Rolls-Royce and EasyJet have completed ground tests with an early concept demonstrator for a hydrogen propulsion system that they hope will eventually be capable of powering narrowbody airliners. The partners announced on November 28 that they recently ran a modified Rolls-Royce AE 2100 A turboprop airliner engine on green hydrogen made from wind and tidal power inspired by the United Nations-backed Race to Zero campaign to achieve net zero carbon emissions by 2050.
A series of ground tests conducted during November with the concept demonstrator at the UK’s Boscombe Down defense research facility has prepared the way for full-scale ground tests using the Pearl 15 turbofan engine that Rolls-Royce developer for Bombardier’s Global 5500 and 6500 business jets. Eventually, the engine maker intends to scale up the technology to work with large turbofans needed for aircraft such as the Airbus A320 family operated by Easyjet across Europe.
