California could benefit from the controversial technology behind “clean coal”
A prominent researcher says it would be foolhardy to abandon plans to siphon off the carbon dioxide from industrial emissions and store it underground. The concept, known widely as “carbon capture and sequestration,” or CCS, has been a slow starter in the U.S. In fact, worldwide, there are only a handful of working projects.
“It never had a chance,” said Sally Benson, following a panel at a major science conference. Benson directs the Global Climate & Energy Project at Stanford University, and is a proponent of CCS — though she says companies that were leading the charge are now “wavering.” She told me that the 2010 UN climate talks in Copenhagen were a turning point; when it became apparent that governments weren’t about to put serious restrictions on carbon emissions, she says investors backed away from CCS, which is still in the pilot stage of development and very pricey.
