"Pilot projects bury carbon dioxide in basalt." Report from Nature News & Comment_26 July 2013

 JEFF TOLLEFSON writes in Nature

"By early August, scientists will have pumped 1,000 tonnes of pure carbon dioxide into porous rock far below the northwestern United States. The goal is to find a permanent home for the carbon dioxide generated by human activities.
Researchers at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) in Richland, Washington, began the injections into the Columbia River Basalt formation near the town of Wallula on 17 July. The rock contains pores created as many as 16 million years ago, when magma flowed across what is now the Columbia River Basin. Bubbles of CO2 migrated to the edges of the magma as it cooled, forming layers of holes sandwiched between solid rock (see 'Rock steady').
In pumping emissions back underground, “we are returning the carbon dioxide from whence it came”, says Pete McGrail, an environ­mental engineer at the PNNL who is heading the experiment, part of a larger energy-department programme on ways to sequester carbon."

KEEP-UP THE GOOD WORK LADS.
ON THE STORAGE SIDE OF THE CO2 OUTPUT ACCOUNTANCY (IN) BALANCE THE FUTURE APPEARS TO LIE IN SUCH INITIATIVES.

I WILL POST AGAIN ON REDUCTIONS ON THE PRODUCTION SIDE OF CO2 - NOT AS GOOD AS HOPED!
