Energy density is one of the keys for the widespread use of UAS. For smaller UAS, added energy storage capacity will be critical to enable longer flights and heavier payloads. Markets will be enabled gradually as this performance increases. Larger UAS may use fuel or solar cells to generate their own energy, but the development of these technologies, with low cost, mass and high performance will be critical.
