The Centre is planning to make the use of green hydrogen mandatory in some sectors as part of the National Hydrogen Mission. The plan is to replace the use of imported ammonia in agriculture, petroleum, steel and other sectors. “We are going to have green hydrogen bids in another four-five months,” R K Singh, union minister for power and new and renewable energy said. He said discussions have already being held with the ministry of petroleum and natural gas, ministry of steel, and ministry of chemicals and fertilisers. “We import ammonia. Suppose we have a mandate, like we have the Renewable Purchase Obligation. To begin with 10 per cent of the ammonia which you are importing will be replaced by green ammonia made in India,” Singh said. He said similar mandate can be made for hydrogen consumption by refineries, steel industry etc.
