In recent years, the pursuit of sustainable energy storage solutions has brought aqueous organic redox flow batteries (AORFBs) to the forefront of scientific research and potential industrial application. This perspective critically examines the current literature on AORFBs, with a particular focus on sustainability and performance aspects. We begin by providing an overview of AORFBs and their hybrid (HRFB) technologies, encompassing recent advancements and trends, with a special emphasis on minimizing critical raw materials (redox active species, non-fluorinated membranes, electrodes, etc.) utilized in these systems. A comprehensive discussion on life cycle assessment and circularity of AORFBs and HRFBs with respect to alternative energy storage systems and other RFB configurations is provided. Hereby, an emphasis is placed on the critical reflection of the comparability of different systems, the uncertainties, trade-offs as well as methodological and other challenges. The perspective also summarizes the current state-of-the-art into technoeconomic analyses (TEA), offering insights into cost-effectiveness, scalability potential and their position in the energy storage market. We explore the intersection of technology and policy by discussing the legal and regulatory frameworks shaping the development and deployment of AORFBs. Through this holistic approach, we aim to advance the understanding of AORFBs’ role in fostering a sustainable energy future, guiding both academic research, industrial innovation and policy making.

摘要

In recent years, the pursuit of sustainable energy storage solutions has brought aqueous organic redox flow batteries (AORFBs) to the forefront of scientific research and potential industrial application. This perspective critically examines the current literature on AORFBs, with a particular focus on sustainability and performance aspects. We begin by providing an overview of AORFBs and their hybrid (HRFB) technologies, encompassing recent advancements and trends, with a special emphasis on minimizing critical raw materials (redox active species, non-fluorinated membranes, electrodes, etc.) utilized in these systems. A comprehensive discussion on life cycle assessment and circularity of AORFBs and HRFBs with respect to alternative energy storage systems and other RFB configurations is provided. Hereby, an emphasis is placed on the critical reflection of the comparability of different systems, the uncertainties, trade-offs as well as methodological and other challenges. The perspective also summarizes the current state-of-the-art into technoeconomic analyses (TEA), offering insights into cost-effectiveness, scalability potential and their position in the energy storage market. We explore the intersection of technology and policy by discussing the legal and regulatory frameworks shaping the development and deployment of AORFBs. Through this holistic approach, we aim to advance the understanding of AORFBs’ role in fostering a sustainable energy future, guiding both academic research, industrial innovation and policy making.
