Natural Gas Vehicles: Long Road Ahead

High Gas Prices Provide Push

Ken Silverstein | Mar 06, 2012


It’s no secret that natural gas is driving American energy policy. But the fuel has a long way to go if it is to actually drive the country’s transportation policy.

With gasoline prices nearing $4 a gallon, people are clamoring for relief. More drilling is one answer. But so too is shifting over to natural gas to move cars and trucks. There’s plenty of it in the ground, especially with newer drilling technologies that can access the once hard-to-get shale gas. While that obstacle has been overcome, others remain standing: The lack of fueling stations and the relative high cost of a natural gas vehicle compared with a conventional one.

Proponents of the idea say that compressed natural gas used for cars, buses and light trucks is about one-third the cost of gasoline. Right now there are about 110,000 natural gas vehicles on the road in the United States, nearly all of which are part of fleets.

“Every day we are sending $1 billion outside the country because of our addiction to oil,” said Richard Kolodziej, president of Natural Gas Vehicles for America. “We want Americans to know that there is an alternative, namely accelerating the use of domestic natural gas in vehicles instead of gasoline and diesel.”

The association is backing a bill before Congress called the Natural Gas Act, which  would provide significant subsidies to heavy truck fleets as well as commercial vehicles if they convert from a traditional combustion engine to one that could also burn natural gas. The measure has bipartisan support in both chambers.

The natural gas vehicle group says that the benefits would outweigh the costs, noting that trucks could run 650 miles before they would have to re-fill, which would reduce the level of harmful emissions as well as displace gasoline usage -- petroleum that is more-than-likely coming from abroad.

Opponents of the measure, conversely, are arguing that Congress has no special talent when it comes to deciding winners and losers. Currently, hybrid vehicles that run on both electricity and gasoline are popular while all-electric vehicles are trying to make headway. In the distant future, there’s hydrogen-powered cars that would have no emissions.

"When it comes to messed-up energy policy, technology mandates and subsidies are the problem, they're not the solution," says Ken Green, scholar at the American Enterprise Institute. "The knowledge of what works in markets is spread among the millions of people who make daily decisions on how they use energy: It does not reside in the heads of a few politicians, bureaucrats, or political appointees."

Government Role

At the same time, manufacturers and chemical makers are concerned that an increased demand for natural gas would drive up their energy costs. That would make them less competitive. The oil companies, meanwhile, also have a stake in the process. While some accuse them of blocking such progress, they are saying that they are willing suppliers of both oil and natural gas.

The reality is that government is involved in the energy business, and it always has been. When President Obama sets a goal of reducing the level of foreign oil imports by one-third over the next decade, he has to develop a comprehensive strategy. Part of that involves raising fuel efficiency standards. And part of that is trying to encourage the shift to cleaner vehicles through the use of incentives.

The federal government, the president says, will lead by example: It operates more than 600,000 fleet vehicles, some of which have already been converted to hybrids. But the president said that he will direct all federal agencies to start purchasing alternatively-fueled vehicles by 2015.

Obviously, a lot of work needs to be done. For starters, the infrastructure to support those natural gas-fired vehicles is not pervasive. Only 1,000-1,500 filling stations exist across the country, which makes driving long distances impractical. Beyond that, the tanks hold less fuel while consumers don’t have a lot of product choices: The Honda Civic, and just this week GM said it would deliver bi-fuel smaller trucks that run on both compressed natural gas and gasoline.

Transit buses now account for about 62 percent of all vehicles that use compressed natural gas, says the natural gas association. But it will be the heavy trucking fleets that set a potential trend as they are the ones burning the most fuel and spending the most money to do so. That’s why Congress would first target those 18-wheelers, which would need their engines modified. 

Those trucks would run on liquefied natural gas (LNG), as opposed to compressed natural gas. But LNG trucks cost double that of standard diesel trucks, says American Trucking Associations Chief Executive Bill Graves, who has testified before Congress on this issue. But the potential savings is huge, he adds, which is why his members are pushing lawmakers to pass the Natural Gas Act.

“Congress should enact natural gas vehicle tax credits to offset the significant cost differential between diesel trucks and trucks that operate on LNG,” he says. “This could facilitate the economies of scale in production of these heavy trucks to bring the initial costs down.”

Natural gas vehicles have a long road ahead of them. But if they are to find favor in the market, now is the time.

Gasoline price are rapidly increases, due to which day by day common people were suffering from different types problems. Therefore the demands of electric cars are rapidly increases to beat natural gas price; due to oil addiction we have found a huge up and down fall in the economy. So it's better to improve the use of electric cars.

Day by day fuel price increases rapidly; therefore it directly or indirectly affects the current economic of the country. So instead of fuel vehicle; we should used to prefer electric vehicles. To provide better mileage and better performance to our vehicles, we should take the help of better fuel efficiency vehicles.

This is quite disturbing and very worried thing for people using fuel vehicles. The price of fuels like: Diesel, Petrol, Gasoline etc are increasing so much these days. People now unable to maintain personal vehicles due to only the fuel reason. High fuel price and Gasoline make to think people  for any alternatives. Gasoline price is also so high and for that reason people want to use Natural gas as fuel for the vehicles. Mini Cooper Repair Simi valley

NGV's - The Long Road Ahead

NGV engine technology has been available for decades, and is continuously being improved. NG is an excellent fuel when used in engines designed and optimized to operate on it; however it is a compromise when utilized in lower compression gasoline engines.

The greatest impediment to large scale adoption is still on-board storage. CNG tanks will always take up too much of the passenger/cargo space within the typical car and truck. LNG has a greater energy density, however, as the insulated tanks are un-pressurized, some methane is continuously vented, which presents a potentially dangerous situation within an enclosed area.

Single shift truck and bus fleets can take advantage of greater chassis and roof areas for locating CNG fuel tanks. Overnight slow fill ensures that the tanks are full for the next day's operations. Unfortunately, fast fill systems leave the tanks at only 80% of capacity due to the effect of adiabatic heating during the compression that occurs during the fill cycle. This may or may not be an issue to the fleet owner.

The market is the best determinant of the success or failure of NGVs. If these systems provide the utility, range, reliability and least cost of operation desired by the end user, sales of factory equipped and/or aftermarket conversions will rise.

Natural Gas and Transportation Fuels


Natural gas for vehicles faces huge (expensive?) infrastructure issues.   And I believe storing large quantities of compressed natural gas is more dangerous that storing gasoline, e.g. the Oakland accident.   So I would expect big safety / regulatory issues with this approach.


The suggestion I have made before is to feed natural gas as a hydrogen additive to convert heavy crude to lighter fuels, e.g.  gasoline and aviation fuels.  This seems to me a lower cost, lower risk approach that gets natural gas into many, many more petroleum consuming applications quickly.


Note, the price of oil / gasoline is unrelated to all of this.  Oil is sold on worldwide markets; the worldwide price is assigned by oil companies to every barrel of oil, even those produced and consumed in the US; and the price paid at the gas pump is and will always be based on the worldwide price of oil.  So while more domestic production will have wonderful benefits to balance-or-trade, risk of an embargo, and safe shipping concerns, it will have minimal impact on price.  The only solution is to take pricing out of the hands of private industry, i.e. nationalize the US oil industry.   That is why Venezuela does not have $4/gallon gasoline.  I am not advocating that approach – but that is what it would take to bring down gasoline prices.

Natural Gas Vehicles

There should be a very simple and organic growth pattern for natural gas vehicle use. Local fleets of public and private trucks and buses should open their natural gas vehicle fueling stations to public use for a growing fleet of private CNG owners. Cummins and Peterbilt are introducing natural gas 20 liter engines next year. Truck stops will need to meet their needs. Individuals can compress their own natural gas at home also. Natural gas pipelines blanket almost all of the USA and Canada. Fuel at one third cost should be enough motivation for any individual or corporation. Everyone seems to want government help on everything. Tax credits might be a good idea, but leadership is what is most lacking. Entrepreneurs can convert existing small vehicles for about $4,000. Manufacturers are charging a lot more. All the equipment and technology is readily available worldwide. This is not brain surgery. Other countries have already done all of this.
