Descripción del proyecto
Un electrolizador de membrana de intercambio de protones rentable y de alta presión impulsa la producción de hidrógeno verde
El hidrógeno verde, producido por electrólisis, podría convertirse en un vector energético fundamental para integrar las energías renovables en los sectores de la energía y el transporte. El equipo del proyecto PRETZEL, financiado con fondos europeos, tiene como objetivo desarrollar un sistema electrolizador de membrana de intercambio de protones (PEM, por sus siglas en inglés) de 25 kW. Este innovador sistema, que puede alcanzar hasta cien bares de presión diferencial, mejorará enormemente los problemas de eficiencia, coste y durabilidad que limitan en la actualidad la electrólisis de PEM a gran escala. Se espera que el electrolizador funcione entre 4 y 6 Acm^(-2) y 90 °C con una eficiencia sin precedentes del 70 % durante más de 2 000 horas. El uso de revestimientos de metales no preciosos y de soportes catalizadores avanzados de aerogel cerámico reducirá los costes de capital. El hidrógeno producido por el generador de hidrógeno de alta presión se utilizará en estaciones de prueba de pilas de combustible.
Objetivo
Green hydrogen produced by electrolysis might become a key energy carrier for the implementation of renewable energy as a cross-sectional connection between the energy sector, industry and mobility. Proton exchange membrane (PEM) electrolysis is the preferred technology for this purpose, yet large facilities can hardly achieve FCH-JU key performance indicators (KPI) in terms of cost, efficiency, lifetime and operability. Consequently, a game changer in the technology is necessary. PRETZEL consortium will develop a 25 kW PEM electrolyzer system based on a patented innovative cell concept that is potentially capable of reaching 100 bar differential pressure. The electrolyzer will dynamically operate between 4 and 6 A cm^(-2) and 90 °C achieving an unprecedented efficiency of 70%. This performance will be maintained for more than 2000 h of operation. Moreover, the capital cost of stack components will be largely reduced by the use of non-precious metal coatings and advanced ceramic aerogel catalyst supports. Likewise, the system balance of plant (BoP) will be optimized for cost reduction and reliability. The high pressure hydrogen generator will become part of the product portfolio of a German manufacturer but at the end of PREZEL, this company will establish a supply business partnership and R&D collaboration with France, Spain, Greece and Rumania, strengthening and consolidating cooperation among EU states with contrasting economies. Lastly, the hydrogen produced by the PEM electrolyzer will not be wasted, but rather used for feeding the fuel cell test stations in one of the partner’s laboratory.
