Break through in batteries ‘iron-air’

From Today’s Morning Brew and WSJ comes news of battery developments that can be cost effective for utility scale energy storage. This is critical to advancement of sustainable energy as most sources of sustainable energy are variable in output (think solar). Storing in cheap batteries for use later is critical. This development below lowers the cost.

On the journey to greater adoption of renewables, it’s not enough to make the energy…you’ve got to hold the energy. But how to do so cheaply and at scale remains one of the biggest challenges facing the industry.

Form Energy, a startup backed by Bill Gates and Jeff Bezos, might have cracked the code: batteries made from iron that can hold electricity for days or even weeks. Form’s batteries may be key to achieving President Biden’s goal of a carbon-free power grid in the US by 2035.
