E/F Ellen’s second battery life
What a Danish ferry retrofit can tell us about the next phase of electric vessel operation
Navy
Navy ships place exceptionally high demands on their power systems. They need guaranteed availability for missions with systems that remain safe and reliable under extreme conditions. Safety is even more critical than in civilian vessels since any failure can compromise both operations and crew. Many naval vessels operate in remote areas where repairs or replacements are difficult, so power systems must deliver dependable performance for many years.
Battery systems for navy ships must deliver very high bursts of power for short periods, for example during silent running or rapid maneuvers. They may remain idle for long durations, then are required to operate at full capacity instantly. They must meet strict military standards and certifications and be easy to maintain with limited crew intervention.
Echandia’s robust LTO battery systems are designed for military and naval applications. They deliver high power safely, with minimal degradation even after years of use. The chemistry is inherently safe, offering excellent stability and resistance to thermal runaway. This ensures predictable operation in both low and high temperatures, essential for mission success in challenging environments.
Echandia’s battery systems have undergone extensive testing to meet the toughest defense standards. Their reliability, safety, and predictable behavior make them a preferred choice for naval applications where mission success and crew safety are paramount. Echandia has already delivered multiple systems to NATO member countries, demonstrating unmatched safety and robustness in real-world operations.

In 2020, a new fleet of electric commuter ferries was introduced in Copenhagen, setting a global benchmark for emission-free public transport on water. To meet the demanding requirements of inner-city passenger operations, Echandia was selected to supply the maritime battery system enabling safe, reliable, and fully electric propulsion.

In 2026, San Francisco Bay Ferry will introduce the United States’ first fully electric, high-speed, high-capacity ferry fleet as part of the Rapid Electric Emission Free (REEF) program. The project represents a major milestone for zero-emission maritime transport in North America.

In June 2025, Molslinjen introduced Nerthus, a fully electric RoPax ferry serving the route between Ballen on Samsø and Kalundborg in Denmark. The vessel is the first of two new electrified ferries commissioned by Molslinjen and built at Cemre Shipyard in Turkey.
Our team has worked with leading shipyards and system integrators, from ABB to Siemens, to electrify ferries, tugs, navy and transport vessels. We know what it takes to build a safe, durable system that performs every day.
