T&T Power Group’s “Powering Greenhouses 2018” conference welcomed greenhouse growers from across Southwestern Ontario to learn about and discuss eco-conscious industry practices and energy efficiencies.


What We Learned from Loran Novacek at Powering Greenhouses 2018

One of several special guest presenters at the conference was Loran Novacek, the CEO of AeriNOx, Inc. who joined us all the way from Colorado. During his presentation, Loran talked about the purpose of Selective Catalytic Reduction (SCR) technology, and why extending this technology into the greenhouse market space would be beneficial.

Key Takeaways From Conference

Loran began his presentation with a simple analogy. “For many of you, you’re probably already familiar with SCR,” he said. “If you think of some of the General Motors – the Fords, the Dodge pick-up trucks, the diesel trucks that are on the market right now, they have a DEF system – which is nothing more than an SCR system on the vehicle already.”

He continued to explain that the EPA guides and drives a lot of SCR technology. “The whole idea behind it is to really reduce overall exhaust emissions in the market space. This market space that we’re talking about now, is really an adoption of what automotive has been doing for many years – it’s just in the industrial market space it’s intended to last years – not a few thousand hours that you’d find in the automotive market where you equate it to miles rather than tens and twenties and thirty years of market space.”

Loran went on to explain the difference between a rich-burn engine and an SCR system. “Rich burns you just throw on a catalyst and you have a way to manage the air/fuel ratio”, he said. “On an SCR system it requires a re-agent, [which would be ammonia gas or urea] – going with the ammonia route tends to make the permeating requirements, the transportation and the handling of that re-agent much more difficult than it does urea. So urea is definitely the way to go in probably the majority of applications we’re talking [about] here.”

Loran also demonstrated the key components that are needed in the SCR system. “We need the ability to mix the urea [or] the ammonia with the exhaust”, he said. “Once I get a good mixture, then I go to a catalyst bed [which is what] creates that chemical reaction for us to break that NOx into nothing more than nitrogen and water. That’s essentially what we’re trying to get to.”

Needless to say, employing SCR technology with urea as a re-agent can efficiently lower exhaust emissions – so it’s certainly something for our Ontario greenhouse growers to consider.

“The technology’s well-proven. It’s nothing that we’re bringing that’s new.”

Well said, Loran.


We truly appreciated having Loran Novacek come from Colorado to present at Powering Greenhouses 2018. We can’t help but believe that Loran has inspired many of our guests to adopt SCR technology to reduce exhaust emissions in their greenhouse operations.
