It’s the biggest treasure ever seen on Earth — It’s under the Sahara desert, but impossible to mine

But another potential energy revolution may lie beneath a very different landscape — the Sahara Desert. Deep below its sun-scorched sands could be the largest untapped resource on Earth — one that might be the cornerstone of a green energy future. While invisible to the naked eye, scientists and investors are well aware of its existence. However, extracting this treasure poses technological and ethical challenges, especially since accessing it could significantly harm the surrounding nations in Saharan Africa. Despite this, interest from European corporations is steadily growing.

This isn’t the first time renewable energy pursuits have led to monumental discoveries. Yet, the Sahara’s hidden resource may be beyond our current ability to exploit. If accessed, it could usher in a new era of sustainable development and energy independence. Following the discovery, European attention has increasingly shifted toward Africa. But the main hurdle remains: how to extract the resource without devastating the region.

Among the leading ideas is the large-scale production of green hydrogen — a clean energy alternative that could fuel the next industrial revolution. Yet transporting green hydrogen from Africa to Europe poses major logistical obstacles. As Ben Gallagher of Wood Mackenzie points out, while Africa could help meet Europe’s future energy needs, delivering hydrogen across continents is far from efficient.
