Ambri Inc., an MIT-spinoff long-duration battery energy storage system developer, secured $144 million in funding to advance calcium-antimony liquid metal battery chemistry.

The investment round was led by Reliance New Energy Solar Ltd, a unit of Reliance Industries Limited; Paulson & Co. Inc., a group that includes Ambri’s largest shareholder, Bill Gates; and new investors, including Fortistar, Goehring & Rozencwajg Associates, Japan Energy Fund, and others.

The company plans to use proceeds to commercialize and grow its long-duration system technology and to build manufacturing facilities, both in the U.S. and internationally.

Ambri also entered into a long-term antimony supply agreement with Perpetua Resources.  The agreement helps secure a domestic source of antimony for its supply chain.
