"Pulsed Joule Heating" Technology Enables Ultra-Efficient Snow, Frost and Ice Removal from Renewable Energy Devices
Extreme weather events caused by global warming can bring unexpected snow, frost and ice on the surfaces of renewable energy devices, such as photovoltaic (PV) panels and wind turbine blades. To tackle this problem, LI Longnan from Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) and his co-workers from University of Illinois Urbana-Champaign developed a multifunctional coating material to remove snow, frost and ice from surfaces by using “Pulsed Joule Heating” method. This method involves pulsed interfacial Joule heating through thin conductive film, integrated with controlled surface wettability to achieve interfacial defrosting without bulk melting.
