Top Green Hydrogen Stocks 2026: Hype Died, Orders Didn't

Green hydrogen in one sentence: take water, zap it with cheap solar or wind, and out comes hydrogen with zero carbon attached.

That hydrogen can replace the dirty stuff refineries and fertilizer plants already burn through by the millions of tonnes. It can turn iron ore into steel without coal. It can become ammonia and get shipped across an ocean.

Sounds amazing. It is amazing. And the chemistry works. The problem is green hydrogen still costs roughly 2-4x what "grey" hydrogen from natural gas costs, and nobody wants to be the first customer to pay the difference.^[1]

So in 2021, everyone promised gigawatts. In 2023-2025, everyone quietly cancelled them. Rhodium Group counts $9 billion in U.S. cancellations since 2018, and only $5 billion actually invested out of $63 billion announced. Zero new U.S. projects were announced in Q1 2026. Cummins halted all new electrolyzer sales in February and took $458 million in charges. Topsoe paused its Virginia factory.

And the U.S. tax credit (45V, worth up to $3/kg) now requires construction to start by December 31, 2027 instead of 2033.

The hydrogen bubble popped. What's left is a small, real business with a big, real order book problem: plenty of demand for subsidies, not enough demand for hydrogen.

So here's where the theme still lives on:

Europe has kept writing checks. The third European Hydrogen Bank auction handed €1.09 billion to nine projects (about 1.1 GW) in May, and it was oversubscribed six times over. Germany put up another €1.3 billion on top. The EU's carbon border tax (CBAM) is now live on steel, cement, aluminum and fertilizer imports, which quietly makes clean hydrogen more competitive inside Europe.

And the order books at the surviving electrolyzer makers turned around. Nel's Q2 order intake was up 224%. thyssenkrupp nucera nearly doubled its nine-month intake. ITM raised guidance. Plug's gross margin went from -31% to breakeven in a year.

The theme isn't dead. But it's been shrunk to the projects that have real customers, real subsidies, and cheap power. Think Europe, the Middle East, India. Not Texas.

We slice it into three buckets:

1. Pure-plays – electrolyzer makers. Live or die on green hydrogen.
2. Integrated – giants where hydrogen is one line item. Safer, but you're mostly buying something else.
3. The China Factor – the low-cost manufacturers rewriting the price sheet for everyone.

Plus two private companies to watch even though you can't buy them yet.

These companies make the machines that split water. When a project gets funded, they get an order. When a project gets cancelled, they get a write-down. Every one of them loses money today. The question is who runs out of runway first.

Nel ASA OSE: NEL

Nel is the oldest name in the business (its alkaline tech traces back to Norwegian hydropower in the 1920s) and it's living a split-screen life right now.

The good screen: Q2 order intake hit NOK 230 million, up 224% year-over-year, almost all of it PEM electrolyzers. Backlog is NOK 1.2 billion. On May 6 they launched the PA-Series, a pressurized alkaline platform that's supposed to cut a project's upfront cost and footprint. They've started building a 1 GW production line for it at Herøya and licensed the tech to Reliance for a gigafactory in India, so somebody else pays for that scale.

The bad screen: revenue fell 12% to NOK 153 million, the net loss widened to NOK 189 million (including a NOK 70 million legal settlement with Iwatani), and cash is down to NOK 1.3 billion from NOK 1.9 billion a year ago. The CEO resigned and the search is still open. The stock sits about 46% below its May peak.

If the PA-Series wins even a couple of the EU auction projects, Nel is the cheapest way to own that. Watch the Q3 report on October 21 for whether orders are turning into revenue.

ITM Power LSE: ITM

ITM is the quiet one. Sheffield, England. PEM electrolyzers. Twenty-five years of R&D that mostly went nowhere until a new CEO cleaned house in 2023.

The turnaround numbers are real: record half-year revenue of £18 million, full-year guidance raised to £40-43 million, and a £152 million backlog where 71% of contracts are actually profitable (the other 29% are legacy deals they're grinding through). Cash is £198 million and barely moving, down only £9 million in twelve months. In this sector that's a superpower.

Then in April the UK government showed up. Great British Energy is putting £40 million in equity and DESNZ is granting £46.5 million to build a 1 GW manufacturing line for ITM's next-gen "Chronos" stack. Add the 710 MW of German projects it was selected for by Stablegrid, and the RWE plant in Germany that just delivered its first green hydrogen in August, and you've got a company with a government backstop and a European customer base.

It's still losing £27-29 million a year at the EBITDA line. Full-year results land September 15.

thyssenkrupp nucera ETR: NCH2

thyssenkrupp nucera has a trick the others don't: a second business that makes money. Its chlor-alkali electrolysis unit (same core tech, different chemistry, used by the chemicals industry) did €109 million in Q3 sales and €15 million EBIT.

The green hydrogen side is lumpy. Nine-month order intake nearly doubled to €471 million, driven by the 300 MW Onuba project with Moeve in Spain (plus an 8-year, €12 million service contract, the first of its kind for them). But Q3 hydrogen sales were just €36 million versus €103 million a year ago, and they took a €30 million impairment after deciding not to mass-produce solid-oxide stacks in-house.

nucera supplied the 2 GW of electrolyzers at NEOM. When that plant starts making ammonia in 2027, it's the biggest real-world proof point in the industry, with nucera's name on it. Management expects one more major green hydrogen award before the end of calendar 2026. The balance sheet has €627 million of net financial assets and almost no debt, so they can wait.

Plug Power NASDAQ: PLUG

You know Plug. Everyone knows Plug. It's the stock that went from $75 to $2 and taught a generation of retail investors what "dilution" means. Accumulated deficit: $8.7 billion. Never had a profitable year.

Here's why it's still here. New CEO Jose Luis Crespo took over in March and the "Quantum Leap" restructuring is producing numbers Plug hasn't shown in years:

Q2 revenue was $178 million, operating expenses fell 50% to $62 million, net cash burn dropped 58% to $61 million, and guidance went up to 15-16% growth. Management is targeting positive EBITDA in Q4 of this year, positive operating income in Q4 2027, and actual profitability in 2028.

Now the other half: Q2 net loss was still $188 million. First-half operating cash outflow was $244 million. There's $162 million of unrestricted cash and a $2 billion equity program sitting there to fill the gap, which is a polite way of saying more shares are coming. It also still has a 30 MW UK project and the Galp refinery job in Portugal, so the electrolyzer business isn't dead, just small.

This is the highest-beta name on the list. If Q4 EBITDA turns positive, it re-rates hard. If it doesn't, you already know how this movie ends.

Big companies where green hydrogen is a bet inside a bigger business. You give up the upside of a pure-play. You get to sleep at night.

Air Products NYSE: APD

Air Products owns one-third of NEOM Green Hydrogen Company, the $8.4 billion plant in Saudi Arabia with 2.2 GW of electrolyzers, 4 GW of dedicated wind and solar, and a 30-year agreement making Air Products the sole buyer of all 1.2 million tonnes of green ammonia per year.

It's more than 90% built. First ammonia is expected in 2027, and the company warns of "a long commissioning process." In August it finalized a deal for Yara to market whatever ammonia Air Products doesn't crack back into hydrogen for Europe, which quietly reduces how much Air Products has to spend on cracking plants of its own.

Under CEO Eduardo Menezes the company has already walked away from several other clean projects, so this is the disciplined version of the bet. It's also a $60-billion-plus industrial gas company with a 40-year dividend streak, so NEOM is the swing factor on top of a boring business. If NEOM commissions cleanly, it validates the entire export model. If it slips again, the whole sector's narrative slips with it.

Linde NASDAQ: LIN

Linde is the world's largest industrial gas company and already produces, pipes and sells more hydrogen than anyone. Most of it is grey. Some of it is blue: its Beaumont, Texas plant starts producing hydrogen for ammonia in early 2027, one of the very few U.S. projects that actually attracted money this year.

The green angle is via ITM: Linde is a long-time ITM shareholder and its partner in ITM Linde Electrolysis, which builds large PEM plants for industrial customers. Linde gets to sell green hydrogen when a customer wants it, without betting its balance sheet on the color.

If you think "hydrogen wins, but not necessarily green hydrogen," this is the stock.

Bloom Energy NYSE: BE

Bloom in 2026 is an AI power stock. Its solid-oxide fuel cells run on natural gas and sit next to data centers. It booked a $2.65 billion deal with AEP, a $5 billion financing partnership with Brookfield, and the stock ran roughly 400% in a year before pulling back about 38% from its high.

The hydrogen piece is the solid-oxide electrolyzer (SOEC), which runs hot and can hit very high efficiency when you pair it with industrial waste heat. It's a legitimate technology for steel and chemicals plants that already have steam lying around.

But you're not paying for that. At a triple-digit forward P/E you're paying for gigawatts of data center power. The electrolyzer is a free option, not the thesis.

Here's the uncomfortable truth for every Western pure-play above: Chinese alkaline electrolyzers sell for $300-500 per kilowatt. Western systems go for $750-1,300. China controls about 60% of global manufacturing capacity, and in the first half of 2026 Chinese makers exported at least 321 MW, up from 18.5 MW a year earlier.

The tell: Norway's HydrogenPro shut down its own 500 MW factory in China to build on LONGi's production lines instead. When your competitor becomes your contract manufacturer, the solar playbook is repeating.

LONGi Green Energy SHA: 601012

LONGi is the world's largest solar company and its hydrogen unit has about 3.5 GW of annual electrolyzer capacity. Its "Four-in-One" 1,000 Nm³/h system is now running in Uzbekistan for ACWA Power, and it signed a 1 GW OEM agreement with HydrogenPro for Europe.

LONGi bundles cheap panels + cheap electrolyzers as one package for developers in the Middle East, Central Asia and Africa, where the cheapest power in the world lives. Hydrogen is a rounding error on LONGi's income statement today, so you're buying a solar stock with a call option. Also note: this is a mainland A-share, so access depends on your broker.

Sungrow Power SZSE: 300274

Sungrow is the inverter giant, and its Sungrow Hydrogen arm has roughly 3 GW of capacity. It shipped 160 MW of alkaline electrolyzers to ACME Group's green ammonia project in Oman this year, which is exactly the kind of export project (cheap solar, ammonia for Europe) where the real volume is happening.

Same logic as LONGi: the electrolyzer rides along with the power electronics Sungrow already sells to the same developer. It's a much smaller company than LONGi, so hydrogen matters a bit more to the story, and the same A-share access caveat applies.

Two companies that tell you more about where green hydrogen is going than most of the tickers above.

Electric Hydrogen (Private)

The first green hydrogen unicorn. Natick, Massachusetts. Electric Hydrogen raised over $750 million in equity and debt, hit a $1 billion valuation in 2023, and built a large electrolyzer factory in Devens with backing from Microsoft's climate fund and United Airlines. Its product is a standardized 100 MW PEM plant ("HYPRPlant") designed to make hydrogen at fossil-competitive cost.

The first customer-sited 100 MW plant is going up in West Texas for Infinium's e-fuels project. The company got a $46.3 million DOE manufacturing grant and is openly pushing into Europe and Latin America because it knows the U.S. window closes in 2027.

No IPO chatter, and that's the point: if the best-funded U.S. startup won't list into this market, the market isn't ready. When EH2 files, that's your green light.

Stegra (Private)

Stegra (formerly H2 Green Steel) is building Europe's first new steel mill in 50 years in Boden, northern Sweden, with a giant on-site electrolyzer (the largest in Europe) turning hydropower and wind into hydrogen that replaces coal in ironmaking. Roughly 95% less CO₂ per tonne of steel. Customers include Microsoft and thyssenkrupp Materials Services.

It nearly died. Costs ballooned, construction slowed to a crawl, and after months of bankruptcy rumors a Wallenberg-led group put up €1.4 billion in April to finish the job. The plant was about 60% complete last fall, the timeline is "under review," and management says steel comes 18-24 months after construction wraps. Total raised to date is close to $7 billion.

No IPO talk, obviously. But Stegra is the single most important demand-side project in green hydrogen. If it makes steel, every other steelmaker in Europe under CBAM has to answer the question "why not you?"

Failure mode #1: nobody signs the offtake. Every electrolyzer above is a machine waiting for a customer who'll pay a premium for years. Of the 15 winners of the second EU auction, only 6 actually signed their grant contracts. Watch that conversion rate on the nine third-round winners, whose agreements are due in Q4 2026. If it's another 40%, the "orders are back" story is hollow.

Failure mode #2: China commoditizes the hardware before Western makers reach scale. This already happened in solar, and it destroyed every Western panel maker. If EU local-content rules don't hold, Nel, ITM and nucera are competing against $300/kW. Watch whether the fourth EU auction (€500 million, end of 2026) tightens the "made in Europe" screws, and whether more Western firms quietly outsource to LONGi like HydrogenPro did.

Bonus U.S.-specific risk: DOE has asked Congress to redirect $3.5 billion of hydrogen hub money to "baseload power." If that passes, assume the American market is a 2027 construction sprint and then nothing.

Next 12-18 months, in order of importance:

NEOM commissioning (2027). First ammonia from the world's biggest green hydrogen plant. Good news re-rates Air Products, nucera, and the whole export thesis. Another delay sets the sector back years.

Q3/Q4 earnings from the pure-plays. ITM full-year on September 15. Nel Q3 on October 21. Plug Q4 (positive EBITDA or bust) early 2027. nucera's fiscal year closes September 30. These four prints tell you whether the order books are turning into revenue.

EU grant signatures in Q4 2026. Nine winners, €1.09 billion. Count how many sign.

The 45V countdown. U.S. projects must start construction by December 31, 2027. Expect a mini-boom of groundbreakings in 2027 from anyone who already has permits and electrolyzer slots booked, then a cliff. Equipment makers with U.S. inventory (Plug, Electric Hydrogen) get a one-time bump.

Stegra finishing the mill. Any confirmed completion date is a catalyst for the entire "green steel needs green hydrogen" argument.

Nel naming a CEO. Not a small thing for a company with shrinking cash.

Green hydrogen went from "everything, everywhere" to "a few real projects with cheap power and paying customers." That's a better industry to invest in. Just size your positions like everything on this list can go to zero, because for a couple of them, that's still on the table.
