The Interchange: Recharged podcast is a leading global clean tech podcast that has been running since 2017. Each fortnight we invite experts and industry leaders from the world of clean tech and energy to join in a deep dive about their tech, the future of their sector, funding and policy impacts.
We aim to provide a platform for start-ups, new companies and organisations who are innovating and solving real world problems in the energy transition. Our listeners are energy experts, industry evangelists who’re interested in companies that do pioneering work to accelerate the transition.
Our host David Banmiller takes our audience through a 45-60 minute exploration of the revolutionary tech these companies are developing, asking about the history, the ongoing work and the vision our guests have for their business. The conversation often turns to funding and policy as well.
Back in 2016, Mateo Jaramillo left Tesla, where he was leading the stationary energy storage business, and started looking for a new challenge to tackle. He took on long-duration energy storage -- not long duration like 8 hours or 12 hours, but days or weeks or more. In 2017 he came on the show to talk about it.
He formed a company, now Form Energy, that has been toiling on this problem in stealth mode. Apart from saying they were building a "metal air" battery, his team held the technology close to the vest.
That is, until last week.
The company announced a $200M Series D financing led by ArcelorMittal, the world's largest steelmaker, and in the process finally made public the technology, which is an iron air chemistry.
Full disclosure: Shayle led Energy Impact Partners’ investment in Form.
Shayle and Mateo discuss the technology itself and the counterintuitive economics that Mateo believes will make it work. They also examine how it beat out the alternatives and how it might complement more efficient, but more expensive lithium-ion. It turns out financial modeling was far more important than spec sheets in understanding the tradeoffs.
They tackle the critical question: Where exactly are the profitable applications of this technology before we hit very high 80% renewables?
They also talk about the semantics of long-duration storage vs. multi-day storage, why Mateo hates holy grails, and potential partnerships with tofu companies.
