Based on the estimates of methane resources and the concentration of hydrogen detected so far, scientists have conjectured that the Lorraine region in eastern France, of which Folschviller is a part, could contain 46 million tons of white—or naturally produced—hydrogen. That would make it one of the world’s largest known hydrogen deposits.

This remarkable discovery was not the objective of the project, called Regalor. Instead, it aimed to determine the feasibility of methane production in the Lorraine region and to record the presence of traces of other gases. “Our original research was related to the study of carboniferous sediments in northeast France. This was important as Lorraine was one of France’s largest coal-producing regions,” Pironon said.
