To date, global efforts to generate clean energy from wind have focused on building towers with energy producing turbines at the top. But there is another option for getting energy from wind: airborne wind energy systems (AWES), turbines tethered to the ground by cables. These take many forms, from soft kites to ring-shaped blimps, and operate at altitudes where winds are stronger and more predictable, which may help eliminate some of the intermittency of wind energy. Because AWES can generate power without building large towers, they have the potential to be a cheaper form of wind energy and may be especially useful to help off-grid communities switch away from diesel. So why are there no large-scale deployments of AWES yet? In this talk, Markus Sommerfeld will give an overview of current developments and what we can expect in the future of airborne wind energy. He will outline the potential of AWES and the technological and regulatory challenges to large-scale deployment.
