Yes, @ENERGY experts mentioned #LHV for all electrolyzers would align with #HFTO fuel cell work⬇️, but today most hydrogen is for refining/fertilizer/chemicals, very little in new areas like transpo/power gen.

Go with what's accurate: #HHV !

Even the #DOE #Hydrogen & Fuel Cell Technologies Office #HFTO can mess up higher #HHV & lower heating values #LHV:
-Liquid water reactant → #HHV⬇️
Includes ΔHvap of H2O (Use for #PEM #LAE #AEM electrolyzers)
-Water vapor reactant → #LHV
H2O vapor feed (Use for #SOEC electrolyzers)
