Rolls-Royce and easyJet complete 100% hydrogen ground test of modified Pearl 15 at full takeoff power

Rolls-Royce and easyJet have completed a major hydrogen fuel milestone, running a modified Rolls-Royce Pearl 15 aircraft engine on 100% hydrogen at full takeoff power during a ground test at NASA’s Stennis Space Center in Mississippi. The result advances research into lower-emission aviation fuel pathways.

Briefing

What Hype is tracking

  • The 100% hydrogen run at full takeoff power provides a concrete propulsion-relevant data point for hydrogen adoption, moving beyond feasibility work into higher-load engine demonstration.
  • It supports the same hydrogen propulsion trajectory seen in other OEM and certification-track efforts, including Airbus’ ZEROe hydrogen fuel-cell concept progress (source:d933de96-0067-4561-a193-4a59f2ad8113) and the regulatory pathway for hydrogen-electric engines (source:8a4e6c35-d9b6-4632-8afc-6f5c7d9faad3).
  • The test location and milestone framing matter for airlines assessing near-term operational risk, because it shows an engine can be exercised on-site under representative high-power conditions rather than limited bench characterization.
