Boat-To-Grid Technologies: Electrifying Marine Environments
Overview
Boat-to-Grid (B2G) technologies are emerging as a significant innovation in the electrification of marine environments. These technologies enable hybrid and electric vessels to not only consume energy but also supply it back to the electrical grid, thereby enhancing energy efficiency and reducing carbon emissions.
Key Developments
Volvo Penta's Initiatives
Volvo Penta is collaborating with Varberg Energi and Ferroamp to test B2G technology. This initiative aims to explore how hybrid and electric vessel batteries can support the electrical grid, particularly during peak demand periods. The technology allows vessels to act as mobile energy storage units, providing power back to the grid when not in use. The testing phase includes evaluating the performance of bi-directional charging systems, which enable vessels to both receive and supply energy. This could significantly reduce operational costs for vessel owners while contributing to grid stability. Source: Volvo Penta
Aqua SuperPower and BlueGrid Project
Aqua SuperPower and BlueGrid are leading the first transatlantic vessel-to-grid project, which aims to adapt automotive bi-directional charging technology for marine applications. This project, known as the CanUK project, involves deploying bi-directional chargers and electric vessels in both the UK and Canada. The project is designed to demonstrate the feasibility of using electric vessels to feed energy back into the grid, thereby cutting carbon emissions and enhancing energy efficiency in marine operations.

Environmental and Economic Benefits
The implementation of B2G technologies is expected to provide multiple benefits, including reduced greenhouse gas emissions, lower energy costs for vessel operators, and improved resilience of the electrical grid. By utilizing electric vessels as energy storage, the marine sector can contribute to a more sustainable energy ecosystem. The ability of electric boats to export energy to the grid during idle times can also help balance energy supply and demand, particularly in regions with high renewable energy penetration.
