Argentine operator Buquebus is seeking to have the largest zero-emissions ferry after asking builder Incat Tasmania to switch its order for an LNG-fuelled vessel to an all-electric battery-powered design.

The Australian shipyard said recent consultations with Buquebus had led to Incat being “asked to investigate the possibility of replacing the LNG powerplant with a battery-electric solution”.

The 130-metre aluminium-built ropax, originally intended to be powered by LNG, will carry 2,100 passengers and 226 vehicles when delivered in 2025.
