When I last looked into this, I googled electric motors in the +30MW range and found that some gas pipelines use electric turbines of that power. These are massive, stationary engines which made me wonder if the weight of the motors might be an equally serious problem as the weight of the energy storage. Carbon neutral jet fuel really seems to be the simpler alternative.
