Since you are talking about electrical to electrical, and you compare to lithium batteries in a chart, do you mean that this thing works like a battery?

Like, coupled to solar power, can charge during the day (making hydrogen using some cycle) and provide electrical power during the night

They use a lithium battery as a base for energy density. The lightcell can use a variety of different fuels to create light in the band they want to capture. They 'lean' towards hydrogen, because it's more 'sustainable', but you can get even higher energy densities if you use petrol.
