This project had its kick-off meeting in September 2020. As part of their technology development, the project team also completed their Codes and Standards evaluation to assess how they might affect long-duration storage deployment. This included a comprehensive review of relevant safety codes for similar battery technologies, cross-referenced with an internal Failure Mode and Effects Analysis (FMEA) which ranks expected failure modes by priority. This will lead to future work supporting appropriate safety testing procedures that will be both written and executed for Sub-Scale Cells and Full-Scale Cells (FSCs). The results will be evaluated to improve safe design of FSCs.
This project will be the first fielded and independently verified prototype-scale demonstration of a new form of low-cost, long-duration thermal energy storage that has the potential to be over 100-times cheaper per kWh than lithium-ion energy storage and provide multiple days-to-weeks of continuous zero-carbon backup power in customer and grid applications. The prototype will use breakthrough battery materials sourced from super-abundant, ultra-low-cost, globally scalable materials from existing supply chains.
Compared to previous low cost, long-duration energy storage technology prototypes, this module will have an improved energy footprint by 30 times, duration improved by a factor of 4, and round-trip efficiency increased by 10%, ea
The laboratory evaluation of this novel, long-duration storage technology will provide data about the optimal use of multi-day battery energy storage under a range of simulated use cases. This information should help utilities, r
