No mention of kWh per liter desalinated...

Good point, that's important info to evaluate the technology, but article does mention waste heat can be used, so maybe virtually zero.

Waste heat can always be reused, but the problem is that the lower the temperature difference the lower the efficiency is, and what you don't extract to do useful work gets converted back to waste heat

At some point it becomes uneconomical to use this waste heat rather than discarding it.
