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.
In 2010, solar modules cost a little over $2 per watt. Many people questioned whether solar costs could come down another 50%.
Well, here we are today with solar modules well below 50 cents per watt, far cheaper than most expectations. And it wasn’t some breakthrough revolutionary technology -- it’s been the crystalline-silicon solar panel the whole time.
History has a tendency to repeat itself. Our guest, Jessika Trancik, an associate professor at MIT’s the Institute for Data, Systems, and Society, published research earlier this month showing, quantitatively, that lithium-ion batteries have been repeating history and get cheaper, faster, than nearly anyone anticipated.
This matters because it could happen again. The obvious next candidate is hydrogen electrolysis, where experts are saying we might be able to reach the promised land of $1 per kilogram by the end of this decade.
Jessika and Shayle dug into her findings around batteries to see what broader lessons we could learn. We also talked about some other, related and fascinating research she’s done to examine what it will take to reach mass-market EV adoption.
