Gas engines market seen topping $7 billion by 2030

The global gas engines market is projected to surpass $7 billion by 2030, driven by cleaner power demand, tighter emissions rules and investment in distributed energy. Asia-Pacific is expected to lead regional growth, while the United States remains the largest country market.

Why it matters: - The gas engines market is growing as utilities and industrial operators look for cleaner, flexible power options that can support distributed generation and backup power. - The market’s long-term rise also reflects broader energy shifts toward lower-emission fuels, grid resilience and decentralized power systems. - The segment is expected to gain share even within a much larger machinery market, showing how targeted energy equipment niches can scale.

What happened: - The Business Research Company released its Gas Engines Global Market Report 2026, covering market size, trends and forecasts through 2035. - The report says the gas engines market is projected to surpass $7 billion by 2030. - The market is forecast to grow at a 6% compound annual growth rate through 2030. - Asia-Pacific is projected to be the largest regional market in 2030 at $2.8 billion, up from $1.9 billion in 2025. - The United States is expected to be the largest country market in 2030 at $1.6 billion, up from $1.3 billion in 2025.

The details: - Gas engines represent about 1% of the broader Engine, Turbine, and Power Transmission Equipment market, which is forecast to reach about $880 billion by 2030. - Gas engines account for nearly 0.1% of the wider Machinery industry, forecast at $5.28 trillion by 2030. - Asia-Pacific growth is being driven by natural gas pipelines, LNG infrastructure, industrialization, electricity demand, CHP investment and emission-reducing policies. - The U.S. market is supported by shale gas production, replacement of older diesel generators, backup power demand, utility modernization and use in data centers and healthcare. - Three major growth drivers are expected to add to market expansion through 2030: power generation and mechanical drive use, tighter environmental regulation and government-backed power infrastructure spending. - Power generation and mechanical drive applications are expected to contribute about 1.5% annual growth. - Environmental regulation is expected to contribute about 1.4% annual growth. - Government infrastructure initiatives are expected to contribute about 1.3% annual growth. - Natural gas, special gas and other fuels are projected to add more than $1.5 billion in combined market value by 2030. - Natural gas alone is expected to add $1 billion between 2025 and 2030. - Special gas is expected to add $0.4 billion, and other fuels $0.1 billion over the same period. - Natural gas engines are expected to remain the largest fuel segment in 2030 with about 66% market share, or roughly $5 billion in value. - The market is segmented by power output into 1-2 MW, 2-5 MW, 5-15 MW and above 15 MW bands. - The market also spans power generation, mechanical drive, cogeneration and other applications. - End users include utilities, marine industries, oil and gas, manufacturing and other sectors.

Between the lines: - The market remains moderately concentrated, with the top 10 companies generating 38% of revenue in 2025. - Wärtsilä Oyj Abp held the largest share in 2025 at 12%, followed by Caterpillar at 8%, Cummins at 4% and INNIO Jenbacher at 3%. - Other named players with 1% to 2% shares include MTU, Mitsubishi Heavy Industries, Everllence, Kawasaki Heavy Industries, Hyundai Heavy Industries and Yanmar. - The concentration suggests that technical complexity, emissions compliance and precision engineering continue to favor established suppliers. - Modular gas engine power plants are emerging as a key product trend because they offer scalability, faster deployment and more grid flexibility. - Rolls-Royce Power Systems introduced modular gas engine plants in February 2026 with scalable capacity from 5 MW to several hundred megawatts. - The modular systems are designed to improve grid stability and help balance renewable energy variability.

What's next: - Companies are expected to keep investing in higher-efficiency engine designs, lower-emission technologies and digital monitoring systems. - Growth is likely to continue in distributed power, microgrids, hybrid systems and low-carbon stationary power generation. - The market’s leaders are expected to defend share through product development, partnerships and geographic expansion. - The report also points to continued adoption in industrial, commercial, utility and critical infrastructure settings such as data centers and healthcare.

The bottom line: - Gas engines are moving from a niche power solution to a steady growth market tied to energy transition, grid resilience and cleaner distributed generation.
