Electrochemical energy storage and conversion technologies play a significant role in the storage of energy produced by renewables such as wind and solar as well as in the generation and utilization of clean energy carriers (e.g., hydrogen). Redox flow batteries (RFBs) are promising for grid-scale long-duration energy storage as required for the integration of intermittent renewable energy into the grid. Nafion membrane takes up to 40% of the stack cost in RFBs. The design, development, and manufacturing of sustainable low cost polymer membranes with high selectivity and high stability represent a major challenge for the development of cost-effective electrochemical technologies for energy conversion and storage.With the support of ERC-funded curiosity-driven fundamental research, we have developed a new generation of hydrocarbon-based membranes that overcome the performance limitations found in all existing ion exchange membranes, particularly for redox flow battery applications. This proof of concept grant would provide a timely opportunity to explore the pathways to commercialization of our new ion-selective membranes for grid-scale energy storage as well as for hydrogen technologies. We propose to work on: (1) Scaling uppolymer synthesis, (2) Manufacturing membranes via roll-to-roll casting to produce meter-square-sized membranes and engineering to optimize membrane performance, (3) Validating performance of these large-area membranes in flow battery stacks, instead of small single cells, for more intense evaluation of their performance under real-world conditions. This project will also involve collaboration with academic and industrial partners including large energy and small start-up companies, from green manufacturing to performance validation in battery stacks. The project will help advance the ground-breaking research toward commercialization.

电化学能源存储和转化技术在可再生能源（例如风能和太阳能）以及清洁能载体（例如氢）产生和利用中产生的能源中起着重要作用。氧化还原流量电池（RFB）对于将间歇性可再生能源整合到网格中所需的需要的网格尺度长期储能很有希望。 Nafion膜最多占RFB中堆栈成本的40％。具有高选择性和高稳定性的可持续低成本聚合物膜的设计，开发和制造是发展具有成本效益的能量转换和存储电化学技术的主要挑战申请。这项概念证明的赠款将为探索我们新的离子选择膜商业化的途径提供及时的机会，用于网格尺度的储能以及氢技术。我们建议进行：（1）缩放尺度的象征，（2）通过滚动铸造制造膜，以生产仪表尺寸尺寸的膜和工程以优化膜性能，（3）验证这些大区域膜在流量堆栈中的性能，而不是小型单细胞中的单个细胞，以使其更加强烈的评估，以使其更加强烈的评估，以实现实际情况。该项目还将涉及与学术和工业合作伙伴的合作，包括大型能源和小型初创公司，从绿色制造到电池堆的性能验证。该项目将有助于推进开创性的研究，以实现商业化。
