Form Energy is a bit light on details, but it looks like they are using a water based electrolyte, add oxygen, get electric power and rust when discharging, then add electric power and get iron and oxygen when charging.
The project mentioned here is setting the iron powder on fire and need to use a steam turbine to get electric power out of it. So different tech.

There is a whole industry of flow batteries emerging also.
