It helps airlines meet their sustainability goals with a new propulsion system that is fully compatible with sustainable aviation fuel (SAF) as well as hydrogen. Engine efficiency is optimized through a hybrid-electric component that enables electrification of many aircraft systems. The US-based and French firms also extended their CFM 50-50 partnership through 2050. The CFM RISE (Revolutionary Innovation for Sustainable Engines) program aims to have a new generation of CFM engines in service by the mid-2030s. GE's CEO John Slattery said that, "we are reinventing the future of flight, bringing an advanced suite of revolutionary technologies to market that will take the next generation of single-aisle aircraft to a new level of fuel efficiency and reduced emissions. We fully embrace the sustainability imperative." Rival Rolls Royce is working on an Ultra Fan engine that can operate with 100% SAF (JFI Apr.1'21).
