Polyfluoroalklyl substances (PFAS) have been the subject of litigation and controversy due to mounting evidence of their long-term impact on human health.

In this episode cross-posted with S&P Global Commodity Insights' Energy Evolution podcast, reporter Camilla Naschert takes a look at the role of PFAS in the renewable energy sector, talking with industry leaders and academics about what they do and whether it is possible to have a clean energy future without them.
