When you optimize every step, the costs drop dramatically.
In the long human effort to reconcile industrial civilization with a livable climate, a new analysis from Mitsubishi Heavy Industries offers a measured but meaningful signal: green ammonia produced in India, where renewable energy is among the world's cheapest, could become a cost-competitive fuel for Asia if the full chain of production, transport, and use is treated as a single coordinated system rather than a collection of separate transactions. The study, conducted under a Japanese government cooperation program and anchored by a planned 1.1-million-ton facility in Odisha, does not promise transformation—it maps the conditions under which transformation becomes possible. What remains is the harder work: persuading governments and industries across borders to act in concert before the window of climate urgency closes.
- Green hydrogen and ammonia have long been promised as climate solutions, but their costs have stubbornly resisted the economics needed to make them real—this study directly confronts that barrier.
- India's exceptionally cheap renewable energy gives it a structural advantage as a green fuel producer, and a 1.1-million-ton ammonia project in Odisha is already moving from concept toward construction.
- Mathematical modeling of the full value chain—factories, ships, storage, operational timing—revealed that coordinated optimization across companies, not just within them, could unlock dramatic cost reductions.
- The analysis exposes a critical gap: without government action to create real demand, reduce capital costs, and establish regulatory frameworks, the economics remain theoretical rather than investable.
- Mitsubishi Heavy is now in active dialogue with both Indian and Singaporean governments, framing this study not as a conclusion but as the opening move in building a functioning regional green fuel market.
Mitsubishi Heavy Industries released findings this week suggesting that green ammonia produced in India could become cost-competitive across Asia—but only if the entire supply chain, from production through shipping to final use, is treated as one coordinated system rather than a series of independent steps. The analysis was conducted under a Japanese government program focused on economic cooperation across the Global South, and examined a specific corridor: ammonia made from Indian renewable energy, transported to Singapore for power generation and marine fuel.
The central insight is that optimization across the whole value chain—timing production to match seasonal wind and solar output, coordinating shipping and storage schedules, aligning operations between separate companies—can drive costs down substantially. India's renewable energy is already among the cheapest in the world, giving it a structural edge as a green fuel producer. Mitsubishi Heavy worked with Hygenco, which is developing a green ammonia facility on India's east coast in Odisha with an eventual capacity of 1.1 million tons per year, using mathematical modeling to identify where savings could be found.
Yet the study is equally candid about what remains unbuilt. Governments in both India and Singapore must move beyond theoretical markets and create genuine demand for green ammonia, reduce the upfront capital burden of new facilities, support technology development, and establish frameworks for valuing the climate benefit of cleaner fuels. Mitsubishi Heavy has already begun presenting both governments with specific proposals—how to structure incentives, where to invest, how to assess whether green fuel premiums are justified.
The company is positioning itself as a bridge between policy ambition and commercial reality. It describes the next phase as less about analysis and more about negotiation—securing commitments from governments and businesses to the interlocking pieces that make a regional green fuel market function. This study, in that framing, is not a destination but an opening move in a longer effort to decarbonize energy trade across Asia.
Mitsubishi Heavy Industries released findings this week suggesting that green ammonia produced in India could become a cost-competitive fuel source for neighboring countries if the entire supply chain—from production through transportation to final use—is carefully orchestrated. The company conducted the analysis under a Japanese government program aimed at fostering economic cooperation across the Global South, examining a specific scenario: ammonia made from renewable energy in India, then shipped to Singapore for use in power generation and as marine fuel.
The core finding is straightforward but consequential. When you optimize every step of the journey—the factories that produce the ammonia, the ships that carry it, the storage facilities, the timing of operations—the costs drop dramatically. This matters because green ammonia and hydrogen have become central to how countries plan to meet climate commitments, yet the expense of scaling them up has remained a stubborn barrier. India holds a particular advantage: its renewable energy is already among the world's cheapest, which means the raw material for making green fuels costs less there than almost anywhere else.
Mitsubishi Heavy worked with Hygenco, an Indian developer building a green ammonia facility on the country's east coast in Odisha, which will eventually produce 1.1 million tons annually. The company used mathematical modeling to test different configurations of the entire value chain, asking: where can we cut costs? What if we time production to match seasonal swings in wind and solar output? What if shipping and storage operators coordinate their schedules? The analysis revealed that cooperation between businesses across the chain—not just within a single company—could unlock substantial savings.
But the study also identified what remains undone. Governments in India and Singapore need to create actual demand for green ammonia, not just theoretical markets. They need to lower the upfront capital costs of building new facilities. They need to fund technology development and establish frameworks for pricing the climate benefit of green fuels. Mitsubishi Heavy has already begun conversations with both governments, laying out a roadmap for what a functioning regional market would require.
The company is positioning itself as a bridge between policy and business. It has proposed specific measures to both nations: how to structure incentives, where to invest in infrastructure, how to evaluate whether the premium customers pay for green fuel is justified. The next phase is less about analysis and more about negotiation—getting governments and companies to commit to the pieces that make the whole system work. Mitsubishi Heavy says it will continue those discussions, signaling that this is not a one-time study but the opening move in a longer effort to build a decarbonized fuel trade across Asia.

The Hearth Conversation Another angle on the story
Why does India matter so much for this? Couldn't green ammonia be made anywhere?
India's renewable energy is already the cheapest in the world. That's not a future promise—it's happening now. So the raw material cost is lower there than almost anywhere else. That's the foundation.
But shipping ammonia across the ocean seems expensive. Doesn't that eat into the savings?
It does, which is why the whole value chain has to be optimized together. If you time production to match when renewable energy is abundant, coordinate storage and shipping schedules, and have buyers ready on the other end, the transportation cost becomes manageable.
So this only works if India and Singapore actually cooperate?
Exactly. A single company can't do this alone. You need governments to create demand, reduce capital costs, and set up the right rules. Mitsubishi Heavy did the math to show it's possible. Now they're trying to convince the governments it's worth doing.
What happens if they don't cooperate?
The cost advantage disappears. You're back to expensive green ammonia that can't compete with fossil fuels. The whole point is that India's cheap renewable energy only matters if you can actually use it at scale.
Is this just about Singapore, or could it spread?
Singapore is the test case. But if it works there, the model could apply to other countries in Asia that need decarbonized fuel. That's the real prize.
