Internal combustion engines hold 55% share in 2024 due to wide supply and lower price. These engines use natural gas and biofuel to cut emissions across transport fleets. Hybrid engines grow fast as automakers pair motors with improved batteries. Electric engines expand in light duty fleets and city travel. Fuel cell engines gain use in heavy duty roles for long range. OEMs upgrade power output and service reach for each type. Supportive policy and fleet renewal plans drive hybrid demand, yet internal combustion engines stay in lead due to base volume and retrofit options.
For instance, MAN natural gas engines reached 228 kW output with Euro 6 compliance in logistics fleets.
By Application
Automotive holds 61% share in 2024, driven by strong fleet change in road transport. Trucks, buses, and passenger cars shift toward clean engines backed by rules and cost targets. Marine use grows with LNG engines for cargo ships. Aerospace sees early use of hydrogen and hybrid test units. Industrial machinery adopts biofuel and gas engines to cut fuel spend and emissions. Carmakers expand model lines and engine supply across regions to meet fleet goals. Strong freight demand and urban rules keep the automotive segment in lead through the forecast period.
Key Growth Drivers
Rising Emission Regulations and Decarbonization Goals
Governments push lower carbon output through strict emission rules and fleet targets. These measures guide engine makers toward cleaner fuels, hybrid units, and electric power. Road transport, marine, and industrial fleets upgrade engines to meet air quality norms. Public agencies support these shifts through tax credits and grants. Large firms invest in LNG, biofuel, and hydrogen engines to meet net-zero plans. This driver boosts long-term demand as cleaner engines replace older units and help users cut lifetime running cost and emissions.
For instance, Cummins certified an engine platform that achieved 0.02 g NOx per brake horsepower-hour under CARB HD standards.
Shift Toward Cost-Effective and Clean Fuel Choices
Users adopt gas and biofuel engines to lower fuel spend and reduce carbon output. Gas engines cut fuel cost per mile and offer stable supply. Biofuel blends help owners decarbonize without major fleet change. Hybrid and electric power reduce idling loss and improve energy use. Growing fuel access, fast fill stations, and local supply support scale. This driver supports steady growth across trucking, buses, and industrial use as buyers aim for total cost gains.
For instance, Scania engines ran B100 biofuel at 360 kW rated power in logistics fleets. Hybrid and electric power reduce idling loss and improve energy use.
Advances in Engine Efficiency and Power Density
Engine makers improve thermal efficiency, torque control, and heat loss. New parts, sensors, and software raise power density and extend run time. Hybrid and fuel cell platforms expand range and load capacity. These gains help clean engines match or exceed diesel roles in heavy duty use. Lower service needs and higher uptime attract fleet owners. Strong R&D and OEM partnerships support faster launch cycles and wider product lines. This driver builds user trust and speeds adoption.
Key Trends and Opportunities
Scale-Up of Hydrogen and Fuel Cell Systems
Hydrogen moves into heavy trucks, rail, and marine roles. Users seek long range and fast fill, which support fuel cell use. Growth in green hydrogen plants and storage hubs improves supply. Engine and stack makers form deals to cut cost and improve load output. Public and private fleets test early units under real duty cycles. This trend opens strong revenue paths as hydrogen engines move from pilot to scale.
For instance, Hyundai XCIENT fuel cell trucks logged 120 kW stack power and 400 km range in fleet runs.
Growth of Connected and Smart Powertrains
Digital control units and remote checks improve uptime, range use, and service plans. Smart powertrains adjust load and fuel use to match drive needs. Telematics and data tools cut idle time and support predictive service. These gains raise fleet value and shorten payback time. The trend creates paths for service revenue, software updates, and long-term user ties. Makers of hybrid, electric, and gas engines use digital tools to stand out.
For instance, Volvo connected diagnostics reduced unplanned stops by 24 events per 100 trucks each year.
Key Challenges
Fuel Supply and Infrastructure Gaps
Access to gas, hydrogen, and fast charging shapes market pace. Sparse station networks slow fleet change and raise routing limits. Marine and heavy truck roles need wide coverage and high capacity sites. Storage cost and safety rules add delay. These gaps force users to keep mixed fleets and limit scale. Growth needs broad action from fuel firms, grid players, and public bodies.
Higher Upfront Cost and Payback Concerns
Clean engines and hybrid units cost more than diesel peers. Users weigh long-term fuel and service gains against short-term spend. Payback varies by duty cycle, fuel price, and route. Small fleets face tight budgets and risk barriers. Makers must cut system cost and offer service plans and finance tools. Clear total cost data and proven uptime help ease these concerns and support wider use.
