Jorg Erdmann estimates that it will take until 2025 before there is worldwide LNG bunker coverage.

Hapag-Lloyd’s senior director of sustainability accepts that LNG fuelling might be available by 2020 in major ports such as Rotterdam, but says the big challenge is the robustness of the infrastructure on the main shipping routes.

Erdmann says Hapag-Lloyd wants to get the technical experience of converting an LNG-ready ship to use the fuel.
