Top U.S. Energy Analyst Calls Natural Gas Storage Surplus Smoke and Mirrors

“I think the (natural) gas storage surplus is smoke-and-mirrors,” said Phil Flynn, Energy Analyst for Alaron Trading Corporation in Chicago. “It masks an underlying problem with production.” Mr. Flynn is not alone in his assessment of the natural gas market. Jim Cramer of The Street.com echoed similar thoughts. Flynn wrote in his Energy Report on Tuesday, “Lets face it the heat has melted away the veil of secrecy around the natural gas complex.” The devastating U.S. heat wave has left its mark on North America’s electricity grids, which has now reversed the downward trending price of natural gas.

The year-to-date bottom for September natural gas futures prices came on July 18th. A reversal came the following day and pricing has since climbed higher on (a) California’s heat wave, (b) natural gas inventory drawdowns and (c) near-record high or record-high electricity usage in the eastern half of the United States and parts of Canada. Also on July 18th, we published our interview with Sprott Asset Management analyst Eric Nuttall, entitled, “Zero Doubt: Natural Gas Prices Will Go Higher Again.” The markets are all about timing and the interview with a member of the Sprott Asset Management team again reminds us why they are amongst the most prescient (and successful) of North America’s money managers.

Natural gas production is declining. “The demand for natural gas continues to rise and production is failing to keep pace,” Flynn told us. “The storage surplus has given us a false sense of security.” On July 10th, James Rogers told us, “Longer term, natural gas production is declining in North America. Eric Nuttall told us, “North American natural gas production has been in decline for several years.”

Natural gas is the primary source for electricity generation. Record humidity and temperatures drive consumers to run their air conditioners on higher settings and for longer periods. In one Reuters news agency report, Ohio dairy farmers were reportedly air-conditioning their cows to keep them alive. Another heat wave passing through the United States might seriously jeopardize the country’s power grid.

The New York Times reported this past Wednesday, “Experts say demand is rising faster than the ability to meet it, which over the long run could pose the risk of both local and regional failures.” Three system operators, managing regional grids for the some of the worst-hit states, said demand for electricity set new records which eclipsed records set only two weeks earlier.

The Cape Verde Hurricane Season

Experts have begun calling this the ‘Cape Verde Hurricane Season,’ because multiple storm systems are moving westward from Africa through the Cape Verde Islands. Hurricane scientists from Europe and the United States are now in Africa studying the clusters of storms rolling off Africa’s coast. Another team is in the Caribbean. Some of the thunderstorm clusters, called ‘tropical waves,’ which form between seven and ten times per month, develop into hurricanes. Of the 60 or 70 tropical waves passing over West Africa’s Cape Verde Islands, about ten percent grow into tropical storms or hurricanes. According to the National Oceanic and Atmospheric Administration (NOAA) in Miami, these African thunderstorms account for 85 percent of all major Atlantic hurricanes.

Offshore oil and gas production in the Gulf of Mexico, which accounts for about 25 percent of U.S. production, may be shut down again this summer. There could be several hurricanes expected in the Gulf of Mexico’s hurricane season, which lasts through November 1st. Most of the devastating Atlantic hurricanes occur between mid August and early October because of the warmer water temperatures.

“Things are not back to normal in the Gulf of Mexico,” said Flynn. “Gas storage is needed as a buffer against extreme weather.” In this case, a hurricane or a series of hurricanes would be extreme weather. Flynn believes that despite ample storage the market is “easily given into the passions of weather extremes.”

In our mid July interview with Sprott’s Eric Nuttall, he leaned toward the camp which was bullish, saying, “Now is the time to load up on the (nat gas and CBM) stocks.” He recommended some of his firm’s favorites, which as he admitted at the time could trade sideways for the next two months. These included, among others, Crew Energy (TSX: CR), Canadian Spirit Resources (TSX: SPI) and Pacific Asia China Energy (TSX: PCE).

Nuttall believed there were significant opportunities in unconventional gas companies, known as coalbed methane (CBM) companies, as well as conventional gas shares. As Nuttall previously told us, “Most incremental production is coming from smaller, more expensive-to-drill, thinner economic, higher decline pools and reservoirs.”

But, Nuttall cautioned, “Timing on any natural gas investment right now is tricky.” And he added, “Although the market might be a bit sloppy for a few months, I think there are some great bargains to be had for the patient investor.”

We pursued our July interviews on the subject of natural gas based upon a luncheon meeting we had in early June with Steven Mizener, chief equities strategist for the Toronto mutual fund company, Sentry Select. He advised patience in the natural gas markets and that by the end of August, natural gas stocks might again gain favor. Phil Flynn warned of stronger drawdowns this winter, “With a colder winter and heating usage for gas, there will be a lot more drawing (of the inventories). We could have a significant depletion in storage if we have a cold winter.” Again, investors have been lulled by the ‘false sense of security’ of the perceived storage surplus. And as one wit remarked on the Motley Fool chat board, “With that inventory drawdown last week due to the heat, it appears that we may have seen the bottom in natural gas for some time to come.”

A Review of Air Compressor Manufacturers

It is no surprise that with the increase in demand for high quality air compressors, several manufacturers are continuing to perfect the quality and standards for these devices.

You can find at least a dozen very well-known and respected air compressor manufacturers. Most of these companies adhere to the strict quality and safety standards as set forth by the American Society of Mechanical Engineers (ASME). This governing body is responsible for regulating air compressors and all of their certified products will be labeled accordingly.

One of the most popular air compressor manufacturers in the United States is Sullivan-Palatek, located in Indiana. This company prides itself on creating some of the most advanced engine-driven air compressors on the market, both in terms of quality and safety. These air compressors are among the most energy-efficient available. They also offer used air compressors and air compressor rentals.

Atlas Copco Compressors Inc. is also a very well respected authority in air compressor manufacturing. Located in Massachusetts, Atlas Copco has been in business for several decades. They specialize in both portable and stationary air compressors. Their popular stationary models include lubricated, oil-free, PET, centrifugal air & gas and turbo expanders.

These three companies are just a few examples of the fine air compressor manufacturers located in the United States. With decades of experience, most of the companies that manufacture air compressors are continually striving to make them better. They are in a continual process of advancing features to make air compressors affordable, long lasting, safe, and energy-efficient. When choosing an air compressor manufacturer, you should probably choose one that has been tested and certified by the American Society of Mechanical Engineers (ASME). Many states only allow the sale of devices certified by the organization. This group has set rigorous quality and safety standards that should be applied to most air compressor models.

What’s a 22 Compressed Air Valve

Here’s information on the simplest type of air valve; the 2/2 style.

The first 2 in the 2/2 air valve refers to the number of “working” air ports that are found in the valve body. That is, the number of ports that supply air to the valve, and channel the compressed air to whatever it is that the valve is supposed to do.

Most 2/2 valves will have numbers or letters etched, cast or painted near each of their two “working” air ports. If there are numbers near the ports, the number 1 would be the supply port to bring the compressed air to that valve. Port number 2 would be the working port from which air would flow to accomplish whatever task that you wanted that valve to do.

If the port designations are letters, then port ‘A’ would be the supply port and port ‘B’ the working port.

If the 2/2 valve is to be “air operated”, that is an external air signal is to be used to shift the 2/2 valve, there will be another port. That port may not have a designation or it might say ‘12′. No, that’s not a twelve, but rather indicates that air will flow from port 1 to port 2 when an external air signal operates that valve.

The second 2 in a 2/2 air valve indicates the number of positions that the internal valve mechanism has. In this case, two. When this valve is operated or actuated, it will either open or close. At rest, that is when the external valve operator has not been activated, the internal valve mechanism will either stay open or closed.

Most 2/2 compressed air valves are classified as NC. NC stands for normally closed. This means that when the valve is not actuated, it’s normal state is closed, and compressed air cannot pass through it.

There are some applications for 2/2 valves where the flow of air through the valve when it is not being operated is desirous. A NO or normally open valve would then be selected. When this type of 2/2 valve is at rest, compressed air will flow through it, and it is only when the valve is actuated that the flow of air will stop.

All 2/2 valves will have actuators that will operate or ’shift’ the air valve.

A compressed air blow gun is a good example. On it there will be a push button or a trigger of some kind. When the button is depressed or the trigger is pulled, the compressed air will flow through the gun and out the nozzle to atmosphere. When the actuator is released, an internal spring (a secondary actuator) will shift the internal valve mechanism back, and the air will stop flowing. A compressed air blow gun contains a 2/2 NC air valve.

Some other 2/2 valve actuators are whisker switches, toggles, push buttons, palm buttons, roller cams, electric solenoids or compressed air.

2/2 valves can have detented or non-detented actuators. If the actuator is detented, this means that when the operator actuates the valve, the actuator will stay in the position selected until it is again moved by the operator. Toggle switches for air valves are often detented. You flick the toggle in one direction to actuate the valve, and it will stay actuated until you move the toggle back. The detented 2/2 valve may not have an internal spring, though with standardization of manufacture, even a detented valve may have a spring, since various kinds of actuators may be affixed to that same valve body.

Non-detented valves do contain an actuator spring, and the internal valve mechanism will “spring” back to the other position when the operator releases the primary actuator, similar to what happens when the button on a compressed air gun is released.

At ABOUT-air-compressors.com, an e-book entitled All About Air Valves - volume one - will soon be available (end August 06). If you are interested in more information about air valves, do visit the site and download a copy.

All 2/2 valves must, when operated, allow air to ultimately flow to atmosphere. If a 2/2 valve is selected to provide air to a closed tank or air vessel, then when the 2/2 valve is shifted to a closed position, the air will be trapped in the downstream line. You wouldn’t select a 2/2 valve to provide compressed air to an air actuator, for example.

The exception to this rule are inflatable bladders that contain their own integral 2/2 valves; a bicycle or vehicle tire being good examples. When you connect your 2/2 air supply valve to the tire valve, the tire valve - itself a small 2/2 valve - is actuated by the supply valve fitting, allowing compressed air to flow into the tire. When the supply valve is no longer actuated, as long as the fill fittings is attached to the tire valve, the line is pressurized. That’s why, when you pull the fill fitting away from the tire, you hear that characteristic “pssssst” as the air that’s been trapped between the two valves is vented. The tire valve will have shifted back to being closed by the air pressure inside the tire, thus preventing the compressed air in the tire from escaping back to atmosphere.

Other 2/2 compressed air valves commonly encountered are those push button valves on the handle of air tools, and the air-horns that are commonly heard at sporting events.

The air-horns were designed as distress sirens for small boat operators. The push button on the top of the gas canister is the 2/2 valve, and it’s the pressure of the compressed gas trapped in the canister that forces the valve shut (NC - normally closed) when the button is released.

I guess it’s better to hear an air horn at a football game than indicating some poor boater’s distress out on the lake; unless it’s blasting into your ear, of course!

And as always, if you have any questions, please send me a message from the contact screen at my web site.
