How does methanol compare to LNG regarding bunkering?

Oct 28,2025

When it comes to alternative marine fuels, methanol and liquefied natural gas (LNG) are two prominent options gaining traction in the shipping industry. Both offer potential benefits in terms of reduced emissions and compliance with stricter environmental regulations. However, their bunkering processes differ significantly. The Methanol Fuel Supply System (MFSS) presents several advantages over LNG bunkering, particularly in terms of storage, handling, and infrastructure requirements.

As the maritime industry seeks cleaner fuel alternatives, methanol emerges as a promising solution. Its compatibility with existing bunkering infrastructure and lower investment costs for both ports and vessel operators make it an attractive option. Let's delve deeper into the comparison between methanol and LNG bunkering to understand why methanol is gaining momentum in the shipping sector.

Methanol Fuel Supply System Proven Track Record

Methanol vs LNG: Storage and handling differences

Physical properties and storage requirements

Methanol and LNG have distinct physical properties that significantly impact their storage and handling processes. Methanol is a liquid at ambient temperature and pressure, while LNG must be kept at extremely low temperatures (-162°C) to remain in its liquid state. This fundamental difference leads to contrasting storage requirements and bunkering procedures.

For methanol storage, conventional tanks with minor modifications can be used. These tanks don't require the extensive insulation or specialized materials needed for LNG storage. The Methanol Fuel Supply System can be integrated into existing ship designs with relative ease, often utilizing space more efficiently than LNG systems.

Safety considerations during bunkering

Safety protocols for methanol and LNG bunkering differ due to their unique properties. Methanol bunkering can be conducted using procedures similar to those for conventional marine fuels, with additional precautions for its low flashpoint and toxicity. LNG bunkering, however, requires more complex safety measures due to the risks associated with cryogenic liquids and potential gas leaks.

The MFSS incorporates safety features designed to mitigate risks associated with methanol handling. These include leak detection systems, proper ventilation, and emergency shutdown mechanisms. While both fuels require careful handling, the familiarity of liquid fuel handling gives methanol an advantage in terms of crew training and operational safety.

Cost-effectiveness: Methanol bunkering infrastructure advantages

Infrastructure investment comparison

The cost of establishing bunkering infrastructure is a crucial factor in the adoption of alternative fuels. Methanol holds a significant advantage over LNG in this regard. Existing liquid fuel infrastructure can be adapted for methanol bunkering with relatively minor modifications, resulting in lower investment costs for ports and terminals.

LNG, on the other hand, requires substantial investment in specialized cryogenic storage tanks, transfer systems, and safety equipment. The high costs associated with LNG infrastructure development can be a barrier to widespread adoption, particularly for smaller ports or those with limited resources.

Operational flexibility and adaptability

The Methanol Fuel Supply System offers greater operational flexibility compared to LNG systems. Methanol can be stored in conventional tanks, allowing for easier integration into existing vessel designs. This adaptability extends to bunkering operations, where methanol can be transferred using standard pumps and hoses with appropriate safety measures.

LNG bunkering requires specialized equipment and procedures, limiting the number of ports capable of providing this service. The simpler logistics of methanol bunkering enable more ports to offer the fuel, potentially reducing operational constraints for ship operators and improving route flexibility.

Environmental impact of Methanol Fuel Supply System

Emissions reduction potential

Both methanol and LNG offer significant emissions reductions compared to conventional marine fuels. However, the environmental impact of the MFSS extends beyond just combustion emissions. The production and transportation of methanol can be achieved through various pathways, including renewable sources, offering the potential for a lower overall carbon footprint.

Methanol combustion produces no sulfur oxides (SOx) and significantly reduced particulate matter emissions. While both methanol and LNG result in lower carbon dioxide (CO2) emissions compared to heavy fuel oil, methanol has the advantage of being easier to handle in case of spills, with less severe environmental consequences than LNG leaks.

Life cycle assessment considerations

When evaluating the environmental impact of marine fuels, it's essential to consider the entire life cycle, from production to end-use. The Methanol Fuel Supply System, when coupled with renewable methanol production, offers a pathway to significant greenhouse gas reductions. This "well-to-wake" approach highlights methanol's potential as a sustainable marine fuel option.

While LNG also provides environmental benefits, concerns about methane slip during production, transportation, and use can offset some of its advantages. Methanol, being a liquid at ambient conditions, is less prone to fugitive emissions during handling and storage, contributing to its overall environmental performance.

Conclusion

In comparing methanol to LNG for bunkering purposes, it's clear that both fuels offer advantages over traditional marine fuels. However, methanol emerges as a particularly attractive option due to its simpler storage and handling requirements, lower infrastructure investment needs, and potential for renewable production.

The Methanol Fuel Supply System provides a practical solution for ship operators looking to reduce emissions and comply with stringent environmental regulations. Its compatibility with existing infrastructure and familiar handling procedures make it an accessible option for a wide range of vessels and ports.

As the maritime industry continues to seek sustainable fuel alternatives, methanol's versatility and potential for carbon-neutral production position it as a promising contender in the transition to cleaner shipping. The ongoing development and implementation of MFSS technology by companies like TSC further solidify methanol's role in the future of marine propulsion.
