Mark Nelson, managing director of the Radiant Energy Group, joins us for the third installation of our masterclass series, this time all about energy storage. We take a first principles approach focusing on the core concepts of storage to equip the listener with the analytical skills to better understand the contentious energy debates of our time. Mark explains the basic physics of storage, corrects common misconceptions, and gives a numerically literate overview of a few different energy storage technologies. Intro and outro music: Etude Op. 25 No. 12 "Ocean" by Frédéric Chopin (Performed by Mark Nelson live after the interview) Listen to Mark's two other masterclasses: https://www.decouplemedia.org/podcast/episode/2a543c07/this-land-is-mined-the-coal-masterclass https://www.decouplemedia.org/podcast/episode/1ebfcc84/a-natural-gas-masterclass-feat-mark-nelson Note: We apologize for occasional glitches in Dr. Keefer's audio.
