Startup landscape: Hydrogen & e-fuels — the companies to watch and why

Global investment in hydrogen and e-fuel startups surpassed $12.4 billion in 2025, a 38% increase over 2024, yet fewer than 15% of funded ventures have reached commercial-scale production. This gap between capital deployment and operational output defines the central tension of the hydrogen startup landscape in 2026: investors must distinguish between companies building genuine technological and commercial advantages and those riding the broader policy tailwind without a credible path to cost parity. Europe remains the epicenter of this market, accounting for 52% of global electrolyzer manufacturing capacity commitments and hosting the regulatory architecture that gives hydrogen startups their clearest route to revenue.

Why It Matters

The European Union's REPowerEU plan targets 10 million tonnes of domestic green hydrogen production by 2030, backed by Hydrogen Bank auctions that awarded EUR 720 million in subsidies during the first two rounds in 2024 and 2025. Germany's H2Global mechanism has committed EUR 4.4 billion to bridge the cost gap between green hydrogen production costs and what industrial buyers will pay. The UK's Hydrogen Production Business Model (HPBM) allocated GBP 2.1 billion in contracts for difference to support electrolyzer projects through 2025. These policy commitments create a structured demand signal that de-risks early-stage hydrogen ventures in ways that other clean energy segments lack.

Simultaneously, hard-to-abate sectors face escalating decarbonization pressure. The EU Emissions Trading System (ETS) carbon price averaged EUR 68 per tonne in 2025, and the Carbon Border Adjustment Mechanism (CBAM) began its transitional phase in October 2023, with full implementation scheduled for 2026. Steel, cement, ammonia, and refining operations collectively account for roughly 22% of global CO2 emissions and have limited electrification pathways, making hydrogen and derived e-fuels essential for compliance. Aviation and maritime shipping, responsible for approximately 5% of global emissions, face the International Maritime Organization's 2027 carbon pricing mechanism and the EU's Sustainable Aviation Fuels mandate requiring 6% SAF blending by 2030.

For investors, the hydrogen startup landscape presents asymmetric return profiles. Companies that achieve commercial-scale production with electrolyzer costs below $300 per kilowatt and levelized hydrogen costs under $3 per kilogram can capture margins in a market projected to reach $642 billion by 2035 (McKinsey Hydrogen Council, 2025). Those that cannot will join the growing list of ventures that consumed hundreds of millions in capital without delivering a single tonne of merchant hydrogen.

Key Concepts

Green Hydrogen is produced through water electrolysis powered by renewable electricity. The dominant electrolyzer technologies include proton exchange membrane (PEM), alkaline, and solid oxide electrolysis cells (SOEC). Green hydrogen production costs ranged from $3.50 to $6.80 per kilogram in 2025, depending on electricity prices and electrolyzer utilization rates. The cost trajectory depends primarily on renewable electricity pricing (which accounts for 60-70% of production cost) and electrolyzer capital expenditure reductions through manufacturing scale.

E-fuels (Electrofuels) are synthetic hydrocarbons produced by combining green hydrogen with captured CO2 through Fischer-Tropsch synthesis, methanol synthesis, or direct methane production. E-fuels can substitute directly for fossil jet fuel, marine diesel, and natural gas without engine modifications, making them the primary decarbonization pathway for transport sectors where direct electrification is impractical. Current production costs range from $5 to $12 per gallon-equivalent for e-kerosene, compared to $2.50 to $3.50 for conventional jet fuel.

Electrolyzer Manufacturing Scale refers to the transition from bespoke, project-by-project fabrication to standardized, high-volume production of electrolysis systems. Industry consensus holds that achieving stack manufacturing at gigawatt-scale annual capacity is necessary to reduce electrolyzer costs from the current $500 to $1,200 per kilowatt to the $200 to $300 per kilowatt range needed for cost-competitive hydrogen. This manufacturing challenge is as critical as the underlying electrochemistry.

Hydrogen Derivatives include ammonia (NH3), methanol (CH3OH), and synthetic natural gas (SNG), each serving as a hydrogen carrier or end product for specific industrial applications. Green ammonia, produced using hydrogen from electrolysis and nitrogen from air, addresses both the fertilizer market (180 million tonnes annually) and the emerging maritime fuel market. Derivative economics are often more favorable than pure hydrogen because they solve the storage and transport cost challenges that penalize gaseous or liquid hydrogen.

What's Working

Integrated Project Developers with Offtake Agreements

The startups demonstrating the clearest path to commercial viability are those that have combined electrolyzer deployment with secured long-term offtake agreements from industrial buyers. HyCC, a Netherlands-based developer, secured a 15-year offtake contract with OCI Global for green hydrogen supply to its ammonia plant in Delfzijl, underpinning a 200 MW electrolyzer project that reached financial close in late 2025. The project benefits from Dutch SDE++ subsidy support and direct pipeline connection to the industrial cluster, eliminating transport costs. This model of co-locating production with demand and locking in revenue before construction mirrors the approach that succeeded in early solar and wind development.

Electrolyzer Manufacturing Scale-up

Manufacturers achieving genuine factory-scale production are separating from the pack. ITM Power's Bessemer Park facility in Sheffield operates at 1.5 GW annual manufacturing capacity for PEM electrolyzers, with unit costs declining 28% between 2023 and 2025 as production volumes increased. Nel Hydrogen's Heroya facility in Norway reached 500 MW annual alkaline electrolyzer capacity, with plans to scale to 4 GW. Enapter's mass-production facility in Saerbeck, Germany, applies modular anion exchange membrane (AEM) electrolysis at scale, targeting sub-$500/kW stack costs through assembly-line manufacturing techniques borrowed from the automotive industry.

E-fuel Projects Backed by Aviation Mandates

The Haru Oni pilot facility in Chile, developed by HIF Global (backed by Porsche and Siemens Energy), produced its first batches of synthetic gasoline and e-kerosene in 2023, demonstrating the full CO2-to-fuel pathway at a 12,000-liter-per-year scale. While the pilot remains far from commercial economics, the technical validation and regulatory momentum from EU SAF mandates have attracted significant follow-on investment. HIF Global's planned 550-million-liter commercial facility in Matagorda, Texas, secured offtake commitments from multiple airlines and reached final investment decision in 2025, representing the most advanced large-scale e-fuel project globally.

What's Not Working

Capital-Intensive Scale-up Without Revenue

Multiple well-funded hydrogen startups have consumed hundreds of millions in investment capital while generating minimal or zero revenue. The gap between fundraising announcements and actual hydrogen deliveries remains a systemic concern. Several prominent European ventures announced gigawatt-scale projects between 2021 and 2023 that have since been delayed, downsized, or cancelled as construction costs escalated 30-50% above initial projections and power purchase agreement prices failed to meet business case assumptions. Investors should scrutinize the ratio of capital raised to hydrogen actually delivered, not just to planned capacity.

Pure-play Electrolyzer OEMs Without Differentiation

The electrolyzer manufacturing segment has become crowded, with over 200 companies globally claiming to produce electrolysis equipment. Many lack meaningful technological differentiation or manufacturing cost advantages. Chinese manufacturers, led by LONGi Hydrogen, Peric, and Sungrow, now offer alkaline electrolyzers at $200 to $300 per kilowatt, prices that most European and North American startups cannot match even at projected scale. Startups competing primarily on PEM or alkaline technology without clear performance advantages in efficiency, durability, or system integration face severe margin pressure.

Hydrogen Transport and Storage Economics

The "last mile" challenge of delivering hydrogen to end users continues to undermine project economics. Compressing hydrogen to 350-700 bar for tube trailer transport costs $1.50 to $2.50 per kilogram, and liquefaction adds $2 to $3 per kilogram. These handling costs can double the delivered price of hydrogen compared to production cost, effectively erasing the advantage of low-cost renewable electricity. Startups that have not solved the logistics equation, either through pipeline access, on-site production, or conversion to more transportable derivatives, face structural disadvantage.

• Stress-test business cases against scenarios where natural gas prices decline or carbon prices stagnate

FAQ

Q: Which electrolyzer technology will dominate the market by 2030? A: No single technology will dominate all applications. Alkaline electrolyzers hold cost advantages for large-scale, steady-state production and currently represent roughly 60% of installed capacity. PEM electrolyzers offer faster response times and higher current densities, making them better suited for variable renewable power profiles and smaller footprints. SOEC technology achieves the highest efficiency when paired with industrial waste heat but remains at earlier commercial maturity. AEM technology promises to combine alkaline cost structures with PEM performance but has not yet been validated at large scale. Portfolio investors should maintain exposure across multiple technology pathways.

Q: What hydrogen production cost is needed for e-fuels to compete with fossil alternatives? A: For e-kerosene to reach cost parity with conventional jet fuel (approximately $2.50 to $3.50 per gallon) without subsidies, hydrogen must cost below $1.50 per kilogram, a target that no commercial project has achieved. With EU SAF mandates and carbon pricing at EUR 65 to 100 per tonne, e-kerosene becomes competitive at hydrogen costs of $2.50 to $3.00 per kilogram, which leading projects in regions with excellent renewable resources (Chile, Middle East, North Africa) expect to approach by 2028 to 2030.

Q: How should investors evaluate hydrogen startup claims about project pipelines? A: Apply a graduated discount to announced pipelines. Projects with signed engineering, procurement, and construction (EPC) contracts and confirmed financing should receive 80-100% weighting. Projects with binding offtake agreements but pending construction financing warrant 40-60% weighting. Projects with memoranda of understanding or feasibility studies should receive 5-15% weighting. The hydrogen sector has experienced significant "announcement inflation" where aggregated pipeline figures far exceed realistic deployment timelines.

Q: What role does China play in the competitive landscape for European hydrogen startups? A: Chinese manufacturers now produce alkaline electrolyzers at $200 to $300 per kilowatt, roughly 40-60% below European competitors. This pricing pressure threatens European electrolyzer OEMs unless they differentiate on efficiency, durability, system integration, or local content requirements. However, EU regulations and Hydrogen Bank subsidy conditions increasingly require European-manufactured equipment, and CBAM creates a framework for penalizing hydrogen produced with high-carbon electricity. European startups that combine competitive manufacturing with regulatory compliance advantages retain defensible market positions.

Q: Are hydrogen trucking and fueling infrastructure startups viable investments? A: Hydrogen mobility infrastructure faces a classic chicken-and-egg problem: fueling stations need vehicle fleet commitments to justify capital expenditure, and fleet operators need fueling networks to justify vehicle purchases. The most viable infrastructure plays focus on captive fleet applications (transit buses, port drayage, warehouse forklifts) where route predictability enables station utilization rates above 40%. Open-access retail hydrogen stations have struggled with utilization rates below 15%, making current unit economics challenging without sustained public subsidy.
