Ambri facility

Ambri batteries are currently produced in our 40,000+ square foot facility in Marlborough, MA, a 40-minute drive from downtown Boston. The facility is designed for fabrication and testing of our commercial cell products.

Future plans include partnerships for cell manufacturing in each major region of the world.


Supporting accelerated growth

The energy storage market is projected to exceed $50B in annual system revenue in 2030 and Ambri is projecting a sizable share of cell sales at that time.

Ambri has raised over $200 million in equity financing since its founding in 2010. Ambri’s investors include Paulson & Co., Reliance Group, Fortistar, Goehring & Rozencwajg, Japan Energy Fund, Khosla Ventures and Bill Gates. Our investors share a long-term belief that our electricity storage technology will transform the electric power industry everywhere.

Manufacturing Plan

Ambri plans to produce cells and complete DC systems. Its pilot manufacturing site in Massachusetts will host a high-speed cell production line and system assembly & test. These battery systems will be used for trial deployments and then early commercial products in 2023.

Ambri’s high volume production facility is planned to produce multiple gigawatt-hours of systems in the USA starting in 2024.

Outside the USA, Ambri plans to partner with other companies to establish Ambri battery system manufacturing facilities in major regions of the world.

Customers and partners

EPCs, Integrators and PCS OEMs

Ambri’s manufacturing facilities will sell containerized DC-systems to turnkey project companies who will manage the integration with inverters, switchgear, energy management controls, and other AC-level system elements. These companies will also install and commission full AC-systems for project developers, utilities, or IPPs. Ambri battery systems are also available for direct purchase by developers, IPPs and utilities who manage their own projects.

A unique, patented solution

The Ambri batteries were created from patented technology developed by Ambri and the GroupSadoway lab at MIT. Our IP Portfolio contains more than 50 issued patents in the US and around the world. These broad patents cover cell chemistry, cell components, cell construction, cell- to- cell interconnects, system designs, battery management system designs and manufacturing processes. This strong global patent portfolio ensures our unique positioning in the marketplace.
