I work on carbon storage related science. I was talking to a geologist friend of mine who works on one of these projects and she said that it's likely that there is not evidence of mineralization in north sea basalts. This means that the ability to store it in the rocks as a solid may not occur frequently enough to be a storage mechanism. That carbonates detected in the basalts could actually be delivered by fluid transport and not in-situ reactions. That means that the entire idea may be bad and it may not be possible to permanently store carbon there.
