PRODUCT LAUNCH: HPDG-30 Hybrid Powerplant

H3X Technologies

H3X Technologies has announced the HPDG-30, a breakthrough in its hybrid powerplant roadmap, designed to deliver high power density in an ultra-compact and efficient package. This new product combines a high-performance combustion engine with H3X’s HPDM-30 generator, offering a complete hybrid-electric solution tailored for aerospace and defense applications.

Key performance highlights include:

  • 30 kW electrical output in a compact 32 kg package
  • Hybrid architecture: Combustion engine + HPDM-30 generator
  • Liquid fuel input → High-voltage DC output (180–800V)
  • Effective energy density of 580 Wh/kg with 1 hour of onboard fuel
  • Up to 840 Wh/kg with 2 hours of fuel – over 4× higher than lithium-ion batteries
  • Closed-loop cooling system – no external cooling support required
  • Target TBO (Time Between Overhaul) of 500–1000 hours
  • DFARS-compliant supply chain 🛡️

The HPDG-30 is designed to be modular, rugged, and ready for mission-critical environments, offering unmatched performance in applications where weight, endurance, and power density are paramount.

"This is the latest step in our mission to deliver the most power-dense solutions in the world,” said the H3X team. “With the HPDG-30, customers can achieve longer range, more payload capacity, and more flexible architectures for hybrid-electric platforms."

The HPDG-30 is now available for early access programs. For more information or to inquire about evaluation units, contact the H3X team.
