Aviation contributes to about 12% of the greenhouse gas emissions in the transportation sector (i.e. road transport, rail, aviation, and shipping). The road to sustainable propulsion and power systems in commercial aviation goes through advanced gas turbine engines either as fully integrated propulsion‐air‐frame system or as hybrid electric propulsion system. Promising technologies in the propulsion system architecture are under active R&D effort at the industry, NASA, European Union's Advisory Council for Aeronautics Research in Europe, and the participating universities. The promising propulsion technologies include advanced core ultra‐high bypass‐turbofan engine, multi‐combustor, multifuel propulsion systems (using kerosene and cryogenic fuel), wave rotor topping cycle, intercooled and recuperated turbofan engines, pulse detonation engine, i.e. tapping into the unsteadiness as a means of harvesting energy. The strategy toward electric aircraft took us through hybrid‐electric architecture. The chapter discusses electric propulsion through batteries and fuel cells.
