US Wants Natural Gas As Major Auto Fuel Option

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.'"

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.

Conversion Costs vs Recovery Time

[JamJam]

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

- 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

First Off, Listen to Chris Martenson

If you want to know the future of energy, listen to this Chris Martenson lecture, I believe scary times are ahead:

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

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

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.
