The future-proofed container ship

摘要

What are the demands on a future-proofed container ship? Starting with the fuel systems, ABS has produced a study on the likely decarbonisation pathway from 2020 to 2050. ABS director of sustainability, at its Global Sustainability Center in Copenhagen, Jan Otto de Kat* described the main points that resulted from the study."The largest contribution towards decarbonisation will come from fuels," said Mr de Kat. "The three fuel pathways are light gas, heavy gas and bio synthetics." He explained that light gas encompassed those with a low carbon to molecule content such as LNG, bio-derived methane and hydrogen. "Hydrogen has a high energy density, no carbon but has other challenges," he said.Heavy gas includes LPG, methanol and ethanol; ammonia is the zero-carbon fuel in this category but with lower energy content. Bio synthetics are the derivatives of these fuels and come with a cost factor.
