The Lloyd’s Register Maritime Decarbonisation Hub’s Zero Carbon Fuel Monitor (ZCFM) report highlights the progress and challenges in the adoption of zero (or near-zero) carbon fuels in the maritime industry. Technology readiness levels for ammonia, biofuels, hydrogen, methane, and methanol have significantly improved, with vessels in the existing fleet and orderbook showing capabilities for these fuels. The report identifies vessels ready to use ammonia, methanol, and hydrogen, and notes the increasing trend of commercial trials and applications in the sector. However, areas requiring further development include safety protocols, crew training, and investment uncertainties like fuel availability and regulatory frameworks. Amelia Hipwell from the LR Maritime Decarbonisation Hub emphasizes the importance of ongoing advancements in fuel handling and storage for the industry's sustainable transformation. Despite challenges, the maritime sector is progressing towards wider adoption of zero-carbon fuels, with a commitment from Lloyd’s Register to support this transition.
