Report Overview

The Global Alkaline Fuel Cells Market size is expected to be worth around USD 4.4 Billion by 2034, from USD 0.4 Billion in 2024, growing at a CAGR of 27.1% during the forecast period from 2025 to 2034.  In 2024 North America held a dominant market position, capturing more than a 46.9% share, holding USD 0.1 Billion in revenue.

Alkaline fuel cells (AFCs) use an alkaline electrolyte and can employ non-precious catalysts. They earned their stripes in the U.S. space program and have demonstrated electrical efficiencies above 60% in space applications. A core technical constraint is CO₂ sensitivity, which can degrade performance unless the inlet gas is well-scrubbed—an engineering consideration for industrial rollouts.

The industrial backdrop is increasingly favorable as hydrogen ecosystems scale. Global hydrogen demand reached ~97 Mt in 2023 and is tracking toward ~100 Mt in 2024, sustaining investment in production, logistics, and end-use technologies that AFCs can tap. Meanwhile, fuel-cell bus fleets—proxies for hydrogen infrastructure maturity—grew more than 75% in the U.S. in 2023, while total full-size zero-emission buses reached 6,147, indicating accelerating hydrogen deployment corridors.

Policy targets are a key demand and cost lever. The EU aims to produce 10 Mt and import 10 Mt of renewable hydrogen by 2030 and initially targeted 40 GW of renewable electrolyzers—ambitions that set direction for industrial decarbonization but face execution scrutiny from auditors. The UK targets up to 10 GW of low-carbon hydrogen production capacity by 2030, with at least half electrolytic, creating a pipeline for clean hydrogen use in off-grid power and construction sites where AFC generators can replace diesel. Such goals expand bankable demand and local supply, tightening project economics for alkaline systems.

In the European Union, the REPowerEU package targets 10 Mt of domestic renewable hydrogen production and 10 Mt of imports by 2030, supported by ~40 GW of electrolyzers—an upstream supply signal for AFC adoption in industry and maritime power. India’s National Green Hydrogen Mission aims for 5 MMT per year by 2030, with analyses indicating ~100–125 GW of additional renewable capacity to meet that target; the government also anticipates ₹8 lakh crore+ in investment and significant job creation—conditions that can localize AFC manufacturing and deployment.

On the supply side, AFC OEMs are translating R&D into fieldable products. In 2024, AFC Energy reported first power from a 200 kW S+ series H-Power generator—its highest-rated unit—targeting construction and temporary power segments traditionally served by diesel. The company also disclosed a 16% reduction in hydrogen consumption for its updated 30 kW generator versus the prior model, alongside capital-cost reductions per kW—concrete steps that narrow total cost of ownership and improve competitiveness against incumbent gensets.

Emerging Trends

Alkaline fuel cells are pivoting to membrane-based designs and hybrid gensets for zero-emission temporary power

A clear trend in alkaline fuel cells (AFCs) is the move away from liquid KOH systems toward alkaline (anion) exchange membrane fuel cells (AEMFCs) and their use in hybrid battery–fuel-cell generator sets for construction sites, ports, events, and telecom backup. The membrane architecture reduces carbonate fouling risk and enables compact, modular stacks that start quickly and run quietly—essential for places that must cut diesel without sacrificing reliability.

Public-sector programs are reinforcing this shift by expanding clean-hydrogen supply and demonstration budgets, which makes membrane AFC options more bankable for rental fleets and off-grid users. Technical roadmaps from national labs prioritise durability, CO₂ tolerance, and low/PGM-free electrodes, signalling where suppliers are investing to industrialise AEMFC stacks.

What makes this practical now is the hydrogen context. The International Energy Agency (IEA) reports installed electrolysers reached ~1.4 GW by end-2023, nearly double 2022, and could approach ~5 GW by end-2024. Manufacturers also scaled to ~25 GW/yr of electrolyser output by 2023. Even if only ~4% of 2030 project announcements are at final investment decision (FID), the committed base is growing, giving developers greater confidence that hydrogen for temporary power will be available near job sites and ports. These numbers matter because hybrid battery–AEMFC gensets need predictable hydrogen to displace diesel at scale.

Policy is pushing in the same direction. In the United States, the Department of Energy’s Regional Clean Hydrogen Hubs (H2Hubs) program dedicates $7 billion to seven hubs, plus up to $1 billion in demand-side support to lock in offtake—precisely the kind of assurance rental power providers seek before switching platforms. Hubs create local fuel availability, lower delivered-hydrogen risk, and open room for membrane AFC systems that pair with batteries for silent nights and low-emission logistics.

Real-world adoption experience also helps. Japan’s long-running ENE-FARM program shows how stationary fuel-cell ecosystems scale when utilities and service networks mature. More than 450,000 residential fuel-cell units were in use by September 2022, and a 2024 manufacturer tally counted ~503,000 units nationwide (FY2024.3). While most are PEM systems, the installation, maintenance, and gas-supply know-how lowers friction for other fuel-cell formats—AEMFCs included—especially in distributed power and backup roles where quiet operation and high efficiency are valued.

Drivers

Accelerating Clean Hydrogen Supply Chain and Infrastructure

When hydrogen is produced from fossil fuels, it currently causes around 830 million tonnes of CO₂ emissions annually, with only about 130 million tonnes captured. This high-carbon figure highlights the urgent need for low-carbon hydrogen production to align with clean-energy goals. In India, for example, the government’s “Green Hydrogen” initiative notes that hydrogen produced by electrolysis is now ≈60% less expensive than in 2010, thanks to falling electrolyser costs and increasing renewables supply. As hydrogen becomes cleaner and cheaper, fuel-cell systems that rely on it (including AFCs) become far more practical and cost-effective.

For AFCs specifically, the low-temperature operation (<100 °C) and relatively mature chemistry mean they can effectively make use of hydrogen from renewable-electrolysis sources, which are becoming more prevalent. With clean hydrogen production increasing, the “plug-and-play” nature of AFCs becomes more attractive in non-mobility sectors where hydrogen purity and CO₂-challenge issues can be managed more easily than in high-CO₂ environments. This ties directly into the hydrogen supply-chain growth: as more hydrogen is produced and distributed, more applications become viable, creating a virtuous cycle.

On a practical level, the Indian government’s “Green Hydrogen Policy” envisages a domestic electrolyser market of around 20 GW by 2030 in one scenario, with broader demand to reach 226 GW by 2050. While these are not AFC-specific numbers, they indicate the scale of hydrogen-growth which underpins all fuel-cell technologies. For AFCs, this means that end-users—such as small manufacturing units, remote utilities, and construction-site power providers—can increasingly count on hydrogen availability and steady pricing over time.

In more human terms, imagine a rural telecom tower now powered 24/7 by a fuel-cell system rather than a noisy diesel generator: the hum of combustion goes away; the smell of exhaust disappears; the operators worry less about fuel-truck logistics or price swings. This becomes feasible only when hydrogen supply is reliable and affordable. That shift—from fuel-logistics worries to seamless hydrogen-feed power—is made possible precisely by the growing hydrogen infrastructure and policy support.

Restraints

CO₂ Sensitivity and Hydrogen/Air Purity Requirements

A major brake on wider alkaline fuel cell (AFC) adoption is their strong sensitivity to carbon dioxide (CO₂), which drives costly gas-clean-up and operating constraints. In alkaline electrolytes (e.g., KOH), CO₂ reacts to form carbonates (K₂CO₃), lowering ionic conductivity and slowing electrode kinetics—effects directly linked to power loss. Laboratory studies show normalized power density drops as K₂CO₃ builds up in flowing-electrolyte AFCs, quantifying how carbonate formation degrades stack performance over time.

The problem is made harder by today’s air: atmospheric CO₂ is no longer a minor impurity. NOAA reports the annual average CO₂ concentration in 2024 at ~424.6 ppm, with monthly values around 423 ppm—levels high enough that “air-breathing” AFCs must scrub CO₂ or switch to oxygen, adding equipment, maintenance, and energy penalties.

These chemistry and quality realities cascade into system design. AFCs frequently need CO₂-free oxidant to avoid rapid electrolyte carbonation; delivering bottled oxygen or installing air-scrubbers raises capex and operating burden versus technologies that can tolerate air. DOE/NETL references describe how conversion of KOH to K₂CO₃ impairs anode reaction rates and increases ohmic losses, a fundamental mechanism behind performance fade when AFCs face CO₂ ingress.

Hydrogen supply uncertainty compounds the restraint. The IEA notes installed water-electrolyser capacity reached ~1.4 GW by end-2023 and could hit ~5 GW by end-2024, but only ~4% of announced projects to 2030 are at final investment decision (FID) or under construction—a gap that keeps low-carbon hydrogen volumes tight and prices volatile in many regions. For AFC operators who also need higher-purity hydrogen, this supply immaturity raises delivered-fuel costs and risk.

Policy support is growing but uneven, which matters for purity infrastructure. The IEA’s 2024/2025 tracking shows governments revising hydrogen ambitions and timelines as projects stall; outlooks for low-emissions hydrogen in 2030 were cut by nearly 25% versus prior expectations, highlighting execution headwinds in permitting, financing, and supply chains. Where hubs, pipelines, and quality standards are not yet in place, AFC deployments face longer lead times or must resort to localized gas processing to meet CO₂ specs.

Opportunity

Zero-emission temporary & off-grid power (construction, ports, telecom)

A major growth opening for alkaline fuel cells (AFCs) is replacing diesel generators in temporary and off-grid power—construction sites, port berths, outdoor events, and telecom towers. These locations need quiet, reliable power and face tightening emissions rules. Europe’s Stage V standards for non-road mobile machinery (NRMM) are among the toughest worldwide, pushing contractors to cleaner options; AFCs, running on clean hydrogen, can meet power needs without onsite exhaust.

Telecom is a vivid example. India’s sector has long relied on diesel sets for thousands of towers. A TRAI-referenced analysis estimates ~8,760 litres of diesel per tower per year (assuming 8 hours/day operation) and ~10 million tonnes of CO₂ annually from tower diesel use—costly, noisy, and polluting loads that AFCs can displace with clean hydrogen where grid power is weak. The shift improves local air quality and reduces fuel-logistics risks for operators.

Ports are another near-term beachhead. While ships at berth increasingly adopt shore-power, many terminals still run diesel for yard equipment and temporary power. The European Environment Agency reports maritime transport contributed ~24% of EU NOₓ and ~24% of SOₓ emissions in 2018, underscoring the air-quality gains from displacing diesel with fuel-cells in port operations and events near harbours. As the IMO’s 2023 GHG Strategy pushes toward net-zero for international shipping “by or around 2050,” zero-emission ground power will be in higher demand—AFCs fit well for quiet, low-temperature operation.

The opportunity strengthens as clean-hydrogen supply scales. The IEA notes installed electrolyser capacity reached ~1.4 GW at end-2023, nearly double 2022, with manufacturing capacity at ~25 GW/yr by end-2023 and rising—expanding access to low-emissions hydrogen that pairs well with AFCs for stationary/portable generators. Announced projects with FID now stand at ~20 GW of electrolysers globally, a tangible base for regional fuel availability that can feed construction and port micro-hubs.
