Chris Chatterton, Maritime Advisor of Global Centre for Green Fuels (GCGF), believes ethanol should have a seat at the alternative bunker fuel table and he shares with Singapore-based bunkering publication Manifold Times why it deserves to be part of the conversation: 

MT: Tell us a little about GCGF, when it started and its mission.

The Global Centre for Green Fuels, or GCGF, is a non-profit global think tank headquartered in Singapore. We were established in 2024 to accelerate the adoption of sustainable fuels across maritime, aviation, and land transport. Our work focuses on enabling real-world deployment of low-carbon solutions through data-driven policy, technical validation, and strategic industry collaboration. We help stakeholders – from regulators to shipowners – navigate decarbonisation challenges with practical, scalable fuel strategies.

MT: As its maritime advisor, why do you think ethanol should be considered as an additional maritime fuel?

Ethanol presents a pragmatic pathway to decarbonise shipping. It’s widely available globally, competitively priced, and can be used with existing methanol dual-fuel engine platforms – often with minor re-calibration. Importantly, ethanol offers very low lifecycle emissions, whether derived from crops, waste or lignocellulosic biomass. Ethanol’s clean combustion profile also helps reduce local air pollutants like SOx and PM (particulate matter). Given the urgency of the IMO’s 2030 and 2050 decarbonisation targets, ethanol stands out as an immediate, scalable, and practical solution.

MT: What’s the current status of the push on ethanol following the document submission, highlighting the use of ethanol as a marine fuel, from Brazil and IBIA at IMO MEPC 83?

That submission was a critical milestone. It called for three main actions: a) inclusion of ethanol in the GESAMP LCA Working Group for lifecycle assessment, b) a request for ISO to develop a marine fuel standard for ethanol, and c) updates to the IGF Code to reflect ethanol-specific safety and operational differences from methanol. The submission was well received and is now being processed through relevant sub-committees like CCC and MSC. GCGF is supporting this by coordinating technical input and promoting pilot demonstrations and engine testing.

MT: With lots of focus on LNG, methanol, ammonia and hydrogen as part of the future marine fuel mix, why do you think there hasn’t been much talk on ethanol and what do you think needs to be done to ensure it is part of the alternative fuel pool?

The ethanol story in shipping is just now being told. Other fuels have had strong industry backing and early movers, whereas ethanol’s benefits – such as its wide availability and infrastructure compatibility – haven’t been highlighted enough for maritime use. What’s needed is greater awareness, technical standardisation, and real-world demonstrations. Ethanol can be bunkered through the same terminals and handled with very similar safety protocols as methanol. Singapore, being a global maritime hub, can play a pivotal role in advancing ethanol’s case through bunkering, pilots and green corridors.

What are the challenges to achieve widespread adoption of ethanol as a marine fuel in terms of production, fuel availability, safety, and long-term viability and how can they be overcome?

Global ethanol supply is already robust – almost 100M mtpa currently – mainly from the U.S., Brazil, Europe, and a growing number of producers in Asia. That’s enough to support near-term maritime demand. Safety-wise, ethanol is classified as a low-flashpoint fuel, similar to methanol, and requires careful handling – something the industry is already accustomed to. Long-term viability depends on sustainability certification, cost competitiveness, and standardisation – all areas GCGF is working to address. The potential is there – it just needs the right regulatory and commercial framework.

MT: As the IMO’s IGF Code already includes methyl/ethyl alcohols as marine fuel, are there specific advantages in using ethanol vs methanol? What are the specific risks of ethanol, compared with methanol?

While it’s true that ethanol has a low flashpoint similar to methanol and as addressed in the IMO IGF Code, it’s important to note that methanol’s flash point, already in use as a marine fuel, is slightly lower. So low flashpoint alone isn’t a disqualifier, it’s a characteristic that must be managed through proper standards and safety protocols. Importantly, ethanol has a significantly lower toxicity risk than methanol, making it safer for crew handling, spill and salvage scenarios.

Ethanol has lower energy density than fuel oil, but higher than methanol, which makes it slightly more efficient too.  Therefore, what is needed is a robust, ethanol specific ISO standard that accounts for its unique properties such as water miscibility, energy content, and ignition characteristics. Importantly, ethanol also carries significantly lower toxicity risks than methanol, making it safer for crew handling and spill scenarios.

Interim IMO guidelines already acknowledge ethanol alongside methanol, and class societies have started aligning with these. But we still require marine-specific test protocols, safe handling/safety training, and OEM validation to close the gap and highlight the slight differences between methanol and ethanol as ship fuels. This is a key agenda item for us at GCGF in 2025–2026.

MT: Do engines and tanks on ships need to be modified to use ethanol? How easy or difficult is it to adopt ethanol as a marine fuel?

It’s surprisingly straightforward. Modern dual-fuel engines designed for methanol and electronically controlled – like the Wärtsilä W25, W32, the Everllence (MAN) LGI series and several WindGD models – can be re-calibrated to ethanol with minimal hardware changes. It’s mainly a software calibration and minimal adjustments in the fuel supply system. Several leading OEMs have confirmed this compatibility, and we’re now working with engine OEMs to initiate formal testing and trials. The real opportunity lies in making ships “alcohol-ready,” giving owners flexibility between methanol and ethanol based on cost, supply, and route-specific decarbonisation goals.

Additionally, technology is driving the ability to equalise energy storage on board with the inclusion of Sandwich Structured Cofferdams, enabling lower energy density fuels such as methyl/ethyl alcohols to be bunkered on a Fuel Oil  energy-equivalent basis.

MT: With growing interest in cleaner fuels, what are the sustainable advantages of the production of ethanol?

Ethanol supports both climate and energy security goals. Today’s production combines regenerative and precision agriculture with advanced biorefining technologies, resulting in exceptionally low carbon intensity ethanol, on par with or better than many synthetic fuels. It’s also a liquid fuel, meaning it can readily leverage existing bunkering and storage infrastructure. On a macro level, ethanol production supports rural economies, energy security by reducing fossil fuel dependence, and creates a unified supply chain for land, sea, and air transport – as we’re already seeing in places like Brazil, India, and potentially Japan.

China’s bunker market reshaped by tax rebates, trade flows and refining changes, says economist

Dr Kang Wu discusses how China’s bunker fuel tax rebate, shifting refinery output, import flows and alternative fuel adoption are reshaping the country’s marine fuels market and its competitive position.

China’s growing role in the marine fuels market is reshaping the competitive dynamics between Chinese bunkering hubs and established centres such as Singapore.

 In this interview with Manifold Times, Dr Kang Wu, Energy Economist specialising in China and Southeast Asia at Global Energy Research and Educational Training Pte. Ltd., discusses the impact of China’s bonded bunker fuel tax rebate, domestic refining and import trends, the adoption of LNG and methanol, and pricing differentials with Singapore, while also examining China’s surplus of UCOME:

MT: How has China’s 2020 VAT rebate policy for bonded bunker fuel, especially for low-sulphur fuel oil, affected the competitiveness of Chinese ports like Zhoushan in comparison to traditional hubs like Singapore?

The impact has been significant, mainly because the rebate extends beyond the VAT. Effective February 2020, the Chinese government introduced a rebate policy for the 13% VAT on China’s fuel oil exports (including bunker fuels) to bonded areas. More importantly, the rebate also covers the fuel oil consumption tax, which amounts to 1,218 yuan per metric tonne (mt), or roughly $27/bbl. This policy has fundamentally transformed the economics of China’s fuel oil exports to bonded areas. However, as discussed below, China still needs to import large volumes of bunker fuel because domestic supply remains insufficient to meet demand

MT: With China’s independent refiners (teapots) now producing more compliant low-sulphur fuel oil, what share of China’s bonded bunker demand is now met domestically vs. imported from places like  Malaysia or Russia?

Although independent (“teapot”) refiners cannot export bunker fuels directly as they do not have export quotas, their increased production helps quota-holding national oil companies (NOCs) as well as Zhejiang Petroleum & Chemical Co., Ltd. expand their exports. However, it is worth noting that China’s overall fuel oil production has been declining in recent years because refiners increasingly use deep conversion processes to maximise the production of lighter products and petrochemical feedstocks. In 2025, China exported a record 376,000 b/d of fuel oil, the vast majority of which was shipped to bonded areas. At the same time, China imported 396,000 b/d of fuel oil, primarily from Russia, Malaysia and Singapore, down from the record 514,000 b/d imported in 2024. These imports and exports together form the foundation of China’s bonded-area fuel oil market.

MT: Given China’s push for LNG bunkering and its IMO 2030/2050 decarbonisation targets, how quickly are Chinese ports and shipowners adopting LNG or methanol bunker infrastructure compared to conventional VLSFO?

Indeed, China has made a major push to promote LNG and green methanol as marine bunker fuels, and progress has been steady. However, given the relatively low starting base, their rising impact on VLSFO consumption is expected to be gradual.

MT: How do fluctuations in China’s industrial production and coal imports (via dry bulk carriers) directly correlate with bonded bunker fuel demand at major Chinese ports?

Bonded bunker fuel demand at major Chinese ports is indeed influenced by China’s overall import and export activities. Although China’s coal imports have declined since reaching a record high of 543 million mt in 2024, the country’s total merchandise trade volume has continued to grow year by year. At the same time, China’s GDP growth has slowed compared with a decade ago. In addition, structural changes in trade patterns and shipping routes (such as a decline of exports to the US and a surge of exports to other countries) have also affected bunker fuel demand. A more detailed analysis is needed to determine the precise relationship between trade activity and bonded bunker fuel demand.

MT: What is the typical price spread between Chinese bonded bunker fuel and Singapore’s delivered bunker prices, and how do factors like China’s export quotas or refinery maintenance create arbitrage opportunities?

Following the introduction of the tax rebate policy discussed above, Chinese ports have gained a pricing advantage in the bunker fuel market, as more competitively priced bunker fuel produced domestically has become available. As a result, China’s delivered bunker fuel prices have typically traded at a discount of $15–30/mt to those in Singapore. However, prices fluctuate, and China’s bonded bunker fuel prices are not always lower than Singapore’s for three main reasons. First, China still needs to import large volumes of fuel oil, including VLSFO, into its bonded areas. Consequently, prices in these markets remain closely linked to Singapore’s delivered bunker prices. Second, the volume and timing of export quota allocations to the NOCs play an important role in determining the availability of domestically produced bunker fuel in bonded areas. At times, limited quota availability can tighten supply, resulting in shortages at China’s bonded ports. Third, during periods of geopolitical or market disruption, such as the Iran conflict since February 2026, market fundamentals can change rapidly, leading to heightened price volatility.  The bottom line is that, regardless of the absolute price spread between China and Singapore, fluctuations in the spread and China’s need to import bunker fuels continue to create arbitrage opportunities for traders.

MT: Anti-dumping duties and policies introduced by the European Commission and western regulators have resulted in overcapacity of UCOME in China; given the material cannot obtain ISCC EU certification to be blended as bio-bunker fuel (i.e. EU ETS, carbon credits), what will be your advice to Chinese holders of excess UCOME?

Like many other renewable energy products (such as solar panels) and electric vehicles, China’s UCOME industry has expanded rapidly and now faces growing trade barriers in Western markets because of its strong export growth. While there are no easy solutions for producers with excess capacity, several strategies could help.  First, producers should continue improving efficiency and reducing costs to remain competitive despite the import duties and other trade measures imposed by the EU and some other developed economies. Second, they should diversify export markets beyond the EU by targeting emerging opportunities in advanced economies such as Singapore. In particular, Singapore could leverage China’s surplus UCOME supply to accelerate the development of its sustainable aviation fuel (SAF) and bio-bunkering industries. Finally, China’s UCOME industry could encourage the Chinese government to expand domestic blending mandates, including greater use of SAF and bio-bunkering fuels, to stimulate domestic demand and help absorb excess production.

Dr Wu will be leading a two-day executive briefing, China Oil Market Dynamics, held on 26 to 27 October in Singapore. The intensive briefing will provide a comprehensive outlook on China’s oil market through 2035, covering the key market, policy, economic and structural forces shaping its future.
