Billionaire businessman Gautam Adani today sought more collaboration between India and the US on healthcare, defence and cyber technologies while announcing that his group will build three giga factories for manufacturing solar modules, wind turbines and hydrogen electrolysers by 2030 as part of a $70-billion investment plan in clean energy. These giga factories will generate an additional 45 GW of renewable energy to add to Adani group’s existing 20 GW capacity, as well as three million tons of hydrogen by 2030. The announcement comes weeks after Reliance Industries Chairman Mukesh Ambani announced a fifth giga factory as part of investment in low carbon energy.

Speaking at the US-India Business Council here on Wednesday, he also sounded a note of caution about India’s dependence on global supply chains, as chips are required by everyone.
