How can marine players achieve sustainability targets while making the right technology and infrastructure decisions?
The marine industry is facing increasing pressure to reduce emissions and improve overall sustainability across vessels and operations. This goes beyond propulsion systems and includes lifecycle emissions, energy efficiency, operational impact, and compliance with evolving environmental regulations. At the same time, new requirements are emerging not only for shipbuilders and OEMs, but also for infrastructure operators such as ports including the equipment being used within harbor areas.
A key challenge remains the uncertainty around future propulsion technologies and energy carriers. No single solution – whether methanol, ammonia, hydrogen, electricity, or synthetic fuels – has emerged as a clear standard. Each option presents trade-offs in cost, infrastructure requirements, safety, technology readiness, and suitability for specific vessel applications and operating profiles.
Long asset lifecycles and development timelines further increase complexity. Decisions on fuel pathways, powertrain concepts, and infrastructure investments must be taken today, while their impact extends into 2030 – 2050 and beyond. Wrong decisions can lead to stranded investments, regulatory non-compliance, or unnecessary cost exposure due to over-compliance.
As a result, marine players must make coordinated decisions across vessels, powertrain technologies, and infrastructure – without clear long-term standards or stable boundary conditions.

Case samples
How does FEV Consulting apply marine expertise in real-world projects?
FEV Consulting supports marine stakeholders across strategy, sustainability, infrastructure, powertrain development, and product benchmarking. The following examples illustrate how FEV combines system-level decision support with deep engineering expertise and product intelligence to address complex marine challenges.
Defining electrification strategy for future marine propulsion
A marine OEM sought to understand where electrification could create sustainable competitive advantage across its future product portfolio. Uncertainty around customer demand, technology maturity, and regional market developments made long-term product planning increasingly complex. FEV Consulting combined market assessments, customer requirements, technology evaluations, and competitive benchmarking to assess electrification potential across multiple vessel segments and regions. The analysis covered 30 boat types, 6 competitors, and 14 suppliers, creating transparency on market opportunities and technology pathways. The project enabled the client to prioritize target applications, define future system concepts, and establish a roadmap for future powertrain and product development investments.
Evaluating future fuel pathways under regulatory uncertainty
A group of marine stakeholders needed to determine which future fuel pathways could support long-term decarbonization targets while remaining technically and economically viable. FEV Consulting assessed alternative energy carriers including methanol, ammonia, hydrogen, electricity, and synthetic fuels through a combination of proprietary modeling, regulatory analysis, and technology assessment. Each pathway was evaluated against infrastructure requirements, technology maturity, sustainability impact, operational suitability, and economic performance. The project provided a structured decision basis for future fuel investments and enabled clients to define long-term decarbonization strategies despite significant uncertainty in regulation, markets, and technology development.
Managing technical risks in next-generation marine propulsion systems
An international marine propulsion manufacturer was developing next-generation electrified propulsion solutions and needed to evaluate technical and safety risks early in the development process. The introduction of high-voltage systems, battery technologies, and new propulsion architectures created significant challenges regarding system integration, reliability, and regulatory compliance. FEV Consulting conducted a comprehensive marine high-voltage risk assessment covering propulsion architecture, battery systems, and system integration concepts. The project identified approximately 70 hazards and defined more than 200 preventive measures to mitigate technical and operational risks. The resulting framework improved transparency on critical risk areas and provided a structured basis for the safe development and deployment of future marine propulsion technologies.
Benchmarking cutting-edge marine propulsion technologies
An international marine propulsion manufacturer sought a fact-based understanding of current product solutions, technology trends, and competitive positioning within electric marine propulsion systems. FEV Consulting disassembled and evaluated three electric propulsion systems down to cell level, generating complete transparency on technical design choices, component quality, performance characteristics, and cost drivers. The study generated more than 570 documented component and subsystem pictures and identified over 50 quality-related findings through four interdisciplinary expert workshops. The project enabled a detailed assessment of competitive strengths and weaknesses, providing a fact-based foundation for future product development, technology decisions, and investment priorities.
There is no ‘right’ fuel for marine decarbonization. Every option comes with trade-offs, and the challenge is to understand which solution actually fits a specific vessel, application, and operating profile.
Frequently asked questions
There is no universally optimal fuel for marine decarbonization. The most suitable option depends on application-specific factors such as vessel type, operating profile, required range, infrastructure availability, and regulatory requirements. FEV Consulting supports clients in comparing the trade-offs between methanol, ammonia, hydrogen, electrification, and synthetic fuels to identify the most viable pathway for a specific application.
Electrification is most viable in applications with limited range requirements, predictable duty cycles, and access to charging infrastructure, such as inland waterway vessels, ferries, and smaller recreational boats. For long-distance or high-power applications, hybrid solutions or alternative fuels are often more suitable due to current limitations in energy density and charging infrastructure.
Regulatory compliance can be optimized through early evaluation of fuel pathways, powertrain concepts, and operational strategies. Model-based assessments help compare alternative compliance scenarios and reduce the risk of both under-compliance and unnecessary cost exposure. FEV Consulting supports these evaluations by combining regulatory analysis with technical and economic modelling.
Benchmarking of current products provides critical insights into technology trends, cost structures, design trade-offs, and performance characteristics. Analyzing real hardware enables identification of best practices, potential risks, and differentiation opportunities, supporting more informed product and strategy decisions.
Future marine ecosystems require infrastructure that supports both existing and emerging vessel technologies. Depending on the application, this may include shore power, charging infrastructure, hydrogen or alternative fuel supply concepts, and integrated energy management solutions. FEV Consulting helps ports and maritime infrastructure stakeholders evaluate these options against long-term vessel, regulatory, and sustainability roadmaps.
