DNV has released the Energy Efficiency Measures and Technologies – Key solutions and strategies for maritime’s decarbonization journey report, which provides an overview of more than 40 energy-efficiency (EE) measures and details their fuel-saving effects, cost figures and suitability for specific ship types. It highlights how these measures can help shipowners meet short- and mid-term regulatory requirements, gain a competitive edge and ensure profitable operations well into the 2030s and 2040s.
Key takeaways
In the report, DNV explores a wide range of technical and operational measures, detailing cost considerations, suitability for different ship types, and the challenges of combining multiple solutions effectively. Digitalization also plays an important role, and the report offers insights into how data-driven decision-making can enhance fuel savings, while ensuring cybersecurity remains a priority.
DNV’s report outlines a three-step approach for managing decarbonization risks: defining greenhouse gas (GHG) trajectory and goals, assessing pathways for meeting these goals, and developing a fleet decarbonization strategy and plan. It also explores other solutions such as low-carbon and carbon-neutral fuels, biofuels, onboard carbon capture, fuel cells and nuclear propulsion, evaluating their benefits, challenges and emissions reduction potential.
DNV’s expert advice
Knut Ørbeck-Nilssen, CEO at DNV Maritime, said, “The decarbonization of shipping is one of our greatest challenges. While transitioning to carbon-neutral fuels is essential, supply and cost remain key barriers. 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.”
Jason Stefanatos, global decarbonization director at DNV, added, “Energy efficiency is key to reducing emissions and enabling low-carbon fuel adoption. While there’s no one-size-fits-all solution, improving onboard efficiency cuts emissions in the short term and accelerates low-carbon fuel adoption in the long term. Every percentage of fuel saved, whether conventional or alternative, translates into significant cost savings. EE is becoming critical, and the industry must raise awareness, gain knowledge and plan ahead.”
In related news, DNV’s research recently revealed that a total of 515 alternative-fuelled vessels were ordered in 2024, representing a 38% year-on-year increase compared to 2023. Click here to read the full story.
