E/F Ellen’s second battery life
What a Danish ferry retrofit can tell us about the next phase of electric vessel operation
Container ships and Tankers
More than 80 percent of global trade by volume is transported at sea. Merchant vessels often operate on long routes and strict schedules, requiring dependable power systems that reduce emissions and meet increasingly strict environmental regulations. Energy efficiency has a major impact on operational costs, while downtime is costly since every hour out of service can disrupt supply chains and increase expenses for operators.
Battery systems for merchant ships must deliver high power for peak shaving, spinning reserve, load optimisation and transition, while recharging efficiently from onboard generators or shore power with minimal degradation. They need to perform consistently through thousands of cycles over long service intervals and under tough environmental conditions such as heat, cold, vibration, and salt exposure.
Echandia’s LTO battery systems optimize generator operations efficiently, recharge quickly, offer simple operation and maintain performance over many years, limiting crew burden. The chemistry is extremely stable and resistant to thermal runaway, which is crucial for ships carrying large crews and heavy cargo. The systems perform reliably in extreme temperatures and tolerate partial charging, making them a safe and dependable choice for hybrid propulsion and emissions compliance.
ENERGY EFFICIENCY
Lower fuel use with electrified spinning reserve
OPTIMISED LOAD
Keeps generators at optimal efficiency
SIMPLE AND STABLE OPERATION
Manage high demands when using heavy equipment, dynamic positioning and manoeuvring
LONG SERVICE LIFE
20,000+ cycles with minimal performance loss e requirements
CLASS-LEADING SAFETY
No thermal runaway, no fire risk

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.
