In 2013, IChemE took a glance into the future and highlighted how many desalination plants there might be in the UK by 2050.
Desalination plants are rare in relatively wet countries like the UK, but fairly common in Southern Europe and the Middle East.
More recently countries such as Australia has invested in desalination plants to solve some of their drought problems, with around eight facilities either built, in progress or planned since 2006.
Worldwide, there are around 13,000 desalination plants in operation or under construction in 150 countries.
By 2050, DesalData predict that the number of desalination plants across the world will more than double with a further 18,500 desalination plants becoming operational.
