- Green ammonia has applications in hydrogen storage and transportation: Correct. It serves as an efficient hydrogen carrier, facilitating easier storage and transport of hydrogen.
- It is a key component in producing nitrogen fertilizers: Correct. Green ammonia is essential for synthesizing nitrogen fertilizers, promoting sustainable agriculture.
Thus, all four statements are correct.
4. With reference to renewable energy initiatives, consider the following statements:
- Green Ammonia is used as a carbon-free fuel and energy carrier.
- Pumped Storage Hydropower is a method of storing energy by using two water reservoirs at different elevations.
- Green Hydrogen is produced using renewable energy sources to split water into hydrogen and oxygen.
How many of the above statements are correct?
[A] Only one
[B] Only two
[C] All three
[D] None
Show Answer
Correct Answer: C [All three]
Notes:- Green Ammonia: It can be used as a zero-emission fuel and is considered a potential replacement for fossil fuels in shipping.
- Pumped Storage Hydropower: It accounts for around 95% of all utility-scale energy storage in the world.
- Green Hydrogen: It is gaining traction as a clean fuel for industries and heavy transport, helping to reduce carbon emissions.
Thus, all three statements are correct.
5. India recently signed a ‘Green Ammonia Export Agreement’ with which country?
[A] Russia
[B] France
[C] Japan
[D] Australia
Show Answer
Correct Answer: C [Japan]
Notes:
India and Japan signed their first project offtake agreement for exporting green ammonia from India to Japan. The agreement was signed in the presence of Minister of New & Renewable Energy Pralhad Joshi. This marks a key step in India’s goal to become a global leader in green hydrogen and ammonia production. The Heads of Terms (HoT) agreement involves Sembcorp Industries, Sojitz Corporation, Kyushu Electric Power, and NYK Line. It highlights India’s growing role in the global green energy sector and represents the first such collaboration between India and Japan.
6. Recently, which state of India is involved in the Memorandum of Understanding (MoU) with INOX Air Products for the Green Ammonia Plant?
[A] Maharashtra
[B] Gujarat
[C] Rajasthan
[D] kerala
Show Answer
Correct Answer: A [Maharashtra]
Notes:
INOX Air Products, an industrial and medical gases manufacturer, has entered into a memorandum of understanding with the government of Maharashtra for the establishment of a green ammonia plant. The planned investment for the project is $3 billion, and the plant is expected to be commissioned within the next 3 to 5 years. The primary objective of the facility is to produce 500,000 metric tons per annum (MTPA) of liquid ammonia. INOX Air Products, a privately-held company, currently operates in about 45 locations across India.
7. Which institution has launched the liquid nano Di-Ammonia Phosphate (DAP) in India?
[A] NITI Aayog
[B] NABARD
[C] IFFCO
[D] FCI
Show Answer
Correct Answer: C [IFFCO]
Notes:
IFFCO’s liquid nano Di-Ammonia Phosphate (DAP) was launched recently by Union Cooperation Minister Amit Shah.
500 ml of nano liquid DAP (Di-ammonium phosphate) is equivalent to one bag (50kg) of conventional granular DAP. The commercial sale was launched at Rs 600 per 500 ml bottle while the bag is currently being sold at Rs 1,350. It is expected to increase foodgrain production and curb exports.
8. Which of the following is/are the sources of Ammonia emission?- Agriculture

Show Answer
Correct Answer: D [1, 2, 3 & 4]
Notes:
The Indo-Gangetic plains, West Africa, China, the USA, and Europe are major ammonia emission hotspots, primarily due to agricultural activities and biomass burning. The Lake Victoria basin, spanning Tanzania, Kenya, and Uganda, is also a significant hotspot. West Africa’s emissions are lower than those of China, the USA, and Europe.

10. One property of ammonia is:
[A] It is insoluble in water
[B] It is a odourless gas
[C] It is a yellowish gas
[D] Its aqueous solution turns red litmus blue
Show Answer
Correct Answer: D [Its aqueous solution turns red litmus blue]
Notes:The main use of litmus is to test whether a solution is acidic or basic. For instance, ammonia gas, which is alkaline, colours the red litmus paper blue because once dissolved in water, it produces ammonium hydroxide.
