Practical Approach Towards Green Methanol as Maritime Propellant
Abstract Maritime transport plays an essential role in the EU economy and is one of the most energy-efficient modes of transport. Nevertheless, it is as well a large and growing source of greenhouse gas emissions. Consequently, the use of alternative carbon-neutral propellants in shipping must be investigated and promoted.
