In the former mining area Herrerias in Andalusia, the deep waters of Pit Lake Guadiana show extremely high concentration of dissolved carbon dioxide (CO2). Levels are so high that if it were to bubble up, human beings close-by would be jeopardized. To demonstrate a possible fix, scientists of the Spanish Institute of Geology and Mining, the University of the Basque Country (UPV/EHU, Bilbao) and the Helmholtz Centre for Environmental Research (UFZ) constructed a pilot plant for degassing. A fountain pulls deep water through a pipe to the surface, where the gas can escape from the water. The buoyancy produced by the bubbles provides the energy required for driving the flow. read more
