One thing I don't understand is this hoopla about CNG distribution. From what I read, installing a contraption called Phill at home lets you fill up at home. So, if you're traveling away from home, use gasoline. Until gas stations see they can offer and sell you GNG.]]> http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-217991 217991 Wed, 30 Jul 2008 00:17:31 -0400
Lawyers have been a plague since the days of the hanging gardens of Babylon. Irrigation kept that empire going until the necessity of maintaining the canals ceased to be recognized.

The big difference between a steam powered turbine and an internal combustion engine arises from the heat required to boil water, about half the total heat supplied in the boilers. The result is extraction of about 25 to 30% of the thermal energy as motive power; an internal combustion energy delivers about 40% with gasoline to about 55-60% with diesel fuel. The waste heat in the latter goes out the exhaust pipe.

I use the Energy Information Agency of Dept of Energy to follow crude usage. Refinery inputs are 15 million barrels a day (BOD), of which two thirds are imported, with most of the imports from the closest producers. Of the 5 MBOD produced domestically, about 20% comes from offshore oil in the Gulf.

LNG is a blend of natural gas that can be liquefied at moderate pressure. It does not require a super stout vessel for containment. Domestic gas, supplied by natural gas utilities tapping into the pipeline streams, is predominantly methane with a few percent of ethane and propane; it can only be liquified at cryogenic temperatures, or it can be compressed and held in stout vessels. Anyone familiar with oxygen systems may be aware of the ability to store liquid oxygen in a cryogenic container at nominal temperature. There are efforts being made to ship liquified methane from gas wells to existng pipelines, in cryogenic trailers, built like the liquid oxygen, nitrogen and hydrogen tankers, as opposed to building new gathering pipelines to the nearest major pipeline.

Upshot here is that cryogenic storage of liquid methane may be a practical solution for fueling a fleet of natural gas driven vehicles. I might add that methane from coal, with basically no ethane or larger molecules, could also be tapped as a source for liquid methane.]]> http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-217720 217720 Tue, 29 Jul 2008 16:16:33 -0400
By the way, Shaw Group just announced they are building 4 westinghouse produced nukes in China and have them producing power in 6 years.

So Obama hasn't a chance in Montana. But look at NH, which still boasts "Live Free or Die" on their license plates, and Nevada, where gambling and gold mining are their major industries. Obama is running even in these states, and could easily carry either or both of them in November.

So, the nation's getting Bluer and Bluer. Makes me Blue, too!!

As societies mature, they lose their economic zeal. A natural occurrence, perhaps.

Sorry, didn't mean to. They buttress the point EXACTLY. They also support the notion our country is entering another FDR era already.

I read the article by David Hughes you referred to. As simply another "inconvenient truth," he conveniently OMITS mentioning the Barnett, Marcellus and Haynesville gas finds, the THREE LARGEST in our nation's history. PLEASE, wake up, man! If you don't, I can assure you the Greens have a plan for you, and you won't like it!]]> http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-216455 216455 Mon, 28 Jul 2008 10:36:43 -0400 http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-216419 216419 Mon, 28 Jul 2008 10:17:51 -0400 http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-216412 216412 Mon, 28 Jul 2008 10:13:58 -0400 http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-216410 216410 Mon, 28 Jul 2008 10:06:06 -0400
Pickens owns a GX by the way, along with a "Phill," which is a device that refills CNG vehicles from NG in your HOME. So if you have access to NG, you can use it with any of the above vehicles to run on CNG today, or you can easily convert your present car or truck to do so.

This is not to say we shouldn't explore for more domestic oil and gas. Of course we should. Our so-called energy crisis is only a lack of will to GET WITH IT, then, and end OPEC's (and the Democrat's and Green's) control of our economy and way of life!

It is unclear that electrical utilities will be able to handle the load of PHEVs.

And about lawyers.

Let's discuss visibility aka viz.

Contact all the papers, letters to the editor, call the investigative reporters.

This may not work. But this is true

These bottom feeders hate visibility.

Q What's the difference between a lawyer and a carp?
A One is a slimy, bottom-feeding, mud-sucking scavenger. The other is a fish.

What i don't understand is why the USA has their head up their ass still .

Natural gas increases will have to come from unconventional sources, such as shale. That's the big one right now. But here again, the limitations are a heck of alot of water usage. Empasis on "heck of alot"
Enviro hawks will probably stop alot of unconventional gas recovery as well. Like it or not, we still need more domestically produced oil, which ironically, has the lowest enviro footprint if conventionally produced.of all the natural hydro carbons.
But the enviro nuts can't or won't talk about that.

for confirmation of water usage in shale and tight sands gas extraction see Argonne National Labs Report on same, either late last year or early this.]]> http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-215830 215830 Sun, 27 Jul 2008 15:03:28 -0400
Isn't that actually 20+ MBD? Is 15 just for transportation, or ...?]]> http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-215788 215788 Sun, 27 Jul 2008 14:08:00 -0400
Go do a heat balance on the electrical power generating plants using coal, gas, oil and then do the same for hydro, solar, wind, geo etc.:

100% btu's in fuel = 40% up stack as waste heat + 30% converted to electricity via HP steam + 30% waste heat in LP steam (which is recovered in co-generation plants).

With no co-generation or downstream use of the LP steam, 70% of the input energy is lost as waste heat.

Solar on the other hand converts 10-25% of the sun's free, readily available, forever energy at basically no waste: it's starting point is the same as the 30% converted to electricity in the above equation.
We've already eliminated 70% of the hydrocarbon energy losses.

If the electrical T&D losses are then as high as 10%, they're 3% of the incoming btu's to a hydrocarbon burning plant. End user losses detract from that as well.

Now you go do a heat balance on a NG powered vehicle to check your "should"; and by the way, compare it to solar generated electircy (or wind) - and then send it to Boone.]]> http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-215748 215748 Sun, 27 Jul 2008 13:32:34 -0400 http://seekingalpha.com/article/87234-the-benefits-of-shifting-to-cng-for-fuel?source=feed#comment-215715 215715 Sun, 27 Jul 2008 12:46:26 -0400
1) Nuclear is a solution - China is building 8-12 new plants; US has upwards of 15 being approved currently; don't forget France. Those that understand nuclear know that all reactors have upgraded since 3-mile Island; Chernobyl was not a commercial generating plant.

2) Even tho coal plants still waste 70% of the btu's as waste heat they are utilizing cleaner technology where desired.

3) We have not yet begun to consider hydro storage for peaking, etc., which utilizes the river feeder areas instead of the river's themselves.

4) Buning coal or crude or natural gas (CNG, LPG, etct.,,) results in 70% waste heat - loss of energy - non useful work - sure seems dumb to me. Seventy % of what we import is lost; that's like we need only 30% of the shipments!!!!!! That's like burning 70% of the money!!!!! Get it???

5) Co-generation projects up the conversion effeciency from 30% to 60%, but there is little of that in the US. Most uses are in industry process use not utility generation. No district heating in the US as in Europe.

6) Burning CNG loses 70% of the energy as waste heat, not just more than 40%.
Electrical transmission/distribution losses are less than 10%.

7) The charge/discharge inefficiencies of battery power are losses indeed, whether from coal, nuclear, gas, cng, solar, wind, tidal. You should treat end-use losses separately from the generation equation. Of course, in solar and wind, etc., we need only convert a little more of the free stuff which is pure gain. There are basically no conversion ineffeciencies (losses) associated with solar, wind, etc.,; only conversion effeciencies (which are GAIN! Not so with burning coal, oil, gas, etc.

8) When we burn CNG in vehicles, we lose 70% of the energy as waste heat; only 30% of the energy is available for useful work. Unless of course you have a waste heat recovery device providing other useful work. Your statements are confusing.

9) When effecient solid state energy conversion devices make electricity directly from waste heat, burning NG in a can (a burner, not an engine) and all the energy becomes electricity, then we will have a super hybrid. That makes sense. And when that's available, I say let's burn biofuels and still leave the gas in the ground. See???

Why would you want to burn any natural source if alternatives provide it freely, forever, readily available??

1. While electric cars sound wonderful, owing to cost and other barriers, they will only serve as "boutique" vehicles for the next
several years.

2. Nuclear power plants are a real answer, but they will take 20-30 years to build in any numbers.

3. We can (and ARE) utilize CNG (light duty) and LNG (heavy duty) to augment our fuel choices right now. Ask drivers of CNG cars (and conversions) in UT and OK if they like filling up for under $1 a gallon.

4. The rest of us can fill up at home if we have access to NG for about $1.50 until more fueling stations come on line.

5. Unlike other energy resources, the U.S. has DOUBLED its reserves of NG during the past 5 years. And MUCH more is on the way.

6. Pickens says he can build serious numbers of wind farms in just THREE YEARS to allow us to use more NG as a transportation fuel.

7. Does anyone have a BETTER idea that has a glimmer of a chance of running the gauntlet in Washington?
