Wasaline's ferry's pack grew from 2.2 to 12.6MWh, which is expected to cut the ship's energy use by approximately 10,000MWh/year.

The installation of AYK Energy's lithium iron phosphate batteries was carried out by Tallinn Shipyard, while dry-docking works took place at the Turku Repair Yard (both part of BLRT Grupp).

Wasaline's original intention was to make its operations fully carbon-neutral by 2030, a goal ticked off last year by switching Aurora Botnia's bunker supply to bioLNG.
