Hydrogen combustion engine market seen topping $80.9B by 2030

The Business Research Company says the hydrogen combustion engine market is on track to surpass $80.9 billion by 2030, driven by government policy, heavy-duty transport demand and new engine technologies. North America is expected to lead the market, with the U.S. emerging as the largest country market by the end of the decade.

Why it matters: - The hydrogen combustion engine market is moving from niche development toward broader commercial use in transport, industrial power and heavy-duty equipment. - The market forecast points to a major growth opportunity for engine makers, hydrogen suppliers and fleet operators as emissions rules tighten and infrastructure expands. - The segment could capture about a quarter of the commercial internal combustion engine market by 2030, making it strategically important inside a much larger machinery industry.

What happened: - The Business Research Company published its Hydrogen Combustion Engine Global Market Report 2026 – Market Size, Trends, And Forecast 2026-2035 on Oct. 27, 2026. - The report forecasts the hydrogen combustion engine market will exceed $81 billion by 2030, up from a smaller base in 2025, with a 12% compound annual growth rate through 2030. - North America is projected to lead the market, reaching $30 billion in 2030 from $17 billion in 2025. - The United States is expected to be the largest country market, growing to $26 billion in 2030 from $15 billion in 2025.

The details: - Government incentives, tax breaks, research funding and tighter emissions standards are expected to add about 2.1% annual growth to the market. - Commercial transportation and heavy-duty logistics are projected to contribute another 1.7% annual growth, driven by trucks, buses and construction equipment that need long range and fast refueling. - Hydrogen’s high auto-ignition temperature is expected to add about 1.3% annual growth by improving combustion control and safety. - Hydrogen-specific variable geometry turbochargers are emerging as a performance boost for heavy-duty applications. - In April 2025, Cummins unveiled a hydrogen internal combustion engine turbocharger for European heavy-duty highway vehicles with custom aerodynamics, diagnostic features and compliance with Euro VII standards. - Proton membrane exchange is expected to lead the technology segment in 2030 with 68% market share, or about $55 billion. - The market is also segmented by installation type into OEM and retrofit, with applications across passenger vehicles, commercial vehicles, ships and other uses. - Cummins ranked first in global hydrogen combustion engine sales in 2025 with a 2% market share. - Toyota Motor Corporation also held about 2% of the market in 2025, while Volvo Group, DEUTZ AG, JCB Home, Weichai Power, MAN Energy Solutions, Caterpillar, Mitsubishi Heavy Industries and Mazda Motor Corporation each held about 1%.

Between the lines: - The market remains fairly fragmented, with the top ten players accounting for only 11% of revenue in 2025. - Moderate barriers to entry stem from emissions rules, hydrogen safety standards, complex engineering requirements and the need for reliable performance in commercial and industrial settings. - That fragmentation suggests no single company has locked up the category yet, even as incumbents and specialized developers push to shape standards and infrastructure. - The report’s growth assumptions also signal a bigger theme: hydrogen combustion is being positioned as a bridge technology that can use much of today's engine ecosystem while lowering emissions.

What's next: - The report expects North America to keep expanding as clean-hydrogen policy, tax incentives and new fueling stations build out along heavy-duty corridors. - U.S. growth is likely to be supported by hydrogen mobility pilots, industrial backup power use, fuel-compatibility partnerships and new hydrogen-ready manufacturing and testing facilities. - The report says proton membrane exchange, phosphoric acid fuel cells and other technologies together could add more than $34 billion in value by 2030. - It also points to future growth from heavy-duty rail, long-haul freight, hybrid hydrogen-electric drivetrains, decentralized refueling and onsite hydrogen production.

The bottom line: - Hydrogen combustion engines are emerging as a fast-growing niche with outsized upside in heavy-duty transport and industrial applications, especially in North America.
