Container ships and Tankers

Fuel saving merchant operations

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 need to deliver. Time after time.

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.

The safest choice

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.

Electrifying Copenhagen’s Commuter Ferries

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.

Fully electric RoPax ferry Nerthus

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.

Hybrid RoPax retrofit with Echandia LTO systems

Scandlines, one of Northern Europe’s leading ferry operators, has taken a major step toward zero-emission operation by converting two of its RoPax ferries into plug-in hybrids. The vessels are being retrofitted with Echandia Ultra battery systems, enabling up to 80% electric operation per crossing, with diesel propulsion retained only as backup.
