easyJet and Rolls-Royce have successfully completed ground tests of a modified Pearl 15 engine running on 100% hydrogen. The tests, conducted at NASA's Stennis Space Center, proved the engine could handle a full flight cycle, including take-off and cruise, using gaseous hydrogen instead of traditional jet fuel. This milestone supports the goal of zero-emission narrowbody aircraft. While the engine technology is now proven at scale, the industry still faces significant hurdles regarding hydrogen production, airport infrastructure, and onboard storage before commercial deployment is possible.

Good to see a full flight cycle test rather than just a component rig. It moves the needle from theory to actual hardware, though we are still a long way from seeing these at a gate.

The engine is one thing, but the fuel supply is the real bottleneck. Where is the green hydrogen coming from? If they need massive volumes at every major hub, we are talking about a colossal amount of new electrolyzer capacity and grid upgrades that aren't in the current plan.

Exactly. The technical win is great, but without a standardized carbon accounting framework for hydrogen and clear subsidies for airport infrastructure, the economics won't work. The policy side is lagging far behind the engineering.

The article mentions the Pearl 15 is scalable for narrowbody planes. That is the critical part since those make up the bulk of short haul flights. Still, I want to see the data on non-CO2 emissions like NOx.
