CHAPTER

The Efficiency Gap Between Hydrogen and Jet Fuel

The fuel cell electric system is in the upper 40s, almost 50% end to end efficiency. In terms of energy conversion efficiency, there's no gap with hydrogen. We don't expect to be able to capture all of that margin because it almost looks like you're too greedy, right? It looks too good. But we'll have to give some of that back to our customers, obviously. The key issue with hydrogen is on volumetric energy density,. They're a cubic meter of hydrogen versus jet fuel. So hydrogen does take up more volume. It is lighter, right? So it has an advantage from a weight perspective. Hydrogen is the lightest energy carrier outside of nuclear
