This report provides a comprehensive guide to shipowners, operators, ship designers, and shipyards on designing and planning a successful methanol retrofit, underscoring the main technical considerations while complying with regulatory requirements.

This set of reports seeks to enable stakeholders across the maritime industry to pursue a green transition that puts safety at its core.

This report explores which ports are best positioned to be first movers in bunkering alternative fuels and how ports can position themselves advantageously in the transition.

The Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping (MMMCZCS) has developed this publication to shed light on the ship design best practices that will support the development of ammonia-fueled ship designs.

The Center has undertaken a survey of over 2,000 respondents across the maritime community to better understand their perceptions, concerns, and requests relating to ammonia as a marine fuel.

Transitioning the world fleet to climate-friendly alternative fuels is essential for decarbonization of the shipping industry. However, vessels being built or ordered today will likely be operating for decades to come, and many alternative fuels are not yet available at scale.

Biogenic CO₂ provides one of the most straightforward and least costly such feedstocks. Therefore, the industry needs to understand how much biogenic CO₂ is available globally, as well as where and at what cost. In addition, we need to understand the opportunities and barriers for shipping to access this feedstock.

While the tank-to-wake (TTW) carbon dioxide (CO₂) emissions from the complete combustion of methane are nearly 30% lower than those from diesel for the same energy, methane slip emissions during combustion and fuel production may pose an obstacle for methane-based pathways to reach zero emissions. To make methane-based fuel pathways viable solution for net-zero shipping, methane emissions during the whole life cycle need to be addressed.

Successful decarbonization of the shipping industry will depend on the maturation and adoption of a range of alternative maritime fuels. To support this goal, this series of reports presents a deep dive into the potential of biogas as a source of biofuels for shipping.

While alternative fuels for shipping are a major area of research and development, this report puts the spotlight on fuel cells as an alternative fuel conversion technology of potential interest to the shipping industry.

The FuelEU regulation comes into effect on 1 January 2025. This regulation will be an industry game changer as it requires all vessels calling at European Union (EU) ports to decrease the emissions intensity of fuels, thereby leading to an increase in the use of alternative fuels over time.
