MAGPIE Ammonia Bunkering demo

Ammonia bunkering enables zero-carbon marine fuel supply, supporting shipping decarbonization while requiring new safety and infrastructure measures. This is demo 4 of the MAGPIE project.

Alternative fuels

Introduction

Ammonia bunkering refers to the process of supplying ammonia as a marine fuel to ships. As the maritime industry seeks sustainable alternatives to fossil fuels, ammonia has emerged as a promising zero-carbon fuel due to its high energy density and carbon-free combustion. Unlike conventional fuels, ammonia does not emit CO₂ when burned, making it a key candidate for achieving IMO decarbonization targets. However, its adoption requires significant changes in port infrastructure, safety protocols, and regulatory frameworks due to its toxicity and handling complexity. This factsheet outlines the value proposition, applicability, technical solution, and implementation roadmap for ammonia bunkering in ports.

Value proposition

  • Ammonia offers a scalable, zero-carbon fuel option for deep-sea shipping.

  • Developing ammonia bunkering infrastructure enables ports to become future-ready, attract green shipping lines, and contribute to global climate goals.

  • It also opens opportunities for innovation in fuel logistics, safety systems, and workforce training.

Problem: The maritime sector is under pressure to reduce greenhouse gas emissions and transition to low-carbon fuels. Traditional bunkering systems are designed for fossil fuels and are incompatible with alternative fuels like ammonia, which poses unique safety and handling challenges.

Port applicability

• Large Container Ports/Hub Ports: Highly applicable due to their capacity to invest in new infrastructure and attract large vessels transitioning to ammonia propulsion. • Ferry Terminals: Limited applicability; ferries typically operate short routes where ammonia may not be the most efficient fuel. • Industrial Ports: Strong applicability, especially where ammonia is already produced or handled as part of industrial operations. • Smaller/Regional Ports: Moderate applicability; may serve as secondary bunkering hubs or support regional ammonia supply chains. • Other: Applicable to energy ports and green shipping corridors where ammonia is part of broader decarbonization strategies.

Detailed description of the solution

  • Storage Tanks

    Cryogenic or pressurized tanks designed for ammonia containment.

  • Transfer Systems

    Pipelines, hoses, and couplings with corrosion-resistant materials and leak detection sensors.

  • Safety Systems

    Gas detectors, emergency shutdown systems, ventilation, and fire suppression tailored to ammonia hazards.

  • Digital Monitoring

    Real-time tracking of fuel transfer, pressure, temperature, and emissions using IoT and SCADA systems.

  • Training Modules

    VR/AR-based safety training for port workers and crew.

  • Operation

    Ammonia is delivered via truck, rail, or pipeline to port storage. Ships equipped with ammonia-compatible engines receive fuel through controlled transfer systems. Safety protocols ensure minimal risk to personnel and environment.
