Hello, everyone. My name is Thomas Healy, I'm the founder and CEO of Hyliion. Today I'm here to talk about electricity. Hopefully many of you have experienced that you need a lot of electricity in order to power these EVs. We're going to talk about a new way of thinking, a way where we think the future is you make your own power on-site as opposed to being reliant on the grid. With that, you can actually see our power module on the slide here to my left. These are designed to be your prime power solution. Think about a facility. Right now, it has an air conditioning system outside. Well, we think the future is, in addition to having an AC system, your facility will also have a power plant sitting right outside providing all the power that you need. That unravels a lot of questions like, can you make electricity as efficient as the grid? Is it reliable? What's the cost of it? We're going to cover all of that, but we believe that with our technology breakthrough with this KARNO modular power plant, you now actually have the ability to feasibly make your own power and be more economical than buying from the grid.
Let's dive into what applications where we see making your own power make sense. The first is EV charging. This is something that over the last few years I've talked about at ACT Expo, which is plugging in 10 of these electric semi trucks into the grid consumes the same amount of electricity as the entire Super Bowl stadium during game time. When you think about going out and deploying an EV charging site, this isn't just an easy equation of asking your utility for a grid interconnect and you're going to have the power easily available. That's not the case. These trucks can consume a tremendous amount of power. Couple that with a massive increase in power demand happening across many industries right now, one of the main ones being with AI and data centers. As we just shared earlier today in our product unveil, the latest and greatest data centers being built, their amount of energy consumption is actually 100x the amount of plugging in 10 EV semi trucks, so that's equivalent to 1,000 trucks being the same as one data center.
Now that unravels a lot of questions around, who's willing to pay more for the electricity? From the numbers we've seen, the reality is data centers are going to win every day in that equation. The amount they're willing to pay for electricity and the need for powering these computers is huge. It's a situation where they will come to the table and be willing to pay more. We're already seeing that happen in the oil and gas space where there are companies who provide modular power plants into oil and gas and data centers are coming in and saying, we'll pay you double what the oil and gas providers are paying to steal those generators and bring them to power an AI data center. The last part where we think distributed grids make a lot more sense is if you look at our utility today, 60% of the transmission lines in the US are already at their end of life or past their end-of-life expectancy. Either we go build a bunch more power plants and then build a bunch of transmission lines to bring the power to the end destination, or what we think is going to happen is we move to this model of make your own power on-site.
A little bit of background on Hyliion. I founded the company back in 2015. We are headquartered in Austin, Texas. We are listed on the New York Stock Exchange American exchange, and then we also have an R&D facility up in Cincinnati. Some of you might be familiar with us from years past of being a powertrain company here at ACT Expo. Over the past two years, we actually made the strategic shift of moving out of building electric powertrains, going all-in on stationary power gen. It's through this KARNO technology, which we actually acquired out of GE Aerospace a few years back.
What applications are most relevant? EV charging, data centers, we've talked about a lot; waste gas. One of the things I'm going to cover is how the system's truly fuel-agnostic. You can actually take methane coming off of landfills, gas coming out of oil and gas wellheads, and run that right through the system without even needing to purify the fuel beforehand. The next is prime power. Think of just standard facilities moving those to make your own power. The real driver there is the low-cost nature of it, where you can actually make electricity cheaper than the grid. The last one, which we're pretty excited about, is we actually have a contract with the US Navy to power future autonomous navy vessels, which is pretty neat, and one where we're actually using liquid fuels, using diesel to power those.
This is the technology, it's called the KARNO core. It's this four-shaft system designed to produce 200 kilowatts of power, and it's structured as a linear heat generator. I'll cover a little bit more how it works, but you've got those four shafts. The benefits that come from it: I mentioned the first already, truly fuel-agnostic. Most deployments are going to run on natural gas just because that's the fuel that's most relevant and readily available. But we also have applications that are going to run on hydrogen, on diesel, on captured methane. We've identified over 20 fuels that this system can run on, with ultra-low emissions. You can see some of the numbers there, achieving single-digit parts per millions of NOx and CO levels. To put that into comparison, if you take a standard natural gas engine, a recip engine, our emissions levels are on the order of magnitude of 98% to 99% lower than what a standard recip would be, and that's with zero aftertreatment system. Efficiency is 50%. To put that into comparison, the US electric grid on average is about 36% efficient. Now you have the ability to make electricity on-site more efficient than even the utility. Then low maintenance, only one moving part, as well as low noise.
We take that four-shaft system, we package it in an enclosure with all the balance of plant, and that is what would actually be deployed at an EV charging site, each one of those boxes producing up to 200 kilowatts of power. We are also working on a two-megawatt variant of the product as well, which takes 10 of those four-shaft systems and packages them together into a box that's about the same size as a 20-foot shipping container.
Let's now talk about how does this actually work. It's based on a concept of Stirling engines. If you go back 200 years ago, there were steam engines, there were reciprocating engines, and there was this thing called a Stirling, which most engineers knew was the best way to make power. The problem was that it was almost impossible to manufacture. What we've done is we've said, what if we apply the latest and greatest in manufacturing techniques, aka 3D printing or additive manufacturing? We can actually make those really complex parts and bring forward a 200-year-old technology. The way it works is, on the outsides of the system, we bring fuel in, we react it to make heat, and heat is actually the fuel source of this power system. That's what makes it very unique is that we can get heat from anywhere. We can get it from natural gas; we can get it from hydrogen. You bring the fuel in, you react it, make heat, and then in the center area we have a trapped gas, and it's helium inside. What happens is when you heat that gas up, it wants to expand, and when it expands, it pushes the piston down one way, and then you do the opposite reaction on the other side and push it back. You have that shaft oscillating back and forth, and that's what's making electricity through a linear motor in the center.
The unlock of this technology, as I mentioned before, is 3D printing or additive manufacturing. You can stop by our booth and actually see these parts live and in person. That's an example of one on the left-hand side; that's a heat exchanger within the KARNO. The machines on the right are what actually make those parts. In our Cincinnati facility as well as Austin, Texas facility, we have a very large installed base of 3D printers that are sitting there running 24/7, making the components that go into the KARNO. The last thing I wanted to share is, how does this all stack up? If you compare it on what customers care about the most—electricity, maintenance, emissions, footprint, and upfront capital cost—on almost all of those, we are near the top or at the top in terms of performance. It's the only solution that really is able to bundle all those together into one product. What most people care about when you're actually thinking about adopting a solution like this is the TCO, that payback, which, while it does have an upfront cost that is higher, the actual efficiency of the system and the low-maintenance nature allow you to have a pretty fast payback. With that, the big story here is we need a lot more power, whether it's for EV charging, whether it's for data centers. We think the model's going to be a distributed grid as opposed to big power plants, and we see the KARNO generator as the way to make on-site power. Thank you very much, everyone.
