What Commercial Aircraft Will Look Like In 2050
The aircraft industry is expecting a seven-fold increase in air traffic by 2050, and a four-fold increase in greenhouse gas emissions unless fundamental changes are made. But just how “fundamental” will those changes need to be and what will be their effect on the aircraft we use?
The crucial next step towards ensuring the aircraft industry becomes greener is the full electrification of commercial aircraft. That’s zero CO2 and NOx emissions, with energy sourced from power stations that are themselves sustainably fuelled. The main technological barrier that must be overcome is the energy density of batteries, a measure of how much power can be generated from a battery of a certain weight.
