When most people think of batteries these days, they probably think of lithium-ion batteries. But serious questions are starting to be asked about lithium-ion batteries; questions safety, sustainability, performance and the supply of the rare earth materials that go into those batteries. So with all those battery questions swirling, today's show features Hugh McDermott, the senior vice president of business development and sales at ESS. The team at ESS has pioneered a different kind of battery: iron flow batteries. Hugh shares some of the basics about iron flow batteries and how they stack up when it comes safety, sustainability and performance.  Hugh details how the Inflation Reduction Act is a game-changer for the battery sector and how batteries from ESS are already … yes already … playing a role in the long-duration energy storage market.ABS Quality Evaluations Global leader in business assurance servicesSign up for the Renewable Energy SmartBriefFollow the show on Twitter @RenewablesPod
