Canadian vessel operators are fortunate to have access to fuels and energy produced from renewable sources such as wind and hydro, now or in the future. This is essentially the port of the future. To seize these opportunities and optimize ship’s energy and operational efficiencies, we need to develop power and propulsion technologies for integration into practical vessel applications. Additionally, vessel owners need to build new vessels now that can leverage these innovative & emerging technologies over 40+ year lifespans. In our endeavour to support decarbonization of the shipping industry, we will discuss the challenges faced with the production methodologies of alternative fuels including the types of fuels that can be generated from renewable energy. We will discuss how these fuels are integrated in vessel operations and how technologies for engines and other energy converters can be utilized for these fuels, including current technology readiness levels. We will also evaluate how fuels can be stored and manipulated onboard to produce clean burning derivative fuels at the point of use, with supporting carbon capture technologies. Part of the discussion will revolve around how various engines, fuel types, energy storage, energy saving devices and fuel cells are integrated into vessel propulsion solutions. Additionally, we will consider the challenges and opportunities for use of electricity from shore as energy in the vessel, and show some examples of how some of these different technologies have already been implemented. Finally, we will consider the conundrum that vessel owners face; how to reduce their carbon footprint of global shipping. How to design and build vessels that are essentially future proofed through their lifecycle. Through all topics we will consider the carbon intensity of the various fuels from production of the fuel to producing thrust at the propeller (“well to wake”).
