I would like you to meet Tim Boyle, he is one of the most NGV passionate professionals that I’ve ever met. At the current time he is the Director of International Sales & Business Development at Angi Energy Systems

Since the 70’s he has been working with CNG. At that point, the challenge was trying to figure out the best technology to fill a vehicle. After that the troubles were in harmonizing the standards and learning from previous experiences

Took a lot of effort and a really good safety record, and he recalls joining CSA standards organisation as one of the greatest steps in achieving this harmonization.

Angi produces High Quality NGV Solutions, taking an holistic look and using the latest fueling technology to give Angi an advantage over its competitors. The first thing you’ll notice is that Angi has a lot of proud on customer service, and its approach, where the most important factor is to provide value even before expecting anything in exchange.

When we talk about the industry evolution we recognized aspects as the advances on temperature compensation, and how the first compensation was done considering only ambient temperature since the early 80’s before electronic dispensing.

GTI algorithm, which is a Gas Technology Institute developed & patented technology and considers correcting for pressure changes due to temp changes in the gas, and Heat of compression, meaning that Pressure rise causes temp in cylinder to rise quickly (makes fast-filling difficult). Tha algorithm was developed in the mid-1990s

Angi Algorithm, is based not only on ambient temperature and heat of compression, but several other factors that we discuss on this episode.

Compression equipment technology all over the industry have remained essentially the same for many years, but what has improved the most has been in materials. For instance, there have been improvements on ring composites or valve materials like the discs and springs which allow mechanical components to last a lot longer impacting directly on the units availability.

On the other hand when it comes to the design of the compressors, nothing has changed. But while designing CNG stations we got two great pieces of advice to share coming out if this conversation. The first one is to understand that filtration at the inlet of natural gas is very important. Vapor levels are important to have controlled as an insurance policy. There are sites that operate without dryers, and they could go many years, but sometimes the dryers are a must, you don’t know when it’s going to it you. Specifically Tim mentioned that in México one single dryer lowered operating costs of a CNG station around 17% after it was installed. In some cases a dryer without regeneration capabilities would do the trick with a really low investment.

Secondly, while designing a CNG station, we shouldn’t underestimate the correct pipe sizing. It’s one of the biggest mistakes that Tim founds very often. A wrong selection would actually reduce the flow performance. That’s why it’s so important to consider future growth and peak hours on every calculation. Tim’s concerns are to have the proper materials to assure flow more than only ensuring velocity, so properly sizing the pipe is critical and considerations on the fueling strategies need to be considered. One size fits all design mentality doesn’t allow for optimization or control of cost, and considering first in first out filling strategies is also key to your station.

We discussed RNG and how it’s currently happening around the world. It has a very strong position if you want to consider the environment. It’s renewable and using them with heavy-duty near-zero engine the emissions results are incomparable. Far better than electric In California, ARB ranks it as the lowest carbon-intensive fuel. 

Angi have used their Biogas product line to bare on the RNG marketplace, gathering gas at really low pressure with rotary units (screw type) in a booster type arrangement for example, to put it back to the pressure line, or even fill trailers.

Currently RNG is moving forward in the United States as a policy strategy and government mandate, with good incentives in place. The RNG credits and subsidies is collaborating with market trends.

Right now is so cheap to get methane out of the ground that it’s the best source. But the cleanest solution would be to use Biogas. And Biogas is actually Hydrogen, we’ll be able to make Biogas cheaper than what it takes to strip Hydrogen.

Angi has also developed integrated compression solutions for a long time. Those are targeted to small growing stations markets, like fleet owners, Its worth to take a look to its product

The best part of the interview was its closure, and I will leave it in Tim’s voice:

Sustainabilty trends. Sustainability will eventually be the driving force for all of this. Our earth makes methane, every day. The best alternative is to capture it and use it in vehicles. I don’t care if it comes from the bottom of the ocean, from the ground, or from renewable sources.

Stay passionate. NGVs are electric vehicles, when there’s electricity to compress the gas in a usable form. NGVs are hydrogen vehicles as there are 4 Hydrogen atoms and 1 Carbon atom in every methane molecule. And if you’re in the industry, drive an NGV, practice what you preach and we could do this together.

It was a pleasure to have you Tim.
