US Utility Xcel To Put Form Energy’s 100-hour Iron-Air Battery At Retiring Coal Power Plant Sites

The title of this post is the same as that of this article on Energy Storage News.

This is the first two paragraphs.

‘Multi-day’ battery storage startup Form Energy’s proprietary iron-air battery is set to be deployed at the sites of two US coal power plants due for retirement.

Form Energy said yesterday that definitive agreements have been signed with Minnesota-headquartered utility company Xcel Energy for the two projects, one in Minnesota and the other in Colorado.


On their Technology page, they say this about their battery storage technology.

Our first commercial product is an iron-air battery capable of storing electricity for 100 hours at system costs competitive with legacy power plants. Made from iron, one of the most abundant minerals on Earth, this front-of-the-meter battery will enable a cost-effective, renewable energy grid year-round.

They also seem to be very much into grid-modelling technology. As I’ve build mathematical models for sixty years, I like that!

It does seem Form Energy is on its way.
