Performance optimisation of solid oxide fuel cells through waste heat recovery systems for marine applications
Performance optimisation of solid oxide fuel cells through waste heat recovery systems for marine applications
With the ever-increasing demand for emission reductions within the maritime industry, a global effort is being made to decrease the carbon footprint of vessels. This study investigates the introduction of 10.5 MW SOFC, as an integral component of a 6000-passenger cruise vessel’s powertrain, to provide and cover the total energy demand on board whilst in port and the ‘hotel load’ during voyages. Furthermore, effective ways of utilizing the otherwise wasted heat from the exhaust are investigated, to increase the powertrain system’s overall efficiency and subsequently decrease its carbon footprint, through the utilization of a Waste Heat Recovery System. Results showed 7,078 tonnes reduction of LNG fuel consumption and 31,919 tCO2e emission savings annually when running the SOFCs on LNG, with the recoverable waste heat from the SOFCs being less than from the current LNG generator sets, requiring additional boiler power to meet a 4 GWh of annual heat deficit.

Abstract
With the ever-increasing demand for emission reductions within the maritime industry, a global effort is being made to decrease the carbon footprint of vessels. This study investigates the introduction of 10.5 MW SOFC, as an integral component of a 6000-passenger cruise vessel’s powertrain, to provide and cover the total energy demand on board whilst in port and the ‘hotel load’ during voyages. Furthermore, effective ways of utilizing the otherwise wasted heat from the exhaust are investigated, to increase the powertrain system’s overall efficiency and subsequently decrease its carbon footprint, through the utilization of a Waste Heat Recovery System. Results showed 7,078 tonnes reduction of LNG fuel consumption and 31,919 tCO2e emission savings annually when running the SOFCs on LNG, with the recoverable waste heat from the SOFCs being less than from the current LNG generator sets, requiring additional boiler power to meet a 4 GWh of annual heat deficit.
