While plenty of question marks still hang over the prospect of carbon capture and storage, MIT believes it's ruled out one: the US, it says, has enough capacity in its deep saline aquifers to store at least a century's fossil fuel emissions.
The Midwest Geological Sequestration Consortium (MGSC) has embarked on the first million-tonne demonstration of carbon sequestration in the US.
Storing carbon dioxide underground poses little threat to health, scientists from the University of Edinburgh claim.
Virginia Tech researchers plan to inject some 20,000 tons of carbon dioxide (CO2) into a coalbed methane field in southwest Virginia, as part of a Department of Energy project.
Carbon Capture and Storage (CCS) underground could trigger earthquakes, a Stanford geophysicist warns.
Carbon sequestration - much touted as a cure-all for unsustainable levels of polluting emissions - could increase contaminants in drinking water ten-fold, a new study has found.
