Conservative estimates show enough natural gas, worldwide, to last your generation and that
of your children, and their children too. Planning beyond 3 generations is a waste of time.

The sky is falling.

This, plus a tank, (sold separately) is all you need to convert your car to natural gas.

No, there are 10 commercial stations where I live. Not super convenient, but doable, especially
if you think crude is going away. That is what you think, right.......

Posted January 1.
$this->bbcode_second_pass_quote('pstarr', 'H')ow would you create the necessary NG infrastructure for all regional transport, and not just urban areas currently supplied with dense NG supply lines? What is your solution to the costly energy overhead required to compress and recompress NG during fillups and for remote transport? It seems this is an unsurmountable problem ..

And just a bump from a couple years ago, here's some pics of a CNG station I took near me. Notice how technologically complex it is, obviously it's prohibitively expensive (which, after all, is why it was built!), and in fact it's such an ordeal to build the things only the folks in Pakistan have the technology, money and know-how to construct the things on a large scale!
$this->bbcode_second_pass_quote('OilFinder2', 'B')TW, I recently took a little trip to the local CNG station near me in Everett, Washington to take some pics. This is right off I-5. Handy and convenient to loads of suburban areas.

Overview


Instructions on how to use the pump


You get your choice of 3000 psi . . .


. . . or 3600 psi


They even take Visa, MasterCard and Discover!


Close-up of an actual pump thingy. Pretty simple-looking device.


Behind the pumping area was a concrete enclosure which contained some mechanicals. This was next to the enclosure. I went up and read the label on this thing but I forget what it said it was.


Peeking through one side of the concrete enclosure. Dunno what this was.


And peeking through the other side of the enclosure, I think these were the tanks holding the natural gas.

What a great idea, lets wastefully use another limited fossil fuel resource by burning it in inefficient ICE vehicles instead of more efficiently using it to generate electricity to charge EV's, and let's spend a whole crapload of money to do so. Cool beans, we have a lot of NG to waste anyway. Oh wait, maybe not:

It's widely known the electric grid cannot support a large fleet of ev's . If gasoline becomes unaffordable, large amounts of capital will need to be spent on infastructure, be it electric
or NG.

[JRP3]

Widely known by who? People who don't know the capacity of the grid?

Natural gas can be used in all classes of vehicles - motorcycles, cars, vans, trucks, buses, lift trucks, locomotives, even ships and ferries. Natural gas can be used either by converting an existing gasoline or diesel engine, or by using a purpose built natural gas engine.

Benefits of natural gas vehicles include:

Reduced particulate and NOx (Nitrogen Oxides) emissions
Reduced greenhouse gas emissions
Widespread availability of natural gas
Lower cost
Can be derived from renewable sources (biogas)
Technically proven
Available now
Can be used in all vehicle classes
Minimal processing or refining requirements
Safer than most liquid fuels
Can be refueled at home or workplace
Noise reductions of as much as 50%
Reduced engine wear
and more...

With these benefits, its easy to see why natural gas vehicle (NGV) numbers have more than doubled in the last 5 years alone. There are currently more than 12 million NGVs worldwide (October 2010) and NGV Global (IANGV) is projecting that this will increase at least ten-fold, to 50 million vehicles by 2020.

Why do so many of these "rah rah" posts come from people who have 1-5 total posts. It makes them sound like astroturfers.

[JRP3]

Indeed. That post sounds like an NG industry PR piece. The energy wasted in compressing, piping, and compressing further to fill a tank would propel an EV for many miles. A home fill station uses over 6kwh's to pump 100 miles of range onto a CNG vehicle tank, which doesn't include the energy used at the main distribution station in the first place.
