US Wants Natural Gas As Major Auto Fuel Option 377

coondoggie writes "Natural gas has never been much of an option for U.S. car drivers, and it's going to take a lot of effort by the government and auto manufacturers to make it a viable alternative to gas. But that's just what a $10 million program from the Department of Energy's advanced project development group The Advanced Research Projects Agency — Energy (ARPA-E) aims to start anyway. ARPA-E's Methane Opportunities for Vehicular Energy (MOVE) program wants to develop a system 'that could enable natural gas vehicles with on-board storage and at-home refueling with a five-year payback or upfront cost differential of $2,000, which excludes the balance of system and installation costs.'"

    Given that a significant amount (enough to have a noticeable effect on prices) of our natural gas is coming from hydraulic fracturing (fracking) this will undoubtably affect the demand for NG produced by fracking. Given that so many questions are being raised about environmental and safety concerns about the process, is this a good idea?

      CNG vehicles have been around forever, and fill up stations are somewhat common.

      Getting people used to the idea of automotive fuels OTHER than gasoline, and the infrastructures to support it is an overall good thing, regardless of the fuel source. If you can convince the populace at large that 2-3 vehicle fuel sources are commonly available and easy to use, then it's less difficult to get another fuel source (say electricity or fuel cells) into the mix.

      We'll see if there are valid problems associated with fracking. What I gather is that most of the known problems are failures to enforce regulation on parts of the industry.
    • I'm still not convinced fracking need be so bad.

      It sounds like there are ways to use non-toxic chemicals (they just choose to use toxic chemicals). The earthquake risk seems minimal. Fracking is probably better than alternative energy sources such as mountain-top removal- but not as good as green sources.

      I think currently the whole debate between fracking and not-fracking seems to be between overly sensitive tree-huggers who think we should stop all fossil fuel over night- and those in the energy industry

    • The big problem has nothing to do with that (no matter what kind of fossil fuel you use, there will always be a con for the environment)

      The biggest problem, in my view, is that when cars start demanding lots and lots of natural gas to run, the prices will skyrocket - which in turn will make using Natural Gas for any other thing extremely hard.

      This is a bad, bad, bad idea.

        Demand for natural gas is not really a major problem. Oil is at peak production and demand is predicted to skyrocket as China, India and various other countries continue to grow their middle class. So the next best (as in what we could use with *existing* technology) alternative has the same problem.

        The advantage of natural gas is really that it is a domestic source that can last for quite a while. It could be the bridge that we need to get us through the decades of research and development that solar, wind, tidal, etc still needs. It keeps the money spent on fuel in the US. That is not just jobs but national security as well.

    Toronto's transit system bought a bunch of natural gas-powered buses a decade or so ago, and they were great until the price of NG skyrocketed. Those are gone, and we now have hybrid electric ones, which seem to work just fine. NG is not a mass-market vehicle fuel.

    I remember when I visited my family in Pakistan back in 1999. My uncle had a switch under the dashboard of his car which switched the fuel source from gasoline to CNG (compressed natural gas) while he was driving, with the CNG being stored in a tank in the trunk. He'd switch to gasoline when driving around the mountains of the capital for the extra power but otherwise keep it at CNG because natural gas was cheaper. This car hadn't come with CNG - the conversion had cost a few hundred dollars (US dollars, I don't remember the price in rupees) for his 1980's model sedan.

    There a local program which describes the conversion costs and recovery time (in miles) for converting your vehicle to run on natural gas. [saskenergy.com]

    - The after market conversion leaves the existing gasoline system intact and adds the natural gas package to the vehicle. The installation of a natural gas system includes a cylinder that is mounted underneath, in the back of the truck or in the trunk of a car. One 70-litre cylinder equals 18 litres of gasoline and weighs approximately 160 pounds.

    Cost Based on a typical ½ ton truck

    $9000 - Conversion w/ 2 - 70 litre cylinders
    $1.0090 - Gasoline Pump Price per litre
    $0.4790 - Natural Gas Pump Price per Litre Equivalent of Gasoline
    $0.5300 - Savings per Litre Displaced
    $2.409 - Savings per Gallon Displaced

    15 mpg gasoline mileage
    $160.63- Savings per Thousand Miles

    56,031 miles - Miles on Natural Gas Required to Recover Cost of Conversion

    • Any 1/2 ton truck should have a reliable lifespan of at least 150,000 - 200,000 miles. So if you switch immediately after initial purchase to CNG only you should be able to pay off the conversion at least 3 times over.

        In the United States, LPG is not "natural gas". Natural Gas is mostly methane and is normally delivered through underground pipes to residences. LPG is mostly propane and is sold in tanks which are used for cooking or welding.

        LPG is nothing like natural gas. LPG can be stored as a liquid at room temperature under moderate pressure. For motor vehicle use, natural gas must be stored as a gas under extremely high pressure, or as a liquid cryogenically.

    I used to work for the local gas company. For decades they've had a compressed natural gas conversion for cars and a small compressor setup for the home at reasonable startup cost ($2,500 at the time). The range wasn't great, (for range you need LNG) but it was better than today's all electric cars and you could fuel up at home in a much shorter time than with electric. The fleet all ran on natural gas, filling up at their own company-maintained filling stations, and besides being cheaper and having lower emissions, as a collateral benefit they were getting exceptional life from the engines of their fleet vehicles.

    As I was interested in this conversion myself and only learned about it by accident, I struck up a conversation with the head of marketing asking why they weren't promoting it, since it was an existing solution that people could buy for their own vehicles if they only knew about it.

    And most importantly, in most areas the distribution network is already in place, something that Electric is currently struggling with.

    He said that the company was under pressure not to promote a consumer compressed natural gas solution for automobiles. He was unwilling to say where the pressure was coming from. I always wondered about that.

    So, in short, the solution already exists, exactly as described, and has since at least the nineties. As far as I can see, there's nothing to develop here, just remove the roadblocks to existing solutions.

    Mind you, it works best for dedicated commuter and in-town cars, because to keep the cost and complexity down, the car *only* runs on compressed natural gas, and CNG does not have the energy per volume as either LNG or gasoline. But in my opinion CNG is more practical than electric in several respects, not the least of which there are no batteries to replace/recycle.

    • I'm not convinced about the commuter-only viability. In the 90s I knew a woman driving some Chrysler sedan with a CNG conversion kit. Several times a month she would drive round trip to Las Vegas from San Diego (300 miles each way) without the need to fill up. That's far better range than any gasoline/diesel equivalent unless you have a truck with spare capacity tanks.

    • by Aguazul ( 620868 )
      It is also very common in Peru. People pay to convert their vehicles to gas and even give up trunk space for the tank, because it is so much cheaper to run. You can fill up everywhere. Not sure why the US needs a rebate system.

  • Natural gas is currently cheap largely because we don't use it. It is much harder to store and transport than oil.

    Natural gas cars tend to have half the mileage of a gasoline car. Better than electricity, but it is still less efficient energy storage than gasoline.

    Of course, it is still a fossil fuel. That means there is a limit on how much exists and also that it pollutes, though not as much as gasoline does.

    CNG or Compressed Natural Gas vehicles are quite common in India. It started out a decade ago when the big cities in India started converting buses to run on CNG instead of diesel to curb pollution. Then, taxis got converted. Now, you can get your private vehicle fitted with a CNG conversion kit or you can directly buy a CNG version of your car from the manufacturer. I haven't driven one myself, but have spoken to lots of cab drivers. Even if you ignore the environmental benefits, the running cost of CNG is less than half of diesel or gasoline.

    The other take on this is to have more power generation plants use CNG instead of coal. I find it highly inefficient to transport energy chemically instead of electrically. If you were developing software, this is how you would abstract your layers. Human beings suck at change. The only time we refactor anything in our lives is if we are forced to do it - like a war or an economic crisis or something similar.

    If you want to know the future of energy, listen to this Chris Martenson lecture, I believe scary times are ahead:
    http://www.youtube.com/watch?v=8WBiTnBwSWc [youtube.com]

    As for natural gas.... right now proven world reserves stands at stands at 191T m^3. The US has about 7T m^3, and a huge chunk of the rest is in Russia and Iran, which are not exactly friendly to us nor have we exactly been cultivating decent relationship with them. Since China is scouring the globe for energy sources, I assume they have or will get long term contracts from one or both of them.
    http://en.wikipedia.org/wiki/List_of_countries_by_natural_gas_proven_reserves [wikipedia.org]

    Our world usage last year was 168T ft^3 according to this:
    http://www.eia.gov/forecasts/ieo/nat_gas.cfm [eia.gov]

    Google tells me that is equal to 3.2T m^3.

    So at current rates, assuming 100% extraction, we have 60 years of Natural Gas. The best case at current usage for proven reserves, much of which are in hostile countries.

    The IEA predicts a 2.2% increase in demand annually. Using the rule of 70, that's a doubling time of ~32 years. That cuts down the best case scenario for Natural Gas down to 39 years, at current uses, meaning we don't start leaning on it heavily for transportation and the like.

    Now, the scientist in my top link talks about how if everyone switched over to electric cars, they would have to go from 300 generating plants to 3,000. One order of magnitude, 10x. Without doing specific calculations, perhaps we can assume that could carry over to natural gas if used extensive for personal transportation. How many years then?

    Yes, NG can be used in conjunction with oil and other energy sources and carry us for a while longer until we find a real solution.
