Danish container shipping giant AP Moller-Maersk is looking to order its first small containerships that can run on ammonia, methanol or ethanol within three years.

The world’s biggest liner group aims to order a series of baby boxships to operate within a specific region that will allow it to supply the vessels with the alternative fuel it chooses, chief executive Soren Skou told a podcast hosted by the Global Optimism climate change team.

Maersk is undertaking research into new fuels at its Maersk Mc-Kinney Moller Center for Zero Carbon Shipping.
