DNV's Alternative Fuel Insights platform revealed that LNG dual-fuelled tonnage accounted for 51.6% of all alternative fuelled vessel orders in 2024, and an increase of 103% compared to 2023. Methanol dual-fuel newbuilds also saw a rise, with 166 orders, up 4%. Ammonia-fuelled ships saw a 238% increase, while LPG-powered vessels and hydrogen-fuelled ones were also in demand. The growth in alternative fuel vessels was driven by the container ship and car carrier segments, with 62% of all vessels contracted in 2024. LNG is the dominant fuel, with 691 vessels in service by the end of 2024, with the number set to double by the end of the decade. However, bunkering infrastructure remains under-developed, and the gap between demand and supply is expected to widen over the next five years.

The most recent data from DNV's Alternative Fuels Insights (AFI) platform indicates that orders for alternative-fuelled vessels increased significantly in 2024 due to the maritime industry's remarkable newbuilding year. A total of 515* such ships were ordered, representing a 38% year-on-year increase compared to 2023, underscoring the industry's growing commitment to decarbonization. The industry needs to work with fuel suppliers and stakeholders to ensure access to alternative fuels and ensure the safety of seafarers during this transition. DNV's Global Decarbonization Director, Jason Stefanatos, explains that market conditions, infrastructure development, fuel production updates, and cargo owners' needs influence fuel demand.

Wind energy, historically used for vessel propulsion, can be enhanced by combining recent technologies with Anton Flettner's large cylinders, which were developed in the 1920s. Flettner rotors are large cylinders that spin vertically, redirecting wind energy to propel large vessels through wind-swept oceans, reducing fuel consumption. They operate similarly to aerosol cans, requiring a small amount of pressure to release large amounts from storage. An electric motor spins the cylinder, generating massive propulsive thrust. Alternative methods for sustaining rotation exist, and this article discusses favorable geographic locations, related technologies, and wind turbines driving cylinders. The article also discusses related technologies and wind turbines driving cylinders.

Adani Ports and Special Economic Zone (APSEZ) has entered the global top 10 list of transportation and transportation infrastructure companies in the S&P Global corporate sustainability assessment (CSA) rankings for 2024, the company stated. APSEZ is the only Indian firm to feature in the rankings. Previously, it was ranked among the world’s top 15 transportation and transportation infrastructure firms in corporate sustainability. APSEZ has improved its sector ranking by three points to 97th percentile, with a score of 68 out of 100. The company achieved the highest scores in social, governance, and economic dimensions, including transparency, reporting, materiality, supply chain management, information security, cybersecurity, system availability, and customer relations.

Clarksons Research reports that in 2024, 50% of all tonnage ordered had alternative fuel capabilities, marking a record level of investment in newbuild ordering. A fifth of all orders had "ready" notations, indicating vessels designed for future retrofit with alternative fuels. The company reported 820 vessels ordered of 62.2m GT involving alternative fuel capability, a record level of investment compared to 727 orders of 52.1m GT excluding LNG carriers. Despite the rising trend of alternative fuel capable vessels and efforts to increase efficiency in the existing fleet, Clarksons estimates that shipping’s global greenhouse gas emissions will have increased by ~4% y-o-y in 2024 to over 1bn tonnes of CO2e on a well-to-wake basis.
