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 ERS3 LTO battery systems, enabling up to 80% electric operation per crossing, with diesel propulsion retained only as backup.
The project is one of Echandia’s largest retrofit installations to date, both in system size and project value, representing a significant milestone in large-vessel hybridization.

Why Scandlines chose Echandia:
10-year design life, double that of conventional systems
2–3 times more compact than alternative chemistries
Class-leading safety, with no thermal runaway or fire risk
Efficient retrofit integration, requiring the removal of only one diesel engine instead of two
Space efficiency and integration
A key challenge in hybrid retrofits is limited engine room space. Echandia’s compact LTO-based battery systems required only half the installation space of comparable systems. This made it possible to meet Scandlines’ performance goals without compromising vessel layout or cargo capacity.
While other solutions would have required removing two diesel engines, Echandia’s system achieved the same energy output by removing just one, a crucial factor in making the retrofit feasible.
This project shows what’s possible when you combine forward-leaning operators with the right technology partner. Our system’s space savings and long lifespan were key to making this retrofit a reality

Looking ahead
The Scandlines hybridization project demonstrates how advanced energy storage can extend vessel lifetime, reduce fuel consumption, and pave the way for full electrification. With Echandia’s LTO technology, Scandlines gets a solution that is safe, compact, and built to last, marking an important step toward practical zero-emission operation on large RoPax ferries.
