Jalopnik Brain Farts On Natural Gas Pipelines

Photo: Sierradelta74 http://www.flickr.com/photos/sierradelta74/It's not that uncommon for a writer to make a mistake. You're in the flow of the moment, tapping out stylish bon mots with just the right balance of serious and snark and it sounds right so you don't bother to research the point and you later find out in the comments section that you made a factual error. It's usually much more than that, but an 800 word post on a car blog is not a treatise written with graduate school levels of footnotes and citations, so mistakes get made and I'm hardly blameless in that regard. Still, sometimes you gotta call a mistake a mistake, and Jalopnik made a whopper.

As part of their I Feel Gassy series on energy issues, Benjamin Preston posted Why We Aren't Driving Natural Gas Powered Cars, contrasting the current glut of natural gas in the United States (and significant new finds of recoverable gas deposits), with this country's relative paucity of natural gas powered vehicles. Much of Preston's article dealt with the controversy over fracking, since extracting gas from those new plays will most likely involve hydraulic fracturing. While I think he could have been more balanced in his selection of sources and treatment of the subject, what really jumped out at me was his categorical (and factually wrong) statement on how natural gas gets to consumers.

Ben makes the legitimate argument that there are many costs to extracting natural gas, financial and environmental, that are not immediately obvious. The extractive industries use a great deal of water and producing fossil fuel has its own carbon footprint. Preston goes on to argue that one hidden cost and environmental impact of drilling for natural gas is that America lacks pipelines to get the gas to market.

[Extracting natural gas] uses a lot of water, and with no pipeline infrastructure, transportation costs money and adds to air pollution.

When I first read that, I thought, "What do you mean, no pipeline infrastructure? There's a gas line to my furnace!" Upon second thought, though, I considered that Preston might have meant that there were no pipelines for carrying needed water to the wells. Farther down in his piece, however, Preston makes it clear that my first impression was accurate. Those increased air pollution and transportation costs are supposedly the result of needing to use tanker trucks to move the gas from the wellhead to consumers.

As it stands now, most natural gas is transported by tanker trucks — a lot of tanker trucks.

I realize that most website editors don't do a lot of fact checking, but don't any of the Jalopnik editors ever cook with gas? Do none of them have a natural gas fired furnace heating their homes? Have they never seen a natural gas well in a rural area? Does Ben Preston really think that most natural gas is transported by trucks and that we don't have an infrastructure of pipes that carry gas from the well to consumers? Does he think there's a constant stream of tanker trucks queuing up to every natural gas well in America?

Regarding our supposed lack of a pipeline infrastructure, an image search on "natural gas pipelines" yielded a variety of maps of the interstate and intrastate pipeline networks that crisscross the United States.

Sure looks like a pipeline infrastructure to me.

As for Preston's contention that "most natural gas is transported by tanker trucks", again that's simply not true. Don't take my word for it, take the word of Ed Tucker, who runs Tucker Gas Processing Equipment, which, among other services, will transport natural gas via trucks. TGPE's website explains when that makes sense:

Many sources of natural gas are shut-in and abandoned because the economics simply do not justify their development. In some cases, access to public transmission lines may be limited by distance or local geography. In other cases, the need for additional processing to bring the gas up to pipeline quality standards may be a factor. While many industrial applications can utilize gas that does not meet these strict standards, the distance to the nearest such industrial consumer may not justify the cost of laying a direct pipeline. In such cases, transporting the gas by truck may provide a solution.

When I asked TGPE what percentage of US natural gas is transported to market via trucks, Ed Tucker told me (emphasis added):

The answer would be next to none. The CNG trailers in the US are used primarily to transport gas from one place to another when they are repairing a pipeline and have to shut down a line for a few hours. Some years ago we had two small projects transporting from small gas fields. We had an inquiry from Vermont earlier this year where they wanted to substitute CNG for propane since there were no pipelines and the ratio of cost for propane was $28 per one million Btu versus pipeline gas at $2.50 per one million Btu.

Had Preston's remarks about there being no natural gas pipeline infrastructure been restricted to newly developed wells, that might have been more accurate. However, based on what Tucker told me about how little gas is actually trucked, I think it's safe to assume that the developers of any new natural gas wells include hooking them up to the existing pipeline system as part of the installation of those wells. In addition to dedicated natural gas wells, natural gas can also be a byproduct of extracting petroleum. Tucker pointed out that in the Williston Basin (under Montana, the Dakotas, and Saskatchewan), oil producers that aren't serviced by gas pipelines will flare off the natural gas they produce rather than truck it and sell it. The cost of trucking it to a processing or gas sweetening plant is just not cost effective, particularly at a time when natural gas prices are low.
