Battery storage deployment is surging to fill the gaps left by intermittent renewable energy resources. And, sometimes, those gaps extend days beyond what lithium-ion can handle.

For the past six years, Form Energy has positioned itself as the company to solve for the multi-day challenge. What started with splashy renderings and nearly $1 billion in fundraising announcements has evolved into real contracts with utilities like Xcel and Southern Company, and a commercial-scale iron-air battery plant under construction in West Virginia.

Episode 54 of the Factor This! podcast features Form Energy CEO Mateo Jaramillo, a former Tesla executive pushing for deep decarbonization on the grid.

Jaramillo breaks down the technology behind Form Energy's 100-hour battery, how the company was able to convince risk-averse utilities to buy in, and the challenges still ahead for multi-day energy storage.

That's all next on Factor This!
