Rolls-Royce and easyJet have successfully completed ground tests of a Pearl 15 jet engine running on 100% hydrogen. The trials, conducted at NASA's Stennis Space Center, simulated a full flight profile from takeoff to landing to prove that gas turbines can be adapted for hydrogen fuel. While the test is a technical win, significant hurdles remain for commercial use. These include the need for cryogenic storage, redesigned aircraft architectures, and a complete overhaul of airport refueling infrastructure to handle hydrogen's low volumetric density.

Engine tests are fine, but the real bottleneck is the fuel. Where is the green hydrogen coming from for this scale? We need massive electrolyzer capacity and dedicated pipelines before this moves past the experimental phase.

Exactly. The tech works in a lab, but the policy side is lagging. Without clear certification standards for hydrogen airframes and massive subsidies for airport infrastructure, these engines will just sit in test cells.

Rolls-Royce and easyJet just proved a Pearl 15 engine can run on 100% hydrogen through a full flight cycle. It is a good technical step, but the article admits storage and airport infrastructure are still huge problems.
