Full retrofit to battery-electric operation

Why Öresundslinjen chose Echandia:

• 10-year minimum design life

• 2–3 times more compact than other chemistries, ideal for retrofit installations

• Fast-charging capability, full turnaround charging in just 11 minutes

• Class-leading safety, no thermal runaway, no fire risk

• Lower total cost of ownership, fewer replacements, reduced maintenance and downtime

Performance and integration

Most competing battery solutions offered an expected lifespan of around five years, requiring costly midlife replacements. Echandia’s battery system is designed for a minimum of ten years of operation under daily high-cycle use, cutting long-term costs and minimizing operational interruptions. Thanks to its compact footprint and lightweight design, the system could be integrated into the M/S Hamlet without major structural changes, which is a key advantage for retrofit projects where space is limited.

After evaluating multiple battery suppliers for this significant conversion project, the superior lifetime and lower weight of the Echandia battery system stood out as the primary reasons why Echandia emerged as the optimal choice for us.

Looking ahead

With rapid charging capability at both ports and a robust, long-life energy storage system, the M/S Hamlet retrofit is an important step toward sustainable, zero-emission operations on the Öresund Strait. Echandia’s fast-charging LTO technology demonstrates how high-frequency ferry routes can transition to full electrification without compromising performance or reliability.
