This represents a giant leap towards a global shift towards green energy for India, as Larsen and Toubro (L&T) recently partnered with Japanese multinational corporation ITOCHU Corporation to supply 300,000 metric tons of green ammonia per year. This deal represents a crucial step in establishing India as a primary producer of green fuel exports, as well as increasing energy cooperation between India and Japan.

The company behind this landmark partnership is none other than L&T Energy GreenTech Ltd (LTEGL), a wholly-owned subsidiary of L&T that will be responsible for producing and delivering this green ammonia in large quantities from its planned manufacturing site in Kandla, Gujarat. The deal is designed as a long-term “take-or-pay” arrangement, which guarantees both parties that the project will be financially viable.

It should be noted that, in recent years, green ammonia produced by using alternative energy sources like solar and wind energy has been gradually becoming an essential element of the decarbonization process across the globe. This type of ammonia can significantly contribute to environmental protection as compared to the conventional one due to almost zero carbon emissions. Furthermore, it is being used more and more frequently by various industries, especially by those associated with power generation, shipping, and fertilizers.

The importance of the partnership between L&T and ITOCHU lies in the fact that Japan, the country that lacks indigenous energy resources, has made a lot of efforts towards developing clean energy imports in order to meet their climate goals. As a result, ITOCHU is trying to strengthen the existing supply chain of green ammonia globally, focusing primarily on the development of maritime ecosystems in Singapore.

The benefits of this collaboration for India cannot be overlooked as well. The cooperation of both companies is directly connected to India's plans regarding becoming the center of producing green hydrogen and its derivatives as outlined in the National Green Hydrogen Mission of the government.

The strategic value of the initiative is bolstered by the fact that it takes place in Kandla, Gujarat. As one of India's ports located on the west coast of the country, Kandla will have logistical benefits when shipping green ammonia internationally. It is anticipated that the installation will become an essential node in emerging green energy supply chains, particularly those running from India to East Asia.

Moreover, the present initiative is a part of a larger trend in cooperation between the two organizations. The development agreement signed back in 2025 is already evolving into a commercial enterprise as it progresses towards its implementation. This development demonstrates how much greener hydrogen and ammonia industry has grown since then.

From the economic standpoint, the agreement could lead to additional investments into developing technologies, expanding facilities, and creating jobs associated with production and shipment.

Nevertheless, there are still challenges ahead. For example, large-scale green ammonia production is highly dependent on cost-effectiveness, efficiency, and government support. Even though renewable energy prices have been falling, producing the required amounts to satisfy global energy demands would necessitate continuous political support and private capital investment.

In spite of the challenges, the deal between L&T and ITOCHU is a significant development in the worldwide shift towards sustainable energy. It emphasizes the increasing importance of global cooperation in mitigating climate change and the rise of India as a prominent player in sustainable energy development.

In conclusion, as countries transition towards achieving low-carbon energy production goals, partnerships similar to this one will become increasingly important in creating interconnections within green energy networks.

Green ammonia, or ammonia (NH₃) made with low-carbon and renewable energy sources, is quickly becoming a flexible decarbonisation option. It can be utilised as an alternate fuel for transportation and electricity production, a long-duration energy storage medium, an industrial feedstock, and a zero-carbon hydrogen carrier. This article describes what green ammonia is, how it's produced, why it's important, the difficulties it confronts, and what to watch next.

265.1) What is Green Ammonia?

One nitrogen and three hydrogen atoms make up the molecule known as ammonia (NH₃). Traditionally, the Haber-Bosch process is used to create ammonia on a large scale from hydrogen supplied from fossil fuels, which results in significant CO2 emissions. In low-carbon Haber-Bosch or developing synthesis techniques, green ammonia replaces fossil hydrogen with hydrogen generated by water electrolysis powered by renewable electricity (wind, solar, hydro). This hydrogen is then paired with nitrogen (from air separation). Lifecycle CO2 emissions can be almost zero when produced in this manner.

265.2) How Green Ammonia is produced?

1) Renewable energy sources, such as solar, wind, hydro, geothermal, or a combination of these. The chain is made "green" by this energy source.

2) Hydrogen is produced by electrolysis, which uses electrolysers (PEM, alkaline, or solid oxide) to separate water into hydrogen (H₂) and oxygen (O₂). For electrolysis to be considered green, the power used must be renewable or carbon-free.

3) Ammonia synthesis and nitrogen separation: An air separation device is used to extract nitrogen (N₂) from the air. An ammonia synthesis unit combines nitrogen and hydrogen. Innovators are creating lower-temperature, modular, or electrochemical synthesis pathways that better suit fluctuating renewable input, while the traditional approach is Haber-Bosch (high temperature and pressure with catalysts).

265.3) Why Green Ammonia matters?

1) Decarbonising industry and fertiliser: One important industrial chemical and fertiliser feedstock is ammonia. Industrial CO2 can be significantly reduced by producing it with minimal or no emissions.

2) Hydrogen carrier and export fuel: Ammonia can be delivered using current bulk chemical logistics, fractured back to hydrogen close to end-use, or used directly as fuel. It stores hydrogen densely (by volume and mass). Because of this, green ammonia is a viable means of transporting hydrogen internationally.

3) Ammonia's capacity to store energy for extended periods of time aids in the integration of significant proportions of variable renewable energy sources. In remote or island systems, it is appropriate for power generation and seasonal storage.

4) Maritime fuel and power generation: If NOₓ and other emissions are controlled, ammonia can provide zero-carbon propulsion for ships and zero-carbon power for heavy-duty applications when burned in modified engines or utilised in fuel cells.

5) Scaling renewable energy is made possible by green ammonia, which opens up gridscale storage possibilities and economic value by acting as a demand sink for large renewable energy projects in areas with plenty of solar or wind power.

265.4) Technical and Economic Challenges

1) Cost competitiveness: Due to electrolyser CAPEX, the volatility of renewable electricity prices, and the capital expenses of new synthesis units, green ammonia is now more costly than traditional (fossil) ammonia. Costs are decreasing, but electrolyser scale and inexpensive renewable electricity are essential for competitiveness.

2) Electrolyser durability and scale: In order to lower the cost of levelized hydrogen, electrolysers must increase their lifespan and efficiency.

3) Integration and intermittency: While traditional Haber-Bosch facilities are built to run continuously, integrating fluctuating electrolytic hydrogen calls for either innovative modular synthesis technologies or operational flexibility.

4) Infrastructure and logistics: Ammonia-compatible pipes, safe handling methods, storage tanks, and ship bunkering infrastructure are all necessary for widespread use.

5) Concerns about safety and the environment: Ammonia is corrosive and poisonous, and leaks endanger both humans and ecosystems. Strong safety regulations, oversight, and emergency preparation are crucial.

6) Regulation and certification: To guarantee really low-carbon supply chains and prevent "greenwashing," clear standards and lifecycle accounting (guarantees of origin, hydrogen and ammonia certification) are required.

7) Control of NOₓ emissions: Nitrogen oxides can occur when ammonia burns; methods and catalysts are needed to reduce and collect NOₓ to acceptable levels.

265.5) Business Model & Use Cases

1) Fertiliser manufacturers can reduce emissions by integrating electrolysis with current ammonia plants.

2) Exporters of renewable energy: nations with a plentiful supply of renewable energy can manufacture green ammonia for export as a commodity.

3) Shipping bunkering: For long-distance shipping, ports and shipping firms can provide ammonia as a carbon-free bunker fuel.

4) Power plants and industrial heat: When electrification is difficult, ammonia can power internal combustion engines or turbines for grid balancing or industrial heat.

5) Seasonal energy storage: Extra electricity from renewable sources can be transformed into ammonia, stored, and then either burned or converted again at a later time.

265.6) Policy, finance & incentives

Green ammonia is accelerated in large part by public policy:

1) Green ammonia is more affordable than fossil ammonia thanks to carbon pricing or credits.

2) Upfront capital obstacles are reduced by grants and subsidies for electrolysers, renewable energy, and pilot projects.

3) Standards and certification prevent double counting of renewable qualities and guarantee trade integrity.

4) Fuel requirements for electricity or shipping, as well as public procurement, can generate initial demand and increase output.

For developers and banks, private financing and offtake agreements (such as those for the purchase of power and ammonia) further reduce project risk.

265.7) Emerging Trends & Technologies

1) Modular and low-temperature synthesis: Smaller-scale, dispersed green ammonia plants could be made possible by new synthesis techniques that operate flexibly alongside renewable energy sources.

2) Co-locating solar and wind energy with electrolysis to save costs and maximise local value is known as integrated renewables + electrolysers.

3) Technologies that burn or convert ammonia more efficiently and cleanly are developing, such as dual-fuel engines and ammonia fuel cells.

4) In order to make projects financially feasible, hybrid business models combine local fertiliser demands with export markets.

265.8) What success looks like?

The following will indicate the widespread use of green ammonia:

1) Due to declining renewable energy and electrolyser costs, large-scale projects are approaching or surpassing the cost of fossil ammonia.

2) Trading in certified low-carbon ammonia with strong origin guarantees on a global scale.

3) Established environmental and safety regulations, as well as an advanced infrastructure for storage and bunkering.

4) Increased usage of ammonia for long-term storage and marine fuel, decreased industrial emissions, and decarbonised fertiliser supply chains.

265.9) Conclusion

Green ammonia is at the nexus of international trade, industrial decarbonisation, and renewable energy. Although there are technical, financial, and safety challenges, it provides a workable way to store and transfer renewable energy on a large scale and decarbonise industries that would otherwise be challenging to electrify. Green ammonia could be a key component of a net-zero energy system with focused legislative support, investments in electrolyser production and synthesis innovation, and strict safety and certification regimes.
