American Superconductor's 1st gereration superconductor wire operates at around 77K (depending on the local magnetic field, current demsity etc.) and build magnets from this which operate at 20-40K meaning liquid helium cooling is not required. Improvements will no doubt be made on this. I believe HTS magnets will eventually replace rare-earth magnets (such as sintered NdFeB magnets) in wind and wave energy devices, but this is in the distant future.

I'm not so sure that you need to wait all that long. There are a number of groups working on this.
