How a new method to produce green hydrogen could help Indian industry

Green hydrogen, made using renewable energy, has the potential to decarbonise major greenhouse gas emitting sectors, such as steel.

A novel, green method of producing hydrogen could reduce global warming-causing greenhouse gas emissions and help countries achieve their climate goals.

'Green' hydrogen is produced by using renewable energy to split water into hydrogen and oxygen. In contrast, the conventional process of making hydrogen uses fossil fuels.

Hydrogen is a key input in fertilizers and refineries, so green hydrogen would help these industries cut aggregate emissions. It could also be used in steel manufacturing to reduce emissions by replacing the use of coal as the energy source and as a reducing agent.

"Till now, we have been focusing on renewable
