There are various aspects of Airborne #WindEnergy Systems (#AWES), which are an emerging #renewableenergy technology that harnesses wind power at higher altitudes than traditional wind turbines. The key points are:
1. AWES use tethered flying devices like kites, wings, or drones to convert wind energy into electricity. There are two main types: Ground-Gen systems that generate electricity on the ground using the tether's mechanical motion, and Fly-Gen systems that produce electricity on the flying device and send it down the tether.
2. Compared to traditional wind turbines, AWES can access stronger and more consistent winds at higher altitudes, have lower material costs, are easier to transport and install, and have reduced visual and environmental impact. However, the technology is still immature with challenges related to reliability, durability, tether drag, intermittency, and regulatory issues.
3. Several companies and research institutions worldwide are developing AWES prototypes, including Makani Power, Ampyx Power, SkySails Group Power, Kitemill, and Altaeros Energies. SkySails launched the first commercial AWES in Mauritius in 2021.
4. #Crosswindflight, where the flying device moves in a figure-eight pattern perpendicular to the wind direction, is key to generating high power output. Basic models show that AWES power output depends on factors like wing area, aerodynamic efficiency, and wind speed.
5. The U.S. Department of Energy (DOE) sees significant potential for AWES and proposes a 10-year research and development plan to advance the technology. With further progress, AWES could play an important role in expanding wind power, especially in remote locations or offshore.
