The Global Maritime Forum, Global Centre for MaritimeDecarbonisation (GCMD), the Mærsk Mc- Kinney Møller Center for Zero Carbon Shipping conducted a survey of 29 shipping companies to understand how industry leaders are thinking about future fuels and their plans to adopt cleaner fuels and efficiency-boosting technologies, according to GCMD on Thursday (20 April). 

The companies surveyed roughly represent 20% of the world’s total fleet capacity; they own and operate container ships, tankers, dry bulkers, gas carriers, car carriers, cruise ships, tugs, and offshore vessels.

Respondents, professionals responsible for the decarbonisation efforts of these organisations, were asked about their plans and projections to adopt cleaner fuels and efficiency boosting technologies.

“As the shipping industry is in a period of experimentation and exploration to understand the implications of adopting different green fuels, surveys like this play a crucial role to inform the industry and public, and support shipping’s transition to a zero-emissions future,’’ Professor Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation said. 

The most striking result from the survey is a multi-fuel future: the need to prepare for fleets operating on three or more fuel ’’families.’’ The most common mix by 2050 represented by 40% of respondents is a fleet concurrently running vessels on fuel oil/biodiesel, methane, methanol, and ammonia—a step-change in fuel diversity.

Bo Cerup-Simonsen, CEO of the Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping, said, “the industry will need to think strategically about how to operate multi-fuel fleets and green fuels must be introduced in a safe and cost-efficient manner to make them the preferred alternative to current petroleum products.’’

Other findings from the survey suggest that internal combustion engines will remain the preferred technology through 2050, and that the speed of shipping industry’s adoption of alternative fuels will be a function of the cost gap with fossil fuels and the degree of availability of such greener alternatives at ports worldwide.

Ports and bunker suppliers might prioritise the availability of individual fuels in the short term. But in the longer-term, ports that wish to attract the greatest possible number of future vessels should prepare for the need to offer multiple fuel types.

The single most important factor in fuel choice will likely be the rate of decarbonisation required by regulators. Policymakers and regulators can help close the cost gap between green fuels and fossil fuels and create a “level playing field” for all shipping companies to accelerate their adoption of green fuels.

’’To reach zero-emissions by 2050, the industry needs a more ambitious regulatory framework with clear reduction targets and supporting policies to close the cost gap between green fuels and the fossil fuels that current power the global fleet. The sooner there is clarity about targets and policies, and the sooner these come into effect, the easier it will be for companies to develop a view on how to meet the goals. The role of regulators will be crucial in this process, in particular the outcome of the ongoing negotiations at the IMO,” Johannah Christensen, CEO of the Global Maritime Forum, said.

“The survey paints a multi-fuel picture of the industry that is striking. The onus is on each shipping company to develop its own proprietary view of its future fuel mix in line with its business strategy and decarbonisation ambitions,’’ the trio said.

The survey was conducted with analytical support by McKinsey & Company.

EDF, LR and Arup launch tool scoring ports’ potential to produce and bunker electrofuels

Lloyd’s Register (LR) Maritime Decarbonisation Hub and Environmental Defense Fund (EDF), in collaboration with Arup, on Tuesday (28 November) introduced the Sustainable First Movers Initiative Identification Tool, a system to help shipping stakeholders align investment decisions that support the maritime energy transition away from fossil fuels.

The tool, which is presented in a preliminary findings report – The Potential of Ports in Developing Sustainable First Movers Initiatives – scores a port’s potential to produce and bunker electrofuels while delivering local environmental and community benefits in alignment with the global temperature target of 1.5 degrees Celsius set by the Paris Agreement.

“Ports can play an important role in kickstarting shipping’s decarbonisation process even before global policies are established,” said Marie Cabbia Hubatova, Director, Global Shipping at Environmental Defense Fund.

“By considering the impact sustainable first mover initiatives can have on port-side communities, climate, environment and economies, resources can be better directed to locations where these initiatives will make the biggest difference.”

With close to two billion people living near coastal zones globally, the role of, and impacts on local port communities must be intentionally considered as the sector decarbonises globally. Ports can play a crucial role in ensuring shipping decarbonisation efforts are done in a way that has positive impacts on port communities.

The preliminary phase of the Sustainable First Movers Initiative Identification Tool analyses 108 ports in the Indo-Pacific region according to five criteria including land suitability, air quality, renewable energy surplus, economic resilience and ship traffic.

It is also applied to three different port scenarios, including ports exploring fuel production and bunkering, ports exploring fuel exports, and ports exploring fuel imports and bunkering. The combined criteria and scenario evaluation determines which ports have the greatest potential (high potential) for sustainable first mover initiatives to lead to significant emissions reductions and positive impacts in nearby communities, such as improved air quality and economic resilience.

“The transition to clean energy supply for shipping can be achieved only if stakeholders act together. Identifying potential port locations is the first step in this process,” said Dr Carlo Raucci, Consultant at Lloyd’s Register Maritime Decarbonisation Hub. “This approach sets the base for a regional sustainable transition that considers the impacts on port-side communities and the need to avoid regions in the Global South lagging behind.”

Regions in the Global South are fundamental in driving the decarbonisation of shipping. To make this transition effective, the rate at which different countries adopt and scale up electrofuels must be proportional to the difference in capital resources globally to avoid additional costs being passed on to local communities. Sustainable first mover initiatives can play an important role in making this happen by ensuring the sector’s decarbonisation is inclusive of all regions and by engaging all shipping stakeholders, including port-side communities.

“There’s a huge opportunity for early adopter shipping decarbonisation initiatives to unlock benefits for people and planet – shaping the way for a more equitable transition in the 2030s,” said Mark Button, Associate, Arup. “Our collective approach shows that taking a holistic view of shipping traffic, fuel production potential and port communities could help prioritise action at ports with the greatest near-term potential.”

The tool can be customised according to stakeholders’ needs and goals and is dependent on scenario desirability. The next phase of this work will include the selection and detailed assessment of 10 ports to help better understand local needs and maximise the value offered by sustainable first mover initiatives. 

LR and EDF carried out a joint study on ammonia as shipping fuel, and LR and Arup have collaborated on The Resilience Shift study focused on fuel demand for early adopters in green corridors, ports, and energy systems, amongst many other projects.

Wärtsilä signs agreement for first zero-emission high speed ferries in US

Technology group Wärtsilä on Tuesday (28 November) said it has signed a strategic partnership agreement to provide its Fleet Electrification and Systems Integrator Services for a project to build the first zero-emission high speed ferries in the United States.

The fully electric vessels will be built for San Francisco’s Water Emergency Transportation Authority (WETA), the operator of the San Francisco Bay Ferry system.

The project, and several others Wärtsilä will work on under this partnership, are a part of the agency’s Rapid Electric Emission-Free (REEF) Ferry Program, a phased decarbonisation of high-speed, high-capacity ferry service in the San Francisco Bay. 

Wärtsilä will work within the WETA project team to finalise vessel and charging system concepts.

“We’re proud to operate the cleanest high-speed ferry fleet in the nation, but a zero-emission future for our system is within reach,” said WETA Executive Director, Seamus Murphy. 

“Wärtsilä’s expertise and experience will be incredibly valuable given the complexity our ferry decarbonisation program entails.”

“This is a major project within the maritime sector’s journey towards decarbonisation, and we are proud to be a part of it,” said Hanno Schoonman, Director of sales for AMER region, Wärtsilä Marine Power. 

“Wärtsilä joins an industry leading team tasked to develop newbuild battery electric vessels that combine innovative technology and sustainable practices. Wärtsilä is well qualified to provide this project support, and this agreement is a clear endorsement of our strong track record in systems integration and emission-free propulsion.”

After completing the conceptual phase, WETA will move on to the initial construction phase of a multi-vessel programme. This phase will involve the building of three smaller ferries with a capacity of approximately 150 passengers each and two larger ferries capable of carrying at least 300 passengers. 

Additionally, the scope of this phase will encompass the inclusion of battery charging floats. The construction of the first electric-powered vessel is slated to commence before the conclusion of 2023, with commercial operations expected to launch in 2025.
