Descripción del proyecto
Almacenamiento de energía para lograr un futuro sostenible
A medida que aumenta la demanda mundial de energías renovables, la naturaleza intermitente de fuentes como la eólica y la solar plantea un reto: almacenar el exceso de energía para los momentos de baja producción. Las baterías de flujo redox resultan prometedoras para el almacenamiento estacionario de gran capacidad, pero obstáculos como las limitaciones del transporte de masa y la lentitud cinética dificultan su eficacia. En este contexto, el proyecto RECHARGE, financiado por el Consejo Europeo de Investigación, combinará el flujo pulsátil con electrodos tridimensionales estructurados con precisión, con el objetivo de elevar a nuevas cotas el rendimiento de las baterías de flujo redox. Con un conocimiento profundo y una ingeniería avanzada, el proyecto aspira a una densidad de potencia de 1 000 mW/cm² y una eficiencia de ida y vuelta superior al 85 %. El equipo de RECHARGE anuncia una nueva era en eficiencia y capacidad de almacenamiento de energía.
Objetivo
Electrochemical energy storage is essential if we wish to increase the usage of intermittent energy sources such as windmills and solar panels. With intermittent energy sources it is crucial that energy can be stored to meet demand when production is too low. When targeting stationary storage with large capacity and long storage times, redox flow batteries stand out. However, in order to compete with other energy storage technologies several fundamental challenges remain to be resolved. Mass transport limitations, cell resistivities, pressure losses and slow kinetics still pose major barriers that result in unsatisfactory energy efficiencies and power densities.
In RECHARGE, I propose an innovative and disruptive approach. By combining for the first time pulsatile flow with precisely structured 3D electrodes the battery’s performance can be accurately steered towards improved battery hydrodynamics, allowing to surpass state-of-the-art in terms of maximum attainable power density, diminished efficiency losses and enhanced energy capacity. The combination of targeting an in-depth understanding into how reagent, product and electrolyte transport is governed within the redox flow battery by using in operando characterisation and having perfect control over the electrode geometry and flow field design through advanced engineering approaches, will result in unprecedented control over the mass transport and reaction environment. This will yield a significantly improved redox flow battery with a power density of 1000 mW/cm² and a roundtrip efficiency above 85%.
RECHARGE will demonstrate the impact of achieving perfect control over the hydrodynamic and electrochemical characteristics of a redox flow battery and can thus be considered as the first step towards a new generation of redox flow batteries that will completely redesign the electrode structure and fluid control strategies towards strongly improved battery efficiencies.
