I have always thought it important to be isotopically pure when it came to the material that is active and participate in the LENR reaction because of quantum mechanical issues. The reason why deuterium is functional in the R20 reactor may be because it is isotopically pure. Protium might work as well in the R20, but that isotope might need to be make isotopically pure before it is used in he R20. Getting pure protium is maybe more expensive than deuterium, just in regards to the way that the isotopes of hydrogen are separated.
Ordinary hydrogen may not work in the R20 because it has a significant contaminant of deuterium in its mixture. One of the reasons that H2O is scrupulously cleaned in the R20 flush out procedure is that its protium content is quantum mechanically destructive of the LENR reaction.
