The Phase II contract comes on the heels of the finalised initial phase, which encompassed the conceptualisation and design planning for a naval-compliant multi-megawatt power generation system.

With this new contract, Hyliion will focus on critical technologies for the multi-Karno Core architecture.

This includes building integrated software and power electronics, refining motion control, and upgrading communications systems crucial for the operation of scaled systems.

The 18-month Phase II project is set to begin immediately, with expectations to enhance the scalability and operational control of the Karno Modules.

Hyliion founder and CEO Thomas Healy said: “Advancing the scalability and operational control of the Karno Modules is critical to meeting the Navy’s future energy needs.

“This award allows us to lay the groundwork for a highly resilient and efficient power solution that can adapt to mission requirements across both stationary and mobile defence operations.”

Key objectives during this phase involve developing software for managing multiple Karno Cores and ensuring they provide stable power in demanding situations.

The contract will also include improve the integrated drive electronics to meet specific size, weight, power, and cost (SWaP-C) criteria while adhering to naval operational standards.

Hyliion’s Karno power module relies on heat rather than combustion and supports operation on more than 20 fuel types.

It offers high-efficiency electricity generation with reduced maintenance needs and low acoustic and thermal emissions.

Following the successful initial concept design and architectural planning completed in Phase I,

Development efforts for the second phase will also be in line with Hyliion’s commercial 2MW product roadmap.

Recently, autonomous ground vehicles and robotic systems developer Stratom secured a US Navy SBIR phase I contract to develop a fully autonomous refuelling system for uncrewed naval vessels.
