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.

Consider the following statements: Grey Hydrogen is produced via coal ...
Hydrogen is a clean and versatile energy carrier that can be used in a variety of applications, including transportation, industry, and electricity generation. However, the method of producing hydrogen is crucial in determining its environmental impact.
Grey Hydrogen:
Grey Hydrogen is produced from fossil fuels, mainly coal or lignite gasification (black or brown), or via a process called steam methane reformation. In these processes, carbon dioxide is released into the atmosphere, contributing to greenhouse gas emissions. Grey hydrogen is the most commonly used form of hydrogen production due to its low cost.
Green Hydrogen:
Green Hydrogen is produced using the electrolysis of water with electricity generated by renewable energy sources such as solar, wind, or hydropower. This process is emission-free and can help to reduce greenhouse gas emissions. However, the cost of green hydrogen production is currently higher than grey hydrogen.
Conclusion:
Both statements are correct. Grey hydrogen is produced from fossil fuels and contributes to greenhouse gas emissions, while green hydrogen is produced using renewable energy sources and is emission-free. The development and adoption of green hydrogen production methods will be crucial in reducing greenhouse gas emissions and transitioning to a low-carbon future.
