Explanation:

NTPC Limited announced that India’s first Green Hydrogen Microgrid Projects will be set up at Simhadri near Visakhapatnam in Andhra Pradesh.

• The projects will be a precursor to large-scale hydrogen energy storage projects and would be useful for studying and deploying multiple microgrids in various off-grid and strategic locations of the country.
• The hydrogen produced during sunshine hours will be stored at high pressure and electrified using a 50 Kilo Watt Solid Oxide Fuel Cell.
• The system will work in standalone mode from 5 PM in the evening to 7 AM in the morning.
• This unique project for India, will open doors for decarbonising the far-off regions of the country like Ladakh and Jammu and Kashmir.

Hence option 1st is correct.
