Consider the following statements: Grey Hydrogen is produced via coal ...
Explanation:
Grey Hydrogen:
Grey Hydrogen is produced via coal or lignite gasification (black or brown), or via a process called steam methane reformation.
- Coal or lignite gasification: Grey Hydrogen can be produced by gasifying coal or lignite, which involves reacting coal or lignite with steam and oxygen at high temperatures. This process produces a mixture of gases, including hydrogen.
- Steam methane reformation: Grey Hydrogen can also be produced through a process called steam methane reformation. In this process, natural gas (which primarily consists of methane) is reacted with steam at high temperatures to produce hydrogen and carbon dioxide.
Green Hydrogen:
Green Hydrogen is produced using the electrolysis of water with electricity generated by renewable energy.
- Electrolysis of water: Green Hydrogen is produced by using electricity to split water into hydrogen and oxygen through a process called electrolysis. This involves passing an electric current through water, which causes the water molecules to break apart, releasing hydrogen gas at the cathode and oxygen gas at the anode.
- Renewable energy: The electricity used for electrolysis in the production of Green Hydrogen is generated from renewable energy sources such as solar, wind, or hydropower. This ensures that the process is carbon-free and environmentally friendly.
Correct Answer:
The correct answer is option C, which states that both statements 1 and 2 are correct. Grey Hydrogen can be produced via coal or lignite gasification or steam methane reformation, while Green Hydrogen is produced using the electrolysis of water with electricity generated by renewable energy.

Consider the following statements: Grey Hydrogen is produced via coal ...
Union Minister of Ports, Shipping and Waterways recently said that as per the National Hydrogen Mission of the country, Green Hydrogen/Ammonia bunkers and refuelling facilities will be established in all major ports by 2035.
About National Green Hydrogen Mission:
- It was approved by the Union Cabinet on 4 January 2022.
- Aim: To make India a Global Hub for the production, utilization and export of Green Hydrogen and its derivatives.
- The mission outcomes projected by 2030 are:
- Development of green hydrogen production capacity of at least 5 MMT (Million Metric Tonnes) per annum with an associated renewable energy capacity addition of about 125 GW in the country;
- Over Rs. Eight lakh crore in total investments;
- Creation of over Six lakh jobs;
- Cumulative reduction in fossil fuel imports over Rs. One lakh crore;
- Abatement of nearly 50 MMT of annual greenhouse gas emissions;
Types of Hydrogen based on Extraction Methods:
- Grey Hydrogen: It is produced via coal or lignite gasification (black or brown), or via a process called steam methane reformation (SMR) of natural gas or methane (grey). These tend to be mostly carbon-intensive processes.
- Blue Hydrogen: It is produced via natural gas or coal gasification combined with carbon capture storage (CCS) or carbon capture use (CCU) technologies to reduce carbon emissions.
- Green Hydrogen: It is produced using electrolysis of water with electricity generated by renewable energy. The carbon intensity ultimately depends on the carbon neutrality of the source of electricity (i.e., the more renewable energy there is in the electricity fuel mix, the "greener" the hydrogen produced).
Hence both statements are correct.
