Hydrogen electric propulsion technology could be scaled up more quickly than originally thought, enabling a new generation of sustainable aircraft.

The demand for zero emission solutions to air travel has placed aviation on the cusp of its biggest transformation in decades. Hydrogen is expected to be at the heart of this new era, with both hydrogen combustion and hydrogen electric propulsion technologies critical to unlocking zero carbon dioxide emissions. However, a significant challenge for both types of hydrogen propulsion is scalability – engineering systems with the performance, weight, and hydrogen storage capacity to power larger, longer range aircraft.
