NABU study shows methanol as bunker fuel can make ocean shipping more climate-friendly

Methanol can offer sufficient energy density for most voyages and is comparatively easy to handle; E-Methanol can potentially enable a well-to-wake climate-neutral operation of a ship.

A new study carried out by the Öko-Institut, on behalf of German environmental association NABU, has concluded that methanol as a marine fuel and energy carrier bears low environmental risks compared to other potential bunker fuels.

According to a summary of the study titled Methanol as marine fuel, methanol can offer sufficient energy density for most voyages and is comparatively easy to handle. 

“E-Methanol enables a well-to-wake climate-neutral operation of a ship if produced using renewable energy and if CO2 is sourced from the atmosphere,” it said. 

The main obstacle tends to be the huge amount of renewable energy necessary for production. The biggest chance to overcome this is straight forward regulation that increases demand, provides planning security for first movers and investors, and puts a price tag on greenhouse gas (GHG) emissions. If used in combustion engine air pollutant emissions from methanol must be reduced by proven technical measures.

Upscaling the production and supply of RNFBO (Renewable Fuels of Non-Biological Origin) is crucial to decarbonise maritime transport. So far, there is little experience using hydrogen, e-methanol or e-ammonia as a fuel in shipping. It is further not yet clear which fuel is the most appropriate for use in deep-sea shipping and which option will gain the highest share in the future fuel mix.

The study investigated whether the potential benefits and risks of e-methanol are sufficiently reflected in the current discussion about future marine fuels and whether methanol is preferable to current fossil marine fuels and other RFNBOs. 

Policy recommendations

Today methanol is primarily produced from natural gas and is not able to provide GHG savings compared to conventional fossil fuels like diesel, heavy fuel oil or LNG. Thus, all regulations must be targeted to green e-methanol but not neglect air pollutant reduction, especially nitrogen oxide. 

Moreover, formaldehyde emission prevention has to be incorporated in further development. Green hydrogen production and the DAC technology need to be scaled up significantly to provide substantial amounts of green methanol for shipping. Policy makers therefore should implement straight forward regulation as soon as possible.

These could include GHG reduction targets, a price tag on GHG emissions, green fuel quotas, and mechanisms to encourage the use of methanol, such as through accounting and reporting mechanisms. Regional regulation and infrastructure improvements can also help promote the adoption of RFNBOs.

Also support for investments in environmentally friendly methanol production facilities, early adaptation of land use planning and infrastructure at ports, or the use of CCfDs (Carbon Contracts for Difference) are key instruments to ramp up the supply. At the same time, the demand side should be supported by the European Union and the World Shipping Organization (IMO), which have to set decisive levers for more climate friendly shipping.

Burando Energies delivers B30 bio bunker fuel to tug “MV Bylgia” in Rotterdam

Burando Energies on Thursday (16 January) announced it successfully delivered ISCC-certified biofuel to Heerema’s Anchor Handling Tug MV Bylgia at the Port of Rotterdam.

The delivered B30 biofuel blend, derived from renewable feedstocks, will help reduce carbon emissions by an estimated 25% (well-to-wake)—an impactful move in Heerema’s ongoing commitment to sustainability.

“This delivery not only reflects our commitment to offering sustainable energy solutions but also strengthens our partnership with Heerema in their green ambitions,” said Duncan Huisman, Sustainable Bunker Trader at Burando Energies. 

“We are proud to contribute to initiatives that prioritise the well-being of our planet and future generations.”

Burando Energies said it will continue to focus on innovation and sustainability, striving to provide energy solutions that drive both environmental progress and business success.

DNV whitepaper: Limited supply could hamper future uptake of bio bunker fuel

Long-term future of the maritime biofuel market hinges on the availability of sustainable biomass at an affordable level, as well as competition with other sectors, says Knut Ørbeck-Nilssen, CEO Maritime.

Key biofuels like FAME and HVO have great potential for reducing greenhouse gas (GHG) emissions and supporting compliance with maritime regulations, but their benefits to the industry could be constrained by limited supply in the future, according to DNV’s latest white paper Biofuels in Shipping, published on Thursday (16 January). 

Knut Ørbeck-Nilssen, CEO Maritime at DNV, said: “Biofuels present a promising decarbonization option for shipowners, and it's encouraging to see steady growth in the number of bunkering ports offering biofuels in recent years.”

“However, the long-term future of the maritime biofuel market hinges on the availability of sustainable biomass at an affordable level, as well as competition with other sectors.”

“Shipowners should, therefore, aim to explore energy efficiency measures and alternative fuels as part of their wider decarbonization strategies, while utilizing biofuels where they are available and affordable.”

In 2023, the maritime sector consumed just 0.7 million tonnes of oil equivalent (Mtoe) of liquid biofuels, representing a mere 0.6% of global liquid biofuel supply and 0.3% of shipping’s total energy use, highlighting the limited uptake of biofuels in shipping today compared to other sectors. 

Despite this, biofuel holds significant potential for reducing GHG emissions and achieving compliance with regulatory frameworks, such as CII, EU ETS, and FuelEU Maritime. To realise these benefits, the biofuels used must meet stringent sustainability and GHG savings requirements, verified through a Proof of Sustainability (PoS) or similar document.

Drawing on in-depth interviews and written surveys of eight biofuel suppliers and 12 shipping companies, the paper identified more than 60 locations which have already been proven to have carried out biofuel bunkering operations since 2015. The report estimates that the ports of Singapore and Rotterdam accounted for about half of all biofuels supply to shipping in 2023.

The majority of biofuel consumption in shipping occurs through fuel blends, combining biofuels like FAME and HVO, the most established biofuels for maritime use, with conventional oil-based fuels. 

The DNV white paper contains an overview of the main technical and operational considerations for use of biofuel as a ‘drop-in’ fuel. This includes key recommendations to shipowners such as verifying fuel quality, compatibility with onboard systems, and monitoring performance.

Øyvind Sekkesæter, Consultant in Maritime Environmental Technology at DNV and Lead Author of Biofuels in Shipping, said: “The technical compatibility of key marine biofuels like FAME and HVO varies from ship to ship, making it essential to assess each case individually.”

“Doing so will ensure that the fuel specification and quality are compatible with their intended application, minimizing the risk of damage to equipment and loss of power onboard the vessel.”
