这个I-Corps项目更广泛的影响/商业潜力是电网规模储能的发展。随着电网开始依赖间歇性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，需要超过当前锂离子电池技术能力的长时间（8小时以上）能量存储。所提出的解决方案是一种可持续的和负担得起的液流电池技术，其最终可以促进所有社区（例如，这个I-Corps项目是基于在液相化学品中储存能量的液流电池的开发，以允许可扩展和长期的能量储存。这种液流电池技术利用溶解在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，腐蚀性也很低。该技术使用可持续的活性材料，可以在国内以低成本生产。该技术旨在通过往返能源效率和增强的体积能量密度来提供更好的经济性，以限制电池的占地面积。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

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.
