SBIR Phase II: Rechargeable Carbon-Oxygen Battery for Ultra-Low-Cost Renewable Energy Storage

SBIR二期项目更广泛的影响/商业潜力是一种新的超低成本碳氧电池，它提供高能量密度、长时间存储，具有实现100%可再生能源所需的独特基本特性。这种闭环式固定储能系统将间歇性的太阳能/风能发电转变为按需发电，成本低于化石燃料发电。此外，它的高能量密度(在系统层面上比锂离子电池轻3倍，小3倍)将使电动船舶、卡车等的续航里程更远--这是一个次要目标市场--而且与相同能量容量的其他电池相比，用于固定存储的尺寸要小得多。该项目将提供对关键电池组件的放大潜力和设计参数的深入了解。实现100%的可持续能源将产生广泛的社会影响，包括最大限度地减少对环境的影响和改善人类健康。因此，这个碳氧电池小企业创新研究(SBIR)第二阶段项目将通过建模、构建和测试来专注于核心部件的关键技术开发。这将包括组装一系列小型原型反应堆以筛选配置并迭代设计，然后扩展到更大的兆瓦时(MWh)规模的反应堆以集成到演示系统中。第二阶段项目的目标将集中于优化反应堆以实现关键目标指标，包括目标：1)创建和验证优化反应堆的多物理模型，2)设计优化的反应堆、运行条件和材料，以及3)建造和测试几个优化的反应堆，并证明最佳设计具有实现目标指标的潜力。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。

The broader impact/commercial potential of this SBIR Phase II project is a new ultra low-cost carbon-oxygen battery that provides high energy density long-duration storage with unique fundamental properties needed to enable 100% renewable energy. This closed-loop stationary energy storage system will turn intermittent solar/wind power into on-demand power at lower cost than fossil fuel generation. Additionally, its high energy density (3x lighter and smaller than Lithium-ion batteries at system level) will enable longer range electric ships, trucks, etc. – a secondary target market – and a much more compact size for stationary storage than other batteries at the same energy capacity. The project will provide insight into the scale-up potential and design parameters of key battery components. Achieving 100% sustainable energy will have a wide range of societal impacts including minimizing environmental impact and improving human health.This Small Business Innovation Research (SBIR) Phase II project for the carbon-oxygen battery will thus focus on key technology development of the core components by modeling, building, and testing. This will involve assembling an array of small-scale prototype reactors to screen configurations and iterate on the design, followed by scale up to a larger megawatt-hour (MWh) scale reactors to integrate into a demo system. The objectives of the Phase II project will focus on optimizing the reactor to achieve the key target metrics, including objectives to: 1) create and validate a multi-physics model of the optimized reactor, 2) design the optimized reactor, operating conditions, and materials, and 3) build and test several optimized reactors and show that the best design has the potential to fulfill the target metrics.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.
