Technology group Wärtsilä on Monday (20 February) published the Insight article “Methanol as marine fuel – is it the solution you are looking for?” to help ship owners and operators navigate the advantages and issues of using the product as a marine fuel. An excerpt of the article is as follows:

What is methanol?

Methanol (methyl alcohol, CH3OH or MeOH) is a biodegradable wood alcohol used to make everything from plastics to paints and pharmaceuticals. Although it is toxic and highly flammable, it dissolves in water and biodegrades quickly. Methanol has been used in industrial applications for over 100 years, but it’s now also showing great promise as a clean and sustainable future fuel for maritime applications.

What types of methanol are there?

Broadly speaking, methanol can be categorised into fossil-based methanol and renewable methanol. Fossil-based methanol is produced from coal or natural gas. Renewable methanol can be made from things like biomass or captured CO2 combined with green hydrogen.

What colour is methanol?

  • Methanol is a colourless liquid, but colour names are used to show what it’s made from:
  • Green methanol is made from biomass or captured CO2 and green hydrogen
  • Blue methanol is made using blue hydrogen in combination with carbon capture technology
  • Grey methanol is produced using natural gas
  • Brown methanol is produced using coal.

Green methanol is the most environmentally sustainable. Blue methanol still significantly reduces well-to-tank CO2 emissions compared to fossil fuels like diesel. One of the biggest challenges for maritime decarbonisation is that most methanol today is either grey or brown. All types of methanol could lead to a tank-to-wake CO2 reduction of about 7% compared to diesel. However, if we take the well-to-wake approach (from production to utilisation), the CO2 impact of grey and brown methanol is worse than that of diesel. This is why green and blue methanol are the only real alternatives when targeting well-to-tank GHG reduction.

Is methanol as fuel good for the environment?

The main benefit of green methanol is that it produces less CO2 than diesel combustion, as well as lower SOx and NOx emissions. The amount you can reduce emissions by will depend on the load your engines are running at. Studies have shown that, taking a tank-to-wake approach, by using methanol instead of heavy fuel oil (HFO):

  • CO2 emissions can be cut by 7%
  • SOx emissions can be cut by 99%, and
  • NOx emissions can be cut by 60%.

Methanol also biodegrades rapidly in water, which also makes it less of a risk to the environment than many alternatives.

Is methanol as marine fuel bad for the environment?

The CO2 footprint of methanol varies according to how it’s produced and transported, with fossil-based methanol generating more lifetime CO2 emissions than diesel. This makes green methanol the right choice for decarbonisation. Since the methanol molecule is the same whether it is grey, brown, blue or green, blending methanol is also a viable option to support the transition from conventional to renewable marine fuels.

How can methanol help with decarbonisation in shipping and the maritime energy transition?

The methanol molecule – CH3OH – is the same whether it is produced from grey, brown, blue or green feedstocks. This means you can blend it to help you transition gradually towards using a greater percentage of sustainable green methanol.

Is methanol expensive?

Compared to diesel operation, fuel expenses can be up to 15 times higher depending on the type of methanol consumed, its price and the share of energy provided by methanol. Although fuel expenses are higher with methanol than with diesel, this should be considered in terms of today’s regulatory environment. Vessels that fail to meet CII and EEXI targets will not be allowed to operate any longer. So the extra cost of the fuel should be compared not only with today’s fossil fuel price but with the cost of a brand new and more efficient ship and with the possible losses due to a mandatory stop of operations.

The Powerzeek Energy Platform has added methanol to its online marketplace in response to increased enquiries from shipowners. Powerzeek makes it easier for shipowners and trucking companies to find and buy cleaner fuels at the best available price.

Is methanol safe onboard ships?

From the perspective of onboard safety, there are well-established rules and regulations pertaining to the use of methanol as a marine fuel in the form of the IMO’s MSC.1-Circ.1621 – Interim Guidelines For The Safety Of Ships Using Methyl/Ethyl Alcohol As Fuel. Additionally, Wärtsilä has developed a safety concept for methanol engines that acts as an internal design guideline for all marine projects that involve using methanol as a fuel.

Where can I buy methanol as fuel for ships?

If you’re looking for methanol suppliers for ships, in 2020 the Methanol Institute confirmed that methanol was available at about 100 ports around the world.

Maritime-dedicated infrastructure for methanol transportation is still in the early stages of development but is expanding all the time.

Yang Ming orders six LNG dual-fuel, ammonia-ready containerships from Hanwha Ocean

Taiwanese shipping firm Yang Ming Marine Transport Corporation (Yang Ming) and South Korean shipbuilder Hanwha Ocean on Wednesday (2 September) signed a shipbuilding contract for six 13,000 TEU class LNG dual-fuel container vessels. 

The contract was signed by Dr. Chuck Tsai, Chairman of Yang Ming, and Mr. Charles Kim, CEO of Hanwha Ocean. The vessels are scheduled for delivery between 2028 and 2029. 

They will complement Yang Ming’s existing fleet of 10,000+ TEU vessels and serve as key vessels on East-West services, with deployment flexibility across trade lanes connecting Asia with the East and West Coasts of North America, South America, and the Mediterranean. 

Each of the six new vessels will have a capacity of up to 13,650 TEU and feature LNG dual-fuel propulsion and Ammonia Fuel Ready specifications.

“As Yang Ming transitions toward net-zero emissions, LNG provides a relatively mature and economically viable alternative fuel solution, capable of reducing greenhouse gas emissions by approximately 20%,” the company said. 

“At the same time, ammonia can serve as a carbon-free fuel by utilising converted LNG storage facilities, while offering relatively lower conversion costs and comparatively well-developed supply chains and infrastructure. The Ammonia Fuel Ready design will therefore provide Yang Ming with greater flexibility in responding to increasingly stringent international regulations on greenhouse gas emissions.”

In addition, the vessels will be equipped with Type B LNG fuel tanks with a design pressure of 1.0 bar to enhance the safety and efficiency of LNG operations, together with a range of energy-saving technologies, including Wind Shields, Rudder Bulbs, Pre-Swirl Stators, and Shore Power Systems. Smart ship technologies and cybersecurity protection features will also be incorporated to enhance operational efficiency, safety, and reliability while effectively reducing fuel consumption and greenhouse gas emissions.

Deliveries under Yang Ming’s next-generation fleet optimization plan commenced earlier this year. By 2030, a total of 24 new vessels are expected to enter service. 

This includes 18 LNG dual-fuel vessels—comprising five 15,500 TEU, seven 16,000 TEU, and the six 13,000 TEU vessels under this contract—alongside six 8,000 TEU methanol dual-fuel-ready ships.

LR, China’s MARIC unveil tanker concept ready for three future bunker fuels

Lloyd’s Register (LR) and the Marine Design and Research Institute of China (MARIC) on Thursday (3 September) have secured Approval in Principle (AiP) for a new 114,000 DWT product and crude oil tanker designed to accommodate future conversion to LNG, methanol or ammonia.

Announced at SMM 2026, the concept addresses one of the biggest investment challenges facing shipping today: the need to develop vessels and capabilities that can support a range of alternative fuel options and pathways as technologies, infrastructure and regulations evolve.

While LNG is already a mature fuel pathway, methanol and ammonia remain at an earlier stage of development, with questions around global fuel availability, infrastructure development, economics and long-term adoption.

The 114,000 DWT tanker concept has been designed as a product and crude oil carrier that can accommodate future conversion to LNG, methanol or ammonia as technologies, regulations and fuel supply chains mature. By incorporating conversion readiness at the design stage, the concept aims to reduce future retrofit complexity and provide owners with greater confidence when planning long-term fleet investments.

The design concept was reviewed against LR’s July 2026 class rules and regulations, including requirements relating to ships using gases and other low-flashpoint fuels, alongside relevant IACS Common Structural Rules for oil tankers. Final classification and statutory approval remain subject to full compliance with all applicable rules and regulations.

Theo Kourmpelis, Global Business Director for Tankers, Lloyd’s Register, said: “Shipowners are being asked to make major investment decisions today despite continued uncertainty around which fuels will dominate in the decades ahead. Alternative fuel solutions each offer potential pathways to compliance, but fuel infrastructure, regulation and economics continue to evolve at different speeds around the world.

“Designs that preserve flexibility will be critical in helping owners manage risk while preparing for multiple future scenarios.”

Si Nan, Marine & Offshore Marketing Department Vice Director, MARIC, said: “As the industry explores different decarbonisation pathways, shipowners need vessel designs that can adapt alongside technological and regulatory developments. This concept was developed specifically to provide greater fuel flexibility and long-term resilience, allowing owners to respond to changing market requirements without being locked into a single fuel strategy.

“Receiving Approval in Principle from Lloyd’s Register is an important milestone that validates the design concept and supports its future development.”

DNV: Alternative-fuelled vessel orders hit highest monthly level since October 2024

Latest data from classification society DNV’s Alternative Fuels Insight (AFI) platform alternative-fuelled vessel ordering was strong in August, with 52 new vessels added to the platform.

This is the highest monthly total since October 2024 and follows another active month in July, when 47 vessels were added to the database.

LNG-fuelled vessels accounted for the vast majority of August activity, with 46 orders recorded. The container segment led the way with 30 orders, while the car carrier segment contributed a further 12 LNG-fuelled vessels. In addition, four ethanol-fuelled bulk carriers and two hydrogen-powered bulk carriers were added during the month, as well as one LNG bunker vessel.

The strong summer performance marked a significant acceleration in ordering activity after a relatively slow start to the year. In total, 242 alternative-fuelled vessel orders have been placed in the first eight months of 2026, representing a 27% increase compared with the same period in 2025.

LNG remains the dominant fuel choice, accounting for 63% of all alternative-fuelled vessel orders registered so far this year. Container vessels represent the largest share of these LNG orders (59%), followed by car carriers (30%).

Jason Stefanatos, Global Decarbonization Director at DNV Maritime, said: “The past two months have been particularly strong for alternative-fuelled vessel ordering, with August recording the highest monthly total we’ve seen since October 2024. This has helped lift year-to-date orders to a level well above the same period last year.

“LNG remains the leading fuel choice, driven largely by activity in the container and car carrier segments. These sectors have been among the earliest adopters of alternative fuels, supported by predictable liner operations and increasing demand from cargo owners to reduce emissions across supply chains. 

“For many owners, LNG offers a combination of emissions reductions, fuel availability and future flexibility while the longer-term fuel landscape continues to evolve. 

“At the same time, the latest figures include orders for ethanol- and hydrogen-fuelled vessels, highlighting that owners continue to explore a range of decarbonization pathways. Different segments are making different fuel choices, but the overall level of activity demonstrates continued investment in lower-emission shipping.”
