In honor of Paddy Padmanathan, the WCSA2023 Awards presented the Visionary Technology Disruptor (Paddy Padmanathan Award) to the startup with the most impactful, visionary, and disruptive technology innovation.


Powered by ACWA Power with strategic partnerships with Dii Desert Energy, CEA-INES (The French Solar Energy Institute) and the CleanTech Business Club, the WCSA2023 Awards judging panel includes industry experts and leading CleanTech entrepreneurs.
