Large-scale storage

Large-scale storage of electrical energy is a huge problem in an array of fields from leveling loads on power grids to providing uninterruptible power supplies. Energy storage is also a crucial technology to enable alternative energies such as solar power and to improve the environmental efficiency of existing energy systems. Battery technologies have improved in recent decades, but they do not have the cycle-life, nor the low-cost required for these applications. This project seeks to build a proof-of-concept system. The data gathered at this stage should also provide enough information to design and build a device for a pilot project in an industrial setting.


The technology from this project was spun out into a startup company, Ambri (formerly Liquid Metal Battery Corporation).
