The number of ships with batteries is increasing and it is exciting to see the movement in the maritime battery market. Since 2016 Maritime Battery Forum has been keeping track of battery installations in shipping. Its Ship Register has been the go to source for this information. Battery statistics are primarily compiled from project information received directly from battery suppliers and system integrators. This presentation will provide some fascinating analysis on the last 8 years of progress.

In this presentation Maria Strandesen who led Maersk's five-year research on identifying the optimal fuel mix for decarbonizing their fleet of 700+ ships will set out her perspective on progress in the industry.

The ferry sector has significantly improved in reducing emissions and enhancing sustainability. This presentation will review critical milestones, benefits, and challenges of electrification, including case studies of successful implementations. Finally, we will explore emerging technologies and the importance of collaboration to achieve a sustainable and decarbonised future for ferries.

The electrification of passenger ships, both cruise and ferries, is becoming increasingly popular as a measure to comply with stringent environmental regulations and improve operational reliability and efficiency, especially for hybrid ships with conventional engines and battery installations. Modern battery technology enables even larger ships or those on longer routes to operate solely on electric propulsion. However, the lifecycle and disposal of these batteries must be considered. Various options exist for recharging, including conventional engines or port-based charging systems, as well as battery swapping. The presentation will explore the pros and cons of battery installations from sustainability and operational perspectives in a concise manner.

This presentation will review the various options which operators can adopt in the drive to decarbonize. Focusing on the pathways specifically for short sea cargo vessels, the presentation will provide a valuable perspective on how to assess alternative fuel and machinery options as well as scenarios, in order to select optimum solutions.

Among the renewable fuels, methanol is particularly well suited for marine propulsion systems as it is easier to handle in terms of fuel storage, global availability, safety requirements, retrofit solutions and emissions compared to other sustainable fuels. The objective of this presentation is to provide an overview of the use of methanol as a fuel for internal combustion engines in marine propulsion systems, with a focus on the advantages and disadvantages of the methanol combustion process. This will be achieved by comparing two different diesel-methanol combustion concepts with a state-of-the-art diesel engine. In addition, the efficiency chain of the methanol production and the requirements for the exhaust gas aftertreatment system will be discussed.

The EU-supported Apollo project, a consortium of eight European companies and institutions, will install a dual-fuel engine, able to operate on ammonia, in the Viking Energy, a platform supply vessel owned and operated by Eidesvik Offshore. Viking Energy is also a demonstrator vessel in the EU-funded ShipFC project, which aims to pilot ammonia-powered fuel cells. This presentation will look closely at the project and at ammonia as an alternative fuel.

This presentation outlines several strategies to establish supply chains for liquid hydrogen as a zero-emission fuel for the maritime industry. It looks at a number of hydrogen production and sourcing scenarios, bunkering possibilities and use cases in shipping.

Nuclear energy has the potential to become a main alternative allowing sustainable marine shipping and reducing greenhouse gas emissions. This study defines a power generation arrangement and evaluates design speed for nuclear-powered vessels. Higher design speeds show promising economic results. This includes higher revenue and trade while maintaining relatively low operational expenditures when compared with conventionally powered ships. It will summarize what boundary conditions will have to be created or confirmed to realize the next steps of implementation.

A model based rightsizing analysis for a battery & fuel cell hybrid vessel by FEPS. The study highlights how an energy conversion and storage system on board a yacht can be designed to cover a typical load profile. Real life power data was used to design the hybrid system setup as well as the operational mechanisms to operate both systems in the most efficient way
