Port of Tanjung Pelepas, Advancing Green Fuel Bunkering for Maritime Decarbonization (Port of Tanjung Pelepas, 2023; 2026)

The Port of Tanjung Pelepas (PTP) in Malaysia represents an emerging case of how ports can position themselves at the forefront of maritime decarbonization through the adoption of low-emission technologies and future fuels. Strategically located along one of the world’s busiest shipping corridors, PTP is well placed to support the transition toward alternative marine fuels, particularly as global shipping accelerates efforts to reduce greenhouse gas emissions in line with International Maritime Organization (IMO) targets.

Central to this transition is the development of green fuel bunkering capabilities, with methanol identified as a leading candidate. A 2023 study supported by the Australian Government’s Partnerships for Infrastructure reported that methanol was then attracting the greatest level of investment from global shipping lines among green fuel options. PTP completed its first methanol bunkering operation at anchorage with Maersk in the fourth quarter of 2024, followed by LNG bunkering with Hapag-Lloyd in 2025 (Port of Tanjung Pelepas, 2026). The fuel pathway (fossil, bio or e-methanol) was not stated in the source. For PTP, this creates a strategic opportunity to develop bunkering infrastructure that aligns with evolving vessel fuel preferences while capturing future demand in a competitive regional market.

As a high-throughput container port with strong connectivity to global trade routes, PTP offers scale advantages that can support commercially viable bunkering operations. Its participation as a partner in a pilot study on zero-carbon bunkering, requested by Malaysia's Ministry of Transport, demonstrates proactive planning.

From an engineering and operational perspective, future fuel readiness requires flexible and modular infrastructure design. Methanol bunkering, for example, necessitates specialized storage tanks, safety handling systems, and compatibility with vessel refuelling interfaces. By incorporating adaptability into terminal layouts and fuel supply chains, ports can accommodate multiple fuel types over time, including ammonia and other low-carbon alternatives, reducing the risk of technological lock-in. These are general design considerations, not a description of installed PTP infrastructure. This flexibility is critical given the uncertainty surrounding which fuels will dominate long-term maritime decarbonization pathways.

Collaboration is also a key enabling factor. On 29 October 2025, PTP signed a memorandum of understanding with the Port of Melbourne covering knowledge exchange on decarbonization strategies, alternative fuel infrastructure development and regulatory collaboration on low-emission maritime fuels (Port of Tanjung Pelepas, 2026). Such partnerships help de-risk early investments, build market confidence, and accelerate the establishment of green shipping corridors, where vessels can reliably access low-emission fuels along key trade routes.

Importantly, the development of green fuel bunkering directly contributes to reducing the environmental impact of maritime logistics. Shipping currently accounts for approximately 3 per cent of global greenhouse gas emissions, and the IMO has set targets to significantly reduce emissions by 2050. By enabling vessels to transition to lower-carbon fuels at scale, ports like PTP play a critical role in supporting industry-wide decarbonization while maintaining efficient global trade flows.

Overall, the Port of Tanjung Pelepas illustrates how strategic investment in future fuels and bunkering infrastructure can enhance both environmental performance and long-term competitiveness. By aligning infrastructure development with emerging fuel technologies, fostering cross-industry collaboration, and leveraging its geographic advantages, PTP has the potential to become a regional hub for green marine fuels, supporting the transition to a low-carbon maritime sector across Southeast Asia and beyond.
