I'm amazed that I'm reading in the same article talking about faults in limestone and "underground trapping of carbon dioxide emitted by power stations".

The water we're pumping down there isn't the only water deep in the earth. Water + C02 = carbonic acid, commonly known to dissolve limestone (frequently the cause of sinkholes when it happens near the surface). Am I the only one who thinks pumping enormous amounts of C02 deep into the ground (where it's going to come into contact with water and limestone) is a really, really bad idea?

Outside of that, very interesting article. Fantastic that they have access to a fault via an old military installation!
