Cost mostly. It's really expensive, enough so that the first ~80% of the shift off fossil fuels is going to happen using solar + wind + storage.
To make sense for the last 20%, it's going to need to come down in price enough to beat the emerging longer-duration storage technologies. Not at all clear to me that it can do that.
