Port bunkering mapping: a practical instrument for alternative fuel deployment

The introduction of hydrogen-derived fuels in ports requires not only infrastructure, but also clear spatial planning and decision-making tools. The H2Deri@BSP Port Bunkering Mapping Instrument provides a structured methodology to identify, assess, and visualise suitable bunkering locations within ports, supporting the transition to climate-neutral shipping.

From complexity to clarity: mapping bunkering feasibility

Ports face increasing complexity when introducing alternative fuels such as methanol, ammonia, and hydrogen. The instrument addresses this by offering a comprehensive catalogue of criteria that enables ports to systematically evaluate where and how bunkering operations can be safely and efficiently implemented.

It supports multiple stakeholders like port authorities, bunker suppliers, and shipping companies, by acting as a planning, analysis, and communication tool that helps to align with technical, regulatory, and operational considerations.

Approach to the Instrument

The Port Bunkering Mapping Instrument provides clear and actionable insights by comprehensively considering the foundational aspects of:

• Criteria catalogue: A structured checklist covering regulatory, safety, spatial, and operational requirements for bunkering
• Site evaluation and scoring: Systematic assessment of potential bunkering locations based on predefined criteria
• Safety integration: Embedding safety analysis, including safety zones and risk-based assessments, directly into site selection
• GIS-based mapping: Use of geospatial data (e.g. berth locations, infrastructure, water depth, proximity to sensitive areas) to visualise feasibility
• Bunker case modelling: Linking location, fuel type, vessel characteristics, and transfer method into realistic operational scenarios

This approach enables ports to move from abstract planning to data-driven decision-making, identifying not only suitable locations, but also constraints, risks, and required mitigation measures early in the process.

A structured instrument: criteria, mapping and safety integration

At its core, the instrument translates complex requirements into a practical, structured mapping approach, including:

• Location-based criteria: regulatory requirements, accessibility, navigation constraints, and proximity to critical infrastructure
• Operational considerations: SIMOPS, traffic interactions, and environmental conditions
• Bunkering case parameters: fuel type, transfer methods (ship-to-ship, truck-to-ship, shore-to-ship), and operational limits
• Safety integration: risk assessments, safety zones, and compliance with international and local regulations

These elements are organised into a criteria catalogue and scoring system, allowing ports to compare potential sites, identify constraints, and prioritise suitable bunkering locations.

From instrument to application across EU ports

While developed based on real-world experiences such as the Port of Hamburg, the instrument is designed as a generalised and transferable framework, ensuring applicability across EU ports. It supports early-stage planning, approval processes, and the development of bunkering infrastructure needed for green shipping.

Importantly, the instrument lays the foundation for future digital tools, including interactive mapping solutions that will enable stakeholders to quickly identify feasible bunkering sites and streamline decision-making.

A living tool: testing and further development

The current deliverable is marked as a draft version, as the instrument will be tested and refined in real port environments during the second year of the project. This iterative approach ensures that the final tool reflects practical needs and operational realities. Click here to download the Port bunker mapping instrument development and application report.
