A Sustainable Future For Not Only Energy, But Water. Repairing the Water
Energy, Water, and our Future
80% of fresh water use is for growing our food.
Why don’t we get moredrinking water from desalinating the ocean?
Peter H. Gleick,president of the Pacific Institute, a nonprofit environmental and water policy think tank based in Oakland, Calif., distills an answer:
The desalination of water requires a lot of energy and, hence,money. The price varies widely from place to place, ranging from just under a dollar up to several dollars to produce a cubic meter (264 gallons) of desalted water, and efforts to reduce the energy requirements have not kept pace with rising energy costs. The cost of drawing freshwater from a river or aquifer is much lower— about 10 to 20 cents per cubic meter—and farmers often pay even less. As a result, desalination currently satisfies less than half a percent of human water needs. Desalination carries environmental costs as well: seawater intakes can suck up small ocean creatures, upsetting the food chain, and the process’s leftover brine is so strong that its return to the ocean can prove harmful to coastal ecosystems. Nevertheless, desalination’s appeal is growing as other sources of water disappear and the price gap closes. Finding a new source of freshwater or building a dam in a place such as California, for instance, can drive costs up to 60 cents per cubic meter. Far more must be done to use water more efficiently, but with the world’s population swelling and the water supply dwindling, the economic tide may soon turn in favor of desalination. ■

INTEGRATION OF NUSCALE SMR WITH DESALINATION TECHNOLOGIES

Nuclear energy plants are attractive energy source for largescale water desalination since the thermal energy produced in a nuclear reactor can provide both electricity and steam to desalt water without the production of greenhouse gases. A particularly attractive option is to couple a desalination plant with the new generation of nuclear plant designs: small modular reactors (SMR). This allows regions with smaller electrical grids and limited infrastructure to add new electrical and water capacity in more appropriate increments and allows countries to consider siting plants at a broader range of distributed locations.
The NuScale SMR plant design is especially well suited for theco-generation of electricity and desalted water. The enhanced safety, improved affordability, and deployment flexibilities of the NuScale design provide a cost-effective approach to expanding global desalination capacity. Parametric studies have been performed to evaluate technical options for coupling a NuScale plant to a variety of different desalination technologies. An economic comparison of these options was performed for each of the different desalination technologies coupled to an appropriately sized NuScale plant capable of providing sufficient carbon-free electricity and clean water to support a city of 300,000 people.
There is a staggering amount of much-cheaper-than-coal nuclear heat available for desalinating the oceans to obtain fresh water.

Comparing "Multi-Stage Flash Desalinators" and "Reverse-Osmosis Desalinators".
Your website author is using Reverse-Osmosis desalinated water from the largest desalinator
in the Western Hemisphere,
located just South of Tampa, Florida.
There are over 16,000 flash water desalinator
stages producing 75 million cubic meters of fresh water per day.
60% is seawater, but 35% is desalination of brackish ground and surface water.

Nuclear Fission Water Desalination + Electricity Generation
Integration of NuScale Small Modular Reactor (SMR) With Desalination Technologies
Note: The first operational
ultra-safe, inexpensive NuScale SMR has been under construction at Idaho
National Labs for about a year. It's power will go to the U.S. Pacific Northwest
A NuScale reactor power plant can have as many as 12 reactor modules, starting modestly but, over time, enabling a rather large city to have all the electricity and desalinated water it needs.
Desalination is extremely energy-intensive but both the energy reserves - the oceans - and the saline water reserves - the oceans - are vast.
Electricity Demand varies widely over both
the day and the year.
This means you can run the nuclear reactor flat-out all the time, shifting between mostly electricity and mostly water every 24 hours, and just pump your extra water into a water reservoir,.
Energy is Coming and Maybe Sooner Than You Think.

The joke about fusion energy is that it's 30 years away and always will be. But recent advances in fusion science and technology could potentially make the first fusion heat as soon as the 2050s.
