A new era of desalination | FT Food Revolution

For decades it’s been hoped that seawater could be desalinated at scale, to provide drinking water and irrigate crops. But desalination plants still only provide a fraction of the world’s fresh water, largely because they’re expensive to build and use a lot of energy. But as the FT’s Gill Plimmer explains, advances in technology and green energy efficiency mean desalination is now becoming a more viable proposition.

Green desalination can bring about not only a revolution in agriculture, but also reclaimed deserts, lithium, battery catalysts, and neo-forests. Knowledge capital pays off again, and again.

The main problem with desalination is Brine water waste (the residue). They dump it back into the sea. Countries around Persian Golf and Mediterranean Sea are doing this for the last 50 years. They almost killed everything in the sea. The environmental impact is very severe.

I wish they could reprocess the brine into sodium ion batteries.

@user-nb5sr7by6y 3 ай бұрын

Modern techniques would remove all of the brines for lithium, separate the creams for battery catalysts, and make hydrogen from the water, all using renewable energy. Drinking water, farm reservoir service, and buried reserves should be accounted for, as well. The Salton Sea extraction methods bode well for the industry.

@MultiMenvafan 3 ай бұрын

What I never understood is why Brine isn't "pre-mixed" with sea water before released into the ocean. It's a matter of concentration as I understand it so diluting it by 10:1 should make it less of a problem. Is it just a matter of cost or am I missing something else?

@johanhagner2341 3 ай бұрын

One would think the brine would be useful in saltpans. Should be competitive salt enterprise if it gets extra salty water for free

@stickynorth 3 ай бұрын

Those brines should then be filtered or lithium and uranium both of which can be extracted from seawater... Those would give the whole process that much of an economic incentive to use and reuse those brines more effectively...

The process to desalination for agricultural is much easier than for the purity level for drinking water. Drinking water is not the problem its agriculture needs

@autohmae 3 ай бұрын

Pretty certain this is just the start, the next step is also more greenhouses, often probably without using the sunlight directly but using growth lamps. Why ? Because weather is less predictable and because costs are coming down.... including of energy.

People often think and say "just use the seawater if it's rising to provide water for us all, remove the salt". Yeah, you have no idea how much energy is needed for that and the cost of investments in infrastructure required. Your water bills would skyrocket.

Where will all the salt extracted from desalination go? Releasing that back in the water wouldn’t harm the environment and sea life?

Well FT like always obfuscate the most harmful part. The desalination industry has kill everything in the sea from Great barrier rife to smallest fish in the Persian Golf. It is the most harmful industry ever existed.

@inigomontoya4109 3 ай бұрын

Tossing the salt back into the sea is doable under certain circumstances as the amount of salt being added is tiny compared to the size of the sea. The issue is people try to skimp on the cost of this and try to directly dump it back into the sea causing dead zones of high salinity around the dump pipes. You have to basically spread out the dump zones across a massive area so that the amount of salt brine in any particular area is non noticeable. Some plants do this but it is much much more expensive

@@inigomontoya4109 the problem with brine water is that it doesn’t mix with sea water as its density much higher. It goes to the bottom of the sea and creates a super salty layer. This kills all the vegetation on the sea floor and hence the food source of many fish types.
