In an increasingly thirsty world, there is much potential in desalination, the process of removing salt from seawater. But desalination has historically posed challenges - it consumes massive amounts of expensive energy, produces a waste called brine, and raises concerns about impacts on aquatic life.

So how is desalination becoming more of an option for the creation of freshwater?

That question is answered in this episode with Peter Fiske, Executive Director of the National Alliance for Water Innovation and Director of the Water-Energy Resilience Research Institute.

Peter explains how desalination is becoming more efficient and effective through innovation in membranes, technologies for handling brine, and extraction of valuable elements. He also talks about upcoming pilot projects, the role of desalination in addressing Western water scarcity, and international collaboration.
