With reference to green hydrogen, consider the following statements : 1. It can be used directly as a fuel for internal combustion. 2. It can be blended with natural gas and used as fuel for heat or power generation. 3. It can be used in the hydrogen fuel cell to run vehicles. How many of the above statements are correct?

Green hydrogen is produced from renewable energy sources through electrolysis, utilizing electricity from sources like solar, wind, and hydroelectric power.

Green hydrogen has various applications:

• Industry: Used in oil refining, ammonia production, methanol production, and steel production.
• Buildings: Can be blended into existing natural gas networks, especially in multifamily and commercial buildings.
• Power generation: Used for storing renewable energy and can be used in gas turbines to enhance power system flexibility.
• Vehicles: Powers Green Hydrogen Fuel Cell Electric Vehicles (FCEVs), which are zero-emission solutions, emitting only water.

Statement 3 is correct: Green Hydrogen Fuel Cell Electric Vehicles (FCEV) are powered by Hydrogen and produce zero tailpipe emissions other than water.

Statement 1 is correct: Hydrogen can be used as fuel for internal combustion engines because of its wide flammability range, allowing it to run on lean mixtures.

Statement 2 is correct: NTPC Ltd commissioned India's first green hydrogen blending project, blending green hydrogen into the piped natural gas (PNG) network of NTPC Kawas township, Surat.

All three statements are correct.
