High energy density hydrogen combined with H3 Dynamics high power density fuel cells and expert ancillary equipment creates world record flight performance for various types of UAS.
H3 Dynamics offers various ways of storing hydrogen, either in gaseous ore liquid form - in the fuselage or under the wings as a nacelles.

Hydrogen at the Tactical Edge of Contested Logistics (HyTEC)
The Problem: Fuel supply chains are vulnerable to disruption, and an energy-dense alternative fuel is necessary to sustain operational capabilities and improve energy resilience. While fossil fuels are energy-dense, the DoD’s reliance on them represents a vulnerability, especially for operations in remote or contested environments.
The Solution: The use of hydrogen (H2) as an alternate fuel source will help mitigate the challenges associated with fossil fuels and increase the DoD’s capabilities and reach. Fortunately, technologies are already widely available in the commercial markets in every stage of the H2 supply chain. The deliverable of this prototype effort is an integrated electrolysis-based towable H2 production and storage system capable of producing and dispensing 1 kg to 3 kg of 350 bar to 700 bar H2 in a 24-hour period. It is primarily powered by renewables with the option to use currently fielded tactical vehicles/generators.
