Maritime Energy Transition: Innovations and Key Challenges
The electrification of maritime fleets and fluvial is now a major challenge in energy transition. During the AFBE (French Association for Electric Boats) technical day, which was held at the Paris-Yacht Marina, experts highlighted innovations related to electric and hybrid drive systems. This event was an opportunity to present technological solutions for recharging and powering ships, while addressing essential issues such as regulations, infrastructures and feedback on recent projects.
The advent of electric and hybrid systems for boats
The day started with a series of presentations on charging systems Of electric ships. Emphasis was placed on innovative fuelling solutions and on the evolution of international standards. Among the technologies put forward were connectors inspired by the automotive industry, such as standards CCS Combo and ISO 15118, which ensure both interoperability and security.
Automatic refill systems, such as reverse pantographs, were also presented. These technologies, already used for urban electric buses, make it possible to simplify dockside charging operations and to reduce human intervention.
Charging technologies for electric and hybrid boats
The electrification of boats is based on essential components:
- Onboard charger (OBC) : Located on board the ship, the on-board charger converts the alternating current (AC) supplied by the terminal into direct current (DC) to power the batteries. Modern OBCs support variable powers, generally ranging from 3.7 kW to 22 kW.
- Charge controller (EVCC) : This component ensures communication between the ship, the terminal and the battery. It manages security and optimizes the load by following standardized protocols such asISO 15118, European standard already widespread in the automotive world, and which integrates functionalities such as the Plug & Charge, or even the vehile to grid (V2G), offering prospects for future applications. Some OBC models already incorporate the functionalities offered by the EVCC.
- CCS Type 2 and Combo Connectors : These standardized connectors allow charging in AC (up to 43 kW) and DC (up to 350 kW). Their versatility makes them indispensable for modern infrastructures.
Feedback from Weenav
During the technical day, Antoine Bouchez, co-founder of Weenav, presented innovative solutions for integrating charging systems in electric motors. Weenav uses standards like ISO 15118 to offer solutions adapted to the different needs of maritime and river fleets.
- Standardized integration: Weenav systems include embedded chargers, charge controllers EVCC and connectors CCS Combo. These solutions guarantee fast, secure charging and in accordance with international standards.
- Adaptation to existing infrastructures: Weenav can intervene to optimize or modernize existing systems. This includes adding charging components, reducing operating costs, and improving energy performance.
- Flexibility for hybrid configurations: Weenav's solutions adapt to hybrid fleets, allowing for a gradual transition to The electric while reducing thecarbon footprint.
Prospects for maritime decarbonization
The AFBE event was also an opportunity to look back at the wider challenges of energy transition. The technological advances presented, combined with investments in infrastructure, provide a clear road map for decarbonize fleets.
With players like Weenav, who combine technical expertise and integration flexibility, the maritime sector is on track to meet the challenges associated withelectrification. Events such as the AFBE Technical Day help consolidate knowledge and accelerate this essential transition.
