This week, we’re presenting an episode of The Big Switch, a narrative show from Columbia University about how to decarbonize the economy.  Steel goes into pretty much everything around us – from buildings and bridges to the furniture in our homes. And decarbonizing the steel industry is essential because we need steel to decarbonize the world. Think about it. Solar panels, electric vehicles, even our power grid; steel goes into everything we need to fight climate change. But there’s a problem. Steel manufacturing uses a lot of fossil fuels. It’s responsible for 8 percent of global greenhouse gas emissions. In this episode, Dr. Melissa Lott breaks down the race to green, zero-carbon steel. It’s a competition among four key technologies: recycling, carbon capture and storage (CCS), electrolysis, and — everyone’s current favorite — hydrogen. Or, as we call it in this episode, the Usain Bolt of technology. The Carbon Copy is a co-production of Post Script Media and Canary Media. The Carbon Copy is supported by GridX.
