In this article, the progress of Airborne Wind Energy (AWEs) systems, technology trends and barriers were studied. The concept of AWE technology, the different configurations of the system, the prototypes developed in the world was discussed, giving focus to the research developed in Brazil. The scientific and industrial community in the last decade has been working to allow AWE technology to reach the market in the coming years. AWE systems use wired aerial devices, which are lighter, less bulky and cheaper and allow access to wind energy available at higher altitudes (600m), inaccessible to current tower-based technology. AWE technology is in the research and development (R&D) and testing phase, but it still needs to mature and, therefore, there are many challenges to overcome to reach the market.
