Hyliion Holdings Corp

Previous wording

Hyliion is committed to creating innovative solutions that enable clean, flexible and modular electricity production while contributing positively to the environment in the energy economy. The KARNO generator is a fuel-agnostic power generation solution, enabled by additive manufacturing, that leverages a linear heat engine to generate electricity with significant improvements in efficiency, emissions and cost compared to conventional generators. The Company’s primary focus is to provide distributed power generators that operate on various fuel sources to adapt to an ever-changing energy economy. Hyliion is addressing the commercial space first with a locally deployable generator that can offer prime power, backup power, peak demand reduction, renewables matching and power generation from waste fuels such as landfill and flare gas. In the future, the Company plans to scale up its generator solution to address larger utility-scale power needs and to develop variants for household use and mobile applications such as vehicles and marine vessels. Additionally, the generator technology is well-suited to provide combined heat and power (“CHP”) in various stationary applications.

•Vehicle Charging: The rapid growth of consumer electric vehicles is increasingly straining grid capacity and reliability, both domestically and internationally. The introduction of commercial EVs, such as buses, delivery vans and large trucks is expected to intensify this challenge in the future given their substantial power requirements during charging. Many commercial operators cite the lack of electrical capacity access as the primary obstacle to expanding their electric vehicle fleets. Here, we believe the KARNO generator offers a unique solution for vehicle charging. Its flexibility in fuel sources, including the ability to use hydrogen, along with its superior environmental performance and low emissions and noise levels offer advantages over internal combustion generators. A KARNO generator can also modulate power without efficiency loss by activating or deactivating individual generators and by regulating the heat input to each generator. Finally, KARNO’s high power density allows it to be deployed as a localized power source for vehicle charging without displacing a large amount of parking space.

•Waste Gas Power Generation: Natural gas sourced from waste sites like landfills, water treatment plants and dairy farms is a growing market as producers seek to capture sources of methane emissions that would otherwise be released into the atmosphere or flared. Also known as renewable natural gas (“RNG”), most sources are typically treated to remove impurities such as carbon dioxide, hydrogen sulfide and moisture before the gas can be utilized or injected into natural gas pipelines. We believe the KARNO generator will compete effectively as a power generator using waste gas sources. Its modularity, coupled with its capability to oxidize a variety of fuel sources and mixtures with no or limited prior gas processing, positions it as an efficient and adaptable power generator for waste gas sources.

•Peak Shaving:“Peaking charges” also referred to as “demand charges” are fees imposed by utilities on customers based on their highest recorded electricity usage during a billing cycle, often measured over a short interval, such as 15 minutes. These charges serve to recuperate the expenses associated with maintaining grid capacity during periods of peak demand. For customers with substantial peak demand, such as large industrial facilities and data centers, peaking charges can significantly inflate their electric bills. Additionally, time-based electricity rates are now common to reduce demand on the grid during peak times. Peak rates can be two to three times higher than base rates, increasing electricity charges even further for consumers. In this context, distributed generation sources like the KARNO generator can play a pivotal role in mitigating the financial impact of peaking charges and rates by supplementing grid power during peak consumption periods.

•Backup Power: The market for local backup power generators is well established but also poised for growth due to reduced reliability of the power grid, a greater share of intermittent renewable sources of electricity, the frequency and severity of extreme weather events and the need for continuous power supply in critical applications. Generator emissions are a growing concern in the backup power market due to increased focus on the health impacts of harmful compounds such as nitrogen oxides (“NOx”), carbon monoxide and volatile organic compounds (“VOCs”). To address these concerns, emissions control technologies are often incorporated for conventional generators and alternative sources of fuel like natural gas are replacing diesel, which is also a source of particulate matter (“PM”) emissions if exhaust gases are untreated. The backup power market is another opportunity for the KARNO generator which is particularly attractive for its low level of emissions and low noise level while in operation. The KARNO generator is expected to reduce CO and NOx emissions by over 95% compared to diesel generators, and potentially without the need for exhaust aftertreatment. We therefore believe that KARNO presents an opportunity to provide solutions for end users that desire a lower emissions profile and in the event emissions regulations are further tightened.

We anticipate that the KARNO generator will achieve an electrical generating efficiency of nearly 50%, calculated by considering the usable output power in relation to the energy from the fuel source. High efficiency is expected to remain consistent across a wide range of output power levels, spanning from tens of kilowatts to multiple megawatts. In contrast, internal combustion diesel generators typically operate within an efficiency range of 25% to 40% over a similar power spectrum, while the U.S. electrical power grid is estimated to operate at an efficiency between 33% and 40%. Notably, best-in-class grid-level gas turbine powerplants can obtain efficiencies ranging between 45% to 55%. However, they incur transmission and distribution losses between 5% and 10% which the KARNO generator can circumvent by being strategically located near the point of power consumption.

The KARNO generator, functioning as a heat engine, derives advantages from its expected capability to operate across a diverse spectrum of over 20 available fuel sources and fuel mixtures. These include natural gas, propane, gasoline, jet fuel, and alternative fuels like bio-diesel, hydrogen and ammonia. Moreover, the generator can seamlessly transition between these fuels or fuel blends, requiring few or no physical modifications to its flameless oxidation system. This versatility enables a single generator to adapt to different use cases. For example, the generator may operate on natural gas for prime power generation when a pipeline connection is available and on waste gas near a landfill or dairy. Furthermore, as hydrogen becomes more widely available, the KARNO generator will be able to adapt to this cleaner fuel. As the energy landscape evolves, the KARNO generator’s fuel-agnostic nature positions it as a solution to electricity generation needs.
