TV4’s Kalla Fakta has made ten trips on the ferry over a seven-day period. On every trip, the ferry has been powered by diesel generators. According to the shipping company, the agreement with SL does not require the ferry to run on electricity, and the batteries are maintained according to the supplier’s instructions.
SL writes in a comment to TT that "fuel requirements have gradually been tightened during the agreement period and the vessels covered by the agreement today run on HVO (hydrogenated vegetable oil).
