North Haven, CT (March 10, 2025) – Precision Combustion, Inc. (PCI) announced today that it has been awarded an Army Hybrid Electric Powertrain, Power and Propulsion Systems (HEPPS) Phase I award to develop a fuel-flexible, solid-state hybrid electric power and propulsion system. The program advances PCI’s multifunctional electrochemical cells that convert the energy in liquid fuels to electricity, using a process-intensified design combining mechanical, thermochemical, electrochemical, and electrical functions. The architecture is designed for fast startups, lightweight and compact form factor, scalability, high efficiency, and fuel-flexibility, supporting low-signature power generation from logistic fuels, propane, kerosene, and sustainable future fuels.
Phase I work will experimentally validate component performance and scalability. Building on PCI’s experience with advanced SOFC-battery hybrid prototypes and assuming Phase I success, Phase II will be proposed to demonstrate a HEPPS configuration in a target application as a common-core power system that can be tailored to multiple use cases.
“Our solid-state hybrid approach is built for fast startup, compact size, low weight, low signature, and fuel-flexible operations,” said Kevin Burns, President of PCI. “By combining robust electrochemical cell materials with a process-intensified, scalable architecture, we aim to deliver efficient power and propulsion with lower logistics burden and strong path-to-deployment across multiple Army vehicle platforms.”
Commercial potential includes scalability from kW to MW with MIL-SPEC compliant power output, operation on current logistic fuels and future sustainable fuels, and application pathways spanning electrified military vehicles, soldier/squad power, electrified commercial aviation, space power generation, and automotive platforms. PCI plans to advance TRL through prototypes and demonstrations with partners to support transition to fielded systems.
