Hydrogen Fuel Cells in Heavy Transport: Complement or Competitor to Batteries?
#Mobility
engineering

The battery-versus-hydrogen debate has been one of the most polarizing conversations in clean transport. For passenger vehicles, the verdict is largely in — batteries win on efficiency, infrastructure maturity, and cost. But for heavy-duty transport, where payload capacity, refueling time, and range requirements push battery packs to impractical sizes, hydrogen fuel cells present a compelling and increasingly viable alternative.

At Güil Mobility Ventures, we take a mode-specific view: the question isn’t whether hydrogen or batteries will win, but where each technology delivers superior total cost of ownership and operational fit.

The Physics Argument for Hydrogen in Heavy Transport

A fully loaded Class 8 truck covering 800 kilometers per day would require a battery pack exceeding 1,000 kWh — roughly 6,000 kilograms of lithium-ion cells with current energy densities. That weight directly reduces payload capacity, which is the primary revenue driver for freight operators. A hydrogen fuel cell system delivering equivalent range weighs roughly one-third as much, and refueling takes 10–15 minutes versus hours of charging.

The energy density advantage becomes even more pronounced in maritime and aviation applications. A container ship crossing the Pacific cannot carry the battery mass required for the journey. Green hydrogen and its derivatives — ammonia for maritime, synthetic kerosene for aviation — offer energy-dense alternatives that fit existing vessel and aircraft architectures with manageable modifications.

The Cost Challenge

Hydrogen’s Achilles’ heel has always been cost. Green hydrogen — produced via electrolysis powered by renewable energy — currently costs $4–$6 per kilogram, roughly three times what’s needed to compete with diesel on a per-mile basis. The pathway to $1.50–$2.00 per kilogram requires massive scaling of electrolyzer manufacturing, cheap renewable electricity, and efficient distribution networks.

The US Inflation Reduction Act’s production tax credit of up to $3 per kilogram for clean hydrogen has dramatically improved project economics. Europe’s REPowerEU plan targets 10 million tonnes of domestic green hydrogen production by 2030. These policy signals are catalyzing investment in production capacity, but the build-out timeline is measured in years, not months.

Real-World Deployments

Despite cost headwinds, hydrogen fuel cell trucks are entering commercial service:

  • Hyundai’s XCIENT — over 80 fuel cell trucks operating in Switzerland since 2020, with expansion into Germany and the Netherlands. Hyundai’s pay-per-kilometer model sidesteps the upfront cost barrier.
  • Nikola’s HYLA — despite corporate governance turmoil, Nikola has delivered fuel cell trucks to early customers and is building a hydrogen refueling network along key US freight corridors.
  • Toyota and Hino — joint development of Class 8 fuel cell trucks for the North American market, leveraging Toyota’s decades of Mirai fuel cell experience.

In maritime, shipping giants Maersk and CMA CGM are investing in green methanol and ammonia-powered vessels, while the aviation sector is watching Airbus’s ZEROe hydrogen aircraft program with cautious optimism.

Our Perspective

We don’t invest in hydrogen versus batteries as a binary bet. We invest in the infrastructure and technology layers that enable whichever solution fits each use case. Electrolyzer manufacturers, hydrogen storage systems, and refueling network operators are positioned to capture value regardless of which OEM wins the vehicle market.

The heavy transport sector is too large and too critical to decarbonize with a single technology. Batteries will dominate short-haul and urban freight. Hydrogen will find its niche in long-haul, high-payload, and fast-turnaround applications. The smart capital is positioned across both.
