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.

这个i-Corps项目的更广泛的影响/商业潜力是开发电网规模的能量存储。随着电网开始依赖间歇性的太阳能和风能资源进行清洁能源发电，必须同时整合储能能力。研究表明，需要长时间(8小时以上)的能量存储，超出了当前锂离子电池技术的能力。拟议的解决方案是一种可持续且负担得起的液流电池技术，它可以最终促进所有社区(如城市、离网地区、低收入住房和大公司/行业)经济可靠的可再生能源整合，确保环境公平和能源公平。该i-Corps项目基于开发液流电池在液态化学品中存储能量，以实现可扩展和长期的能量存储。这项流动电池技术利用了溶解在pH中性水中的分子工程有机分子。在操作过程中火灾风险最小，如果发生泄漏，腐蚀性很低。该技术使用可持续的活性材料，可以低成本在国内生产。该技术寻求通过往返能源效率和增强的体积能量密度来提高经济性，以限制电池的占地面积。这项技术可以为高度可变的间歇性可再生资源提供长期的可靠性。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
