this is solar power and operate 24/7 in full load.
Check the power rating. This is woefully insufficient. Moreover it does not really operate 24/7 even if it uses thermal storage, it will generate almost nothing in the winter when the demand is highest.

The innumeracy of nuclear opponents never fails to amaze me. The largest and only osmotic power plant ever constructed produces barely enough power for two electric kettles. Even if its output was doubled as suggested in the article you linked to, 125000 such power plants would be required to replace just one nuclear reactor.

Wave power is just as intermittent as wind power. It generates substantial energy only when there are large waves.

A smart grid is supposed to be about demand management, so that when there is no wind, the poor who cannot afford to pay more for electricity are cut off first, and the rich are unharmed. It is not about a worldwide grid, which is technically impossible - the transmission losses would make it impractical, not to mention the incredible cost of this scheme.
