UH Successfully Powers Megawatt-Class Fuel Cell Powertrain Using Company’s Proprietary Liquid Hydrogen Module

Fueling Carbon-Free Flight

Our mission is to put aviation on a trajectory to meet Paris Agreement emissions targets by making hydrogen-powered commercial flight a near-term reality.

Hydrogen is the only near-term, scalable, true zero-carbon fuel for aviation.


Hydrogen contains 3x more energy per weight than jet fuel, and enables vastly longer trips than battery power. It is the most energetic non-nuclear fuel and aviation is the most weight-sensitive application.


Hydrogen is a true zero-carbon fuel. It is made from water and its only emission is water.


Hydrogen will be at cost parity with jet fuel starting in 2025, with costs decreasing exponentially.


Hydrogen is significantly safer than jet fuel. It has a great safety record in hydrogen-powered vehicles.

An end-to-end solution for hydrogen-powered flight

We are building a flexible, scalable, and capital-light approach to hydrogen logistics by transporting it in modular capsules over the existing freight network from green production sites to airports around the world. At the airport, the modules are loaded directly into the aircraft using existing cargo handling equipment. No new infrastructure is needed. Starting with regional airplanes, we are also developing conversion kits to retrofit the existing fleet with a hydrogen fuel cell powertrain.
