In the 90s batteries powered your camcorder and boombox. Then your phone. Now they’re running your electric vehicle (EV), and in some cases, even your house.  At what scale will batteries meaningfully reduce greenhouse gas emissions? We may be nearing an inflection point with electric vehicle batteries, but we’re nowhere near as close with grid storage technologies. What’s it going to take to get there?   Guest host Lara Pierpoint explores this question with battery expert – David Schroeder, chief technology officer of Volta Energy Technologies, a venture capital firm focused on storage. They talk about David’s two least favorite phrases in the battery world: “range anxiety” and “long duration.” They also survey different applications for storage and whether there’s a holy grail technology that can satisfy that variety of demands. .  Then, they zoom in on lithium-ion technology, the workhorse of EVs and storage. They cover safety, recalls, supply chains, and why lithium ion is so expensive for grid applications. But David explains why he’s optimistic that declining lithium-ion costs will fall even further. They also discuss recycling, flow batteries, thermal storage, and mechanical storage by lifting and lowering heavy blocks of concrete. Oh, and nuclear watches. Catalyst is supported by Antenna Group.
