LNG might not be considered an alternative fuel for the long term by the researchers at UMAS, which last month wrote a report for The Getting to Zero Coalition, but they think the way it has been adopted as a bunker fuel can act as a model for greener propulsion technologies.

In the report — Strategy for the Transition to Zero-Emission Shipping — the authors said "the adoption of LNG as a marine fuel has many components which would likely exist in future marine fuel transitions that, therefore, make it a valuable case study".
