Q&A: Bio-bunkers pivotal to low-carbon transition

Equatorial Marine Fuel (EMF) is a leading Singapore-based physical supplier of marine fuels. The company has an existing fleet of 21 vessels and bunkers conventional fuels as well as emerging green fuels, like B24 and B30 blends.

EMF was the largest volume supplier of marine fuels at the port in 2023, according to the Maritime and Port Authority of Singapore (MPA). The company is expanding its footprint into supplying green marine fuels and is supplying biofuel blends.

Argus' Mahua Mitra spoke with the company's chief operating officer Choong Sheen Mao about the potential and challenges lying ahead for marine biodiesel and other emerging fuels.

What is EMF's strategic position on bio-bunker fuels within Singapore's marine fuel mix?

Equatorial believes that bio-bunkers will continue to play a pivotal role in the maritime industry's transition towards low- and zero-carbon marine fuels. In the near-term, biofuels are the most price-competitive low-carbon marine fuel. In the mid- to long-term, however, it remains to be seen whether biofuels' comparative ability to scale coupled with the diversion of supply to other industries will cause biofuels to be less competitive. Equatorial is focused on the now.

Our volume and variety of biofuel bunker deliveries have increased. We have been looking at this space closely over the past few years, having obtained our International Sustainability and Carbon Certification (ISCC) in 2022 and performed our first biofuel delivery in 2023. We continue to monitor and participate in the development of other alternative marine fuels as well.

Given the regulatory requirements around biofuel delivery, what is your assessment of Type II barge availability in Singapore?

Conventional bunker tankers operating in the Port of Singapore have been allowed to carry and deliver biofuels up to B30 since 7 March 2025. While there will be more Type II barges available in Singapore, this may not have a material impact on biofuel deliveries in the near term as most deliveries are still either B24 or B30.

In any event, Equatorial has invested in four 7,999 deadweight tonne (dwt) IMO Type II chemical and oil bunker tankers capable of carrying and delivering methanol and biofuels up to B100. Two of these Type II barges have been delivered at the start of this year, and we are looking at two more to be delivered in the third or fourth quarter of 2025. Equatorial is in a position to actively participate in supplies of biofuels up to B100.

Which types of biofuel blends (e.g., B24, B30) are you seeing increased demand for in the near term? What market, regulatory, or operational factors are shaping these preferences among your clients?

The considerations regarding the use of alternative marine fuels depends on a myriad of factors including but not limited to the vessel's trading area, business model, and end-customer/consumer base. The increasing demand of B24 and B30 bio-fuel blends fluctuate between these regulatory and commercial concerns. The GHG Fuel Intensity (GFI) framework, in combination with a pricing and reward mechanism that was recently approved by the International Maritime Organisation's (IMO) Marine Environment Protection Committee (MEPC) during its 83rd session (MEPC 83) in April 2025, will be the single most significant consideration for our clients.

If formally adopted in October 2025, it will be mandatory for large ocean-going ships over 5,000 gross tonnage, which emits 85pc of the total CO2 emissions from international shipping. It would then enter into force in 2027. For vessels trading with the EU, they would already be familiar with the European Union (EU) Emissions Trading System (ETS) on carbon allowances and FuelEU Maritime penalties.

Is EMF considering entry into the LNG bunkering segment, either directly or through strategic collaboration?

Equatorial has ordered a 20,000m³ LNG bunkering vessel to be delivered in 2027. With the global demand for LNG as a marine fuel projected to increase substantially over the next few years, Singapore, the world's largest bunkering hub, is a strategic location for LNG bunkering.

The key concern is how soon existing bunkering infrastructure should be further scaled to meet the increase in demand.

When it comes to bio-blend trading, what are the most significant challenges you anticipate?

Presently, the most significant challenges are still demand and price-competitiveness. Lower oil prices would mean biofuel feedstocks are relatively expensive. These are uncertain times, nonetheless, and geopolitical development remains highly uncertain, and, as such, commodity prices highly volatile. Bunker buyers will always opt for the most economical means to comply with regulations and requirements. Equatorial continues to manage business risk by working closely with customers on their requirements and closely monitoring international affairs and markets.
