Background
This is a major infrastructure development project with significant economic, environmental, and strategic implications. It contributes to India's climate goals, energy security, and modernizes a critical transport backbone, aligning with sustainable development objectives.
Indian Railways has undertaken one of the world's largest and fastest railway electrification programs, aiming to electrify its entire broad gauge network. This initiative is crucial for enhancing operational efficiency, reducing reliance on fossil fuels, and mitigating carbon emissions in the transportation sector.
Facts & tables

In the context of proposals to the use of hydrogen-enriched CNG (H-CNG) as fuel for buses in public transport, consider the following statements :
1. The main advantage of the use of H-CNG is the elimination of carbon monoxide emissions.
2. H-CNG as fuel reduces carbon dioxide and hydrocarbon emissions.
3. Hydrogen up to one-fifth by volume can be blended with CNG as fuel for buses.
4. H-CNG makes the fuel less expensive than CNG.
Which of the statements given above is/are correct?
Statement 1 is incorrect: While H-CNG significantly reduces carbon monoxide (CO) emissions, it does not eliminate them entirely. Burning hydrogen produces only water vapor, but since H-CNG is a blend of hydrogen and CNG, some CO is still emitted though at lower levels than conventional CNG. Statement 2 is correct: H-CNG is cleaner than CNG, leading to a reduction in carbon dioxide (CO₂) and hydrocarbon (HC) emissions. The reduction depends on the specific blend ratio and engine efficiency. Statement 3 is correct: As per Indian government guidelines, up to 18% hydrogen (by volume) can be blended with CNG for use in buses and other vehicles. This blend improves combustion efficiency and reduces emissions. Statement 4 is incorrect: H-CNG is not necessarily cheaper than CNG. The cost is influenced by Hydrogen production methods, Infrastructure development and Blending technology. Therefore, option (B) statements 2 and 3 are correct.
Which of the following statements with regard to Green Hydrogen is/are correct ?
1. It is decarbonized hydrogen obtained from natural gas reforming combined with carbon capture and storage (CCS).
2. It is produced using electrolysis of water with electricity generated by renewable energy.
3. National Green Hydrogen Mission of India aims for abatement of nearly 50 MMT of annual greenhouse gas emissions by 2030.
Select the answer using the code given below :
Statement 1 is Incorrect: Hydrogen obtained from fossil fuels (primarily natural gas) through steam methane reforming, where the resulting carbon emissions are captured and stored using Carbon Capture and Storage (CCS) technologies, is known as Blue Hydrogen, not Green Hydrogen. Statement 2 is Correct: Green Hydrogen is produced by splitting water into hydrogen and oxygen via electrolysis, using electricity generated entirely from renewable energy sources (such as solar or wind). It is a completely zero-emission process. Statement 3 is Correct: The National Green Hydrogen Mission launched by the Government of India has set quantified targets for 2030. It aims to develop a green hydrogen production capacity of at least 5 MMT (Million Metric Tonnes) per annum. This will lead to the abatement of nearly 50 MMT of annual greenhouse gas emissions by 2030, alongside reducing fossil fuel imports and creating over 6 lakh jobs. Therefore, the correct option is B.
Which one of the following is the exhaust pipe emission from Fuel Cell Electric Vehicles, powered by hydrogen?
Fuel Cell Electric Vehicles (FCEVs) powered by hydrogen generate electricity by combining hydrogen (H₂) with oxygen (O₂) in a fuel cell. This process produces electricity, heat, and the only exhaust emission is water vapour (H₂O), making hydrogen fuel cells zero-emission.
