MARKET RESTRAINTS

Increase in Complexity of Propulsion System Compared to Conventional System will Hamper Market

The recent trend to design more efficient and versatile ships has led to a growing variety of hybrid propulsion and power supply architectures. Intelligent control strategies are required to improve performance in these architectures. Various types of ships, such as offshore vessels, naval ships, and container ships, have to perform different operations, such as transit and critical dynamic positioning, which makes it complex for the propulsion system. The varying operating profiles make it difficult to optimize power and propulsion plants for specific operating points during the vessel design stage, as has been traditionally done.

Furthermore, in marine hybrid electric propulsion systems, the electric drive system is usually controlled by a Power Management System (PMS), which optimizes load distribution. This is important because power supplies are connected to the same distribution grid, and improper power supply and demand can lead to a shutdown of the electrical system. However, developing an optimized PMS to achieve different operational load profiles is challenging as it requires sensor detection, such as fuel consumption, power output, and engine speed, which is typically not readily available. Additionally, a control strategy for the electrical network is required for the maintenance of voltage and frequency stabilization, which creates more complexities than the conventional system.

MARKET CHALLENGES

Intricate Nature of Systems and High Cost Hinders its Widespread Adoption Stifling Market Growth

Hybrid propulsion systems entail considerable initial costs compared to conventional mechanical systems. This includes expenses associated with onboard generation, distribution networks, specialized motors, and controllers. The elevated cost of these systems might discourage smaller operators or those with constrained budgets from embracing the technology. Additionally, hybrid systems require specialized maintenance and technical support, which might not be easily accessible in every port or region.

The intricate nature of these systems require experienced individuals for oversight, maintenance, and enhancements, which increases operational expenses. Incorporating lithium-ion batteries in hybrid systems presents hazards like thermal runaway, potentially leading to fires or explosions if the batteries are compromised or mismanaged. It is essential to guarantee correct installation, efficient cooling systems, and compliance with safety regulations, though this can be difficult.

Although hybrid systems help lower emissions, they continue to encounter obstacles in attaining full energy autonomy because they often depend on fossil fuels for backup power. The immediate torque generated by electric motors may lead to mechanical strain on shafts and other parts if they are not engineered to withstand such forces. There is an absence of standardized regulations specifically designed for hybrid propulsion systems in the industry. While stricter emission regulations are being developed, there is a need for better alignment with the capabilities of hybrid technology.

By operation type, the market is classified into parallel hybrid propulsion system and serial hybrid propulsion system.

Parallel hybrid propulsion systems dominated the global market in 2024 owing to their operational flexibility, relatively straightforward integration, and suitability for a broad range of vessel types and duty cycles. This configuration allows the vessel's propeller shaft to be driven directly by either the Internal Combustion Engine (ICE), the electric motor, or both simultaneously. This flexibility is particularly advantageous for vessels requiring significant power bursts or variable speeds, such as Offshore Support Vessels (OSVs), ferries, tugboats, and certain yachts. The mechanical coupling is less complex than serial systems for retrofits. It often leverages existing drivetrain components, making it a cost-effective first step toward hybridization for many shipowners seeking fuel savings and emissions compliance without a complete redesign.

For instance, in May 2023, MAN Energy Solutions supplied its new 49/60DF dual-fuel engines integrated into parallel hybrid systems for newbuild ferries and OSVs, emphasizing fuel flexibility alongside hybridization. Similarly, companies such as Schottel (in October 2023) and Wärtsilä (March 2024) enhanced their parallel hybrid solutions, focusing on control systems for seamless mode switching and optimizing energy flow, further solidifying their appeal for diverse maritime applications seeking immediate operational benefits.

Serial hybrid propulsion systems are projected to depict the fastest-growth, driven by the increasing demand for pure electric operation, optimal efficiency in variable load profiles, and alignment with future zero-emission goals. This architecture excels in applications where vessels operate frequently at low speeds or require extended periods of zero-emission operation, such as harbor tugs, short-sea shipping vessels, research vessels, and superyachts. Furthermore, serial systems offer superior scalability for battery capacity, enabling longer zero-emission endurance and paving the way for eventual transition to full electrification as battery technology advances and charging infrastructure expands.

For instance, in January 2024, Damen Shipyards Group has launched multiple Serial Hybrid tugs (like the ASD Tug 2813 Hybrid) and ferries, emphasizing their capability for silent, emission-free operation in ports. Major engine manufacturers such as Rolls-Royce (mtu) (in February 2024) and Caterpillar (MaK) (in January 2024) heavily invested in gensets specifically designed for serial hybrid applications, focusing on transient response and optimized efficiency. The push for "cold ironing" and "green port" initiatives, coupled with tightening emissions regulations (especially in Emission Control Areas - ECAs), directly fuels the adoption of serial hybrids capable of extended battery-only operation, positioning this segment for accelerated growth as the industry moves toward decarbonization.
