The next big step towards ensuring a greener aircraft industry is the full electrification of commercial aircraft. That means zero CO2 and NOx emissions, with energy sourced from power stations that are sustainably fueled. In this case, the main technological barrier is to overcome the energy density of batteries, a measure of how much power can be generated from a battery of a certain weight. Read More
