Hydrogen cost could equal 50-cent gasoline, with renewable energy: study

12. That 86% figure is pretty squirrely

I found one paywalled journal article related to this project and otherwise a bunch of press releases and articles based on them. It is apparently achieved because their not looking at the energy in electricity but thermal energy. In fact, a big part of their pitch is really about the ability to feed hydrogen into natural gas systems at low concentrations, using it to make methane, district heating systems, etc. in addition to doing things like filling hydrogen car fuel tanks. The 86% is an "energy utilization rate" that isn't rigorously defined in any source I've been able to track down.

I don't think that figure describes what happens to the transportation use of renewable energy to produce hydrogen, which was the subject of the OP.
