Hyliion Awarded Government Contract to Create a Megawatt-Scale Concept of the KARNO Generator Technology for the United States Navy

AUSTIN, Texas--(BUSINESS WIRE)-- Hyliion Holdings Corp. (NYSE: HYLN) ("Hyliion"), a developer of sustainable electricity-producing technology, is pleased to announce that it has been awarded a Small Business Innovation Research (SBIR) government contract by the United States Navy. Phase 1 of the award, N241-060, will allow Hyliion to create a preliminary design of a modular generator system that integrates the Navy's specifications with Hyliion's cutting-edge KARNO ^™ generator technology.

With this contract, Hyliion will showcase a design concept of the KARNO generator in a megawatt-scale modular system. The system will be engineered to offer a versatile and flexible approach to meet the U.S. government's Unmanned Surface Vessel (USV) cross-platform requirements, scalable to various power needs and adaptable to the available platform space. Hyliion plans to leverage its foundational 200-kilowatt (kW) KARNO genset, combining multiple units together to achieve the desired power output.

"We are honored to receive this SBIR contract from the United States Navy," said Thomas Healy, Founder and CEO of Hyliion. "This award is a testament to the KARNO generator's expected ability to offer efficient, flexible, and low-maintenance power generation. We are excited to contribute to the Navy's mission and explore higher power solutions for their USV initiative."

The SBIR program is an initiative that supports scientific excellence and technological advancements by investing federal research funds in key American priorities aimed at strengthening the national economy and defense infrastructure. The primary objective of the N241-060 program is to develop and demonstrate a megawatt (MW) scale, ultra-reliable, and efficient USV modular generator concept tailored to the Navy's requirements. This concept involves configuring smaller kW-scale building block power units in a high-density package to achieve a 4,000-hour no-touch maintenance periodicity for continuous operation in a naval environment.

This government contract underscores Hyliion's commitment to innovation and its leadership in developing sustainable energy solutions. The KARNO generator, with its exceptional form factor and ability to operate on multiple fuels, including NATO F-76, is ideally suited for the Navy's USV program. The system's hermetically sealed architecture, with only one moving part per shaft, is designed for maintenance-free operation over long running hours.

About the KARNO Generator

The KARNO generator is a linear heat generator that leverages advanced 3D metal printed components and proprietary flameless oxidation technology to produce clean electricity. Modular in design, the generator is expected to show an improvement in fuel efficiency, require significantly lower maintenance costs and have a much lower emissions profile than conventional generators. It is also capable of operating on over 20 different fuels, including hydrogen, natural gas, propane, ammonia and conventional fuels.
