Detailed explanation-1: -Indian scientists develop reactor for cost-effective production of hydrogen using sunlight and water.

Detailed explanation-2: -The carbon monoxide is reacted with water to produce additional hydrogen. This method is the cheapest, most efficient, and most common. Natural gas reforming using steam accounts for the majority of hydrogen produced in the United States annually.

Detailed explanation-3: -China. China consumes and produces more hydrogen than any other country – its current annual usage is more than 24 million tonnes.

Detailed explanation-4: -The two most common methods for producing hydrogen are steam-methane reforming and electrolysis (splitting water with electricity. Researchers are exploring other hydrogen production methods or pathways.

Detailed explanation-5: -Green hydrogen costs in India could potentially fall by half to as low as ₹160-170 per kg by 2030, bringing parity with grey hydrogen and other fossil fuels, says a KPMG study. Current green hydrogen production costs range anywhere between ₹320 and ₹330 per kilogram in India.
