Hydrogen, Hybrid systems


The transport sector is investing in new technologies, shifting towards zero-emission propulsion systems. This shift can be observed in the automotive transport sector, but also in maritime transport, where shipowners are evaluating new powertrain configurations and less polluting energy carriers. The innovation in this field is aided by the development of software, based on simulation models representing the powertrain. In this paper, a quasi-static model for a hybrid powerplant is presented. The focus is on hybrid solutions utilizing proton exchange membrane hydrogen fuel cells and batteries. This model can aid the design of powerplants for new hybrid vehicles, or older ones waiting for a retrofit. The model is converted into a Matlab software application for ease of use. Results produced by the model define the powerplant composition and a series of factors, such as fuel cell degradation and hydrogen consumption, that have an influence on running costs. The functionalities of the Matlab software application based on the quasi-static model are demonstrated via one case study considering a harbor tugboat. The results obtained can also be used to measure the technical and economic feasibility of powertrain configurations. The presented model does not include effects related to components aging as all the hardware is considered at beginning of life.
