NEC Energy Solutions in the US has teamed with battery startup Ambri on the development of energy storage systems (ESS) based around liquid metal battery cells.
The joint development agreement (JDA) will see NEC design and develop an energy storage system based around Ambri’s Liquid Metal Battery technology. NEC will use its proprietary AEROS energy storage operating system and controls to optimize system performance of the Ambri-based energy storage systems for NEC customers that could include utilities, independent power producers (IPPs) and project developers.
Delivery of Ambri cells to NEC is due by the end of the year for production of commercial systems, and NEC has committed to a minimum purchase of 200MWh of Ambri cells. These systems will be targeted at applications with durations of 4-hours or more, and where daily full depth of discharge cycling is expected.
“Based on our knowledge and testing of Ambri’s technology, we feel this chemistry could be a great answer to the energy industry’s need for a low cost, long life storage solution,” said Steve Fludder, CEO of NEC Energy Solutions. “Ambri’s technology enables safe and reliable energy storage with potentially the lowest levelized cost of storage in the industry. NEC’s collaboration with Ambri is a great example of our initiative to explore promising future technologies for energy storage solutions.”
“We’re delighted that NEC’s industry-leading system integration team will develop the first systems with Ambri cells,” said Dan Leff, executive chairman of Ambri. “We’ve received inquiries world-wide from developers, IPPs and utilities for Ambri-based systems who seek a lower cost and safer battery that does not suffer from degradation due to usage. We look forward to helping NEC support these customers with commercial systems based on our technology.”
Ambri’s cells, developed at MIT, are based on its patented calcium antimony chemistry and deliver daily 100% depth of discharge cycling performance for over 20 years with negligible degradation at a significantly lower system cost than other battery storage technologies.
