The hydrogen combustion engine (H2-ICE) market is forecast to climb from $1.7 billion in 2026 to $20.8 billion by 2036, registering a rapid 28.5% CAGR. This inflection reflects a change in how heavy industry decarbonizes, with hydrogen combustion emerging as a third pathway alongside battery-electric and fuel cells.
Why it matters
Hydrogen combustion is moving from prototypes into commercial scaling, accelerated by regulatory signals that increasingly treat the technology as a compliant route to zero-emission targets. For procurement leaders, this introduces a third lane for fleet decarbonization that preserves payload and refueling speed while reducing 'range anxiety' in long-haul and off-highway duty cycles.
The details
The next decade of market expansion will be defined less by core engine layouts and more by the industrialization of hydrogen-capable fuel delivery systems, especially given hydrogen's low density and handling constraints. Investment focus has shifted toward injection, sealing, and high-pressure subsystems that determine real-world power density, efficiency, and durability.
- In 2024, Japan increased its hydrogen-related budget to JPY 20.3 billion, supporting supply chain readiness that can serve combustion applications alongside fuel cells.
- By the end of this decade, Volvo plans to make hydrogen combustion trucks commercially available.
The players
Volvo
A Swedish multinational manufacturing company that has formed a joint venture with Westport to commercialize High-Pressure Direct Injection (HPDI) systems for hydrogen combustion engines.
Weichai Power
A Chinese state-owned automotive and equipment manufacturing company that has demonstrated a 53.09% thermal efficiency milestone on a diesel engine platform, showcasing the importance of efficiency in the competitive landscape.
Cummins
An American multinational corporation that designs, manufactures, and distributes engines, filtration, and power generation products. Cummins has delivered a hydrogen internal combustion engine to Anadolu Isuzu for integration and commercial testing.
JCB
A British multinational corporation that manufactures equipment for construction, agriculture, waste handling, and demolition industries. JCB has invested £100 million into hydrogen engines, reinforcing how major equipment manufacturers view H2-ICE as a quick path to fleet-wide carbon reduction in off-highway applications.
MAN Energy Solutions
A German engineering company that is a leading provider of large-bore diesel engines and turbomachinery for marine and stationary applications. MAN Energy Solutions is among the established heavy machinery and engine leaders competing in the hydrogen combustion engine market.
What’s next
The judge in the case will decide on Tuesday whether or not to allow Walker Reed Quinn out on bail.
The takeaway
This case highlights growing concerns in the community about repeat offenders released on bail, raising questions about bail reform, public safety on SF streets, and if any special laws to govern autonomous vehicles in residential and commercial areas.
