Burying carbon dioxide from coal-fired plants could increase other pollutants
Power plant emissions that cause acid rain, water pollution and destruction of the ozone layer may actually be made worse by capturing the CO2 and pumping it deep underground, a new study reported online and in an upcoming International Journal of Greenhouse Gas Control suggests.
This increase of other emissions is largely because collecting and burying CO2 — a process called carbon sequestration — requires additional energy, new equipment and new chemical reactions at the plants. And using current technology, meeting all of these requirements releases extra pollutants.
“Other studies mostly just look at one aspect, the carbon capture,” says study coauthor Joris Koornneef, an environmental scientist at UtrechtUniversity in the Netherlands. “This is a fi
