Have an application requiring pipeline quality gas where there is no utility available?  Compressed Natural Gas (CNG) virtual pipeline tube trailers, or portable CNG cylinder containers of various types, are a viable way to provide natural gas fuel for a multitude of applications such as residential utility (primary or backup), commercial utility, electric generation (powering natural gas generators), vehicle fueling and a host of other uses.

CNG allows a large amount of natural gas to be stored in a relatively modest footprint. These storage containers can be trailer-able for ease of swapping a full container for an empty container (think propane tank exchange cages you likely use when your grill shuts off in the middle of a cookout).

The key then is “decanting” the CNG from the container and reducing the pressure to that required for the specific application. And, to add a little more detail, it’s important to be able to continue the decanting, while holding the application-required pressure, until the storage container is as empty as possible. Nobody wants to swap put and return for refill a container that has a bunch of gas left in it. That’s a large part of where InsightFuel comes in. In addition to our involvement in CNG fueling facilities and NGV fuel line system components, we manufacture Decant and Pressure Reduction Units (PRU) designed and sized for various levels of application requirements.


              Just as an aside, when you’re at the ACT show (or just call him), hunt down Jeff King and ask him to tell you the real story of the Hospital using virtual pipeline provided natural gas, and how far down the storage cylinder PSI was able to be decanted while the replacement cylinder trailer was overcoming a traffic delay to be swapped for the outgoing container. It’s also a good example of the “turns” that are achieved when a virtual pipeline system has been tuned well.


Want to take our case to a further, more clean energy conscious, big picture application?

Let’s talk Renewable Natural Gas. No, not Saturday morning after a Chipotle binge Friday night. I’m talking captured landfill or biodigester methane processed into clean natural gas, compressed and loaded onto virtual pipeline trailers or containers (see the figure below).

From that point, many things can happen and, the more of them that can be made to happen, the better the ROI and more economical the CNG becomes as a fuel. Landfill/Refuse companies can use the CNG to fuel their own vehicles. They can generate their own electricity using the natural gas processed from their renewable gas (and/or natural gas that may be available as a result of wells drilled on their property). Public CNG dispensers can be incorporated resulting in a revenue stream or possibly taking advantage of available subsidies. As described earlier, virtual pipeline containers can provide CNG to other applications and, should there be remaining, unallocated amounts of natural gas, sending it to the utility grid may be an option.

The virtual pipeline enables gas to be brought to locations that would otherwise not have access. This can be especially beneficial in short-term temporary solutions as well as remote locations.

Bottom line, InsightFuel can help

Whether with fueling station construction materials and services, mechanical construction & general contracting services, or products to decant and reduce pressure, wherever the gas molecules travel, InsightFuel can help.

You need to get CNG into your fleet vehicles?…InsightFuel can do that!

Whether you’re putting in a new CNG station (if you are, we hopefully are helping you with some aspect of that) or extending your fueling line, consider calling us for help with the time fill posts and fueling hose assemblies. We have standard designs for in-ground, ground level pad, bollard, k-rail and side-bolt mounting that fit most every application.

These post and hose assemblies can be provided fully assembled and plumbed, partially assembled and plumbed, or as complete kits for field assembly. How they have to get there, who is going to install them (we’re happy to help), and how much time is allotted for the field work can influence those decisions.

Meeting Customer Expectations

Your Contractors and Suppliers are Your Business as far as Your Customer in Concerned

For me, when I eat at a restaurant, the waitress or waiter is the restaurant. The fella that takes care of all of my lawn care needs is the lawn care company. And the garden center where I buy my trees and shrubs is the grower of the trees and shrubs that I bought. If something goes poorly with my meal because of the service, the restaurant could fall off my approved list. If my grass gets burned out because the technician set the equipment incorrectly, I may be looking for a new lawn care company. If the trees and shrubs die because they were of poor quality or diseased, I’m likely buying my shrubbery elsewhere.

So here’s my point… The quality and delivery of the materials you provide to your customer must meet the expectations of that customer. The quality and timeliness of the work done by the subcontractors you hire must meet the customer’s expectations. The people who are employees of your company and who are making direct contact with your customers must meet the expectations of the customer.

As an aside, please note my use of the phrase “meet the customer’s expectations” instead of “exceed the customer’s expectations”. Of course I want my customers to be thrilled. Through speaking with our customers about their experiences with suppliers and contractors, I have found that they tend to set their expectations high in comparison to what they will accept. So, meeting those expectations means I am not pricing my product or service higher than what my customer is willing to pay, and my customer is thrilled because their expectation was met. Okay, back to my point.

Here are 4 ways to stay on your customer’s preferred supplier list:

Bringing Lean Concepts to CNG Fueling Station Construction

Look for the 'Bright star in the dark night'.

Look for the ‘Bright star in the dark night’.

Let me start by stating what is obvious to any companies that are operating in the CNG-for- Transportation industry in North America…it’s a bear.

As we at InsightFuel begin the process of setting our course for the next 1-3 years, we find ourselves using creative business planning discussion phrases like “looking for the bright stars in the dark night” and one that our owner, Jeff, was recently introduced to, “Strategy under uncertainty”.

Although uncertainty abounds in our industry right now, one thing I am certain about is that these times call for extraordinary execution in planning, designing and operations. No one is carrying underutilized resources. Nobody has “extra” money (you know…like my kids always used to ask me for when they were young).  As well, programs and projects cannot have unexpected cost overruns and lengthy schedule delays. We’re all “Leaned-up” just to protect our businesses.  It’s for those reasons that Lean concepts have a clear place in the construction of CNG fueling stations.

Now, I have to come clean on one thing before I continue pronouncing the value of Lean concepts… I hate (okay Mom, I strongly dislike) Lean terminology. All the terms like “Muda”, “Heijunka”, “Kaizen”, “Poka-Yoke” and the like irritate me and so, I will not be using any of those in describing opportunities to improve execution.

Below are four ways to improve project execution:

Station Mid-life Crisis

Abandoned gas station.

Is your station having a mid-life crisis?

Many are, as they reach their service midlife.

Stations built 10-15 years ago were designed with the materials available at the time.  This means smaller diameter tubes, less efficient gas flow, and slower filling rates.

Standards have evolved since then as well.  Current standards can be easily incorporated during a station upgrade.

InsightFuel can upgrade and repair your CNG fueling station in just a matter of days by the following process.

Maintain Coalescing Filters to Prevent Poor Engine Performance


Extensive sludge discharge shown in the photo below the coalescing filter indicates it is poorly maintained

There is so much information available about selecting the right coalescing filter type and size. You can read for hours about how coalescing filters work and where to place them in order to reach the desired outcome for the oil carryover and cleanliness in high pressure CNG fuel lines.  Coalescing filters are positioned in multiple locations along the fueling station CNG lines, in the fuel dispensers and in the CNG vehicle high pressure fuel system lines.  The specification sheets for coalescing filters are full of details including the oil carryover Parts Per Million weight (PPMw) and micron size of the particles that will be trapped.
