LR identifies stumbling blocks for widespread adoption of methanol as marine fuel

As the shipping industry is seeing increased interest in methanol as a marine fuel, a new report from Lloyd’s Register (LR) has found pricing, availability and carbon accounting to be the main obstacles to its widespread adoption.

The report called “Fuel for Thought: Methanol” has identifed that the main challenges for the industry’s adoption of methanol are investment and community readiness, with the fuel’s technology feasibility continuing to grow.

It found that technology for methanol usage as a marine fuel is feasible, available and mature in certain cases, noting that most engine makers will have dual-fuel engine models in the near term and there is significant evidence of interest from shipowners. By 2030 it is estimated that methanol could account for 20% of the vessel orderbook.

The report showed that even though lower than technology readiness, community readiness for methanol is growing, with the industry drawing on the experience of transporting methanol as a cargo and its use as a fuel over the last decade.

Safe bunkering guidance has been written and has laid the groundwork for future international safety requirements and class regulations are in place for newbuilding and retrofit designs to ensure existing safety requirements are met by methanol-powered vessels.

The report, however, has identified that the biggest obstacles to the further development of methanol as a fuel relate to its pricing, availability and carbon accounting.

Due to the low production of green methanol and the current orderbook, availability could be a major issue for shipping with low supply driving up prices, LR explains.

Lack of methanol availability could also lead to questions as to whether the methanol produced will be certified as green, which ensures that the greenhouse gas (GHG) emissions are accounted for as part of a full lifecycle assessment. Currently, the majority of methanol produced at scale is sourced from natural gas and is not renewable.

The study also identifies why the energy density of methanol in comparison to current diesel and fuel oils could also present a stumbling block for its widespread use as a marine fuel. Vessels will require up to two and half times the amount of methanol than fuel oil for a specific consumption.

“Methanol’s time to shine as an alternative fuel candidate for the maritime energy transition is long overdue. Whilst there is no single fuel which will provide a ‘silver bullet’ for decarbonisation, methanol has the potential to play a key role in a multi-fuel future as part of the maritime industry’s ambition to decarbonise”, said Douglas Raitt, Lloyd’s Register’s Regional Advisory Services Manager for Asia.

“The Fuel for Thought report shows how crucial the commercial scale-up of green and blue methanol production is if the fuel is to be widely adopted by the maritime industry. We are, however, seeing positive signs with continued growth in technology and community readiness for methanol.”

The report is the first instalment in LR’s ‘Fuel for Thought’ series which will feature reports on ammonia, biofuels, carbon capture technologies, nuclear power, hydrogen, battery and electric power and the transition of LNG.  The series will analyse the safety, production, economic drivers, and technology of each energy source.
