Methanol bunker tank trailer: enabling flexible last-mile fuel supply

The transition to hydrogen-derived fuels requires flexible and reliable last-mile delivery solutions. The H2Deri@BSP methanol bunker tank trailer specification, provides a practical framework for deploying truck-to-ship (TTS) bunkering, supporting ports or energy companies in establishing efficient methanol supply chains.

From concept to procurement-ready solution

Developed by project partner Alexela AS, this deliverable defines a complete technical and operational specification for a methanol tank trailer, forming the basis for procurement and testing in project year two. It translates real port constraints such as maneuverability, safety, and regulatory compliance into a ready-to-use specification for Request for Quotation (RFQ) processes.

Technical overview: a practical and scalable bunkering solution

The specification provides a construction- and operation-oriented design, ensuring that the trailer can be directly implemented in port environments:

• Tank capacity and material: approx. 30,000 litres, stainless steel construction suitable for methanol transport
• Vehicle configuration: 4×2 truck-and-trailer setup, optimised for maneuverability in confined port areas
• Bunkering method: truck-to-ship (TTS) operations with defined transfer procedures
• Cargo handling systems: pumps, transfer connections, and safety equipment adapted from LNG best practices
• Safety systems: PPE requirements, safety checklists, and emergency procedures addressing methanol toxicity
• Regulatory compliance: alignment with ADR standards, UN 1230 classification, and CN code requirements for cross-border operations

These specifications are tailored to real port conditions (e.g. Tallinn and Helsinki), demonstrating that the solution is not theoretical, but directly applicable and scalable across Baltic Sea ports.

From operations to safety and standardisation

Beyond technical design, the deliverable includes a complete operational framework, covering the full bunkering cycle from pre-bunkering planning to post-transfer procedures. It also introduces standardised documentation and safety tools, such as checklists and delivery note templates, ensuring consistent and safe operations across ports.

The integration of risk assessment methodologies (HAZID/HAZOP) further strengthens the framework, enabling ports and operators to systematically identify and mitigate hazards associated with methanol handling.

Enabling ports to start with methanol bunkering today

The tank trailer concept represents a low-threshold entry point for ports beginning their transition to alternative fuels. Compared to fixed infrastructure, it offers flexibility, lower upfront investment, and adaptability to evolving market demand.

By combining technical specifications, operational procedures, and regulatory alignment, the deliverable provides ports and operators with a complete blueprint for implementing methanol bunkering in real conditions.
