Green Ammonia Stocks: 2026 Watchlist

Green ammonia stocks are an early-stage investment theme, not a mature stock category. As of August 2026, the clearest public-market exposure comes from ammonia producers, owners of renewable-ammonia projects, and electrolyzer suppliers. The six companies below—Yara International, Fertiglobe, Air Products, Acwa, thyssenkrupp nucera, and Nel—have verifiable exposure, but none offers a guaranteed return or a pure, low-risk bet on green ammonia. If you are looking at ammonia stocks more broadly, the largest listed producers are conventional rather than green, and no listed company is a pure-play ammonia fuel cell stock. Both groups are covered further down.

Last reviewed: August 21, 2026. This watchlist does not include live share prices because prices, valuation multiples, exchange access, and project schedules change frequently. Market values quoted in the comparison tables below were retrieved on August 21, 2026. This update added sections on ammonia fuel cell stocks and on the largest conventional ammonia producers, and refreshed the Fertiglobe ownership, NEOM schedule, and OCI disclosures.

Investment risk disclosure: This article provides general research, not individualized financial advice. Stocks can lose value, and foreign shares may add currency, liquidity, custody, tax, and political risks. Review current regulatory filings and consider qualified professional advice before investing.

Key takeaways

• There are few mature, publicly traded pure-play green ammonia companies.
• Yara and Fertiglobe provide the most direct producer exposure in this watchlist.
• Air Products and Acwa own stakes in the NEOM Green Hydrogen Project, which was 90% complete in March 2026 and is targeting first product availability in 2027.
• thyssenkrupp nucera and Nel are electrolyzer suppliers. Their revenue depends on equipment orders and project execution rather than the ammonia selling price alone.
• Green ammonia is not the same as CCS-based low-carbon or blue ammonia. Investors should verify the hydrogen source, electricity source, lifecycle boundaries, certification, and residual emissions.
• This is a research watchlist, not a ranking by expected return.

Green ammonia stock comparison

Company	Primary listing	Exposure type	Current evidence	Main risk
Yara International	Oslo: YAR	Producer and distributor	Operating renewable-hydrogen and ammonia production at Herøya	Renewable ammonia remains small relative to its conventional fertilizer business
Fertiglobe	ADX: FERTIGLB	Producer and project developer	Certified renewable-ammonia activity and long-term H2Global-supported Egypt project	Development-stage scale-up, majority-owner control and limited foreign-market access
Air Products	NYSE: APD	Project owner, integrator and offtaker	One-third owner and sole offtaker for the NEOM renewable-ammonia project	Megaproject execution, capital allocation and commercialization risk
Acwa	Saudi Exchange: 2082	Project owner and developer	One-third NEOM ownership and development exposure	Foreign-market access, currency exposure and large-project concentration
thyssenkrupp nucera	Frankfurt: NCH2	Electrolyzer supplier	Contracted to supply more than 2 GW of electrolyzer capacity for NEOM	Negative earnings, uneven project timing and indirect ammonia exposure
Nel	Oslo: NEL	Electrolyzer supplier	Supplied 10 MW of capacity to an operating dynamic green-ammonia plant in Denmark	Losses, order volatility and smaller project scale

The table intentionally separates producers from project owners and equipment suppliers. A supplier can benefit from construction spending without receiving ammonia-market margins. A producer can sell ammonia but may still derive most of its earnings from conventional natural-gas-based fertilizer.

How the stocks were selected

Each company had to meet three basic requirements: publicly traded common equity, current evidence of green-ammonia exposure, and sufficient public disclosure to evaluate the exposure. Private companies and businesses connected only through broad hydrogen narratives were excluded from the core list.

Project evidence was weighted in the following order:

1. Operating production and customer deliveries
2. Commissioning or advanced construction with financing in place
3. Final investment decision and binding offtake
4. Contracted equipment supply for a financed project
5. FEED studies, demonstrations and pilot facilities
6. MOUs, targets and unfinanced project announcements

This hierarchy matters because the low-emissions hydrogen sector has repeatedly experienced delayed final investment decisions, resized facilities and cancelled projects. Readers comparing this theme with broader green hydrogen stocks should apply the same evidence standard.

Six green ammonia stocks to research

1. Yara International (Oslo: YAR)

Yara provides the most direct operating exposure among the larger listed companies in this watchlist. In June 2024, it opened a 24 MW renewable-hydrogen plant at Herøya, Norway. The hydrogen is produced through water electrolysis using renewable electricity and feeds Yara’s existing ammonia-production system.

Yara also has an established ammonia shipping, terminal and distribution network through Yara Clean Ammonia. That infrastructure may be as important as production because emerging renewable-ammonia projects need storage, transport, certification and customers.

Investors should still separate Yara’s renewable projects from its broader ammonia portfolio. In June 2026, Yara declined to proceed with the Louisiana Clean Energy Complex transaction because expected returns did not meet its criteria. Days later, it agreed to acquire a conventional Gulf Coast ammonia plant. The latter may strengthen Yara’s ammonia platform, but it should not be counted as green-ammonia production.

• Why it qualifies: Operating renewable-ammonia production and established global logistics.
• What to monitor: Renewable-ammonia sales volumes, premiums, third-party distribution agreements and the proportion of capital allocated to genuinely renewable projects.
• Primary risk: Most current earnings still depend on conventional nitrogen fertilizer, natural-gas economics and agricultural cycles.

2. Fertiglobe (ADX: FERTIGLB)

Fertiglobe is a listed nitrogen-fertilizer and ammonia producer controlled by ADNOC, which raised its holding to 86.2% when it completed its purchase of OCI’s majority stake on October 15, 2024. That leaves a 13.8% free float on the Abu Dhabi Securities Exchange. Its investment case is more direct than that of a generic renewable-energy company because it already owns ammonia assets and is developing renewable and lower-carbon ammonia supply.

The company reports that its Egypt Green project has produced certified renewable ammonia using renewable hydrogen. Fertiglobe also won an H2Global auction to supply renewable ammonia to Europe. That award provides more commercial evidence than an unsupported MOU because it introduces long-term demand and pricing support.

However, demonstration cargoes do not prove that a large new facility will be completed on schedule or produce acceptable shareholder returns. Investors should follow the Egypt project’s financing, final investment decision, construction timetable, contracted minimum volumes and production costs.

• Why it qualifies: Existing ammonia assets, certified renewable-ammonia experience and supported European offtake.
• What to monitor: Egypt Green FID, commissioning dates, required capital and contracted delivery milestones.
• Primary risk: Development-stage execution plus a relatively small public free float and more complicated ADX market access for some foreign investors.

3. Air Products (NYSE: APD)

Air Products offers US-listed exposure to one of the world’s largest renewable-ammonia developments. It is an equal owner of NEOM Green Hydrogen Company with Acwa and NEOM, acts as the project’s system integrator, and is the sole offtaker for up to 1.2 million metric tonnes of renewable ammonia per year.

In March 2026, NEOM Green Hydrogen Company reported that construction was 90% complete across its sites. The project is designed to combine up to 4 GW of wind and solar generation with large-scale electrolysis, nitrogen separation and ammonia synthesis. It reached financial close in May 2023 at a total investment value of $8.4 billion, and Air Products holds the offtake for more than 30 years. Its solar and wind generation is more than 95% complete, and first ammonia is expected in 2027, with production targeted for the middle of that year.

This is stronger evidence than an early-stage project announcement, but it remains a complex megaproject. Commercial success depends on commissioning, plant reliability, shipping, conversion of ammonia back to hydrogen where required, customer demand and the price buyers will pay for verified renewable supply.

• Why it qualifies: Direct project ownership, integration responsibility and contracted offtake at industrial scale.
• What to monitor: Commissioning milestones, first production, customer contracts, realized margins and the final marketing arrangement with Yara.
• Primary risk: Megaproject delays, cost overruns, capital-allocation changes and uncertain end-market economics.

4. Acwa (Saudi Exchange: 2082)

Acwa, formerly branded ACWA Power, owns another one-third of NEOM Green Hydrogen Company. Its exposure differs from Air Products because Acwa’s primary role is infrastructure development and project ownership rather than exclusive global offtake.

The company’s NEOM project disclosure describes a facility designed to produce 600 tonnes of renewable hydrogen per day and up to 1.2 million tonnes of renewable ammonia per year when commissioned. Acwa also has renewable-power, desalination and infrastructure experience that may support execution across integrated hydrogen projects.

The investment case is not limited to one ammonia plant, which provides diversification but also dilutes the effect that renewable-ammonia growth may have on group earnings. Non-Saudi investors must also confirm that their broker supports the Saudi Exchange and understand applicable ownership, currency, settlement and tax rules.

• Why it qualifies: Equity ownership and development responsibility in an advanced, financed renewable-ammonia project.
• What to monitor: NEOM commissioning, project-level cash flow, additional financed ammonia projects and debt requirements.
• Primary risk: Foreign-market access, currency exposure, capital-intensive development and limited earnings materiality from a single project.

5. thyssenkrupp nucera (Frankfurt: NCH2)

thyssenkrupp nucera is an equipment-enabler investment rather than an ammonia producer. Air Products contracted the company to provide more than 2 GW of alkaline electrolysis capacity for NEOM. That is a material industrial reference project for large-scale renewable-hydrogen equipment.

A supplier can earn revenue during project engineering, manufacturing and installation without owning the ammonia commodity. The tradeoff is that revenue may be uneven and dependent on customers reaching FID. A large announced project pipeline does not become revenue until contracts are signed and milestones are completed.

In its May 2026 results, nucera reported sharply higher order intake, but sales declined and management continued to forecast negative full-year EBIT. Investors therefore need to evaluate both technology demand and the company’s ability to convert backlog into profitable revenue.

• Why it qualifies: Direct equipment contract for a major renewable-ammonia facility.
• What to monitor: Green-hydrogen order intake, backlog conversion, gross margin, customer FIDs and service revenue.
• Primary risk: Negative earnings, project delays, customer concentration and indirect exposure to ammonia selling prices.

6. Nel (Oslo: NEL)

Nel is another electrolyzer supplier with direct evidence from an operating ammonia facility. It supplied four alkaline units totaling 10 MW to the dynamic green-ammonia plant at Ramme, Denmark. The plant integrates wind and solar electricity and adjusts production as renewable output changes.

The project is much smaller than NEOM, but it provides useful operating evidence. It demonstrates that electrolyzers and ammonia synthesis can be integrated with variable renewable generation rather than relying only on a theoretical design or an unfinanced announcement.

Nel remains financially risky. Its fourth-quarter 2025 results showed lower year-over-year revenue, negative EBITDA and a large net loss that included asset impairments. The company maintained cash and reported stronger sequential order intake, but investors should not treat technology validation as proof of near-term profitability.

• Why it qualifies: Electrolyzer technology operating inside a renewable-ammonia facility.
• What to monitor: New firm orders, cash use, manufacturing utilization, margins and larger ammonia-related contracts.
• Primary risk: Continued losses, financing needs, order volatility and comparatively small ammonia-project exposure.

What is green ammonia?

Ammonia is a compound of nitrogen and hydrogen with the chemical formula NH3. The final molecule is chemically identical regardless of how it was produced. The terms green, renewable, blue, low-carbon and grey describe the energy, hydrogen feedstock and emissions associated with production—not different types of NH3.

Production label	Typical hydrogen route	Production-emissions profile	What investors should verify
Green or renewable ammonia	Water electrolysis powered by renewable electricity	Potentially very low, subject to electricity sourcing and full lifecycle boundaries	Renewable-power source, grid treatment, additionality, certification and lifecycle intensity
Blue or CCS-based low-carbon ammonia	Natural-gas-based hydrogen with carbon capture and storage	Lower than conventional production, but residual process emissions and upstream methane emissions remain	Capture rate, actual storage, methane leakage, system boundaries and certification method
Grey or conventional ammonia	Natural-gas- or coal-based hydrogen without carbon capture	High direct fossil-fuel emissions	Feedstock cost, plant efficiency and exposure to future carbon costs

The International Renewable Energy Agency has estimated that renewable hydrogen represents more than 90% of renewable-ammonia production cost. Electricity price, electrolyzer utilization, financing cost and plant scale therefore have a major effect on commercial viability.

Readers who need broader context on electrolyzers, hydrogen carriers and industry economics can review this guide to how to invest in hydrogen.

Why green ammonia stocks remain high risk

The industry’s long-term use cases are credible, but current commercial scale remains limited. The International Energy Agency reported that low-emissions hydrogen still represented less than 1% of global hydrogen production in 2024. Projects that were operating or had reached FID were expected to reach 4.2 million tonnes per year by 2030—well below the ambitions announced earlier in the decade.

• Offtake and pricing risk: Producers need customers willing to sign long-term contracts or pay a premium over conventional ammonia. A project can be technically viable but financially unbankable without reliable demand.
• Renewable-power risk: Electrolyzers require large amounts of low-cost electricity. Grid congestion, curtailment rules, transmission delays and weak renewable resources can change project economics.
• FID and construction risk: MOUs and FEED studies are not funded plants. Investors should distinguish preliminary announcements from permits, debt commitments, equity funding, EPC contracts and binding offtake. In 2026 Topsoe ended its supply agreements with First Ammonia, which had covered 100 MW of solid oxide electrolyser modules for a Texas green-ammonia project, showing that even signed equipment deals can be unwound.
• Safety and regulatory risk: Ammonia is toxic. Storage, bunkering and maritime use require leak detection, ventilation, containment, trained personnel and emergency systems. The International Maritime Organization’s interim ammonia-fuel guidelines reflect these operational requirements.
• Classification risk: Companies often use broad terms such as clean, low-emission or low-carbon ammonia. Those labels may include CCS-based production rather than renewable electrolysis.
• Commodity exposure: Established producers remain affected by natural-gas prices, agricultural demand, fertilizer supply and global trade even when they develop renewable projects.
• Financing and dilution risk: Early-stage developers may repeatedly issue shares before achieving commercial revenue. Large facilities also depend on complex sustainable finance, subsidies, guarantees and long-term contracts.
• Opportunity-cost risk: Investors may obtain cleaner or less project-dependent exposure through diversified renewable energy stocks.

Why common green ammonia stock lists are outdated

Several companies commonly included in older green-ammonia lists no longer belong in a core, current watchlist. Some remain relevant as speculative or adjacent ideas, but their status needs accurate labeling.

Company	Current status	Editorial treatment
CF Industries	Its 2025 annual report says the company abandoned its 20 MW Donaldsonville electrolyzer project after determining that additional investment would not produce an acceptable return. It now prioritizes CCS-based low-carbon ammonia.	Relevant to low-carbon ammonia, but no longer a core green-electrolysis pick.
FuelPositive	Developing and commissioning an on-farm demonstration system rather than operating a mature commercial fleet.	Potentially direct but highly speculative; verify filings, funding, commissioning and customer evidence.
AmmPower	The Canadian Securities Exchange suspended trading in October 2025 following a cease-trade order.	Exclude from a current investable core list unless the exchange confirms that the suspension has been lifted.
Topsoe	A major ammonia-technology provider, but its common equity is privately owned and unlisted.	Important industry entity, not a directly purchasable public stock.
Ballard Power Systems	Its fuel cells can be paired with systems that crack ammonia into hydrogen, but Ballard does not produce green ammonia.	Ammonia-to-power adjacency rather than direct ammonia exposure.
Iberdrola	Operates renewable-hydrogen assets that can feed ammonia production, including the Puertollano project in Spain.	Legitimate but highly diluted exposure within a much larger utility business.

CF Industries is the clearest example of why current filings matter. Earlier announcements described a green-ammonia electrolyzer, but the company’s subsequent annual report disclosed that commissioning had been suspended and the project abandoned. Investors should give audited filings and current exchange notices greater weight than recycled company lists.

Are there any ammonia fuel cell stocks?

No listed company is a pure-play ammonia fuel cell stock as of August 2026. Most fuel cells cannot run on ammonia directly. The ammonia is first cracked back into hydrogen, and the cell then runs on that hydrogen. So the listed exposure sits with hydrogen fuel cell makers whose systems can be fed by cracked ammonia, plus one micro-cap with an ammonia-to-power product line. The companies furthest along in ammonia cracking itself are private.

This distinction matters because searches for ammonia fuel cell companies often return general hydrogen fuel cell businesses. Their revenue depends on hydrogen system sales, not on ammonia volumes or ammonia pricing.

Company	Listing	What it actually sells	Strength of the ammonia link
GenCell	Tel Aviv: GNCL	Alkaline fuel cell backup power for telecom, utilities and off-grid sites, including an ammonia-to-power line that cracks ammonia on site	Closest to a listed ammonia fuel cell stock, but a micro-cap: market value near $8 million and trailing twelve-month revenue of $1.91 million to December 31, 2025
Ballard Power Systems	Nasdaq: BLDP	Proton exchange membrane hydrogen fuel cells for bus, truck, rail and marine use	Indirect. Ammonia is only a possible upstream hydrogen carrier; Ballard sells no ammonia product. Market value about $754 million
Ceres Power	London: CWR	Licensed solid oxide fuel cell and electrolyser technology, manufactured by partners	Indirect and upstream. Its electrolysers can make hydrogen that feeds ammonia synthesis; the cells are not ammonia-fed. Signed a multi-gigawatt fuel cell partnership with Centrica in March 2026
Amogy	Private	Ammonia cracking and power systems aimed at shipping and heavy transport	Direct, but not purchasable. Still privately held as of 2026
Topsoe	Private	Ammonia synthesis and cracking technology, plus solid oxide electrolysers	Direct, but not purchasable. In 2026 it ended its supply agreements with First Ammonia, which had covered 100 MW of electrolyser modules for a Texas green-ammonia project

The Topsoe cancellation is a useful warning. A named technology supplier and a signed agreement are not the same as a plant that gets built, and ammonia-cracking demand has repeatedly arrived later than announced.

Which ammonia stocks are the largest listed producers?

The largest publicly traded ammonia companies are conventional producers, not green ones. Nutrien, CF Industries, Yara and LSB Industries make ammonia at industrial scale from natural gas, and together they account for most of the listed market value in ammonia. A search for ammonia stocks will usually surface these names; a search for green ammonia stocks will not, because their renewable production is small or absent.

Company	Listing	Ammonia position	Market value	Green ammonia status
Nutrien	NYSE and TSX: NTR	World’s third-largest nitrogen producer, with gross ammonia capacity above 7 million tonnes and more than 11 million tonnes of total nitrogen products across the US, Canada and Trinidad	$33.6 billion	Conventional. No operating renewable-ammonia production disclosed
CF Industries	NYSE: CF	Largest global ammonia producer; reported first-half 2026 net earnings of $1.34 billion, or $8.71 per diluted share	$18.0 billion	Abandoned its 20 MW Donaldsonville electrolyser and now prioritises carbon-capture-based low-carbon ammonia
Yara International	Oslo: YAR; US OTC ADR: YARIY	Global ammonia producer with its own shipping, terminal and distribution network	Not quoted here; Oslo-listed in Norwegian kroner	The strongest of this group. Operates a 24 MW renewable-hydrogen plant at Herøya feeding existing ammonia synthesis
LSB Industries	NYSE: LXU	Pure-play North American nitrogen producer with roughly 875,000 tonnes of gross ammonia capacity a year	$747 million	Conventional, with low-carbon ammonia ambitions rather than operating renewable production
OCI Global	Euronext Amsterdam: OCI	Sold OCI Ammonia Holding, including its Rotterdam import and storage terminal and its ammonia distribution business, to AGROFERT for €290 million on March 31, 2026	Not quoted here	Largely exited. European Nitrogen is the main remaining business, so OCI no longer offers the ammonia exposure older lists describe

Buying these companies is mostly buying natural gas economics and agricultural demand. Their earnings rise and fall with gas prices, fertiliser spreads and crop cycles rather than with progress on renewable hydrogen. That can be an attractive business, but it is a different investment from the one most people mean by green ammonia.

OCI is the clearest example of why an ammonia list needs re-checking. It appears in many older ammonia stock articles as a major producer, and it has since sold the terminal and distribution assets that justified the description.

How to evaluate a green ammonia stock

1. Identify the production route. Confirm whether the project uses renewable electrolysis, conventional fossil hydrogen, or fossil hydrogen with CCS.
2. Verify the project stage. Look for operating output, commissioning, construction progress, FID, permits and financing—not only targets or MOUs.
3. Examine the offtake. Determine whether buyers have signed binding contracts, how long those contracts last and whether pricing support depends on subsidies.
4. Measure financial materiality. A billion-dollar project can still be immaterial to a diversified multinational. Compare the company’s ownership percentage, expected capital contribution and prospective revenue with the rest of the business.
5. Review project economics. Evaluate renewable-power cost, electrolyzer utilization, financing, construction budget, transport, storage and conversion costs.
6. Check the balance sheet. Review cash, debt, free cash flow, share issuance, operating losses and the amount of capital needed before commercial production.
7. Check the listing and liquidity. Confirm the primary exchange, trading currency, average liquidity, foreign-ownership rules, custody costs and availability through your broker.

An ESG stock screener can help compare emissions, controversies and governance, but it cannot replace project-level due diligence. Green-ammonia labels should always be tested against primary disclosures.

How to buy green ammonia stocks

The companies in this watchlist trade across the New York Stock Exchange, Oslo Stock Exchange, Abu Dhabi Securities Exchange, Saudi Exchange and Frankfurt Stock Exchange. Market access depends on your country and broker.

1. Confirm that your brokerage account supports the company’s primary exchange.
2. Check whether an ADR or OTC instrument exists, then compare its liquidity, fees and conversion terms with the ordinary shares.
3. Review foreign-exchange costs, withholding taxes, custody fees and local reporting obligations.
4. Use limit orders for less-liquid foreign shares rather than assuming the displayed quote is executable.
5. Read the latest annual report, interim results, project disclosures and exchange notices before entering a position.
6. Set position size according to project, liquidity and loss risk rather than the strength of the industry narrative.

Green ammonia can form part of a broader sustainable investing process, but many established ammonia companies still consume substantial natural gas. Investors seeking strict fossil-fuel exclusion should compare these holdings with the criteria used by fossil-fuel-free funds.

Are green ammonia stocks worth researching?

Green ammonia is worth researching as a long-term industrial-decarbonization theme, but it is not yet a mature standalone stock category. Yara and Fertiglobe offer the clearest producer exposure in this watchlist. Air Products and Acwa provide ownership exposure to a major construction-stage project. thyssenkrupp nucera and Nel are equipment suppliers whose outcomes depend on hydrogen-project orders and execution.

The practical approach is to treat these companies as a watchlist rather than an automatic buy list. Verify the production route, project stage, offtake, financing, materiality and balance sheet before comparing valuations.
