Marine transportation alone contributes roughly 2.2% of global greenhouse gas emissions (GHG). Although shipping produces significantly less CO2 emissions per ton-km of transported goods than other means of transportation, incentives have been made in order to further reduce the impact of this sector on global warming. The objective of this project is to assess the performance, emissions and market potential of combustion concepts for marine engine applications that rely entirely on renewable fuels.
At the Institute of Chemical Engineering and Environmental Technology a study on the quality and production capacities of renewable fuels for marine transportation is carried out. It summarizes current challenges and bottlenecks in the respective processes and highlights their potential and future needs for research. The study gives information on fuel qualities and production capacities depending on the underlying production process. It compares the resource and energy demand in the production process and evaluates fuel output compared to primary energy use.
