"A nivel mundial crece la participación de energía renovable en la matriz energética. Las tecnologías de almacenamiento de energía eléctrica serán cruciales en los futuros escenarios del sector energético. Estas tecnologías permiten regular la fluctuante generación de energía eléctrica generada a partir de fuentes renovables. Bajo el concepto “Power to gas”, se puede obtener hidrógeno con el excedente de energía proveniente de estas fuentes de energía (p.ej. Energía solar y eólica). Por lo tanto, es imprescindible que las técnicas de almacenamiento sean cada vez más eficientes. La generación de hidrógeno mediante electrólisis a alta presión se presenta como posible solución. En este trabajo de tesis que se realizó dentro del convenio de cooperación entre el Institut of Nuclear and Energy Technologies (IKET) y el Instituto Tecnológico de Buenos Aires (ITBA). Se realizaron experimentos con un electrolizador experimental alcalino de alta presión, donde se aumentó la presión hasta los 180bar. Se estudió el comportamiento de las burbujas de hidrógeno y oxígeno generadas de manera individual. El foco fue puesto en el diámetro característico y la velocidad de ascenso las burbujas. Los resultados se compararon con el comportamiento que presentan múltiples burbujas, donde se han observado claras diferencias. Para lograr obtener una generación singular de burbujas, se diseñó un nuevo electrodo y como fuente de energía se utilizó una señal eléctrica pulsante."
