Egypt must have a surplus of natural gas for a long time to justify this.
...Multiple scientific studies have highlighted that Egypt in recent years has increasingly been suffering from a serious problem with water shortage.The river Nile’s fresh water is continuously decreasing due to human activity. Uneven distribution of water, inefficient agricultural irrigation techniques and misuse of scarce water resources are some of the reasons the country’s water security is under threat.......Egypt’s volume of renewable freshwater is just 20 cubic meters per person, a significantly low figure compared to international standards. CAPMAS, the country’s official statistics agency, said in 2014 that since 1947, Egypt’s annual water quota per person has declined by 60 percent. By 2025, the situation is projected to become even worse, with the country facing a situation of “absolute water scarcity”....

@IsailedawayfromFR Most of the large scale seawater desalination efforts I've seen depend largely on waste heat from nearby facilities. Doing it otherwise would be exorbitantly expensive I would think.
A very large desal plant was completed in Carlsbad CA. A replica is planned up the coast in Huntington Beach CA.dubbed: "the nation’s largest, most technologically advanced and energy-efficient seawater desalination plant." Uses most advanced technology which is from Israel, btw.https://en.wikipedia.org/wiki/IDE_Technologies
So not only will California gas remain expensive, but the cost of water will really go sky-high as the facility operates under a take or pay provision that burdens the seller.Since the plant will increase sailinities into the ocean, look for the enviro-wackos to scream murder.
Waste heat utitlization is a good way to utilize otherwise unproductive energy, but I think the really big ones run on natural gas where supply is plentiful and cheap, such as exists along the Arabian Gulf.
The enviro whackos were not able to block the Carlsbad plat, which went into operation in 2015. The largest desal plant in the US.The other plant is a copy of that one, and has not been reached final approval, eg. the enviro whackos may succeed in blocking it. I trust the technology is good enough for the "environment," having weathered many false warnings of catastrophe in the past. I can't predict water prices. If Northern California cooperated, water could be moved to the largely arid South.
I am somewhat familiar with some of those plants along the Arabian Gulf and all use waste heat to the maximum extent possible although they have absolutely no need to do so there for the reason you state. Copious amounts of gas is still being routinely flared in that region.
I didn't follow that line of reasoning. Are you saying they do not need to worry about wasting heat?BTW, you may know better, but I thought most desal plants were situated nearby power plants,
@IsailedawayfromFR Perhaps i failed to make myself clear enough in my earlier post and no I'm not saying that although that is not the major consideration typically.Those power plants you mention use gas to fire boilers that generate the superheated steam that run the turbines which drive the generators. The water used to feed the boilers in that procees is highly purified and very expensive to produce so it is reclaimed to the maximum extent possible. The condensers used to cool down the steam exhausted from those turbines in order to recycle the condensate for reuse as boiler feedwater typically are also flash evaporators that remove salt from seawater. There may also be evaporators directly gas fired as well if there is more demand for fresh water than can be supplied by recapturing waste heat alone.
