What H3 Dynamics does

H3 Dynamics develops high-performance hydrogen-electric propulsion systems for the aerospace and defense sector. Its core technology is based on Proton Exchange Membrane (PEM) fuel cells spanning 300W drone modules up to 4MW-class aviation systems, complemented by hydrogen storage (pressurized Type 3/Type 4 tanks and liquid hydrogen), pressure regulation, electric compression, and mobile electrolysers for on-site refueling. The company sells through two principal product lines: the AEROCELL family of air-cooled PEM fuel cells for unmanned aerial systems (A300 through A4000, 350W to 4400W) and aviation-grade liquid-cooled fuel cell stacks and systems for CS23 light aircraft, CS25 commercial aviation, eVTOLs, and large cargo UAVs (50kW to 400kW single-module configurations), with integrated powertrain solutions up to 2MW.

H3 Dynamics monetizes through three revenue streams: hardware sales of fuel cells and hydrogen storage systems, engineering and integration services covering design, qualification, certification, and manufacturing support, and long-term MRO contracts delivered through a global partner network. All sales flow through direct enterprise engagement with aircraft OEMs, retrofitters, defense contractors, and drone manufacturers — no public pricing exists, with multi-year contracts negotiated per program. Customers include Airbus UpNext (zero-emission APU replacement), Qdot (hybrid VTOL UAV), the EU-funded HyPoTraDe consortium, and the US Department of War (HyTEC program), alongside the Hycco joint venture targeting European aerospace and defense sovereignty.

The company operates a three-continent footprint: Singapore (registered HQ, H3 Dynamics Holdings Pte. Ltd.), Toulouse, France (EMEA HQ and aerospace engineering/R&D center), Pflugerville/Austin, Texas (Americas HQ, H3 Dynamics LLC), and Paris (H3 Dynamics SARL). Founded in 2006, it has accumulated roughly two decades of hydrogen-electric aviation R&D and closed a $26 million Series B led by Mirai Creation Fund in October 2021.
