An International Council on Clean Transportation (ICCT) report published on Wednesday (14 September) investigated several assumptions regarding liquefied natural gas (LNG) to help mitigate climate impacts of the maritime shipping sector. 

The report titled Comparing the future demand for, supply of, and life-cycle emissions from bio, synthetic and fossil LNG marine fuels in the European Union was written by authors Bryan Comer, PhD, Jane O’Malley, Liudmila Osipova, PhD, and Nikita Pavlenko. 

The report focused on ships trading with the European Union. It predicted a tripling of demand for LNG as marine fuel between 2019 and 2030, based on trends in fuel consumption. 

It also estimated that renewable LNG will cost seven times more than fossil LNG in 2030 and, therefore, subsidies or other policies would be needed to encourage its use.

The study said the idea that LNG can help mitigate the climate impacts of the maritime shipping sector rests on the assumptions that ships can switch to bio and e-LNG (renewable LNG) in the future and that switching would result in low greenhouse gas (GHG) emissions. 

However, for this to happen, there must be enough renewable LNG to meet future demand and using it must result in a substantial reduction in GHG emissions on a life-cycle basis compared to fossil LNG. 

“Understanding whether these assumptions are realistic is important for policymakers, including in the European Union, which has committed to reducing its GHG emissions by at least 55% below 1990 levels by 2030 (that is equivalent to a 41% reduction from 2019 levels),” it said. 

The well-to-wake (WTW) carbon dioxide equivalent (CO2e) emissions associated with three 2030 scenarios in the European Union are shown in the figure below. Compare the scenario in which ships use 100% renewable LNG in 2030 (far right, representing a €50 per gigajoule subsidy) to emissions from using 100% fossil in 2019 (far left). 

ICCT: Methane slip must be eliminated for renewable LNG bunker fuel to be a feasible solution for shipping

As shown, using renewable LNG could cut WTW CO2e emissions by 38% based on 100-year global warming potentials (GWP, labeled as CO2e100) but raise emissions 6% based on 20-year GWP (CO2e20) because of methane’s strong near-term warming effects. Focusing on the orange portions of the bars, even using 100% renewable LNG doubles methane emissions compared to 2019; this is primarily because of methane slip from marine engines.

According to the report, for renewable LNG to significantly contribute to achieving climate goals, methane slip from marine engines needs to be virtually eliminated and methane leaks upstream need to be greatly reduced. 

According to the report, methane slip from marine engines needs to be virtually eliminated and methane leaks upstream need to be greatly reduced for renewable LNG to significantly contribute to achieving climate goals. 

“Additionally, methane leaks from onboard fuel tanks and cargo tanks, which researchers are still working to adequately quantify, would need to be near zero. It is important for policymakers and stakeholders to understand that other fuels, including synthetic diesel and green methanol, could offer low life-cycle emissions without the methane problem,” it said.

China Shipping & Sinopec Suppliers completes first biofuel bunkering op of passenger ship in Dalian

China Shipping & Sinopec Suppliers Co., Ltd. on Wednesday (29 November) successfully refuelled passenger ship "Chang Shan Dao" owned by Cosco Shipping Ferry Co., Ltd. with B24 bio bunker fuel at the Dalian Cruise Port. 

The occasion marked the first biofuel bunkering operation for passenger ships in China. 

The B24 biofuel oil used was blended with 24% biofuel and 76% conventional low-sulphur fuel oil.

Sinopec China Shipping Fuel Supply, which is responsible for the bunkering operation, is a bunker supply firm jointly established by Sinopec Group and COSCO Shipping Group.

According to Li Zhi, Deputy Party Secretary and Deputy General Manager of China Shipping & Sinopec Suppliers Co., Ltd., the biofuel bunkering business is another step in the company's active business of the group's development strategy. 

The bunkering operation after the firm completed the first bonded biofuel bunkering operation of a domestic ship on 7 September.

Singapore, Tianjin to pilot and trial alternative bunker fuels following shipping corridor MoU

The Maritime and Port Authority of Singapore (MPA) and the People’s Republic of China’s Tianjin Municipal Transportation Commission on Wednesday (6 December) signed a memorandum of understanding (MoU) to establish the Singapore – Tianjin Green and Digital Shipping Corridor.

Mr Teo Eng Dih, Chief Executive, MPA, and Mr Wang Zhinan, Director General, Tianjin Municipal Transportation Commission, signed this MoU.

The MoU marked the first Green and Digital Shipping Corridor established between Singapore and China to support the decarbonisation, digitalisation and growth of the maritime industry between Singapore and the Bohai Region. 

The Singapore – Tianjin Green and Digital Shipping Corridor will serve as a valuable testbed for both countries to pilot and trial digital solutions, alternative bunker fuels and technologies, and facilitate talent development to support the decarbonisation and digitalisation of shipping. 

Singapore and Tianjin will work with the research community, the  institutes of higher learning, and industry stakeholders such as shipping lines, port operators, shipbuilders, classification societies, and bunker suppliers to enable more efficient port clearance through digital exchanges, encourage the offtake of zero or near-zero greenhouse gas emission fuels and adoption of new fuel technologies, spur innovation and support the growth of the maritime startups community, and facilitate manpower training and professional development.

The establishment of the Singapore – Tianjin Green and Digital Shipping Corridor reaffirms the strong commitment by Singapore and Tianjin to accelerate maritime decarbonisation and digitalisation. Singapore will also be exploring the establishment of similar collaboration with other maritime and port ecosystems within China.

Report highlights routes-based action plan methodology to accelerate uptake of clean bunker fuels

The Maritime and Port Authority of Singapore (MPA) on Thursday (7 December) said the NextGEN Connect-Green Voyage2050 Project identified a key role for regional hubs to help connect large demand clusters and remote locations, with regional fuel supply sources, in order to enable a more inclusive and effective transition to a low-carbon maritime future. 

The project is a collaboration between Singapore, Norway and the International Maritime Organization (IMO). 

These findings were unveiled in the Lloyd’s Register Maritime Decarbonisation Hub (LR MDH) report titled Routes-based Action Plans: A Toolkit launched at the Voyage to Net-Zero Forum, which was organised by MPA, at the 28th United Nations Climate Change Conference (COP28/CMP8/CMA5) yesterday.  

The report was developed following a workshop discussion that was held from 5 to 6 October 2023 in Singapore, with the participation of 40 stakeholders representing ports and National Administrations across Asia, based on the concept of the LR MDH’s First Movers Framework for green corridors. The workshop simulated the process steps of the routes-based action plan methodology, addressing the limitations in its application in the wider Asian context. Additional engagements with stakeholders from the Pacific are envisaged to further refine the methodology. 

“One of the key findings in our report highlighted the varying pace of decarbonisation efforts across the Asian region and the need for regional coordination among governments to establish energy clusters that will serve both as demand centres and energy producing hubs” said Charles Haskell, Director at LR MDH. 

The creation of energy producing hubs includes defining a strategy that brings together demand from different countries at different developmental stages across the region to build up investment cases for implementing energy infrastructure at scale, all the while taking into consideration the economic and social benefits for local communities. 

The report also emphasised that routes-based action plans should be steered by national governments to give confidence to the industry’s infrastructure investment decisions, with development banks and regional funds needing to play a part to help tailor financing solutions to support infrastructure development. 

“If we truly want to achieve a net-zero future where no one is left behind, we cannot focus only on existing first mover initiatives. We must also study locations where the energy infrastructure is still in its infancy”, added Charles Haskell. 

Essential to driving the implementation of routes-based action plans, as highlighted in the report, is the pooling of resources and capacity building to develop the business case for building the necessary infrastructure for regional hubs that include Least Developed Countries (LDCs) and Small Island Developing States (SIDS). This will require regional coordination and collaboration involving governments and all stakeholders across the maritime supply chain.

Mr. Teo Eng Dih, Chief Executive of MPA, said: “As we steer toward a sustainable maritime future, fostering a collective and inclusive approach is imperative in the development of green corridors and the energy transition to decarbonise international shipping.”

“The NextGEN Connect-GreenVoyage2050 collaboration emphasises the important role of regional energy hubs in enabling the inclusive adoption of clean marine fuels, particularly for LDCs and SIDSs. MPA looks forward to continuing its collaboration with IMO, Ministry of Climate and Environment of Norway and LR MDH to pilot solutions to reduce GHG emissions from ships and drive innovative transformations in the maritime industry.”

Sveinung Oftedal, Chief Negotiator of the Norwegian Ministry of Climate and Environment, said: “Separate routes for emission-free ferries and ships can play an essential role in stimulating early action to adopt zero or near-zero emission technologies and fuels, and hence are an important step towards decarbonising shipping. There is currently a significant volume of maritime traffic between Asian countries, and our workshop was a great forum to discuss opportunities the decarbonisation of maritime shipping can bring and how efforts can be linked to countries’ wider energy transition.”

Jose Matheickal, IMO Director of Partnerships and Projects, said: “Supporting developing countries, including SIDS and LDCs, in their efforts to implement the 2023 IMO Strategy on the Reduction of GHG Emissions from Ships is imperative to the decarbonisation of the maritime sector. IMO is pleased to provide, through this collaboration, practical support around the development and subsequent implementation of National Action Plans and route-based actions in line with IMO’s MEPC RESOLUTION.366(79) that encourages Member States to undertake these voluntary actions to facilitate the achievement of greener shipping and reduced emissions.”
