In this week's episode, Susan and Josh welcome Dr. Jack Brouwer, Director of the Clean Energy Institute at the University of California Irvine, for a discussion on the role of hydrogen as part of California's ambitious plans to transition to a clean energy economy. Dr. Brouwer is also an ordained minister, and the latter portion of the podcast includes a discussion of the relationship between his work and his faith and how it has informed his experience as a scientist and environmentalist.
