“Honestly, CapEx is the most important cost metric when it comes to backup systems, because they're not used very often. You don't care that the fuel is more expensive. It's really about how cheap is your generator, and diesel is by far the cheapest solution out there.”

Wang: Voya achieves direct fully delivered cost parity with diesel
“With U.S. Scrap, you're already at diesel parity when it comes to fuel costs. Which is a critical thing for us. We're not commanding a green premium or any other sort of premium. Direct cost parity with diesel for fully delivered cost, including all the proces…”
Wang: Electrochemical aluminum conversion outperforms combustion efficiency without NOx emissions
“You can really design electrochemical systems that are incredibly cost-effective and capable, and ultimately able to convert that energy from its raw thermodynamic form in aluminum out to electricity with far higher efficiency than combustion, without any of t…”
Wang: Voya's generator runs indefinitely via continuous aluminum refueling
“And so with this, you can basically continuously refuel the cell as frequently as you need. So if you need to run continuously for a hundred hours or a thousand hours, you could do that with this design because it's a continuously refuelable system.”
Wang: Aluminum fuel is twice as energy-dense by volume as diesel
“In fact, is from a volume basis, about twice as energy dense as diesel on an as-converted basis. So come at the amount of electricity you're getting out per, you know, liter per gallon of fuel. And then even on a weight basis, you are a little bit better than …”
Wang: Voya achieves 100 MW per acre, quadrupling diesel density
“Per in terms of megawatts per acre, the power density, how much power you can pack in per acre, we are approximately a hundred megawatts per acre in our high density configuration, which is about four times higher than a diesel generator installation”
Wang: Voya cuts front-line fuel shipping volume by roughly 70%
“And then in terms of fuel logistics, especially for the military use cases where they're using the fuel so inefficiently, we have a substantial energy density benefit, about 20 to 30% Less mass and about 70% less volume shipped to the front lines for a typical…”
