Zero-emission double ended ferries: A concept exploration study

The goal of this thesis has been to develop a concept exploration tool for zero-emission double ended ferries, that determines the feasibility of different energy systems, creates corresponding design parameters and helps decide between zero-emission energy types. <br/><br/>The research goal was achieved in three steps. Firstly, knowledge was...

Fuel Cell and Battery Hybrid System Optimization: Towards Increased Range and Endurance

Aircraft manufacturers are increasingly exploring emission-free flight or emission reduction for larger passenger aircraft. The low energy density of state-of-the-art battery technology limits the application to small, electric, fixed wing aircraft up to a flight time of approximately one hour. To overcome these limits, a combination of fuel...
