Another EV aircraft bites the dust

After three years of research and development work, Tecnam said that currently available batteries would not be viable for operators due mainly to the need to frequently replace them. “The proliferation of aircraft with 'new' batteries would lead to unrealistic mission profiles that would quickly degrade after a few weeks of operation, making the all-electric passenger aircraft a mere 'green transition flagship’ rather than a real player in the decarbonization of aviation,” Tecnam said. “Taking into account the most optimistic projections of slow charge cycles and the possible limitation of the maximum charge level per cycle, the real storage capacity would fall below 170 Wh/kg and only a few hundred flights would drive operators to replace the entire storage unit, with a dramatic increase in direct operating costs due to the reserves for battery replacement prices.”
