Optimization study of a hybrid powertrain: Optimization of the system components and energy management of a zero-emission hydrogen powered boat

The company H2 Marine Solutions has designed a zero-emission hydrogen powered boat. This boat is compared to its fossil fuel counterpart more than twice as heavy. The reason for this is that the system components that are used in the hybrid powertrain of the hydrogen powered boat are heavier. The main question of this research is: How can we...

Creating phylogenetic networks from clusters

In biology, phylogenetics is the study of the evolutionary history of and relations between e.g. species. Such data are often represented in trees. Remarkably, trees lack the representation of reticulation events, such as hybridization, while such events are believed to be important. One of the reasons why trees are widely used, is the enormous...

Future City Hydrogen: Reality or Utopia?: A techno-economical feasibility study of an optimal stand-alone Solar-Electrolyzer-Battery-FuelCell system for residential utilization

The population worldwide is growing rapidly which leads to an increase of the energy demand. Simultaneously, the established energy resources are being depleted and contribute negatively to the climate. The necessity for a sustainable and inexhaustible energy source, to deal with the increasing energy demand in an ecological friendly approach,...

Efficiency analysis and design methodology of hybrid propulsion systems

A hybrid propulsion system features both a diesel engine and an electric motor for propulsion. The degrees of freedom with power generation raise the question how this division between power can be optimised in such a way that the engines are running with their optimal fuel efficiency. A generalised method to determine the power generation for...
