I think it's pretty clear with the constantly increasing durations of negative prices, so far we haven't found a way to do so profitably. Carbon capture or anything else for that matter.

Anything that would really love free energy also cost a lot to build and maintain/operate besides electricity. So much that a few hundred hours of free (or even better than free) energy a year is far from enough when you need >90% uptime to make sense. Maybe it makes you go from 95 to 85%, but still clearly it's far more than there are sunshine hours.
