A Rusting Battery In Minnesota Could Unlock The Electric Grid Of The Future

The title of this post is the same as that of this article on the West Central Tribune.

This is the first paragraph.

A pilot project between Minnesota’s second largest supplier of electricity, Great River Energy, and a Massachusetts start-up claims to have a breakthrough in battery technology that would allow for vast expansions of renewable energy on the power grid.

The article goes on to describe Form Energy’s batteries and gives a couple of pictures.

I’m not sure, but it looks like the battery can supply 1 MW for a hundred hours.

Form Energy have impressive backers and have been secretive in the past, but the concept of using iron oxide (rust) as an energy storage medium sounds to me, to be a challenging idea.
