The strive for cutting out of a fossil-fuels dependence of countries' economies has driven the global research into developing more sustainable powersources with the ultimate target to completely liberate from coal-red and nuclear power plants. Shifting energy policies to renewable energy resourcesundoubtedly carries many benecial features, but also poses a range of technical challenges, such as the necessity to overcome large uctuations in the energy output from wind or photo-voltaic farms.One solution to this problem proposed in the 1970's is to integrate a large-scale energy storage device such as redox- ow batteries into the electrical grid. The thesis rst presents a brief overview of ow battery technology and applications. Next, a one-dimensional, steady-state, macrohomogeneous mathematical model of a hydrogen-bromine ow battery is developed, described and solved. The results are in good agreement with existing experimental data. Moreover, a parametric study is performed to examine the impact of selected parameters on the overall performance of a single cell. A complete set of eld variable plots is explicitly presented.
