StellarJet, a pioneer in hydrogen-powered aviation, is proud to announce the unveiling of two groundbreaking innovations that bring the hydrogen aviation revolution closer to reality: a revolutionary Solid-State Hydrogen Storage Unit and a next-generation Electric Ducted Fan (EDF).
These two core technologies mark major milestones in the development of the hydrogen-powered StellarJet aircraft – an ultra-efficient, zero-emission platform designed to redefine the standards of clean flight.
The first innovation – StellarJet’s solid-state hydrogen fuel tank — achieves a system-level hydrogen content of 23% wt, offering 6.6 kWh/kg energy density and a safe operating pressure from 20 to 350 bar. Capable of functioning between -60°C and +80°C, the system enables fast refueling (under 30 minutes) and provides a safe, lightweight, and modular alternative to traditional liquid hydrogen tanks.

“This storage solution represents a turning point in aviation,” said Alexey Popov, CEO of Stellar Aircraft. “Until now, the limited efficiency and complexity of hydrogen storage systems held back the potential of hydrogen-powered flight. By leveraging our long-standing collaboration with experts in rocket science, our team has delivered a safe, scalable, and high-performance solution.”
This breakthrough technology surpasses liquid hydrogen in all key performance metrics — it is compact, stores more usable energy per unit weight, significantly more affordable, uses low-cost, widely available materials, and is far easier to certify under aerospace safety standards. Originally developed for space applications, this innovation brings the power of rocket science into everyday aviation.
Unlike legacy liquid hydrogen systems that pose boil-off and explosion risks, StellarJet’s solid-state hydrogen storage uses advanced metal hydride technology, enabling fully customizable tank shapes with superior safety. The system is optimized for a wide range of applications, including industrial, aerospace, satellite, and even submarine use.
