The owner of the TSS Earnslaw is considering replacing the historic steamship's coal-fired boilers with an environmentally friendly means of propulsion.
Queenstown company RealNZ has begun a feasibility study into alternatives ways of generating the steam that drives the vessel, which turns 109 today.
Chief executive Stephen England-Hall said theship's original boilers would soon need replacing.
It would be a "major and invasive piece of work" requiring the vessel to be out of the water for an extended time.
"That would be the obvious time to implement a carbon-neutral or carbon-zero solution," England-Hall said.
"We will essentially look for a new source of heat to generate steam that replaces the coal."
Carbon-neutral options were wood pellets or bio-diesel fuel, while carbon-zero options were renewable hydrogen fuel, battery-electric or fully-electric.
The Earnslaw is the oldest coal-fired passenger-carrying steamship in the southern hemisphere.
