Introduction
Clean-energy equities — covering solar, electric vehicles (EV), and hydrogen — have surged to the forefront of 2025’s investment conversation. Declining costs of renewables, increasing demand for clean power, and supportive policy frameworks have driven substantial capital toward green technologies. For many investors, these equities offer a rare confluence: the possibility of strong financial returns and the ability to back a low-carbon future.
While solar remains the backbone of capacity expansion in the U.S., and EV stocks ride the wave of transportation electrification and infrastructure rollout, hydrogen is increasingly viewed as the next frontier. As sectors like heavy transport, industry, energy storage, and carbon-intensive manufacturing seek low-carbon alternatives, hydrogen — especially green hydrogen — promises a unique value proposition and diversification beyond solar panels and batteries.
This blog dives deep into the key market drivers, the leading public hydrogen equities in the U.S., the relative appeal compared to solar and EV plays, and the risks investors should weigh before committing capital.
Why Hydrogen — and Why Now? Market Overview & Growth Drivers
U.S. Hydrogen Market — Scope & Evolution
The U.S. hydrogen market is already substantial: as of 2025, the country accounts for over half of the world’s fuel-cell vehicles, more than 25,000 fuel-cell material-handling vehicles, and over 550 MW of large-scale fuel-cell–based power projects either installed or planned. Nasdaq+2nai500.com+2
In 2023, the U.S. exported around US$2.15 billion in hydrogen, making it the top hydrogen exporter globally. usfinanceinsider.com+1
On the infrastructure side, the domestic market for hydrogen electrolyzers (the devices that produce green hydrogen via water and electricity) is expanding rapidly: a recent estimate pegs U.S. 2025 market size in the hundreds of millions, with strong growth expected through 2034. Industry Research+1
Policy, Technology & Macro Drivers
Green-hydrogen viability is improving thanks to lower renewable-electricity costs, improved electrolyzer efficiency, and growing interest in decarbonization by heavy industries and transport sectors. arXiv+2usfinanceinsider.com+2
The global green-hydrogen market is forecast to reach USD 413.20 billion by 2035, reflecting broad optimism around hydrogen’s role in the clean-energy transition. GlobeNewswire
U.S. policy — formerly a major tailwind via production tax credits, infrastructure funding, and incentives — remains under flux, but many large firms and firms with diversified hydrogen capabilities continue investing, often pivoting toward “blue” hydrogen (natural gas + carbon capture) where economics still favor near-term returns. usfinanceinsider.com+2nai500.com+2
On the supply side, demand from heavy-duty transport, industrial users, and energy-storage applications is slowly rising — sectors where battery electrification is less feasible or cost-efficient.
Why Hydrogen Matters for Investors
Hydrogen offers diversification beyond solar and battery-based clean energy plays. It targets different market segments (heavy transport, industrial energy, long-duration storage) that are unlikely to be disrupted purely by solar + batteries.
As hydrogen adoption grows, early investors might benefit from outsized long-term gains: a hydrogen economy is still nascent, and many companies are relatively small or mid-cap — implying higher growth potential (but also higher risk).
For clean-energy portfolios, adding a hydrogen slice can balance exposure: solar for stable growth; EV/battery for transport electrification; hydrogen for industrial-scale decarbonization and future-proofing.
Given this backdrop, let’s examine some of the top hydrogen equities (and ETFs) in the U.S. that investors are watching in 2025.
Leading U.S. Hydrogen Stocks & ETFs Worth Watching
Here’s a look at some of the most significant public companies and ETFs giving exposure to hydrogen — along with what sets them apart, and their risks.
🔹 Stock Picks
| Company | What They Do / Why They Stand Out | Key Considerations / Risk |
|---|---|---|
| Linde (NYSE: LIN) | A global industrial-gases giant with deep involvement across the hydrogen value chain — production, processing, distribution, storage. Via its joint venture (ITM Linde Electrolysis), it’s among the few with established green hydrogen electrolyzer capabilities. | Because of regulatory uncertainty, ~90% of its U.S. hydrogen projects are now focused on blue hydrogen (natural gas + carbon capture) to keep costs down. |
| Cummins Inc. (NYSE: CMI) | Under its “Accelera” brand, Cummins offers hydrogen fuel cells, electrolyzers, and zero-carbon powertrain systems — aiming to serve both industrial and mobility markets. | As with many hydrogen plays, profitability depends on broader scale-up, corporate offtake, and supportive infrastructure. |
| Air Products & Chemicals (NYSE: APD) | Provides hydrogen infrastructure and distribution; globally active in hydrogen supply and among the largest hydrogen network operators. nai500.com+1 | Mixed exposure — some operations tied to traditional industrial gases; hydrogen remains one of multiple business lines. |
🔹 High-Growth / Fuel-Cell / Electrolyzer-Focused Companies
Plug Power (NASDAQ: PLUG) — A well-known hydrogen-fuel-cell player in the U.S., Plug Power builds end-to-end hydrogen solutions (production, storage, distribution, fuel-cell systems).
Ballard Power Systems (NASDAQ: BLDP) — Focused on fuel-cell solutions especially for commercial transport (buses, trucks, trains), and heavy-duty applications where batteries may not suffice.
Bloom Energy (NYSE: BE) — Leveraging fuel-cell and hydrogen infrastructure technologies, often highlighted in hydrogen ETFs.
These companies represent a mix of “infrastructure heavyweights” (Linde, Air Products, Cummins) and “high-volatility, high-upside” tech players (Plug Power, Ballard, Bloom).
🔹 Hydrogen ETF Option
For investors wanting breadth rather than single-stock risk:
Global X Hydrogen ETF (NASDAQ: HYDR) — This ETF aims to track a global hydrogen index, giving exposure to 20–30 companies involved in hydrogen production, fuel-cell manufacturing, and related technologies. As of late 2025, its holdings include companies like Bloom Energy, Plug Power, Ballard, Doosan Fuel Cell, and Ceres Power.
Because of sector volatility, and since hydrogen companies are often in early-stage growth phases, HYDR (or similar hydrogen-heavy ETFs) can offer a smoother ride for investors unable to pick individual winners.
Hydrogen vs Solar & EV — Diversification and Comparative Potential
Hydrogen is often talked about as “the missing piece” in clean energy portfolios — complementing, rather than competing with, solar or EV plays. Here’s how:
Sector Focus Differences: Solar equities are tied to capacity expansion, manufacturing, module pricing, supply-chain dynamics; EV equities revolve around vehicle demand, battery supply, charging infrastructure, and consumer adoption. In contrast, hydrogen equities are tied to industrial usage, large-scale fuel-cell deployment, long-duration energy storage, and decarbonization of heavy-duty transport/industry — areas not addressed as well by solar or batteries alone.
Risk & Return Profiles: Solar and EV stocks — especially mature players — may offer comparatively lower volatility. Hydrogen firms, particularly those focused on electrolyzers or fuel cells, may be more volatile but also have higher long-term growth potential if hydrogen adoption scales.
Complementary Demand Drivers: As renewable electricity (from solar and wind) becomes cheaper, green-hydrogen production becomes more economically viable, potentially boosting both sectors simultaneously. Meanwhile, industrial demand, heavy-transport electrification, and carbon-intensive manufacturing decarbonization — where hydrogen shines — are largely orthogonal to solar and EV demand dynamics.
In short: a portfolio blending solar, EV, and hydrogen equities could strike a balance between short-to-mid-term stability (from solar/EV) and long-term upside (from hydrogen).
Risks & Headwinds: What Could Go Wrong
While hydrogen presents an alluring growth story, there are several risks investors must carefully consider.
Policy Uncertainty & Incentive Changes
Hydrogen’s economics — especially for green hydrogen — have relied heavily on subsidies, tax credits, and regulatory support. For example, recent forecasts for U.S. green hydrogen production were downgraded by analysts after changes to hydrogen incentives under U.S. federal policy.
Many proposed projects are now re-evaluating timelines or switching to blue hydrogen (natural gas + carbon capture) because it remains more cost-efficient under current regulations.
High Production Costs (Especially for Green Hydrogen)
According to a recent techno-economic analysis, green hydrogen still costs more per kilogram than conventional hydrogen (gray or blue), unless renewable power becomes very cheap (e.g., <$20–30/MWh) and electrolyzer efficiencies improve.
Until green hydrogen achieves cost parity, adoption may be limited — especially in cost-sensitive industries.
Infrastructure & Scalability Challenges
Hydrogen requires dedicated production, storage, transport, and refueling infrastructure — pipelines, electrolysis facilities, fuel-cell manufacturing. Building this at scale is capital-intensive and will take time.
Compared with solar (where manufacturing and installation are relatively modular and scalable) or battery-electric for cars (which piggybacks on existing charging + power infrastructure), hydrogen’s infrastructure build-out is more complex and slower.
Market Competition & Technology Risk
In sectors like transport, hydrogen competes with battery-electric solutions (for light vehicles) and with newer battery technologies, so it may struggle to win market share unless it delivers clear cost or performance advantages.
For industrial use, hydrogen must demonstrate long-term reliability, cost-effectiveness, and regulatory compliance — any failure or delay could hurt investor confidence.
Given these risks, many experts advise diversifying: instead of going “all in” on hydrogen, hold a mix of hydrogen + solar + EV (or broader clean-energy) equities.
Sample Portfolio Allocation: Clean-Energy Mix for 2026
Here’s a sample allocation model for an investor looking to balance growth potential with risk mitigation. This is just illustrative — actual allocation should reflect individual risk tolerance, time horizon, and investing goals.
| Asset Class / Focus | Allocation % | Rationale |
|---|---|---|
| Established Solar / Renewable Energy Stocks or Solar-focused ETFs | 30–40% | Solar has shown consistent growth, stable demand, and benefits from long-term renewables build-out; lower volatility relative to hydrogen. |
| EV and Battery / EV-Infrastructure Stocks & ETFs | 25–35% | Reflects rising consumer adoption of EVs, growth in charging infrastructure, supportive regulation and incentives for electrification. |
| Hydrogen-focused Stocks & Hydrogen ETF (e.g., HYDR) | 10–20% | Offers high-upside exposure to hydrogen economy’s growth; diversification into heavy-duty transport, storage, industry applications that solar and batteries alone can’t address. |
| Mixed Clean-Energy / Diversified ESG / Green Energy ETFs | 5–15% | Helps smooth volatility, provide broad exposure across clean-tech sectors, and manage company-specific risk. |
Note: This allocation leans moderately aggressive, with a decent hydrogen “slice” but still balanced across solar, EV, and broader clean energy. Conservative investors may choose to reduce hydrogen allocation; aggressive investors may tilt more heavily toward hydrogen or high-growth EV / battery firms.
Why 2025–2030 Could Be a Critical Window for Hydrogen
Declining Costs + Scale-up of Electrolyzer Market
The global electrolyzer market — the backbone of green hydrogen — is forecast to grow at ~30% CAGR between 2025 and 2034. Industry Research+1
As more electrolyzers are deployed and economies of scale kick in, production costs per kg of hydrogen should decline. Combined with cheaper renewable electricity, this could make green hydrogen competitive with fossil-based alternatives within the next 5–10 years.
Growing Demand from Hard-to-Decarbonize Sectors
Industries and heavy-duty transport segments (shipping, trucking, industrial heating, steel production, chemicals) are harder to electrify via batteries, making hydrogen a strong candidate for decarbonization.
As companies and regulators increasingly push for net-zero targets, hydrogen may become a preferred solution — creating large demand pools.
Potential for Policy Revival / New Incentives
While recent U.S. policy shifts have created headwinds, change in political leadership or renewed climate action could reinvigorate incentives, infrastructure funding, and clean-energy tax credits — benefiting hydrogen firms.
International demand (exports) and partnerships — hydrogen trading, cross-border supply chains, global green-hydrogen projects — may also boost profitability for U.S. producers and technology firms.
Top Hydrogen Stocks & ETF: Quick Reference (2025)
To help illustrate what a hydrogen-focused slice of a portfolio might look like, here are three leading hydrogen stocks (with recent market data) and one hydrogen-focused ETF:
Plug Power (PLUG): A pioneer in hydrogen fuel-cell and electrolyzer systems — building infrastructure and pushing hydrogen adoption for mobility, industrial, and energy storage applications.
Ballard Power Systems (BLDP): Focused on hydrogen fuel-cell solutions for transport (trucks, buses, trains) and heavy-duty applications.
Bloom Energy (BE): Offers hydrogen fuel-cell and related clean-energy technologies; often a major holding in hydrogen ETFs.
Global X Hydrogen ETF (HYDR): Provides broad exposure to ~25 hydrogen-related companies — a way to invest in hydrogen without single-stock risk.
How to Evaluate & Monitor Hydrogen Investments — What Investors Should Watch
If you decide to include hydrogen equities in your portfolio, here are some key metrics and indicators to monitor over time:
Electrolyzer capacity expansion: Growth in new electrolyzer installations (in U.S. and globally) will signal scaling of green-hydrogen production.
New offtake agreements & industrial / transport adoptions: Hydrogen demand typically ramps via long-term contracts with industry, transportation, or utility customers — such deals often act as catalysts for stock performance.
Policy and regulatory developments: Tax credits, infrastructure funding, carbon-pricing regimes, clean-energy grants — all can significantly impact hydrogen economics.
Cost per kilogram of hydrogen produced: Watch for trends in renewable-electricity pricing and electrolyzer efficiency — which directly influence hydrogen’s competitiveness versus fossil fuels.
Competition from battery electrification or alternative clean technologies: Hydrogen must carve out niches where batteries or other solutions aren’t viable (heavy industry, long-haul transport, large-scale energy storage) — but changes in battery tech can encroach on hydrogen territory.
Additionally, for investors less comfortable with company-specific risk, hydrogen ETFs (like HYDR) or broad clean-energy ETFs can help smooth volatility while preserving upside potential.
Conclusion
The clean-energy transition is no longer a future hope — it’s unfolding in real time. While solar and EV equities have already captured substantial investor interest, hydrogen is emerging as the next frontier, offering exposure to long-duration energy storage, industrial decarbonization, heavy-duty transport, and large-scale clean energy infrastructure.
Yes — hydrogen equities come with higher risk. Production costs are still elevated, infrastructure remains a limiting factor, and policy headwinds may pose near-term volatility. But the upside, particularly over the next 5–10 years, is significant: as electrolyzer costs fall, renewable energy becomes cheaper, and demand from industries and heavy-duty transport grows, hydrogen could move from the fringes to the backbone of the clean-energy economy.
For U.S. investors today, a balanced clean-energy portfolio might combine:
Solar (for stability)
EV / battery / charging infrastructure (for consumer electrification)
Hydrogen (for industrial-scale decarbonization and long-term upside)
Starting with a modest hydrogen allocation (e.g. 10–20%) — via stocks or ETFs — may offer the best risk-adjusted approach. Over time, as the hydrogen economy matures, that allocation can be increased.
