Technology pipeline and needs

Evolutionary process need to develop and maturetechnologies in progressive steps

Many technologies are common in more electric, energyoptimized and zero emission aircraft maturation path

Power and energy densities as well as reliability of fuelcells and batteries are the biggest bottlenecks
