The zero-emission fuel may exist in abundant reserves below ground. Now large sums are being invested to look for it
For more than a decade, the village of Bourakébougou in western Mali has been powered by a clean energy phenomenon that may soon sweep the globe.
The story begins with a cigarette. In 1987, a failed attempt to drill for water released a stream of odourless gas that one unlucky smoker discovered to be highly flammable. The well was quickly plugged and forgotten. But almost 20 years later, drillers on the hunt for fossil fuels confirmed the accidental discovery: hundreds of feet below the arid earth of west Africa lies an abundance of naturally occurring, or “white”, hydrogen.
