16: Do the Numbers Add Up? Fuel Cells vs Batteries

June 26, 2014 at 12:00PM • 58 minutes • Wiki Entry

Steve Crandall joins us to discuss hydrogen fuel cells vs. lithium batteries. The two alternatives to post-internal-combustion motoring are far harder to assess than it might seem. Both require systems analysis and the systems themselves need to be weighed against the incumbent infrastructure and jobs to be done. We begin with Toyota’s fuel cell sedan announcement and recall Honda’s Clarity. The conversation leads to the observation that technical merit is not always sufficient or even necessary to market adoption success. We note that Toyota supported the Prius through years of low volume. Steve compares this to ATT’s abandonment of a cell service in the 1990?s. Steve compares the energy performance of hydrogen and gasoline and shares a look at the economic conditions necessary for a successful hydrogen fuel cell launch.
