It's going to be pretty important for short range aviation (electric engines are more reliable, deliver a lot of power compared to their size and weight and jet fuel is a major cost) and it could still be a major boon for long range aircraft. For example using lightweight electric engines to boost aircraft power during takeoff and climb and then cruising on jet engines specialized for efficiency at high altitude and cruising speed.
