Airbus
Airbus’ fully electric aircraft, ZEROe, will use hydrogen fuel cells as a power source. Scalable and hydrogen powered, these fuel cells produce only water vapor as a byproduct of the chemical reaction that creates the electricity. However, in order for the fuel cells to be a carbon neutral solution for aviation, the hydrogen used must be made from electrolysis using renewable energy. Unfortunately, demand for this renewable hydrogen, also called green hydrogen, vastly exceeds the supply.
