Target True Zero- Infrastructure for Alternative Propulsion Flight⁠↗

Battery-electric- and hydrogen-powered aircraft could make up between 21 and 38 percent of all aircraft by 2050, representing 15 to 34 percent of the sector’s overall energy needs.

Alternative propulsion could require between 600 and 1,700 terrawatt-hours of clean energy by 2050, globally, which is equivalent to the energy generated by around ten to 25 of the world’s largest wind farms or a solar farm the size of Belgium. About 89 to 96 percent of the energy would be used for hydrogen-powered aircraft, while only 4 to 11 percent would be used to power smaller battery-electric-powered aircraft, such as turboprops, regional jets, and smaller narrow-body aircraft (Exhibit 1).
