The 70% Problem: What Still Needs Electrifying with Michael Liebreich
Summary
Michael Liebreich discusses the "hydrogen soufflé," explaining why many hydrogen projects are failing due to fundamental thermodynamic inefficiencies and rising battery costs. He introduces the "electrification staircase," a framework for prioritizing decarbonization efforts by distinguishing between immediate wins like EVs and long-term challenges like aviation. The conversation also covers the importance of measuring energy by useful output rather than primary input, the future of fuel cells in data centers, and how geopolitical shifts in the US may slow but not stop the global transition…
