According to DNV’s latest Maritime Forecast to 2050, achieving the International Maritime Organization’s (IMO) target of a 20% reduction in shipping emissions by 2030 will require significant advancements in energy efficiency. The report emphasizes the urgent need for action to enhance energy savings, especially as carbon-neutral fuels are limited and costly. To meet the IMO’s decarbonization goal, the shipping industry will need between 7 and 48 million tonnes of carbon-neutral fuels by 2030, but global production is projected to reach only 44 to 63 million tonnes, making it challenging for the maritime sector to secure its share.
The report highlights the importance of reducing energy losses as the most effective method for cutting emissions. Operational and technical measures could potentially lower fuel consumption by 4 to 16% by 2030, saving 40 million tonnes of fuel and cutting 120 million tonnes of CO2 emissions. The report also points to onboard carbon capture (OCC) as a promising technology for decarbonization, allowing the continued use of conventional fuels, but notes the need for substantial development of CO2 handling infrastructure. Alternatives like shore power and batteries are also emphasized as ways to decrease reliance on expensive carbon-neutral fuels.
Digitalization is identified as a key factor in enhancing energy efficiency in the maritime sector. The report highlights the importance of digital verification tools in providing vital data on vessel performance and the impact of energy-saving measures. This data-driven decision-making can be used to design the next generation of energy-efficient ships, crucial for the sector’s long-term success. Embracing digitalization, prioritizing energy efficiency, and leveraging technological solutions are key steps towards reducing the extra cost burden and achieving decarbonization goals in the shipping industry.
