Advancements in Marine Propulsion Technologies

The global shipping industry alone emits approximately 1000 million tones of (CO2) annually according to the International Maritime Organization (IMO) and the European Commission. This level is expected to increase by approximately 50% to 250% by the year 2050. IMO has been framing policies and developing capacity building programs to reduce the emission from the shipping industry. IMO has successfully launched regulations aimed at the reduction of nitrogen oxides and sulfur oxides. Significant progress also has been made in implementing them and achieving the reduction process. With the introduction of the maritime regulations which call for a reduction in the emissions from the ships and vessels and the developments in sectors like energy storage and clean energy, the adoption of cleaner propulsion options onboard becomes inevitable.

This study focuses on the electrical equipment aiding the vessels to shift to electric propulsion, alternate energy options for vessel operation and propulsion systems operation like fuel cell, battery energy storage and their current stages of adoption.

Companies are involved in developing electric and hybrid propulsion solutions for the vessel. Developments in energy storage which enable high power and energy output enable their usage in both power and propulsion applications. It covers global best practices case studies about the vessels which have already started adopting such solutions and the developments in the fuel cells that makes them suitable for marine applications.
