Sharing a glimpse into what he plans next - diversifying his multi-billion-dollar business into renewable energy - Adar Poonawalla said, "We've bought a Swiss company with technology to make fuel cells and electrolysers. If you are talking about green energy, you need the technology to convert solar and wind into hydrogen, and transport it. So, I am waiting on India to expand its infrastructure and have policies which would then make sense where you can invest in solar and wind."
