Diving into Desalination with Peter Fiske, National Alliance for Water Innovation

My Climate Journey

Dr. Peter Fiske is the Executive Director at the National Alliance for Water Innovation or NAWI. NAWI is a collection of 19 universities, four national labs and 190 plus US water companies committed to developing new technologies to enable distributed desalination and water reuse. They're a five-year, $110 million research program supported by the US Department of Energy in partnership with the California Department of Water Resources and the California State Water Resources Control Board. They're headquartered at Lawrence Berkeley National Lab in Northern California. Peter joined Berkeley lab in 2017. Prior to that, he was the Chief Executive Officer at Pax Water Technologies from 2008 until January 2017, when it was acquired by UGSI Incorporated. Peter holds a PhD in geochemistry and material science from Stanford and an MBA from the UC Berkeley Haas School of Business.

Our conversation today starts with a deep dive into desalination before broadening out into Peter's vision for our water system. Shout-out to former podcast guest Tom Ferguson at Burnt Island Ventures for connecting us with Peter. We've been wanting to learn about desalination and Peter helps us gain a much better understanding of that and so much more.
