There’s plenty of research going on, but AFAIK, no particular large-scale push for implementation. I haven’t studied the topic, but my impression is that this is mostly something they can get by with current sources and conservation for a few decades yet. Desalinization is expensive, not just in terms of money, but in terms of energy—scaling it up before absolutely needed is a net environmental harm.
