$this->bbcode_second_pass_quote('isgota', 'I') think you have forgotten that making oil products consumes huge quantities of energy (about 10% of the energy in a refinery). Anyway since you've asked for numbers, I'm going to give you a pair a well-to-wheels studies:

- American study (see section 4.1).

- European study (both well-to-tank and tank-to-wheels).

To sum up the results for CNG, total energy consumption is a little less than gasoline and a little more than diesel, but in both cases reduces pollution.

Precisely. In addition to that, he also conveniently forgets that the process of extracting natural gas does not require pumping as oil extraction does.

An oil pump like this uses energy. Some oil wells initially flow on their own without pumping, but most - if not all - eventually have to be pumped out.

Image

A gas, on the other hand, cannot be pumped, and once you've drilled the NG well, the gas flows out on its own.

Image

Then after it's pumped - ermm, "sucked out" - most gas requires comparatively little processing.

In many ways, natural gas is actually a superior energy source compared to oil, contrary to pstarr's misinformed opinion.

Misinformed as usual. Unconventional gas reservoirs have to be in many instances dewatered and the gas is produced at low pressures and must be pressurized to pipe line standards, before the comparatively little processing.

Dewatering doesn't take a lot of energy (most of the water just condenses, allowing you to tap the water off). I've talked about pressurizing before. The lower the pipeline pressure the less energy it costs. It's only significant if you make CNG.

Well, perhaps. First, if the dewatering isn't done properly, there can be unpleasant consequences. For example, one recent time central KY had record low temperatures (-21 F in the 90's, as I recall), the main gas line feeding Ravenna KY, (50 miles Southeast of Lexington, where my girlfriend lived, so I got the story directly), FROZE SOLID due to the water vapor in the pipe. Kind of inconvenient for the folks that had to live in a shelter that night while the repair crew enjoyed the brisk night air.

If you don't do a good job dewatering, can it cause a real issue at typical CNG pressures? Remember, folks' cars need to operate extremely reliably under all kinds of adverse weather conditions.

I'm not taking a doomer tone here - just pointing out that this issue may not be completely trivial.

What does the R/P ratio have to do with it? Do you honestly believe that the production rate will stay the same for a couple of hundred years and then stop?


Quite true. Much like current global oil production, production could go down, and suddenly we would have a thousand years of supply versus a few hundred.

The uni-directional thinking around here tends to double clutch the instant it becomes obvious that "eternal growth" is just a strawman assembled to allow Doomers to bash BAU.

The higher the pressure, the drier the gas has to be. CNG stations typically have driers. Even the Phill home refuelling unit has a built-in drier.

I think people need to realize that BAU is constantly evolving. There's really no "usual".

In the 1950s and 1960s, BAU was petroleum demand doubling every decade. During that same time period, the BAU solution to the natural gas problem was to burn the gas off. It was considered a dangerous waste product of oil production.

Now we use it generate electricity and power city buses. Some day, relatively soon, it might power a significant portion of our auto fleet.

Knee-jerk rejections of new technology because they don't fit into your preconceived notion of the world aren't helpful.

CNG is not new technology. It was used by the Italians already in the previous depression to reduce their dependance on foreign oil.

Im a bit of a doomer but I fiercely agree with that statement.

Natural gas is suitable for electricity and could be useful in rail networks, as both systems are fixed in place.

Exactly. An MP36PH-3S: 3,600 THP, static inverter HEP.

Fit one of these to Propane/NatGas. Just can't wait.

I then posted why collapse will ensue now and it won't be controlled.

Until DC is neutered and places that actually make stuff, like
Alberta, Utah, ND, ARLATEX step in. IMHO.

$this->bbcode_second_pass_quote('TheAntiDoomer', 'T')he posts denying the production of all this gas were very entertaining. We've only just begun to tap most of these plays and more are being discovered on a regular basis. Face it guys, there will be affordable n. gas for 100 years +. -Maddog


And btw, yes, affordable NatGas for a 100 years.

Now who's going to pay to retrofit 100 years of
coal/oil infrastructure. And pay with what?

Remember that NatGas is not fungible.

I can show you billions of dollars of NG infrastructure already being built, and billions of dollars of NG wells being drilled. I can also show you billions of dollars being spent on coal and oil production and transport. So why would paying for this stuff be so impossible? Huge sums of money are *already* being spent in the energy biz, including NG.

Every time someone comes up with the objection, "Where are we going to get the money to build all this?" I laugh. If we can come up with guargantuan sums of money to build things like this and this and this on a routine basis, coming up with some money to build a bit of natural gas infrastructure would be a relative piece of cake.

1) Money is energy. No energy, no money. Again that
quadrillion ($1.4 quadrillion+). In debt. Meaning money
already spent. Meaning amy money has to pay off this
debt before any more debt can be issued.

2) The five Kings are now in decline. Cantarell will be below
500k bpd this time next year.

3) Gas is not fungible. You cannot replace a gallon of
gasoline with a gallon of gas. LNG is the one fungible aspect of the NatGas business:

"Traditionally, LNG has been base loaded, but I think increasingly LNG is going to ... come to be recognized in a much different way in U.S. markets, particularly foreign LNG, because it is the one fungible aspect of the natural gas business. ... You can take a cargo that's en route from "Trinidad Tobago," which is our largest supplier of LNG today, and you can divert it en route, and you can't do that in the pipeline business. So it gives you physical ... [options], it gives you financial ... [options], and so increasingly I think we will see LNG operate in a very flexible fashion."

July 17, 2009

Telecommunications giant AT&T says that it will renovate its gasoline-powered fleet of vehicles so that they can use alternative fuels such as natural gas. Over the next five years, it will convert 8,000 of those cars. It then hopes to have 15,000 clean-burning vehicles on the road by 2019. Altogether, about 120,000 natural gas-fueled vehicles are now in operation in this country. That doesn't even cover the cash for clunkers program.
