At the Defense Manufacturing Conference, NRL researchers Cronin and Rodgers bagged the Technology Achievement Award for Lightweight Hydrogen Fuel Cells. These cells promise enhanced endurance for unmanned aerial systems, a critical need in Defense's persistent ISR and RF communication. Their innovative system offers low signature capability, supporting reduced emissions and extended operational capabilities for military UAVs.



Recognizing the crucial demand for increased power and endurance in Defense operations, NRL's researchers, Kevin Cronin and Drew Rodgers, secured the Technology Achievement Award for their groundbreaking Lightweight Hydrogen Fuel Cell innovation at the recent Defense Manufacturing Conference held in Nashville, Tenn.

Cronin, hailing from the Chemistry Division's Alternative Energy Section, expressed pride in contributing to this impactful project, emphasizing the team's dedication to pushing the boundaries of science and technology. Their project transitioned from fundamental research to a fully-fledged system, now poised for integration and adoption by domestic manufacturers.

The hydrogen fuel cells exhibit suitability for low-signature applications owing to their electrochemical energy generation, resulting in fewer moving parts and reduced operating temperatures compared to combustion engines. Moreover, these cells produce water as a byproduct, aligning with efforts to curb carbon emissions.

Rodgers, from the Tactical Electronic Warfare Division's Vehicle Research Section, highlighted the collaborative efforts to develop mechanical designs essential for the assembly and integration of fuel cell components into unmanned vehicles. This endeavor culminated in years of dedicated work, promising enhanced capabilities for the warfighter both presently and in the future.

However, commercially available hydrogen fuel cells for UAS have yet to meet the demands of military applications. The absence of a lightweight fuel cell vendor in the U.S. that produces systems within the 1-3 kilowatt range creates a manufacturing gap, limiting the deployment of RF surveillance-capable UAVs.

The OSD Manufacturing Science and Technology Program (MSTP) addressed this gap by establishing a mature fuel cell system and nurturing a domestic manufacturing base. This breakthrough technology promises wider applications beyond UAS and fills critical capability gaps for the military.

NRL's fuel cell research, backed by various defense entities like OSD MSTP, ONR, NAWCAD, and USMC E20, aims to bolster energy sources for Marines, supporting longer UAV flights and quieter generators. This aligns with the Marine Corps' goals of reduced fossil fuel consumption for increased combat effectiveness.

The collaborative efforts of NRL with various defense agencies, including NAWCAD's contribution to fuel cell maturation and integration into the Stalker UAS, highlight the significance of collective efforts in advancing military technology.

In a bid to reduce energy consumption, the Marine Corps' Expeditionary Energy Office aims to cut liquid fossil fuel dependence by 50% by 2025, prioritizing liquid fuel solely for energy-efficient mobility systems.

Dr. John N. Russell, Jr., NRL Chemistry Division Superintendent, emphasized NRL's commitment to innovative research, contributing to U.S. Naval power through multidisciplinary scientific endeavors.


The NRL's pioneering Lightweight Hydrogen Fuel Cell initiative represents a remarkable stride in bolstering Defense capabilities. This breakthrough technology, recognized at the Defense Manufacturing Conference, promises extended operational endurance for unmanned aerial systems, aligning with the military's quest for enhanced ISR and reduced emissions. The collaborative efforts and innovative strides underscore NRL's commitment to driving cutting-edge advancements in defense technology, fostering a stronger and more resilient military apparatus.
