The opening kicks off a plan to convert HART’s entire fleet of public services buses and vans to compressed gas.

Just last week Clean Energy Fuels CEO Andrew Littlefair was in the news telling The Motley Fool that Tesla’s electric cars will not be in competition with CEF’s efforts. “Tesla and electric vehicles are really great for certain applications,” he told interviewer Josh Hall. “But hauling 80,000 pounds of cargo, natural gas is really well suited for that.”

However, even if Clean Energy Fuels doesn’t think CNG can compete with electric at the passenger-car level, others do. Last week the Wawa convenience store chain announced it will partner with South Jersey Gas to open CNG fueling stations in southern New Jersey. “Compressed natural gas gives us an opportunity to increase the convenience we offer our customers and positions us for the future as well,” Brian Schaller, vice president of fuel for Wawa told the press. “We’re excited about the growth potential.” With 600 stores on the East Coast from New Jersey to Florida, Wawa has plenty of room to grow.

Pennsylvania is becoming a hotbed of compressed gas progress as the state seeks to take advantage of the Marcellus Shale. The state has adopted a funding program to help businesses convert. One of the first to take advantage is Houston-based Waste Management, which received an $806,000 grant from the State Department of Community & Economic Development to switch 25 of its waste and recycling collection vehicles to CNG. Pennsylvania-American Water Company has also announced plans to convert its fleet with a $315,000 state grant. American Water, the largest water utility in the state, operates out of Scranton.

Nebraska is a long way from any natural gas drilling but the Uribe Refuse Services company of Lincoln has announced it will convert its entire fleet of 17 trucks to natural gas over the next few years. The first trucks were displayed in the city last week on Earth Day.

Oklahoma is a big oil-and-gas producing state and is making a major effort to convert state vehicles to natural gas. In 2011 Gov. Mary Fallin joined 15 other states in a multi-state memorandum of understanding committing them to purchase NGVs for the state fleet. The state now has 400 CNG vehicles and is pushing the federal government to convert its fleet in the state as well. Oklahoma is building CNG gas stations to match and now stands third in the nation behind California and New York.

The natural gas industry is putting its shoulder to the wheel on this effort. The American Gas Association and America’s Natural Gas Alliance (ANGA) have teamed up to sponsor “Add Natural Gas (+NG),” an effort that is encouraging entrepreneurs and mechanics to convert ordinary passenger cars already on the road to CNG. “Fleets across the country are already using natural gas vehicles to save money and reduce emissions,” says the group’s website. “However, natural gas can be used to fuel any vehicle. To demonstrate this, we worked with automotive engineers to add natural gas as a fueling option for some of the most popular vehicles on the market today.”

Performance CNG LLC is a Michigan startup that has been inspired to take up the initiative. The company recently had a hybridized 2012 Ford Mustang GT demonstrated as part of +NG’s campaign and is currently trying to raise $55,000 in capital on Indiegogo, an international crowd funding site. More than half the money would go to EPA emissions testing.

Not everyone is convinced that CNG is the way to go. Clean Energy Fuel’s stock has done poorly since January, based on investor skepticism that its market is not that big and that some liquid natural-gas based fuel – methanol of butanol – will prove easier to handl

Can the Marcellus give birth to CNG vehicles?

/in , /by

What if America had so much natural gas it didn’t know what to do with it?

Right now that’s the situation in the Marcellus Shale, the vast formation that underlies nearly all of Pennsylvania. There just isn’t enough demand for what’s available. And the same situation could be facing the entire United States in just a few years, according to speakers at the 2013 Natural Gas Utilization Conference held at the Omni William Penn Hotel in downtown Pittsburgh last week.

“Today there are 800 shut in wells in the Marcellus, waiting for an increase in price and improvements in infrastructure,” said Justin Carlson, manager of energy analytics at Bentek Energy of Colorado told the gathering. “By 2017, demand could dip below supply for the entire United States. We’re not doing enough to support growth. The market needs more users.”

Where could you find those new consumers? Virtually everyone agrees that there’s one market that is begging for greater natural gas use – the transportation sector.

Some companies are already looking for ways to do it. Last year Consol Energy Inc. and Praxair, Inc., a Connecticut-based manufacturer of industrial gases, was preparing to build a $2 billion plant to convert gas from the Marcellus into gasoline and diesel blends for use in cars and trucks. In the end, however, the economics didn’t quite work. “The project would have generated a positive rate of return but not the 12% that investors are looking for,” said Dante Bonaquist, chief scientist and corporation fellow at Praxair, who spoke at the conference. “We had to give it up.”

So absent a liquids option, most gas producers are opting for another technology – compressed natural gas. Leading the pack has been Chesapeake Energy, which set a goal to convert its entire fleet of vehicles to CNG by 2015. At the current pace it will hit the 80% mark in 2014. Last year Chesapeake’s Peake Fuel Solutions affiliate also partnered with GE to launch “CNG In A Box,” a package that compresses natural gas from a pipeline into CNG fueling stations so that small and large retailers can become vendors of natural gas. The package was introduced at the National Association of Convenience Stores 2012 annual convention.

“The 8-by-10-foot container is easy to ship and its modular design allows for plug-and-play,” said Bob Jarvis, spokesman for Chesapeake. “It makes pay-at-the-pump a familiar and secure experience.” GE already has a manufacturing plant up and running in Houston. On Sept. 17 it announced a memorandum of understanding with China’s Endurance Industries to deliver 260 CNGs In A Box to fuel China’s rapidly growing conversion to natural gas vehicles.

Last week, however, Chesapeake was forced to disband its seven-member Natural Gas Vehicle Task Force as part of an austerity-driven reorganization. But other companies may pick up the slack. “Chesapeake has been an important player in growing the natural gas vehicle market, but other companies and organizations have taken on that role now,” said Rich Kolodziej, president of advocacy group Natural Gas Vehicles for America.

Range Resources, another major player in the Marcellus, is also making an all-out effort to promote CNG vehicles. It recently closed a deal with GM to buy an entire fleet of trucks for its Pennsylvania operations. The company expects to save 40-50% of vehicle operating costs by switching from gasoline. With 180 trucks in the region, each carrying a 17-gallon tank, Range will save $3,000 each time its fleet refuels.

But is compressed natural gas the best way to go? The technology involves high-pressure tanks, both in storage and in your car or truck and involves a whole new infrastructure. Converting natural gas into methanol – a fairly simple process – would allow us to use the current infrastructure with only a few minor adjustments. Existing vehicles can be modified to use methanol for only a few hundred dollars and flex-fuel vehicles could use either methanol or traditional gasoline.

Methanol works better from the supply side as well. “The economics of methanol would have been more attractive,” said Bonaquist, of the Praxair-Consol Energy proposal that didn’t make it off the drawing boards. “The conversion and purification sections of the plant would have been less complex. It would have been particularly advantageous for smaller scale production.”

So what’s the problem? Well, unfortunately, putting methanol in your car hasn’t yet been approved by the Environmental Protection Agency. That makes it illegal. If the regulations could be changed, methanol would become a much easier route for moving the nation’s looming gas surpluses into the transportation sector. There could hardly be a more promising way of freeing ourselves from dependence on foreign oil.
