Ship Energy Efficiency

Growing pressure for maritime decarbonization  

Maritime decarbonization targets have been set and pressure is mounting across shipping to deliver greenhouse gas (GHG) reductions. Regulations like EU ETS and FuelEU Maritime are now putting a price on emissions, with similar legislations set to be implemented by the IMO in 2027, while additional pressure from cargo owners and society at large are driving shipowners to deliver real emissions reductions today. 

Ultimately, full decarbonization is expected by around 2050 and this will not be achieved without the large-scale transition to carbon-neutral fuels. However, getting the global fleet to transition to these new fuels will take many years so alternative solutions must be explored.

Role of energy efficiency in bridging the gap

Energy efficiency can bridge the gap. A range of innovative, practical, and effective technologies are available today which can increase the energy efficiency of vessels, decrease net energy input and fuel demand, and drive significant reductions in emissions. At the same time, implementing these measures can potentially reduce emission costs related to regulations like EU ETS and FuelEU Maritime.  

In the latest version of DNV’s Maritime Forecast to 2050 report, it was estimated that energy efficiency can deliver fuel savings and emissions reductions of up to 16%. This is equivalent to decarbonizing 55,000 of the smallest or 2,500 of the largest ships in the global fleet. If reached, it can contribute the bulk of emissions reductions necessary to reach the first of the IMO’s decarbonization goals, namely a 20% reduction in emissions compared to 2008 levels, by 2030.  

It is, therefore, imperative that shipowners explore all operational and technical energy efficiency solutions available today and find the best solution for their fleet.
