Thanks!
MIT has a better idea of what to do with the brine.

Split the sodium chloride salt into acid and base.
HCl and NaOH both very useful chemicals used in the millions of Kg every year.
NaOH has a added benefit of being able to absorb CO2 directly from the air when in solution. You could use it to form bicarbonate directly from the air then heat the bicarb to release pure CO2 which again has numerous uses. Very cheap bulk NaOH would yield very cheap pure CO2. NaOH is also capable of extracting raw proteins from green leaf plants when ground up and soaked in an basic solution as protein isolate this is high grade protein for animals feed. Cheap NaOH yield large amounts of protein isolate.
HCl is used all over the chemicals industry. It also has a very interesting property when exposed to cellulose and hemicellulose it depolymerizes both to the original sugars that make up a the base units. Glucose and hextrose having a very cheap source of bulk HCl means you can hydrolysis cellulose to sugars on a huge scale. Monogastric animals(pigs,chickens,humans) cannot eat cellulose but our primary carbohydrate energy source in our blood stream or diet is glucose. Hextrose is eaten by yeasts and any animal or insect with an aerobic gut biota. HCl turns wood scraps, straw, hay, corn stalks any plant materials into sugar that can be feed to animals that don’t have the four stomachs of a cow or goat ect. Cheap HCl in bulk makes for a huge new source of sugars , you can also turn those sugats into ethanol for fuels or food. Yes ethanol is food some people in this very board have a quarter or more of their daily caloric intake by the numbers of ethanol consumption ;)
Any source of cheap acid or base will immediately be put to use for humanity.
Or use it to make a cement replacement with zero CO2 emissions it’s actually CO2negative since the carbonate is formed from atmospheric CO2 should make the greens happy. If nothing else it opens up a massive source of new building materials for the single largest human use substance besides water on earth aka concrete no other material is used more.
