Finding the Goldilocks sites to store carbon dioxide underground

Carbon capture and storage has been heralded as a new technology for reducing greenhouse gas emissions. In an effort to help slow climate change, human-produced carbon dioxide (CO2) is captured at point-source emitters like power stations and sequestered in underground rocks. In porous rocks like sandstone, the CO2 is trapped in tiny spaces or pores, which act like a sponge and soak up the injected fluid.
