OPINIONS ON GREEN SHIPPING

George Skevis, Sotiris Mamalis, and George Pontikakos stress the importance of
integrating multiple decarbonisation technologies effectively and highlight the need
for market-based measures beyond technical and operational solutions.

MARINE FUELS IS

DIFFICULT TO DEFINE

35% (almost one in three) of the survey participants
would invest in neither CO2 capture systems nor in LNG,
methanol or ammonia engines to improve the carbon
footprint of a newly built ship. Does this finding raise
concerns about the pace of the industry’s decarboni-
sation?
Not really. Firstly, significant advances in decar-
bonisation are already being made through
operational measures such as slow steaming,
weather routing, performance monitoring, etc.
Moreover, existing vessels or newbuildings with
conventional engines can utilise liquid biofuels
that are becoming increasingly available and
affordable as marine fuels. These biofuels have
a low lifecycle carbon footprint, helping vessels
comply with future IMO and EU regulations.
Finally, methanol and ammonia engines must
be proven in practice before shipowners and
operators choose them as their preferred tech-
nologies. LNG engines are more advanced in this
respect. In the case of onboard carbon capture,
uncertainties in the regulatory landscape and
by George Skevis, the absence of a CO2 value chain are additional
