The US Department of Energy just committed a $400 million loan to battery maker Eos.

    I wonder if it can be cheaper and better at scale than iron-air batteries. Those seem inexpensive to make, and can carry a large enough capacity if you put a whole lot of them in parallel with each other, and have a long lifetime. They’re just really heavy for their amount of energy density and fairly low current per cell, but that shouldn’t be a problem when building enough to be grid-scale.

      Energy density on these are woefully inadequate for cars, but that doesn’t matter for stationary storage which is what this is for.
