The great (!) article misses the holy grail of the Energiewende in the chapter „Addressing the challenges of solar intermittency“: a intercontinental smart grid. As shown by data of ENTSO-E in Europe a power system plays a crucial part to overcome intermittency problems of renewables.

How do the costs of long distance, high voltage lines compare to batteries for addressing solar intermittency?

It really depends on what you call "long distance". Anyway, transportation loss for entsoe is public data [1]. You'd need to cross it with production/consumption data [2] in order to get relative numbers.

For instance, France consumed 442 TWh and reported 1.07TWh of losses in 2022, which would be about 2.5% transportation losses.
