MAGPIE Green energy container demo

Green Energy Containers provide mobile, zero-emission battery power for inland vessels, enabling flexible electrification without fixed charging infrastructure. This is demo 7 of the MAGPIE project.

Electrification

Introduction

The Green Energy Container is a mobile battery solution designed to provide flexible, zero-emission energy to inland vessels. It offers an alternative to fixed charging infrastructure and supports the transition to cleaner maritime transport. The system enables vessels to operate on electricity without requiring permanent installations, making it particularly suitable for ports and terminals with limited electrification. The technology is already available in small quantities and can be scaled up, although cost and funding for battery packs remain a challenge. This factsheet outlines the value proposition, applicability, technical solution, and implementation roadmap for deploying Green Energy Containers in port and inland shipping contexts.

Value proposition

  • The system enables the use of zero-emission fuels and provides a flexible energy solution for inland vessels.

  • It can also be used for flexible shore power.

  • The technology is ready and available in small amounts, with potential for scale-up by 2030 and broader deployment by 2040.

Problem: Demonstration is difficult due to market uncertainty and the need for coordination among cargo owners, vessel operators, battery providers, and infrastructure managers. Battery containers are more expensive than fixed batteries and cannot be stacked due to safety and regulatory constraints. Many small players in the market lack the capacity to bear the costs.

Port applicability

• Large Container Ports/Hub Ports: Applicable where inland shipping is integrated into port logistics and flexible energy solutions are needed • Industrial Ports: Applicable if they support inland vessel operations and require mobile energy solutions • Smaller/Regional Ports: Potentially applicable if they serve inland shipping routes and lack fixed charging infrastructure • Other: Most relevant for ports with inland shipping activity and interest in mobile, containerized energy systems

Detailed description of the solution

  • Battery Containers

    Self-contained energy units that can be loaded onto vessels to provide electric propulsion without the need for fixed charging infrastructure.

  • Charging Interface

    Designed to connect with vessel systems for efficient energy transfer, reducing charging time compared to fixed batteries.

  • Deployment Model

    Containers can be distributed across terminals or ports and swapped as needed, supporting operational flexibility.

  • Safety Considerations

    Containers are subject to regulatory constraints such as stacking limitations due to safety and technical risks.

  • Operational Integration

    Suitable for smaller vessels operating on inland waterways. Not intended for large ships.

  • Energy Supply

    Enables the use of electricity instead of diesel, reducing GHG and NOx emissions.

  • Scalability

    Technology is available today in small quantities. Upscaling is possible but depends on battery cost and funding availability.

  • Use Case Expansion

    May also be used for flexible shore power delivery in ports lacking permanent infrastructure.
