Experiments with neutrons reveal minimal corrosion of the top layer of a naturally occurring CO2 reservoir
The long-term storage of carbon dioxide in porous layers of rock deep underground (carbon capturing and storage, CCS) could contribute to reducing the emission of climate-damaging gases in the atmosphere. An international research team including scientists from Jülich and Aachen investigating a natural 100,000-year-old carbon dioxide (CO2) reservoir in Utah, USA, have now shown that carbon dioxide dissolved in water remains stored in certain types of rock layers far longer than first envisaged (Nature Communications, DOI: 10.1038/ncomms12268).
