The broader impact/commercial potential of this I-Corps project is the development of grid-scale energy storage. As electric grids begin to rely on intermittent solar and wind resources for clean energy generation, energy storage capacity must be integrated concurrently. Studies have demonstrated the need for long-duration (8+ hour) energy storage beyond the capabilities of current lithium-ion battery technologies. The proposed solution is a sustainable and affordable flow battery technology that wmay ultimately facilitate economical and reliable renewable energy integration for all communities (e.g., urban cities, off-grid areas, low-income housing, and large corporations/industries), ensuring environmental justice and energy equity.This I-Corps project is based on the development of flow batteries storing energy in liquid phase chemicals to permit scalable and long-duration energy storage. This flow battery technology utilizes molecularly engineered organic molecules dissolved in pH neutral water. There is minimal fire risk during operation and low corrosivity if spillage occurs. The technology uses sustainable active materials that can be produced domestically at low-cost. The technology seeks to provide improved economics with round-trip energy efficiency and enhanced volumetric energy density to limit the footprint of the battery. This technology may allow for long-term reliability for a highly variable intermittent renewable resources.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力是电网尺度存储的开发。随着电网开始依靠间歇性太阳能和风力资源来产生清洁能源，必须同时集成能量存储能力。 研究表明，超出当前锂离子电池技术能力之外的长期（8小时）储能的必要性。提出的解决方案是一种可持续且负担得起的流量电池技术，最终促进了所有社区的经济可靠的可再生能源整合，例如，城市城市，离网地区，低收入的房屋以及大公司/行业，大型公司/行业，确保环境正义和能源公平。这种流量电池技术利用分子设计的有机分子溶于pH中性水。如果发生溢出，操作过程中的火风险很小，腐蚀性较低。该技术使用可持续的活性材料，可以在低成本下在国内生产。该技术旨在通过往返能源效率提供改进的经济学，并增强体积能量密度，以限制电池的足迹。该技术可以为高度可变的间歇性可再生资源带来长期可靠性。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响审查标准，被认为值得通过评估来获得支持。
