The European research initiative HARPOONERS is working on advanced high-voltage battery storage systems designed for maritime and inland waterway vessels. The project focuses on a modular and flexible AC battery system that integrates directly with onboard power electronics and networks, including high and medium voltage systems.
The initiative aims to enhance adaptability by ensuring compatibility with both existing and future battery cell technologies, regardless of their chemical composition. The project is targeting practical applications with storage capacities between 5 and 10 MWh, supporting both all-electric and hybrid propulsion systems.

To optimize performance and safety, HARPOONERS incorporates real-time monitoring through a distributed battery management system (BMS) at the battery level and an energy management system (EMS) at the system level. A digital twin links these control systems with edge cloud interfaces for predictive analysis. Additionally, cybersecurity measures are being developed to ensure safe operation.
A consortium of 13 partners from four EU countries—Spain, Belgium, Austria, and Italy—along with three associated countries—Norway, the United Kingdom, and Turkey—is involved in the project. The initiative is coordinated by Fundacion Tecnalia Research & Innovation from Spain, with participation from organizations such as AIT Austrian Institute of Technology, Vrije Universiteit Brussel, and Corvus Energy AS.
