How to Turn Saltwater into Gold

Water covers most of the planet. Yet, fresh drinking water remains a precious commodity in many places. It’s one of life’s rich riddles.

A Spanish company has a solution. Abengoa S.A. (MCE: ABG.B) signed a 27-year contract with Morocco to make seawater drinkable in the port city of Agadir.

It’s a big deal. It could change the course of human history.

It’s no surprise that new technologies can tackle big problems … like cost-effectively removing salt from water.

Advances in computer power and software analytics mean engineers have more tools than ever. They are pushing the envelope everywhere.

Abengoa’s desalination project will start by producing 275,000 cubic meters of potable water every day. Of that, 150,000 cubic meters will go to drinking. The rest will go to farms for irrigation.

For perspective, humans in developed countries need 3.8 cubic meters of water a day. This includes water for drinking, washing, agriculture, and industry.

By that standard, the Abengoa project will initially supply water to 72,500 people. And production could ramp up by 63% to 450,000 cubic meters a day.

Desalinization plants can save these women from walking many miles to forage for drinking water.

Desalinization projects are not new. In fact, Deutsche Welle reports some 21,000 plants are already in service.

However, the Agadir project stands out because it uses sustainable power and a special filtration system.

The Middle East builds most of the world’s desalination plants. There, many people must live in the desert. So, drinking water is scarce. But there’s plenty of inexpensive oil.

In Saudi Arabia, oil-fired plants heat seawater, creating vapor. Filtration systems then collect the water. The salt particles get left behind.

This thermal process works in Saudi Arabia where the cost of finding oil is low. But, in most parts of the world, it’s a non-starter.

Most of Agadir’s power will come from solar energy. It’s delivered by high-tension wire from the Noor Ouarzazate power plant, a giant collection of mirrors and steam turbines on the edge of the Sahara.

Abengoa will use that power to run a reverse-osmosis filtration system. It will force the salty water through a series of filters. Eventually, only salt-free water will pass through.

In theory, the addition of solar power and reverse osmosis makes this project less expensive than traditional thermal desalination. And it opens the door to scaled-down projects in Africa.

The World Health Organization lists drinkable water as the biggest obstacle faced by poor African countries. A lack of potable water is the leading cause of illness.

According to a 2012 study by the Center for Strategic & International Studies, it also hampers economic development. This leads to civil war and promotes terrorist organizations.

And all this strains the developed world’s economy, too.

Drinkable water is a basic human need. Since 97.5% of the water on Earth is saltwater, desalination is a logical development.

And it makes sense for the developed world to bring the technology to developing countries.

The technology will create new business models. In the developed world, I’m already looking into semiconductor-design and data-analytics participants.

In the developing world, desalination changes everything.

Secure sources of drinkable water promote industry and a higher standard of living. This makes e-commerce possible. It means more economic development, and data centers and cell phone towers.

It is the start of something big. I’ll be discussing how to take advantage in coming months.

Best wishes,

    This should be interesting. The power to evaporate the water is a big problem, but it’s only one problem. The other big problem is what to do with the salt. And, there is a lot of it too. The problem is that salt in quantity is poisonous. It will destroy farmland. You also can’t throw it back in the sea or it will destroy the local ecology and fisheries.

    Arabs truck the salt out into the Rub al Khali, the so-called Empty Quarter in the center of the Arabian peninsula and dump it on the ground. There is virtually nothing out there that would be harmed by the salt and it nearly never rains to wash the salt into the inhabited areas. But Africa is quite a different matter. It is much more densely populated than Arabia. In Africa there are rains that can disperse the salt and harm the lands ability to raise crops.

    Drinking water has been possible if expensive for decades, but agricultural water is another matter entirely. Agricultural water is measured in “foot acres”, that is the water needed to submerge one acre of land to a depth of one foot. It is equal to 325,000 gallons. It will be interesting.
