Investigation of future low-carbon and zero-carbon fuels for marine engines from the view of thermal efficiency

The use of low-carbon and zero-carbon alternative fuels on marine engine is the main measure to achieve carbon neutrality for shipping sector, thus attracting numerous research on fuel techno-economics, fuel safety and fuel production chains. However, among the factors that determine whether a fuel can finally be successfully marketed, the thermal efficiency of the fuel is very important as one of the cores in determining the operation cost. To evaluate the thermal efficiency of marine alternative fuels, a new theoretical engine cycle, Miller–Sabathe cycle, is proposed to identify thermal effi... Mehr ...
