Having fancy chemistry as in the article is great, but there already exist thermal desalination solutions that require heat (e.g. geothermal, industrial waste heat) rather than work (e.g. electricity for R.O.). For example MED: <https://en.wikipedia.org/wiki/Multiple-effect_distillation> https://en.wikipedia.org/wiki/Multiple-effect_distillation> or MSF: <https://en.wikipedia.org/wiki/Multi-stage_flash_distillation> https://en.wikipedia.org/wiki/Multi-stage_flash_distillation.... Steam is not required for MED. Hot water < 100C is adequate. Many ocean-going vessels already use the waste heat from their engines and MED to make freshwater from seawater. ORC driving RO seems to be most efficient in some situations <https://www.mdpi.com/1099-4300/17/11/7530> https://www.mdpi.com/1099-4300/17/11/7530>, but MED is a simple, no-moving-parts solution that is also efficient.
