DNV report assesses fuel-efficiency measures

A new report from DNV investigates the energy-efficiency gains generated by more than 40 measures that ship operators can now adopt as they strive for greater sustainability.

The classification society’s report, “Energy-efficiency measures and technologies – Key solutions and strategies for Maritime’s decarbonization journey”, examines potential fuel-saving gains, costs, suitability for specific ship types, and the likely impact on shipowners’ aims to meet short- and mid-term regulatory requirements. The report also reveals how owners can gain a competitive edge and ensure profitable operations into the 2030s and beyond.

DNV Maritime CEO, Knut Ørbeck-Nilssen, identified the decarbonisation of shipping as one of the sector’s greatest challenges. “While transitioning to carbon-neutral fuels is essential, supply and cost remain key barriers,” he said. “To accelerate this shift, all possible measures must be explored. Energy-efficiency measures can not only cut emissions in the short term but also support the adoption of alternative fuels by reducing overall fuel demand and operational costs. With many such measures available, our report aims to help stakeholders navigate these choices and identify the best solutions for their fleets.” 

The report outlines a three-step approach for managing decarbonisation risks: defining greenhouse gas (GHG) trajectory and goals, assessing pathways for meeting these goals, and developing a fleet decarbonisation strategy and plan. It also explores other solutions such as low-carbon and carbon-neutral fuels, biofuels, on-board carbon capture, fuel cells, and nuclear propulsion, evaluating their benefits, challenges, and emissions reduction potential.
