| Sumario: | "The participation of renewable energy in the energetic matrix is increasing continuously and the electrical energy storage technologies will be crucial in the future energy sector scenario. With this technologies, it is possible to regulate the fluctuating electrical energy generation that renewable energy sources present. Under the “Power to gas” concept, hydrogen can be generated with the surplus of those sources (e.g. solar and wind power). Thus, it is essential to increase the efficiency of the storage technologies. The generation of hydrogen by means of high pressure electrolysis is presented as a possible solution.
This master thesis was done within the cooperation program between the Institute of Nuclear and Energy Technologies (IKET) and the Instituto Tecnológico de Buenos Aires (ITBA). Experiments were performed with an alkaline high-pressure experimental electrolyzer, where pressure was rise up to 180bar. It was studied the case of single bubbles behavior, focusing on the typical diameters and rise velocities of hydrogen and oxygen bubbles. The obtained results were compared with a bubbles swarm behavior, where clear differences were observed. To achieve the single bubble generation, a new electrode was design and an electrical pulsed signals was applied as power supply." |
