Hyliion power modules operate as single power plant

Hyliion Holdings Corp., a developer of modular power generation technology, said it has successfully demonstrated Karno Power Modules operating together as a single coordinated generation system. During the test, two 200-kW units automatically shared changing electrical loads while maintaining stable power delivery.

Hyliion’s Karno Management System is designed to coordinate large installations of Karno Power Modules on a common network. Its distributed control architecture automatically assigns one module to coordinate the system and can transfer that responsibility to another module if the active controller becomes unavailable, improving resilience and reducing single points of failure in the system.

According to the company, the demonstration validated the Karno Management System’s ability to coordinate multiple power modules and dynamically adjust the contribution of each unit as power demand changes. In addition, it said the test supports Hyliion’s development of a standardized 800-kW building block and larger 2.4- and 3.2-MW power plant configurations with multiple 200-kW Karno systems operating in parallel.

“This demonstration validates one of the most important elements of our commercialization strategy,” said Thomas Healy, founder and CEO of Hyliion. “Karno Power Modules can now operate together as one larger power plant. It shows that customers can combine Karno Power Modules to meet the needs of an individual site while using the same standardized technology as we expand to multi-megawatt systems.”

In separate news, Hyliion announced it has been awarded a $41.7 million contract from the Office of Naval Research (ONR) to design, develop and deliver multi-megawatt Karno Power Modules for validation in land and maritime applications at NAVSEA, Philadelphia. This contract represents Hyliion’s largest military contract to date and marks a significant milestone in scaling the Karno platform toward multi-megawatt power solutions for both defense and commercial applications, the company stated.

Under the contract, Hyliion will develop and deliver two Karno Power Modules rated at 2+ MW and 3+ MW scale, expanding the platform to support a broader range of U.S. Navy vessels and applications. These systems build on the company’s modular 800-kW architecture to meet the higher power requirements of naval and land-based missions.

“This contract accelerates the development of our multi-megawatt Karno systems and expands the range of naval platforms the technology can support,” said Healy. “The Office of Naval Research has been a tremendous partner in advancing the Karno technology, and their continued investment reflects the confidence they have built in both our team and the platform.”

The multi-megawatt oower modules are expected to expand the capabilities that have driven Navy interest in the technology: fuel flexibility, high electrical efficiency and a low-maintenance design optimized for demanding operating environments. These attributes can reduce logistical burden, extend mission endurance and deliver resilient power for maritime and expeditionary operations, said Hyliion, while maintaining low acoustic and thermal signatures.
