Precision Combustion, Inc.

Precision Combustion, Inc., based in North Haven, Connecticut, develops catalytic energy systems, fuel cell technologies, and environmental remediation equipment for federal defense, space, and energy agencies, operating primarily as a small-business prime contractor (99% of awards) under total small business set-asides on SBIR and STTR programs. The company is registered for work across 36 distinct federal customer agencies and has accumulated $98.3 million in combined potential value across 239 prime and sub awards since 1989, with obligated dollars reaching $153.2 million.

Precision Combustion's capability portfolio centers on advanced combustion, catalytic systems, and solid oxide fuel cell (SOFC) development for aerospace, defense, and energy applications. Representative prime work includes a $2 million Army definitive contract for JP-8 fueled electrified combat vehicles (awarded March 2026, completing September 2027), a $4.78 million NASA Phase III SBIR for solid oxide fuel cell system development and evaluation for Mars applications (August 2025 award), a $1.9 million Army Phase II SBIR for direct hydrogen production from sunlight and water (September 2025), and a $1.74 million Office of Naval Research Phase III SBIR for battery thermal runaway mitigation systems (March 2025). Work on environmental life support includes a $227 thousand Sabatier reactor with balance-of-plant components (September 2025) and a $209 thousand Army contract for regenerable absorption-based continuous CO2 removal systems from closed-circuit rebreathers (September 2025). The company also holds a $1.6 million ARPA-E Phase III cooperative agreement for modular catalytic element systems to destroy ventilation air methane emissions in coal mining (awarded May 2026, completing December 2027).

Customer concentration clusters heavily in defense and space research funding. The top five funding organizations by award count account for 45% of recent awards: NASA Shared Services Center leads with 31 awards ($16.1 million), followed by Army RDECOM (25 awards, $14.3 million), Office of Naval Research (16 awards, $18.7 million), NASA direct (16 awards, $670 thousand), and Department of Energy (20 awards, dollars not separately itemized). By potential value, the ranking shifts—ONR anchors dollar concentration at $18.7 million across 16 awards, Army TACOM Life Cycle Management commands $17.8 million across 7 awards, NASA Shared Services carries $16.1 million, and RDECOM holds $14.3 million—reflecting a mature Phase III SBIR/STTR footprint where fewer but larger awards drive the dollars. The source data does not identify parent vehicle IDVs or GWACs; the vendor's work routes predominantly through agency-specific SBIR/STTR solicitations rather than standing multi-award contracts.

Activity has grown from 6 awards in 2023 to 13 in both 2024 and 2025, with recent deceleration (3 awards in 2026 to date) reflecting early-year timing. Ten awards with combined potential value of $15 million face ultimate completion inside the next twenty-four months, creating near-term recompete exposure. In its minimal subcontract role, Precision Combustion performs hydrogen recovery reactor development work for Honeywell International on flight-like advanced material reactor units, and sub-awards under Marquette University for CPOx multi-fuel reformer development and delivery. Federal grant work spans ARPA-E cooperative agreements on ventilation air methane destruction and solid oxide fuel cell systems for flight, Department of Energy Office of Science project grants on carbon capture, hydrogen generation, and metallic membrane technologies, and a NASA Innovative Advanced Concepts grant ($174 thousand, April 2025) for early-stage aerospace concepts. The vendor's NAICS concentration sits in Research and Development in the Physical, Engineering, and Life Sciences (118 awards combined across two closely related codes), with top PSC categories reflecting space R&D services and defense systems electronics research, anchoring a pure-play federal R&D footprint.
