Green Ammonia in Bangladesh: What It Takes to Build a Plant

Ammonia sits at the heart of Bangladesh’s food and energy story: it is a key ingredient for urea fertiliser and is now emerging worldwide as a clean fuel and hydrogen carrier. Bangladesh already operates several large gas-based fertiliser plants, but a new wave of interest is forming around green ammonia produced from renewable electricity rather than natural gas.
The government has also signalled plans to use hydrogen and ammonia for power generation by around 2035 and to reach 40 percent of electricity from clean energy by 2041, which creates a natural policy window for green ammonia projects.
Why Green Ammonia Matters Now
Today, almost all ammonia in Bangladesh and globally is grey, made from natural gas via steam methane reforming and the Haber-Bosch process, which emits large amounts of carbon dioxide. This path has supported fertiliser production for decades but is vulnerable to gas price volatility, declining gas fields, and growing climate pressure.
Green ammonia instead uses only water, air, and renewable electricity as inputs. Electricity powers electrolysers to produce hydrogen from water and air-separation units to extract nitrogen from air; the two are then combined in a Haber-Bosch synthesis loop. When the electricity is truly renewable, process emissions can be close to zero.
Globally, green ammonia is still a small share of the market and remains more expensive than fossil-based ammonia, but costs are expected to fall as electrolysers and renewables scale up. For Bangladesh, early projects could serve domestic fertiliser demand, help decarbonise a portion of power generation, and potentially open an export channel for low-carbon fuels over time.
Bangladesh’s Starting Point
Bangladesh already hosts several large ammonia-urea complexes built around domestic natural gas. One example is the Polash fertiliser plant, designed to produce about 1,600 tonnes per day of ammonia and 2,800 tonnes per day of urea using local gas. Studies on plants such as Ashuganj show that as gas quality changes, maintaining the right hydrogen-to-nitrogen ratio requires higher gas consumption, increasing both costs and pressure on limited gas reserves.
At the same time, the country’s renewable energy deployment remains modest. This combination of strong fertiliser demand, gas constraints, and long-term clean-energy goals makes Bangladesh an interesting but challenging candidate for early green ammonia projects.
How a Green Ammonia Plant Works
A green ammonia plant keeps the same final synthesis step as a conventional ammonia plant but replaces fossil-based hydrogen with green hydrogen from electrolysis and powers all major units with renewable electricity.
- Hydrogen production: Electrolysers split purified water into hydrogen and oxygen using electricity.
- Nitrogen production: Air-separation units or PSA systems isolate high-purity nitrogen from air.
- Haber-Bosch synthesis: Hydrogen and nitrogen are reacted over an iron-based catalyst at high pressure and temperature to form ammonia.
Research on fully electrified e-ammonia plants suggests that this configuration can cut lifecycle emissions significantly compared to traditional gas-based plants when powered by renewable energy.
Key Requirements for a Green Ammonia Plant in Bangladesh
1. Abundant, low-cost renewable electricity
Electricity cost and availability are the biggest drivers of green ammonia economics. A viable project would likely need large-scale dedicated solar and or wind projects, possibly with storage, plus long-term tariff certainty through PPAs or integrated plant ownership.
2. Water supply and land
Electrolysis needs high-purity water and a reliable source of supply. Bangladesh’s dense land use also means site selection is critical, especially for a project that combines utility-scale renewables, industrial processing units, storage, and safety buffer zones.
3. Electrolysers, air separation, and the ammonia loop
A developer must integrate electrolysers, nitrogen production, and the ammonia synthesis loop in a way that can handle variable renewable power without excessive cycling or efficiency losses.
4. Storage, safety, and logistics
Because ammonia is toxic and corrosive, storage requires strict design codes, inspection, gas detection, and emergency planning. A Bangladeshi green ammonia plant would also need strong trucking, pipeline, or export-port logistics depending on its end market.
5. Policy, permits, and environmental safeguards
Environmental impact assessments, hazardous-chemical compliance, and clear renewable-linked policy incentives are essential. For truly green ammonia, incentives must support renewable-based production rather than fossil-heavy co-firing projects.
6. Financing, partnerships, and off-take
Because green ammonia is still costlier than conventional ammonia, early projects will likely need strategic technology partners, long-term off-take agreements, and concessional or blended finance support.
Where Green Ammonia Fits in Bangladesh’s Future
If designed well, a green ammonia plant in Bangladesh could support three transitions at once: lower-emission food security by replacing grey ammonia in fertiliser, cleaner power and industry through carefully targeted pilot uses, and export diversification into low-carbon fuels.
To succeed, projects must be genuinely renewable-powered, carefully sited around water and land realities, and embedded in an energy roadmap that prioritises solar, wind, and other renewables over fossil-heavy transition pathways. Done right, green ammonia could become one of the most strategic industries in Bangladesh’s next energy chapter.
