The Government targets making India carbon-neutral by 2070, as stated by the Indian Prime Minister at the COP26 summit in Glasgow. For this goal, the much anticipated Green Hydrogen / Green Ammonia policy was unveiled on 17th February 2022, in line with the National Hydrogen Mission (NHM) announced by the Indian Prime Minister on 15th August 2021.
Industrially, hydrogen is colour-tagged depending upon the way it is produced. Green hydrogen is hydrogen gas that is produced by means of electrolysis of water using renewable energy. The setup which is used for this process is called an electrolyser.
Green Ammonia refers to Ammonia that is manufactured using Green Hydrogen, and Nitrogen from the air.
Carbon Footprint of Industrially-used Hydrogen and Ammonia (Grey Hydrogen & Grey Ammonia)
Hydrogen and Ammonia are used in various industrial processes. Currently, India consumes about 6.67 Million Metric Tonne (MMT) of Hydrogen annually. Practically all of it is ‘Grey Hydrogen’, or Hydrogen produced from Natural Gas. For every Mega Joule of energy produced from Grey Hydrogen, approximately 150 grams of Carbon dioxide equivalent emissions are produced (gCO2eq/MJ). This is comparable to any other fossil fuel’s carbon footprint.
In 2020, about 15.4 Million Tonnes of Ammonia were consumed in India. Moreover, in the period from 2022 to 2027, it is predicted that India’s Ammonia production capacity will grow at approximately 9.27 Million Tonnes annually. Currently, most ammonia is produced using Grey Hydrogen. The process of reacting Hydrogen with Nitrogen to form Ammonia (Haber-Bosch process) is also energy-consuming and requires power. About 2.1 to 3.6 tonnes of Carbon dioxide is generated for every tonne of Ammonia produced.
Scope for Going Green in Different Sectors
Green Hydrogen in the Oil Refining and Steel Sectors
About 54% of India’s Hydrogen is consumed by the oil refining sector. It is used for various refining processes, and for reducing the Sulphur content in diesel.
Hydrogen is a powerful reducing agent, which makes it useful in the metal refining processes as well. Green Hydrogen can be used in the steel industry instead of coking coal, which would make the process more eco-friendly. The steel thus produced is termed ‘Green Steel’. Also, 1 Kg of coking coal is used to produce 2 Kg of liquid metallic iron from iron ore, while 1 Kg of Hydrogen can be used to produce about 15 Kg of liquid metallic iron from ore. Even partial substitution of coking coal with Hydrogen in the Blast Furnace can significantly reduce Greenhouse Gas (GHG) emissions.
Green Hydrogen for Green Ammonia Production
Hydrogen is used in the production of Ammonia, which is a gas used in the fertilizer industry. Ammonia is also used to synthesize other chemicals and plastics. It is used in water treatment, and also as a refrigerant gas.
Switching to Green Ammonia will significantly lower the carbon footprint, as Green Hydrogen involved in the process is more eco-friendly to produce, and the energy supplied for the production of Ammonia shall also come from Renewable sources.
Therefore, the use of Green Hydrogen and Green Ammonia will help in reducing the carbon footprint of several industries.

International Status of Green Hydrogen / Green Ammonia
The EU has set a target of installing an electrolyser capacity of 40 GW for Green Hydrogen production by 2030. Several countries have pledged to be net-zero carbon emission nations in the coming years. China has planned to have 1 million Hydrogen Fuel cell-powered vehicles (FCEV) before the close of 2030. Japan’s Toyota has led significant research and investment in Hydrogen fuel cell technology. Australia too has a plan to invest $214 million to install 26 MW capacity worth of electrolysers.
Future Plans to promote Green Hydrogen / Green Ammonia in India
India’s Green Hydrogen Policy addresses issues on the supply side of the Green Hydrogen / Green Ammonia production process.
For the demand side, the Indian Government will introduce mandates to encourage a shift to Green Hydrogen as an industrial raw material and as a source of clean energy. This entails making it compulsory for industries to procure a certain percentage of the required hydrogen / ammonia from Green Hydrogen / Green Ammonia manufacturers. This percentage can start from 15-20% in refineries and can be later increased to 30-40%, as mentioned by the Union Power Minister, RK Singh during a conversation with The Indian Express, released on 5th October 2021.
To show his support for the adoption of Green Hydrogen in India, Mr. Nitin Gadkari, Union Minister for Road Transport and Highways drove a Green Hydrogen-powered car to the Parliament on 30th March 2022.
Challenges in Adopting Green Hydrogen / Green Ammonia
Green Hydrogen is expensive to produce. Production of 1 Kg of Green Hydrogen costs around $3.5 to $6 while production of Grey Hydrogen costs between $1 to $2 per Kg. This cost difference makes Grey Hydrogen an economical choice. Due to this cost difference, the production of Green Ammonia becomes expensive as well. Therefore, for adopting Green Hydrogen and Green Ammonia, steps to make the production process cost-effective must be identified and implemented.
It is most convenient to consume Hydrogen near the site of production, as is done at many Ammonia plants and oil refineries. Transportation of Hydrogen is challenging since it is the lightest element in the universe. If Hydrogen is to be transported, it is done either through special pipelines or in special containers. Owing to Hydrogen’s low density it must be transported through pressurised pipelines to make the process cost-effective. Liquefaction of Hydrogen is also an option but requires it to be cooled to -253°C. Once liquified, Hydrogen is transported in special cryogenic vessels. Therefore, ways of transporting Hydrogen affordably and viably need to be explored further.
Moreover, Hydrogen is highly flammable. It is prone to combusting explosively and has safety risks associated with its usage and storage.
