CanUK vessel-to-grid (V2G) brings together UK and Canadian consortia working collaboratively to develop the world's first V2G project.
With real-world installations in both Plymouth (UK) and Halifax (Canada), the project will showcase V2G technology in contrasting environmental and operational conditions, demonstrating the ability of e-vessels to deliver key energy services that enhance energy security.
 

What is vessel-to-grid technology?

V2G technology allows electric vessels to export energy from their batteries back to the grid or to a designated site, contributing to energy flexibility and grid balancing.
This bi-directional flow of energy enables vessels to act as a vital energy resource when they are docked and not in active use, ensuring optimal energy management for stakeholders like ports, harbour operators, vessel owners, and grid network providers.

Key Objectives

  • Innovative V2G technology: Develop and implement bi-directional charging capabilities on electric vessels, allowing for energy transfer to and from vessel batteries.
  • Real-world testing: Install V2G technology in both Plymouth (UK) and Halifax (Canada), showcasing how the technology performs in different environments and operational conditions.
  • Energy services: Demonstrate how V2G can provide valuable grid flexibility services, increase energy security, and support the transition to cleaner, more sustainable energy solutions.
  • Interoperability: Enable the seamless integration of vessels, chargers, grid systems, and software management through key communication protocols.
  • Environmental and operational insights: Conduct lab testing to better understand the operational and environmental parameters of marine batteries, enhancing their performance in the maritime sector.
 

Innovation and technology development

The CanUK project seeks to adapt bi-directional technology from the automotive industry for use in the marine environment. This involves a thorough testing process, including:
  • Lab testing: Conducting detailed tests of batteries and equipment to assess the operational and environmental factors that impact marine battery performance.
  • V2G standards: Integrating V2G standards into RS Electric's 63 kWh workboats, with ongoing research and development focused on battery and drive solutions.
  • Platform integration: Developing a management platform that integrates all V2G components, ensuring interoperability between vessels, chargers, and grid systems.
