"The corresponding lowest energy consumption of ammonia synthesis based on the light power can be calculated to be approximately 322 kWh kg−1 NH3 (Fig. 3b). This value is significantly higher than that (10 to 13 kWh kg−1 NH3) of the H–B process at an industrial scale" still way to go. found nothing about the "subsequent hydrolysis" step, skimming the article |

It isn't clear to me how they're pricing the H-B process there, industrial HB uses hydrogen from hydrocarbons. An apples to apples comparison would at least add the energy you could get from burning the hydrogen instead, but arguably should compare with H-B where the hydrogen comes from electrolysis of water.
> "subsequent hydrolysis"
As far as I can tell, you just add water. zap rinse repeat. I'm a little skeptical that their yield figures were for Li2O though the repeated process has you cycling through LiOH after the first pass.
