Working in a global industry while building out local capacity

We are back for another episode of The Battery Podcast, wrapping up our conversation with Roger Aktins of Electric Vehicles Outlook. In part one we discussed some of the challenges impacting automotive OEMs in the transition to electric vehicle manufacturing as well as some of the interesting business models the transition has let emerge. Whether it is automotive companies becoming battery companies or battery companies becoming energy providers at a grid-scale. But in part two we are delving into the coming requirements for the industry as well as how businesses are already adjusting to a new status quo. China may have a head start on battery development and EVs, but as you’ll hear there are some opportunities for European and North American automakers to get back some of this ground. What you’ll learn:The industry-wide impact of battery passport regulationsFinding value by adding value in a global supply networkWhy investing locally will be critical in finding a foothold in a market increasingly dominated by Chinese manufacturers
