Description: Das Projekt "PV-H2-Boot Solgenia" wird vom Umweltbundesamt gefördert und von Hochschule Konstanz Technik, Wirtschaft und Gestaltung, HTGW, Institut für Angewandte Forschung , Energiewandlung in Solarsystemen (IAF,EWIS) durchgeführt. 1. Introduction: In view of the increasing problem of energy supply, the University of Applied Sciences Konstanz developed a research boat powered by photovoltaic and fuel cells. The core question of the research project is, if such a combination represents a viable option for recreational and commercial boating. To answer this question, long-time performance-studies of each component by itself and in combination with others in marine environment are necessary. An Information-Management-System (IMS) interfacing to about ninety parameters was developed, providing the basis for analysis. 2. Energy Supply System: The energy supply system consists of two energy conversion units (PV-generator and fuel cell) and two energy storage units (battery and hydrogen tank). A DC/AC-inverter together with an asynchronous motor converts the electrical energy into mechanical energy for the propeller. The voltages between the three fuel cell modules as well as the PV-generator and the battery are adjusted by DC/DC-converters (see figure 1). The hydrogen will be provided by an electrolysis unit within the laboratory driven by a PV-generator and stored on land. One of the research aims is to adapt the hydrogen production depending on solar radiation to the hydrogen demand by the stationary fuel cells (in the laboratory) and the mobile fuel cells (in the boat). 3. Information management system (IMS): The requirements which the IMS has to fulfil are quite complex: 1. a real-time control-system has to operate the boat and process the parameters, 2. a graphical user interface has to provide meaningful and clear information for skipper as well as service and scientist, 3.measured data has to be periodically transmitted to a data bank at the institute for further processing. Use of the Internet gives independence of location. 4. Energy management: Energy management is one of the main tasks of the IMS. One of the research aims is to develop and optimize the management rules. The energy system itself consists of one controllable (fuel cell) and one not controllable energy converter (PV-generator) as well as of two energy storage devices (battery and H2-tank). Parameters affecting the energy management are among others: speed of boat, distance to travel, battery capacity and solar radiation. These parameters are either measured directly or calculated by the IMS. The Solgenia additionally will be used as laboratory unit in teaching: The students shall become familiar with the fundamental problems of managing renewable energies. 5. Graphical user interface: An industrial touch panel PC serves as man-machine-interface. The graphical user interface was divided into two basic groups: skipper and service/scientist. The menu for the latter group was protected by password to prevent an inexperienced skipper from creating any mischief. etc.
