Sun Meets Sand in the Sahara

Japan and Tunisia Strike Agreement on Solar Power Collaboration

The Sahara Desert in Northern Africa is the world's largest hot desert and due to its harsh climate, has the lowest population density on the planet.

As there have been further advancements in the solar power sector, the logic seems simple...

 Vast, open sSahara Desertpace with direct sunlight —  why not build solar power plants in the desert?

At the second annual Japan-Arab Economic Forum in December, the governments of Japan and Tunisia officially sealed a deal to work together on a project of this nature.

The two countries have been talking since January 2010 about collaboration on a five megawatt pilot solar project in the Sahara. And with this new agreement, they can get the ball rolling on its creation.

Over the past year, you may have heard news of another solar project between Japan and Tunisia's neighbor, Algeria.

The Sahara Solar Breeder Project is a joint initiative by universities in Japan and Algeria that aims to build enough solar power stations by 2050 to supply 50 percent of the world's energy.

Because the Sahara's sand contains the high-quality silicon needed to build solar panels, the project begins by developing the solar panels themselves from desert materials.

Silicon manufacturing plants will be erected in the Sahara; once the panels are operating, a portion of the energy generated will be used to build additional silicon plants.

Hideomi Koinuma at the University of Tokyo leads the Japanese end of the project.

According to Koinuma, creating silicon panels from desert sand has not been attempted before, but it is a logical choice...

"From the viewpoints of quality, quantity and chemistry, Sahara sand is hard to beat for use as silicon for solar cells."

Another goal of the Breeder Project is to send the energy produced around the world using a superconducting electrical grid.

While this aspect of the project has its critics, the goals and vision of solving the world's energy problem, improving science, technology, and living standards in Africa are commendable.

Until Next Time,

Editor's Note: From solar and wind to geothermal and biofuels, Green Chip readers want to know which renewable energy resource will take over where fossil fuels leave off. The answer is...all of the above!

There is no one single solution to today's energy crisis. However, the combination of all viable renewable energy resources, coupled with energy efficiency, conservation and smart grid development will not only lead us to energy independence and a cleaner, more sustainable energy infrastructure — but also to what will soon prove to be the greatest investment opportunity of the 21st Century.
