Putting carbon dioxide away for good by turning it into stone

[LuckyTheDog]

We seriously need to do something about carbon dioxide (CO2) emissions. Besides shifting to renewable energy sources and increasing energy efficiency, we need to start putting some of the CO2 away before it reaches the atmosphere. Perhaps the impacts of human-induced climate change will be so severe that we might even have to capture CO2 from the air and convert it into useful products such as plastic materials or put it someplace safe.

A group of scientists from several European countries and the United States including myself met in the middle, in Iceland, to figure out how CO2 could be put away safely – in the ground. In a recently published study, we demonstrated that two years after injecting CO2 underground at our pilot test site in Iceland, almost all of it has been converted into minerals.

1. Sounds interesting, but

I don't see a discussion on how much energy is needed to facilitate this process. That answer goes to the heart of the viability of such an process, all other assumptions being correct.

2. Carbon capture on a coal fired plant

is said to require between 10% and 25% of the plant's electrical output, depending on the age of the facility and the state of its technology.. There was a good discussion started yesterday on Reddit that answered a lot of questions and raised some new ones.
