Direct Current Architecture Integration for Marine Power Systems

ABB and Ferrari Hypersail are collaborating to develop and implement advanced direct current (DC) electrical architectures for a 100-foot hydrofoil monohull. This cooperation focuses on deploying autonomous marine power systems capable of managing renewable energy generation and storage in highly demanding offshore environments.

Target Industries and Application Areas
The technical insights derived from this implementation target sectors requiring resilient electrical infrastructure, including marine transportation, data centers, and industrial microgrids. The primary use case involves operating a self-sufficient energy system that balances generation, storage, and power distribution in real time without external grid connections. By testing these systems under extreme offshore conditions, the partnership aims to improve the process stability, safety, and maintainability of isolated power networks.

Industrial Challenge and Cooperative Roles
Operating a vessel powered entirely by renewable energy requires continuous balancing of electrical loads against variable power generation. Ferrari Hypersail provides the physical testing platform—a hydrofoil operating in environments characterized by extreme cold, salt spray, pressure, and mechanical motion. ABB acts as the electrification partner, supplying engineering expertise based on its extensive background in direct current technology. This collaboration was necessary to integrate complex marine electrical systems with onboard renewable sources, a task requiring specialized knowledge in DC system integration and real-time monitoring.



Technical Solution and System Deployment
The core technical solution is a dual-voltage DC architecture that functions as an isolated microgrid. The system operates simultaneously at 48 V and 800 VDC, managing power routing for critical navigation instruments, foil controls, safety systems, and main propulsion. ABB is responsible for integrating intelligent power distribution and real-time monitoring protocols to ensure system resilience. The deployment involves engineering the electrical storage and distribution networks to remain fully functional and balanced during rapid shifts in environmental conditions and energy availability.

Expected Operational Impact
By implementing an 800 VDC microgrid, the system reduces conversion losses typically associated with alternating current networks, thereby maximizing the efficiency of onboard renewable energy utilization. "Hypersail is powered entirely by renewable energy," stated Enrico Voltolini, Project Leader at Ferrari Hypersail. "It must remain self-sufficient for weeks in some of the world’s most challenging ocean environments." The resulting operational data will be utilized to refine autonomous power management systems, directly supporting the development of next-generation infrastructure for industrial microgrids and localized renewable energy installations.
